In this embodiment, the method for upgrading and maintaining the cluster includes:

S1. Upload the new version of the software package and the new configuration file that need to be released to the preset release machine.

In the embodiment of the present application, the software package includes a jar package. The jar package is also called JAR file (Java Archive, English: Java Archive) is a software package file format, usually used to aggregate a large number of Java class files, related metadata and resource (text, pictures, etc.) files into A file to develop application software or libraries for the Java platform. The new configuration file includes: operating environment parameters, interface parameters, address parameters, and so on.

In at least one embodiment of the present application, the new version of the jar package and the new configuration file that need to be released are determined by the version of the cluster node server. If the updated version of a certain cluster node server is 1.7, the updated version The content is the new version of the jar package and the new configuration file to be released. The preset publishing machine performs functional operations by using a web interface, and is used to perform version publishing of the cluster node server.

Preferably, the embodiment of the present application uploads the new version jar package and the new configuration file to a preset publishing machine through a web interface for storage, wherein the directory where the new version jar package and the new configuration file are stored is / appcom/deploy/release date/.

S2. Obtain a cluster node server that needs to be version released, perform corresponding version detection on the jar package and configuration file in the cluster node server and the new version jar package and new configuration file, and generate a version detection report.

In at least one embodiment of the present application, the information management of the cluster node server is performed through a web interface, so in the web interface, select the cluster node server that needs to be version released, and grab the jar package and the jar package in the cluster node server. The configuration file performs corresponding version detection on the jar package and configuration file in the cluster node server and the new version jar package and the new configuration file, and generates a version detection report. The capturing of the jar package and configuration file in the cluster node server can be implemented through Python, Shell, and Ansible scripts.

Calculating the distance metric value between the jar package in the cluster node server and the jar package of the new version;

Calculating the similarity between the configuration file in the cluster node server and the new version configuration file;

Calculating the average value of the distance metric value and the similarity to obtain a version difference value;

A version detection report is generated on the web page according to the version difference value.

Wherein, sim(X,Y) represents the similarity, X represents the md5 value of the configuration file in the cluster node server, Y represents the md5 value of the new configuration file, and X _i and Y _i respectively identify the cluster node server and the new configuration file. The md5 value of the i bit, such as md5(jar)=38b8c2c1093dd0fec383a9d9ac940515, the md5 value of the first bit is 3, and the md5 value of the last bit is 5. To simplify the calculation, this application converts the characters in the md5 value into ASCII code Numerical value, for example, c is 99 after being converted into ASCII code value. The similarity generated by it ranges from -1 to 1: -1 means that the configuration file in the cluster node server and the new version configuration file point to the exact opposite direction, 1 means that their points are exactly the same, 0 It usually means that they are independent, and the value in between indicates moderate similarity and dissimilarity.

Further, in the embodiment of the present application, the average value of the distance metric value and the similarity is calculated to obtain the version difference value, and the version difference value is compared with a preset threshold value, if the version difference value is less than the preset threshold value. When the threshold value of the cluster node server and the new version cluster node server have a difference result, if the difference result value is not less than the preset threshold value, it means that the cluster node server and the new version cluster node server are not in the difference result, Thus, the version detection report is generated according to the version difference value.
