FIG. 3 shows an exemplary implementation of a related device involved in the application deployment method, including an application deployment device 310, an application cluster 320 including multiple application servers, an elastic extension service platform 330, and a user local working device 340. . The application deployment device 310 is configured to execute the application deployment method, and apply the application deployment to the application server. The application server is configured to run the related application after the application deployment is completed. The user local working device 340 is a device for the user to interact with the application deployment device 310, and is used for providing the user with the installation configuration package, related information during initial deployment, and the like. The flexible telescopic service platform 330 can adjust the computing resources in the cloud resource pool, and allocate the servers in the cloud resource pool to the application according to the current needs of the application, so that the application server to be deployed can be determined, thereby obtaining online configuration information, and The obtained online configuration information is provided to the application deployment device 310 for flexible deployment. In an actual application, the specific implementation of the elastic scalability service platform 330 may be determined by a service provider, such as an ESS (Elastic Scaling Service) provided by the Alibaba Cloud platform.

Preferably, the obtaining the online configuration information includes: sending an inquiry request to the elastic extension service platform, and receiving online configuration information sent by the elastic extension service platform according to the query request, wherein the elastic extension platform is based on the application The requirement determines the application server to be deployed currently; or receives a push message sent by the elastic extension service platform that includes the online configuration information. For example, if the application deployment device uses the push service, the application deployment device may receive the push message by using the elastic extension service platform, where the push message includes online configuration information, and the push message can be obtained by parsing the push message. On-line configuration information is used for application deployment. If the application deployment device does not use the push service, you can send a query request to the elastic extension service platform periodically (for example, every two seconds) to query the online configuration information. Feedback, get online configuration information. According to different application scenarios, online configuration information can be obtained in different ways to improve the versatility of the solution.

For example, if an application is played by a certain video, if the number of application servers for which the application is currently deployed is five, the information about the five application servers will be stored in the local configuration information, including the IP of the application server and the number of application servers. . Whenever there is a popular program to play, the load of the server will be significantly increased due to more viewers, which may cause the server to crash and affect the user's viewing experience. Therefore, the application needs to be deployed on other new application servers to share the load of the current application server. For example, a total of seven application servers are required to meet the current load requirements, and an online line containing information about the seven application servers is obtained. Configuration information. By comparing with the local configuration information, the newly added application server is deployed to meet the current requirements of the application, and the content in the local configuration information is updated to the related content of the seven application servers.

In addition, in the foregoing scenario, the following situation may also exist. When the popular program is played, the number of viewers may be reduced. At this time, using 7 application servers may cause waste of computing resources. So according to this time The application needs reduce the number of application servers and increase the utilization of computing resources. For the foregoing remote application configuration method, after the online configuration information is acquired, if the online configuration information is different from the local configuration information, and there is no new application server in the online configuration information, according to the online configuration The information updates the local configuration information. When the online configuration information is different from the local configuration information, and there is no new application server in the online configuration information, the number of application servers to be deployed determined according to the current needs of the application is compared with the current The number of application servers deployed by the application is reduced. For the application deployment device, only the local configuration information needs to be updated according to the online configuration information.

In the actual application, the specific processing steps of an application deployment device for application deployment are as shown in FIG. 4, and the following steps are included:

Step S401: Acquire initial configuration information of the application and a corresponding installation configuration package install.tgz, and thereby complete initial deployment of the application server. For information about the application server that has been deployed for the initial deployment, you can save the file topo.conf as local configuration information.

In step S402, it is determined whether to use the push service. If the push service is used, step S403 is performed; if the push server is not used, step 404 is performed.

Step S403, receiving the elastic extension service platform push message, and obtaining the online configuration information from the push message, and then performing step S405.

Step S404, the query request is sent to the elastic extension service platform, and the online configuration information is obtained according to the feedback, and then step S405 is performed.

In step S405, the online configuration information is compared with the local configuration information. If the two are the same, the device waits for the set time, and then returns to step S402. If the two are different, step S406 is performed.

Step S406, determining whether there is a new application server in the online configuration information, and if yes, executing step S407; if not, executing step S408.

