Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
FIG. 1 is a flow diagram illustrating a method for profile updating for an application in accordance with an illustrative embodiment. As shown in fig. 1, the method includes, but is not limited to, the following steps:
in step 110, a version number uniquely identifying the configuration file in the configuration file is read, and the configuration file is stored in a first storage address configured in the application program.
The configuration file refers to a file storing configuration information. And the application program deployed on the application node server reads the configuration information in the configuration file to set various software and hardware parameters of the application program.
The version number is code information for recording version information of the configuration file. When the configuration file is updated, the version number is also updated according to the preset rule.
An application refers to a program that provides a network or data service to a user. The application program is deployed in the application node server. The application node server provides platform support for the application program through various software and hardware resources of the application node server. For example, in a web page data crawling application, a user obtains data of interest to the user in a given web page through the web page data crawling application provided by an application node server.
The first storage address refers to an address configured in the application program for storing the configuration file. The application program reads the configuration information in the configuration file through the first storage address, and sets various parameters of the application program according to the read configuration information. If the first storage address for storing the configuration file configured by the application program is modified during the running of the application program, an error of the application program may be caused.
Specifically, the file attribute information of the configuration file stored in the first storage address is read. Wherein the file attribute information of the configuration file comprises the current version number of the configuration file. The unified configuration system uniquely identifies the configuration file associated with the application program through the version number in the file attribute information.
In step 130, when it is sensed that the version number of the new configuration file is higher than the version number of the configuration file, the new configuration file is downloaded to a second storage address.
Specifically, when the application needs to be updated, the configuration file associated with the application on the configuration center server in the unified configuration system is modified. And updating the version of the updated configuration file. And the application node servers of each application program are used for intercepting the configuration files on the configuration center server, and downloading the new configuration files to a second storage address on the application node server if the new configuration files with version numbers higher than that of the configuration files are intercepted.
Wherein the second storage address on the application node server is different from the first storage address configured in the application program. The new configuration file is downloaded through the second storage address, and the reading of the configuration file stored in the first storage address by the application program is not influenced.
In addition, when the application program is updated through the unified configuration system, only the configuration files stored by the configuration center server need to be modified, and the configuration files of all the application node servers do not need to be modified one by one.
In step 150, the configuration information in the downloaded new configuration file is written to the configuration file.
Specifically, the downloaded new configuration file is saved to a second storage address on the application node server. The application node server is used for deploying and running the application program, and the second storage address is different from the first storage address configured in the application program. And when the new configuration file is successfully downloaded to the second storage address, the configuration center server issues a download success indication instruction to the application node server. And the application node server writes the configuration information in the downloaded new configuration file into the configuration file stored in the first storage address according to the downloading success indication instruction.
Furthermore, if the new configuration file is not successfully downloaded, the configuration center server issues a download failure indication instruction to the application node server. At this time, the application node server does not start copying the contents in the second storage address to the first storage address. The application program still reads the configuration file originally in the first memory address. It can be seen that the application node server will only copy the successfully downloaded new configuration file to the first storage address. The operation error of the application program can not be caused by copying the incomplete new configuration file caused by the downloading failure to the first storage address.
Fig. 2 is a diagram illustrating a configuration file update method of an application according to another exemplary embodiment. As shown in fig. 2, including but not limited to the following steps:
in step 101, an application node server receives a configuration file deployment instruction.
When the application program is deployed in the unified configuration system for the first time, the configuration center server receives an application program deployment instruction issued by a user. The user only needs to issue application deployment instructions to the configuration center server of the unified configuration system. And the configuration center server creates a configuration file of the application program and the associated information of the application program according to the deployment instruction of the application program.
In step 103, according to the instruction of the application program deployment instruction, the configuration files located on the configuration center server are downloaded to the first storage addresses on the application node servers, respectively.
And downloading the configuration files located on the configuration center server to the first storage addresses of the application node servers respectively according to the instruction of the application program deployment instruction. Wherein the first storage address refers to a default address of a storage profile configured by the application. When an application program is deployed on a plurality of application node servers for the first time, only the configuration file associated with the application program needs to be created on the configuration center server, and the configuration file of the application program does not need to be created on each application node server.
