Detailed Description
The scheme provided by the specification is described below with reference to the accompanying drawings.
In a first aspect, an embodiment of the present invention provides an application deployment method in an elastically scalable cluster service, where the method is executed by a cloud management platform, and referring to fig. 1, the method includes the following steps:
after receiving the notification of the completion of the node expansion, calling an entry script in the newly added node to enable the entry script to execute the following steps: acquiring application related parameters from a preset relational database, acquiring corresponding application installation packages and deployment scripts from an object repository according to the application related parameters, and controlling the deployment scripts to execute so as to realize the installation and deployment of the application installation packages on the newly added nodes;
the preset relational database is used for storing at least one application related parameter of an application installation package in advance, and the object storage library is used for storing the application installation package and the deployment script in advance.
It can be understood that, before executing the method, a preset relationship database needs to be constructed, referring to fig. 2, application-related parameters are stored in the preset relationship database, and the application-related parameters may include information such as an application name, an application version number, a path of an installation package, and a path of a script. That is, parameters required for deployment or other operations, such as application name, application type, application version number, installation package and storage path of script in the object repository, etc., are saved in the preset relational database.
It can be understood that before executing the method, an object repository needs to be constructed, referring to fig. 2, the application installation package and the deployment script are stored in the object repository, and of course, a plurality of scripts such as a start script, an initialization script, a stop script, an upgrade script, and the like may also be stored in the object repository. Therefore, before the method is executed, program installation packages deployed by the application need to be collected, relevant operation scripts are written in sequence according to the installation method, and the installation packages and the scripts are uploaded to an object storage library.
It can be understood that after the elastically scalable cluster service completes the node expansion, one or more newly added nodes are added to the elastically scalable cluster service, and application deployment is required for each newly added node. When the cloud management platform knows that the nodes are completely expanded, the cloud management platform calls an entry script in the newly added nodes, the entry script serves as a universal script, and the cloud management platform has the following functions: and acquiring application related parameters from a preset relational database, and further acquiring corresponding application installation packages and deployment scripts from an object repository according to the application related parameters. The application installation package is an installation package of an application to be deployed, and the deployment script is used for installing and deploying the application installation package. Therefore, after the entry script acquires the application installation package and the deployment script, the deployment script is controlled to be executed, so that the application installation package is installed and deployed on the newly added node, and the whole process does not need manual intervention.
The entry script in the newly added node has multiple setting modes, and the following two modes are provided:
(1) and pre-adding an entry script in the mirror image of the elastic telescopic cluster service, so that each newly added node after expansion comprises the entry script. That is, the entry script is written in the mirror image of the elastic scalable cluster service in advance, and after the node expansion is performed, each obtained new node will have the entry script by default. This approach is relatively simple to implement.
(2) And before the entry script in the newly added node is called, sending the entry script to the newly added node. That is to say, after the elastically scalable cluster service completes the node expansion, the cloud management platform puts the entry script on the newly added node, so that the newly added node has the entry script. This approach may involve a related adaptation of the cloud management platform, which is more complex than the direct mirror modification approach.
In particular implementation, the at least one application-related parameter may include: the application attribute information, the storage path of the application installation package in the object storage library and the storage path of the deployment script in the object storage library; the application attribute information includes an application name, an application type, and/or an application version number.
The application attribute information is basic information of the application. Which application is installed and deployed can be determined according to the basic information, and which installation package and script are obtained can be determined according to the storage path.
It is understood that after the deployment of the application installation package is completed using the deployment script, other operations may also be completed in accordance with other scripts in the object store. For example, by executing a start script, the start of an application can be achieved. By executing the initialization script, the initialization processing of the application can be realized. And executing the stop script to realize the stop of the running of the application. And the upgrading script is executed, so that the upgrading of the application can be realized.
In particular implementation, the object repository may be further configured to store a startup script in advance; the method may further comprise: and after the application deployment is finished, controlling the starting script to execute through the entrance script so as to realize the starting of the application. That is, after the deployment script is executed, the entry script may control the start script to execute, so as to start the application.
In particular implementation, the object repository may be further configured to store an initialization script in advance; the method may further comprise: after the application is started, the execution of the initialization script is controlled through the entry script so as to realize the data initialization of the application. That is, after the start of the application is realized by the start script, the entry script controls the execution of the initialization script, thereby realizing the data initialization processing for the application.
In particular implementation, the object repository may be further configured to store an upgrade script in advance; the method may further comprise: and when an upgrading instruction is received, controlling the upgrading script to execute through the entry script so as to realize the upgrading of the application. That is, when the application needs to be upgraded, the entry script can control the execution of the upgrade script, so as to upgrade the application.
In particular implementation, the object repository may be further configured to pre-store a stop script; the method may further comprise: and when a stop instruction is received, controlling the stop script to execute through the entry script so as to realize the stop running of the application. That is, when it is necessary to stop the running of the application, the entry script may control the stop script to execute, thereby controlling the stop of the running of the application.
It can be understood that when the application program load is low and the nodes need to be reduced, the nodes needing to be reduced can be automatically deleted, so that the computing and storage resources of the server can be completely released, and the rest nodes can continue to provide services without influencing the service use.
It can be understood that when an emergency causes a high load of an application program, a cluster automatically expands nodes after detecting the high load, no application is deployed on the node which is just expanded, a notification is sent to the cloud management platform after the expansion is completed to inform that a new node is expanded, and the cloud management platform automatically calls an entry script of the node, so that the deployment of the application is realized. After the application is started, the newly expanded nodes are added into the cluster of the application program to share the load of the program, and the service is provided for the outside.
After the nodes are automatically expanded by the elastically stretchable cluster service, no application is deployed on the newly expanded nodes, after the expansion nodes are completed, the cloud management platform can automatically call the entry scripts on the newly added nodes, then the entry scripts can acquire application related parameters stored in the relational database, the entry scripts of the newly added nodes can automatically download the application installation packages and the deployment scripts in the object storage library according to the parameters, and after the deployment scripts are executed, deployment of the application is completed. Of course, the entry script may call an initialization script, a start script, and the like to complete initialization, start, and the like of the application. And adding the newly added nodes after application deployment into the application program cluster, sharing the load of the application program, and providing service to the outside. The whole process does not need manual intervention, can respond in time in the face of sudden high load conditions, and can save manpower.
It can be understood that the method provided by the embodiment of the invention can realize automatic deployment and management of applications, when the load of an application program fluctuates in height, the number of nodes of a cluster can be automatically expanded, and when the number of nodes is automatically expanded, a required application program can be automatically deployed, so that server resources are not wasted, and abnormality caused by overhigh application load is avoided, and the aim of efficiently utilizing the server resources is fulfilled; and the whole process is automatically completed without manual intervention, thereby reducing the possible errors of manual operation and improving the reliability of the system. Meanwhile, the labor cost is saved, the deployment speed is increased, and the robustness of the program and the response speed to abnormal conditions are improved.