In step S407, the application deployment is performed on the newly added application server by using the installation configuration package install.tgz, and then step S408 is performed.

Step S408, updating the file topo.conf storing the local configuration information according to the online configuration information, and then returning to step S402.

As a preferred implementation manner of the embodiment of the present application, the application deployment of the newly added application server includes: sending the installation configuration package of the application to an application server of a type corresponding to the application type, and according to the The installation configuration package performs application deployment on the application server. Different server clusters can be defined by defining different types of application servers, so that different applications can be deployed in different server clusters. The application is integrated into the corresponding type of application server to facilitate the management of the server cluster. In this embodiment, the cluster of the application server and the application server are respectively defined using roledefs and roles. The specific format is:

Roledefs={'apphosts':[‘host1','host2','host3'],'webhosts':['host3','host4']}

$roles('apphosts')

@task1

Run('/root/install_app.sh)

$roles('webhosts')

@task2

Run('/root/install_web.sh')

The cluster of two application servers is defined in the above manner: cluster 1 "apphosts", which contains three application servers host1, host2, and host3. Task 1 (task1) is executed on the application server belonging to the "apphosts" cluster. The specific task is to install the app. Application (run('/root/install_app.sh)); cluster 2 "apphosts", which contains two application servers host3 and host4, and performs task 2 (task2) on the application server belonging to the "webhosts" cluster. The specific task is to install the web. Application (run('/root/install_web.sh')). By clustering the application servers, you can deploy different types of applications on different types of application servers at the same time. This implementation is more suitable for complex application scenarios of cloud computing.

In actual applications, if you need to deploy applications to a large number of application servers at once, if you use sequential deployment, it will consume time resources. For example, in the method shown in FIG. 1, the application deployment device uploads the installation configuration package to the application server 1, and deploys the application on the application server 1, and then the application deployment device sequentially goes to the remaining application servers 2 to N according to the previous step. For application deployment, the time for application deployment to N application servers is T×N, where T is the time required for application deployment to one server. Since the application deployment process between application servers is independent of each other, concurrent application deployment to all application servers does not adversely affect the entire application deployment process, and theoretically, an application is deployed concurrently on N application servers. The required deployment time is only T, which can save (N-1)/N time compared to the sequential execution deployment mode, which will greatly improve the efficiency of application deployment. Specifically, the application deployment of the newly added application server includes: sending the installation configuration package of the application to a plurality of newly added application servers, and performing application deployment on the application server according to the installation configuration package.

FIG. 5(a) and FIG. 5(b) are schematic diagrams showing the deployment manner and the concurrent deployment mode of the foregoing sequence. In Figure 5(a), two deployment tasks for application deployment of three application servers are used as an example. The deployment task task1 of application 1 deploys application 1 in host1, host2, and host3 in turn. In Execute the deployment task task2 of application 2. The task2 will deploy application 2 in host1, host2, and host3 in turn, assuming that application 1 and application 2 are deployed on each application server for the same time, both are T. The total deployment time requires 6T. In the scenario of concurrent execution shown in 5(b), the deployment task task1 of application 1 deploys application 1 in host1, host2, and host3 at the same time. After task1 is completed, the deployment task task2 of application 2 is also on host1. Application 2 is deployed on host2 and host3. Therefore, the total deployment time of this method is 2T, and the deployment efficiency is significantly improved.

As a more preferred implementation manner, the foregoing manner of deploying an application according to an application server type may be combined with a manner of concurrent deployment, and a logical processing flow thereof is shown in FIG. 6. In practical applications, the roles variable in the configuration information can be used to determine whether the corresponding type is set. If there is a roles variable, the application server of the corresponding type can be determined according to the roles variable, and then according to the parallel variable in the configuration information of the application. To determine if the deployment of the application can proceed concurrently. If the roles variable is 'apphosts', and the application can be executed concurrently (ie, the parallel variable is enabled), the installation configuration package of the application is simultaneously sent to multiple application servers of a type corresponding to the type of the application, And performing application deployment on the application server according to the installation configuration package, that is, sending the installation configuration package of the application to the host1, host2, and host3 at the same time, and simultaneously installing the configuration package on the host1, the host2, and the host3 according to the installation configuration package. Apply for application deployment. If the application is not executable concurrently (that is, the parallel variable is not enabled), the installation configuration package of the application is sequentially sent to multiple application servers of a type corresponding to the type of the application, and sequentially according to the installation configuration package. The application server performs application deployment, that is, the installation configuration package of the application is sent to the host1, and the application configuration is performed according to the installation configuration package, and then the installation configuration package is sent to the host2 and the application deployment is performed on the host2. Finally, send the configuration package to host3 and deploy the application to host3.

