摘　　要：文章设计了一种基于国产化软硬件计算机的高可用集群软件以保证计算机系统的稳定性和可靠性。试验结果证明,当应用运行时,高可用集群软件的轮询监控程序会对应用的运行状态进行轮询监控,轮询监控的时间间隔可设置为3s,最低可设置为1秒。当应用发生故障时,轮询监控的程序检测到应用发生故障,继而触发Stonith机制实现应用的切换功能,应用本身启动时间视应用大小而定,小应用启动时间仅需10毫秒级,大应用启动时间仅需秒级。This paper designs a high availability cluster software based on domestic software and hardware computer to ensure the stability and reliability of the computer system.The test results show that when the application is running,the polling monitoring program of the highly available cluster software will poll and monitor the running state of the application.The polling monitoring time interval can be set to 3S and the minimum can be set to 1s.When an application fails,the polling monitoring program detects that the application fails,and then triggers the stoneth mechanism to realize the application switching function.The startup time of the application itself depends on the size of the application.The startup time of small applications only takes 10 milliseconds and that of large applications only takes seconds.