Fig. 3 is a flowchart illustrating a specific implementation of step 130 in the method according to the corresponding embodiment in fig. 1. As shown in fig. 3, the method includes, but is not limited to, the following steps:
in step 131, reading application configuration associated information located on the configuration center server;
the application configuration related information is a set of a series of information for associating an application program with a configuration file of the application program. The application configuration associated information comprises an IP address of the application node server and an application program identification. The application node server finds the application configuration associated information corresponding to the IP address of the application node server according to the IP address of the application node server, and acquires the application configuration associated information by accessing the configuration center server.
Furthermore, the application node server of the application program to be updated can be specified through the configuration center server, and the configuration center server only issues the version updating instruction to the specified application node server. And only the application node server receiving the version updating instruction reads the application configuration associated information on the configuration center server.
In step 133, the new configuration file is downloaded to the second storage address on the application node server according to the indication of the application configuration association information.
Specifically, the application node server downloads the new configuration file to the second storage address on the application node server by matching the own IP address with the IP address indicated by the application configuration association information. The second storage address is recorded in the address information in the application configuration association information. And the application node server downloads the new configuration file to a local second storage address according to the address information recorded by the application configuration associated information.
And after the downloading of the new configuration file is completed, writing the configuration information in the new configuration file into a first storage address configured in the application program. When the application program is in a running state, only the configuration file in the first storage address needs to be accessed. When the application program is in a running state, the running error of the application program caused by the fact that the configuration address in the application program needs to be modified when the configuration file is updated is avoided.
Fig. 4 is a flowchart illustrating a specific implementation of step 150 in the method according to the corresponding embodiment in fig. 1. As shown in fig. 4, the method comprises the steps of:
in step 151, the second storage address is address-associated with the file storage path of the configuration file in the first storage address.
In a specific embodiment, the second storage address is mounted under the configuration file of the application program by means of mounting. The content stored in the second memory address is accessible when the application accesses the configuration file.
In step 153, the configuration information in the second storage address is written to the configuration file by address association.
Specifically, the second storage address is mounted under the folder where the configuration file is located through a mounting command supported by the Linux system or the windows system, so that the second storage address is associated with the folder directory. When the application accesses this folder, it is equivalent to accessing the second storage address.
Fig. 5 is a diagram illustrating a configuration file update method of an application according to another exemplary embodiment. As shown in fig. 5, the following steps are included, but not limited to:
in step 170, the configuration information in the configuration file is read by accessing the configuration file.
The configuration information refers to a set of information used for instructing the application program to set various software and hardware parameters of the application program. The application program meets the requirements of the application program on software and hardware system resources by setting software and hardware parameters. For example, the URL points to an address, a web browser port, a cache size, and the like.
Specifically, when the application program is deployed for the first time, the application program may automatically generate the configuration file. The configuration file is used for storing configuration information of the application program. And the application program reads the configuration information in the configuration file by accessing the configuration file.
In a specific embodiment, in the Linux running environment, the second storage address is mounted under the configuration folder in the first storage address through a mount command supported by Linux. At this time, the application program can access the configuration information in the new configuration file in the second storage address by accessing the configuration folder in the first storage address.
In step 190, the application itself is set according to the read configuration information, and the application is updated by the setting.
When the application content of the application changes, the configuration file of the application also needs to be updated according to the changed content. At this time, the application program sets itself according to the read configuration information, and updates the application program itself by the setting.
In a specific embodiment, when an application changes, the configuration information corresponding to the application is also modified accordingly. For example, a web page data crawling application changes from a surf homepage to a hundredth news homepage. The address pointed by the configuration information URL in the configuration file needs to be modified from the newwave homepage address to the hundredth news homepage address. And the application program sets the URL pointing address of the application program according to the configuration information of the data capturing address information, and updates the application program through the setting.
Fig. 6 is a topology diagram illustrating a configuration file update method of an application program according to another exemplary embodiment. As shown in fig. 6, the configuration information and the application configuration association information are stored in the configuration center server. And the application node server downloads the configuration information of the new version to the second storage address through the configuration agent device, and then mounts the second storage address to the folder where the configuration file in the first storage address configured by the application program is located.
When the application program accesses the configuration file to obtain the updated configuration information, the storage address where the configuration file is located does not need to be modified, and the stable operation of the program is ensured.