In the case where the roles variable does not exist, it means that the application needs to be deployed on an application server of an undefined type. In this embodiment, the application server defined by the hosts variable represents the application server. Therefore, if there is no roles variable, and the application can be executed concurrently, the installation configuration package of the application is simultaneously sent to the application server defined by the plurality of hosts variables, and the installation configuration package is sequentially performed according to the installation configuration package. The application server is used for application deployment. If the roles variable does not exist, and the application is not executable concurrently, the installation configuration package of the application is sequentially sent to an application server defined by multiple hosts variables, and the application server is sequentially performed according to the installation configuration package. Application deployment.

In addition, considering the multi-thread security problem, when concurrently deploying multiple application servers, a multi-process approach can be adopted. And performing the application deployment on the application server according to the installation configuration package, specifically: creating a child process for each application server, and controlling the child process to respectively apply the application according to the installation configuration package The server performs application deployment; and obtains an application deployment result of each application server sent by the child process. For example, as shown in Figure 7, the application process of the three application servers in the "apphosts" cluster is as shown in Figure 7. If the application process is deployed, the main process in the application deployment device determines that the application can be executed concurrently. Obtain the information of the newly added application server in the online configuration information and complete the preparation of the installation configuration package; then create a corresponding sub-process for each application server, for example, three application servers host1, host2 for the "apphosts" cluster and Host3 creates sub-process 1, sub-process 2, and sub-process 3, respectively. Each sub-process is responsible for application deployment, management and control of the corresponding application server, and different sub-processes do not affect each other. After the sub-process is created, the main process indicates that the sub-process 1, sub-process 2, and sub-process 3 are deployed on the host1, host2, and host3. After the application is deployed, the sub-process sends the application deployment result to the main process. When the main process collects the application deployment results of all the sub-processes, the results are summarized and sent to the local working device to complete the feedback to the user.

In the actual application, the application deployment of the newly added application server includes: obtaining the login user name and the login password of the application server, logging in to the application server according to the login user name and the login password; and instructing the application server to be installed. The installation configuration package of the application. When the application server is deployed for application, you can log in to the corresponding application server by using the login user name and login password to obtain the permission to install the configuration package of the related application on the application server, thereby ensuring the security of the network environment. For a scenario with a large cluster size, the number of application servers included in the cluster is large. Therefore, there are many login user names and login password input requirements during the deployment process. In order to reduce the login user name and login password of the user management application server. The difficulty is that the login user name of the application server is obtained according to one of the following priority order in the embodiment of the present application. For details, refer to FIG. 8( a ):

1. Obtain the login user name of the application server from the input information of the command line. The user name entered by the command line is the highest priority. When it is detected that the user enters the login user name from the command line, the login user name is extracted directly from the command line, and the login user name is used to try to log in to the application server.

2. Obtain the login user name of the application server from the preset file. The priority of the method is lower than the login user name of the application server obtained by the input information of the command line, where the preset file may be a configuration description file in the installation configuration package, or may be the user during the initial configuration process. The content in the initial configuration information uploaded to the app deployment device. The login user name of the application server can be saved by a related variable in the preset file. For example, in this embodiment, the login user name is saved by two variables in the preset file, respectively, a user variable and a hosts variable, where hosts The variables respectively define different login user names for different application servers, and may be in the form of a correspondence table between the identifier of the application server (for example, an IP address) and the login user name of the application server. When the hosts variable exists, the application server is acquired. Login user name, and determine whether the application server currently exists, At this point, the login user name of the application server is extracted from the hosts variable. The user variable uniformly defines a login user name. When the hosts variable does not exist or the application server in the hosts variable is not online at present, the login user name is extracted from the user variable, so the priority of the user variable is lower than the hosts variable. .

