摘　　要：为了实现即时通信软件在主备集群环境出现断电、网络断网或者主服务器故障情况下的高可用,从架构设计、数据逻辑处理和协同交互方式3个方面提出了一种基于主备集群监控软件Kee‑palived的即时通信集群解决方案。基于Keepalived软件工作原理,在2台相同的服务器上检测服务器的运行状态,并监控软件本身的运行状态,在软件故障或服务器宕机等情况下及时进行主备服务器切换,并根据内部技术协议进行数据同步,从而实现即时通信软件高可用。最后,通过试验分析验证了设计方案的有效性。To realize high availability for instant messaging software in active-standby cluster environment in extreme conditions like power failure,network failure or malfunction of the main-server,etc.,an instant messaging cluster solution based on an active-standby cluster monitoring software named Keepalived is presented from three aspects including architecture design,data logistical processing and collaborative interaction mode.Based on the operating principle of Keepalived software,the operating states of two same servers and monitoring software self are detected.Switchover between the active server and the standby server will be carried out in in extreme conditions like software malfunction or server down,etc.,and data will be synchronized according to the interactive technical protocol.Thus,high availability for instant messaging software can be realized.Finally,the effective of the design solution is verified with experiments analysis.
