Abstract

The invention provides a software package management method and system for a data center cluster system. The data center cluster system comprises a central server and a plurality of server nodes. Themethod comprises the steps of receiving a software operation and / or running command sent by a server node, wherein the command comprises software name and version; creating at least one target container image in the central server, wherein the at least one target container image packages software of at least one version and all contained dependent items of the software; and setting an environmental variable for the server node and mounting the target container image, thereby enabling the server node to operate and / or run the software. By utilizing self-contained, self-organization and securityisolation characteristics of a container, for a software isomorphism characteristic of a data center cluster, an out-band online software package management mechanism is realized, so that the controlmanagement problems of multi-software multi-version, sharing and isolation, security and credibility, online updating and the like in the data center cluster system are solved.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically, to a software package management method and system for a data center cluster system. Background technique [0002] At present, each distribution version of the Linux system has its own software package management system. These software package management systems can facilitate software management for users, such as deb, yum / rpm, zypper / yast / rpm, and these management systems are based on berkeley db (referred to as BDB ) database to store software package information, it is necessary to maintain a database (Berkeley DB) on each server node. Due to various reasons such as installation process, maintenance personnel, maintenance methods, and maintenance tools, it is difficult to guarantee thousands or even several Tens of thousands of database copies are completely consistent, which leads to inconsistencies in the behavior of applications running on different nodes d...