3. Obtain the username of the local device as the login user name of the application server. If the login user name is not obtained from the command line, and the hosts variable and the user variable are not present, the user name of the local device is obtained as the login user name of the application server by default. The local device may be a device that the user interacts with the application deployment device. For example, in the typical implementation of FIG. 3, the local device is the user local working device 340.

After the application deployment device obtains the login user name by any of the foregoing methods, it will continue to obtain the login password. The login password of the application server is obtained according to one of the following priority sequences. For details, refer to FIG. 8(b):

1. Obtain the login password of the application server from the input information of the command line. The password entered by the command line is the highest priority. When it is detected that the user enters the login password from the command line, the login password is directly extracted by the command line, and the login user name is used to log in to the application server.

2. Obtain the login password of the application server from the preset file. The priority of the method is lower than the login password of the application server obtained by the input information of the command line. The login password of the application server can also be saved by the relevant variable in the preset file. For example, in this embodiment, Set two variables in the file to save the login password, which are passwords and password variables respectively. The passwords variable respectively define different login passwords for different application servers, which can be the application server identifier (such as IP address) and application server. In the form of the correspondence table of the login password, when the password variable exists, the login password of the application server is obtained, and it is determined whether the application server currently exists. At this time, the login password of the application server is extracted from the passwords variable. The password variable defines a login password. When the password variable does not exist or the application server in the passwords variable is not online, the login password is extracted from the password variable. Therefore, the priority of the password variable is lower than the password variable.

3. The login password of the application server is obtained by the cache of the local device. Similar to when the login user name is obtained, when the login password is not obtained from the command line, and the password variable and the password variable are not present, the password is obtained from the cache of the local device as the login password of the application server.

4. Obtain a password input by the local device as the login password of the application server. When no password is saved in the cache of the local device, the user with the lowest priority will require the user to enter the password from the local device.

In this embodiment, the login user name and the login password are all entered with the command line as the highest priority, which is in accordance with the user's usage habits. In addition, the general user will record the commonly used login user name and login password in the default file. Manual input via the local device is only possible in a small number of special cases. Therefore, the way to obtain the login user name and password in this way can satisfy the user's use requirements to the greatest extent, and provides convenient and efficient application deployment.

Specifically, the configuration obtaining apparatus 910 is configured to acquire online configuration information, where the online configuration information includes an application server to be deployed determined according to an current requirement of the application; and the deployment apparatus 920 is configured to If the configuration information is different from the local configuration information, and the new configuration server is added to the online configuration information, the application deployment is performed on the newly added application server, and the local configuration information is updated according to the online configuration information. The local configuration information includes an application server that has been deployed by the application.

The device is especially suitable for the scenario where the initial deployment of the application has been completed and the dynamic elastic adjustment is performed during the subsequent operation and maintenance. If the initial deployment of the application is required, the configuration obtaining device 910 obtains information about the application server that needs to be deployed by the user and the corresponding installation configuration package, and completes the application server by the deployment device 920. Initial deployment. For application servers that have been deployed for application during initial deployment, they can be saved as local configuration information.

After the initial deployment is completed, the configuration obtaining device 910 can dynamically obtain the online configuration information of the application server to be deployed determined according to the current requirement of the application, and compare with the local configuration information to find that the new application server needs to be deployed. Afterwards, the application device 920 deploys the application servers to implement the flexible deployment of the application, and the flexibility of the deployment solution is improved. At the same time, the original local configuration information is updated through the online configuration information, and the current application is applied. The deployed application server records to ensure the accuracy of subsequent application deployment.

Here, those skilled in the art should understand that the above application deployment device may include, but is not limited to, a user equipment, a network device, or a device formed by integrating a user equipment and a network device through a network. The user equipment includes, but is not limited to, a personal computer, a touch terminal, and the like; the network device includes, but is not limited to, a network host, a single network server, a plurality of network server sets, or a cloud computing-based computer set. Here, the cloud is composed of a large number of host or network servers based on Cloud Computing, which is a kind of distributed computing, a virtual computer composed of a group of loosely coupled computers.

