Mocha BSM在Linux系统上实现高可用案例

    25年在马来西亚某大型IDC机房建设项目，客户要求采购的网络运维监控软件，必须实现双机热备，30秒能完成切换。

    因为用户没有单独的操作系统及商业化热备软件预算，厂家交付工程师和集成商项目组论证后，在两台Dell Poweredge R450服务器上，采用较为成熟的开源CentOS+Keepalived方案。相对于常见的如ERP，OA等业务系统，运维管理系统的双机热备设计更为复杂，除了底层Mysql数据库同步，操作系统虚拟IP的接管，还有数据采集引擎的快速启动和初始化，切换过程无告警误报的要求。

    项目组在国内搭建环境多次测试，系统调优，确定在主服务器关机、重启或网络掉线20秒内，备机完成系统级切换，用户可登录Portal。60秒内全部数据刷新。切换过程中无误报。

    25年春节前，和工程师远赴几千公里的现场，2天内完成交付，测试通过，一切顺利！OLG

现场机房远景