FIG. 3 shows an exemplary implementation of a related device involved in the application deployment of the application deployment device, including an application deployment device 310, an application cluster 320 including multiple application servers, an elastic extension service platform 330, and a user local. Work equipment 340. The application deployment device 310 is configured to perform application deployment on the application server according to the configuration information. The application server is configured to run the related application after the application deployment is completed. User The ground working device 340 is a device for the user to interact with the application deployment device 310, and is used for providing the user with the installation configuration package, related information during initial deployment, and the like. The elastic extension service platform 330 can determine the application server to be deployed according to the current needs of the application, and obtain the online configuration information, and provide the obtained online configuration information to the application deployment device 310 for flexible deployment. In an actual application, the specific implementation of the elastic scalability service platform 330 may be determined by a service provider, such as an ESS (Elastic Scaling Service) provided by the Alibaba Cloud platform.

Preferably, the configuration obtaining device 910 is specifically configured to send a query request to the elastic scalability service platform, and receive online configuration information sent by the elastic extension service platform according to the query request, where the elastic scalability platform is used according to an application. The requirement determines the application server to be deployed currently; or receives a push message sent by the elastic extension service platform that includes the online configuration information. For example, if the application deployment device uses the push service, the application deployment device may receive the push message by using the elastic extension service platform, where the push message includes online configuration information, and the push message can be obtained by parsing the push message. On-line configuration information is used for application deployment. If the application deployment device does not use the push service, you can send a query request to the elastic extension service platform periodically (for example, every two seconds) to query the online configuration information. Feedback, get online configuration information. According to different application scenarios, online configuration information can be obtained in different ways to improve the versatility of the solution.

In addition, in the foregoing scenario, the following situation may also exist. When the popular program is played, the number of viewers may be reduced. At this time, using 7 application servers may cause waste of computing resources. Therefore, the number of application servers can be reduced according to the requirements of the application at this time, and the utilization of computing resources can be improved. For the foregoing remote application configuration device, after the configuration obtaining device 910 obtains the online configuration information, the deployment device 920 is further configured to: if the online configuration information is different from the local configuration information, and the online configuration information is not added. The application server updates the local configuration information according to the online configuration information. When the online configuration information is different from the local configuration information, and there is no new application server in the online configuration information, the number of application servers to be deployed determined according to the current needs of the application is compared with the current The number of application servers deployed by the application is reduced, for the application department The device only needs to update the local configuration information according to the online configuration information.

Step S401, the configuration obtaining device acquires initial configuration information of the application and the corresponding installation configuration package install.tgz, and thereby completes initial deployment of the application server. For information about the application server that has been deployed for the initial deployment, you can save the file topo.conf as local configuration information.

In step S402, the configuration obtaining means determines whether to use the push service. If the push service is used, step S403 is performed; if the push server is not used, step 404 is performed.

Step S403, the configuration obtaining device receives the elastic extension service platform push message, and obtains the online configuration information from the push message, and then performs step S405.

Step S404, the configuration obtaining device sends a query request to the elastic scalability service platform, and obtains online configuration information according to the feedback, and then performs step S405.

In step S405, the configuration obtaining device compares the online configuration information with the local configuration information. If the two are the same, after waiting for the set time, the process returns to step S402. If the two are different, step S406 is performed.

Step S406, the configuration obtaining means determines whether there is a new application server in the online configuration information, and if so, executing step S407; if not, executing step S408.

In step S407, the deployment device deploys the application to the newly added application server by using the installation configuration package install.tgz, and then performs step S408.

Step S408, the configuration obtaining device updates the file topo.conf that saves the local configuration information according to the online configuration information, and then returns to step S402.

As a preferred implementation manner of the application, the deployment device 920 is specifically configured to send an installation configuration package of the application to a type of the application when the application deployment is performed on the newly added application server. Corresponding types of application servers, and applying applications to the application servers according to the installation configuration package. By defining different types of application servers to divide different server clusters, different applications can be deployed in different server clusters, and the same type of applications can be integrated into corresponding types of application servers to facilitate management of server clusters. In this embodiment, the cluster of the application server and the application server are respectively defined using roledefs and roles. The specific format is:

Roledefs={'apphosts':[‘host1','host2','host3'],'webhosts':['host3','host4']}

$roles('apphosts')

@task1

Run('/root/install_app.sh)

$roles('webhosts')

@task2

Run('/root/install_web.sh')

In actual applications, if you need to deploy applications to a large number of application servers at once, if you use sequential deployment, it will consume time resources. For example, in the solution shown in FIG. 1 , the application deployment device uploads the installation configuration package to the application server 1 , and deploys the application on the application server 1 , and then the application deployment device sequentially runs on the remaining application servers 2 to N according to the previous step. For application deployment, the time for application deployment to N application servers is T×N, where T is the time required for application deployment to one server. Since the application deployment process between application servers is independent of each other, concurrent application deployment to all application servers does not adversely affect the entire application deployment process, and theoretically, an application is deployed concurrently on N application servers. The required deployment time is only T, which can save (N-1)/N time compared to the sequential execution deployment mode, which will greatly improve the efficiency of application deployment. Specifically, the deployment device 920 is configured to send an installation configuration package of the application to a plurality of newly added application servers when the application deployment is performed on the newly added application server, and simultaneously perform the installation according to the installation configuration package. The application server is used for application deployment.

FIG. 5(a) and FIG. 5(b) are schematic diagrams showing the deployment manner and the concurrent deployment mode of the foregoing sequence. In Figure 5(a), two deployment tasks for application deployment of three application servers are used as an example. The deployment task task1 of application 1 deploys application 1 in host1, host2, and host3 in turn. After executing the deployment task task2 of the application 2, the task2 will deploy the application 2 in the host1, the host2, and the host3 in turn, assuming that the application 1 and the application 2 are deployed on each application server for the same time, both are T. The total deployment time of the mode requires 6T. In the scenario of concurrent execution shown in 5(b), the deployment task task1 of application 1 deploys application 1 in host1, host2, and host3 at the same time. After task1 is completed, the deployment task task2 of application 2 is also on host1. Application 2 is deployed on host2 and host3. Therefore, the total deployment time of this mode is 2T. Significantly improved.

As a more preferred implementation manner, the foregoing manner of deploying an application according to an application server type may be combined with a manner of concurrent deployment, and a logical processing flow thereof is shown in FIG. 6. In practical applications, the roles variable in the configuration information can be used to determine whether the corresponding type is set. If there is a roles variable, the application server of the corresponding type can be determined according to the roles variable, and then according to the parallel variable in the configuration information of the application. To determine if the deployment of the application can proceed concurrently. When the application device 920 deploys the application to the newly added application server, specifically: if the roles variable is 'apphosts', and the application can be executed concurrently (ie, the parallel variable is enabled), Sending the installation configuration package of the application to a plurality of application servers of a type corresponding to the type of the application, and performing application deployment on the application server according to the installation configuration package, that is, simultaneously installing the configuration package of the application Send to the host1, host2, and host3, and deploy the application to the host1, host2, and host3 according to the installation configuration package; if the application cannot be executed concurrently (that is, the parallel variable is not enabled), the application is sequentially The installation configuration package is sent to a plurality of application servers of a type corresponding to the type of the application, and the application server is deployed in the application according to the installation configuration package, that is, the installation configuration package of the application is sent to the host1, and according to After the installation configuration package is applied to the host1, the installation configuration package is sent to the host2 and the application deployment is performed on the host2, and finally the installation is performed. The configuration package is sent to and host3 and application deployment is performed on host3.

In the case where the roles variable does not exist, it means that the application needs to be deployed on an application server of an undefined type. In this embodiment, the application server defined by the hosts variable represents the application server. Therefore, when the application device 920 deploys the application to the newly added application server, if the role variable is not present, and the application can be executed concurrently, the installation configuration package of the application is sent at the same time. And in the application server defined by the plurality of hosts variables, and applying the application to the application server according to the installation configuration package; if there is no roles variable, and the application cannot be executed concurrently, the application is sequentially The installation configuration package is sent to an application server defined by multiple hosts variables, and the application server is deployed in an application according to the installation configuration package.

In addition, considering the multi-thread security problem, when concurrently deploying multiple application servers, a multi-process approach can be adopted. The deployment device 920 is specifically configured to create a sub-process for each application server when the application is deployed to the application server according to the installation configuration package, and the sub-process is controlled according to the installation configuration package. The application server is used for application deployment; and the application deployment result of each application server sent by the child process is obtained. For example, the processing flow of the application server 920 in the application deployment device is determined by the process of deploying the application in the application deployment device. The application can execute concurrently, obtain the information of the newly added application server in the online configuration information and complete the preparation of installing the configuration package; then create a corresponding sub-process for each application server, for example, three applications for the "apphosts" cluster. The server host1, host2, and host3 create sub-process 1, sub-process 2, and sub-process 3, respectively. Each sub-process is responsible for application deployment, management and control of the corresponding application server, and different sub-processes do not affect each other. After the sub-process is created, the main process indicates that the sub-process 1, sub-process 2, and sub-process 3 are deployed on the host1, host2, and host3. After the application is deployed, the sub-process sends the application deployment result to the main process. When the main process collects the application deployment results of all the sub-processes, the results are summarized and sent to the local working device to complete the feedback to the user.

In an actual application, the deployment device is configured to acquire a login user name and a login password of the application server, and log in to the application according to the login user name and login password. a server; instructing the application server to install an installation configuration package of the application. When the application server is deployed for application, you can log in to the corresponding application server by using the login user name and login password to obtain the permission to install the configuration package of the related application on the application server, thereby ensuring the security of the network environment. For a scenario with a large cluster size, the number of application servers included in the cluster is large. Therefore, there are many login user names and login password input requirements during the deployment process. In order to reduce the login user name and login password of the user management application server. Difficulty, the login user name of the application server in the embodiment of the present application is obtained according to one of the following priority order:

2. Obtain the login user name of the application server from the preset file. The priority of the method is lower than the login user name of the application server obtained by the input information of the command line, where the preset file may be a configuration description file in the installation configuration package, or may be the user during the initial configuration process. The content in the initial configuration information uploaded to the app deployment device. The login user name of the application server can be saved by a related variable in the preset file. For example, in this embodiment, the login user name is saved by two variables in the preset file, respectively, a user variable and a hosts variable, where hosts The variables respectively define different login user names for different application servers, and may be in the form of a correspondence table between the identifier of the application server (for example, an IP address) and the login user name of the application server. When the hosts variable exists, the application server is acquired. The login user name, and determine whether the application server currently exists. At this time, the login user name of the application server is extracted from the hosts variable. The user variable uniformly defines a login user name. When the hosts variable does not exist or the application server in the hosts variable is not currently online, it is used by the user. The login user name is extracted from the variable, so the user variable has a lower priority than the hosts variable.

After the application deployment device obtains the login user name by any of the foregoing methods, it will continue to obtain the login password. The login password of the application server is obtained according to one of the following priority order:

In this embodiment, the login user name and the login password are all entered with the command line as the highest priority, which is in accordance with the user's usage habits. In addition, the general user will record the commonly used login user name and login password in the default file, and only manually input through the local device in a small number of special cases. Therefore, the way to obtain the login user name and password in this way can satisfy the user's use requirements to the greatest extent, and provides convenient and efficient application deployment.

In summary, after completing the initial deployment, the technical solution of the present application can dynamically obtain the online configuration information of the application server to be deployed determined according to the current needs of the application, and compare with the local configuration information to find that there is a new one. After the application server needs to be deployed, apply the application deployment to these new application servers to implement flexible deployment of the application, improve the flexibility of the deployment solution, and update the original local configuration information through online configuration information. The application server that performs application deployment records to ensure the accuracy of subsequent application deployment.
