  1. 用户透过应用服务器访问数据 1 SERVER 1 发生故障，应用停止，用户无法正常访问 2 用户通过RongcuoCLUSTER再次顺利访问数据 同时RongcuoCLUSTER将通过各种手段通知管理员 RongcuoCLUSTER接管PACKAGR 1，完成任务接管 RongcuoCLUSTER侦测到SERVER 1 故障，进入接管状态 5 4 3 多节点集群方案应用 一备多 这个方式中多个生产服务器工作在一个集群中，配置一台独立备份服务器，任何一个任务停止工作都将由备份服务器作为第一优先主机接管任务，是一种十分科学的部署方式。该部署方式有效的优化了系统结构，同时使整个集群中应用环境达到高可用。 FC SWICH 侦测到SERVER1故障 发布接管命令 Package 1 Package 2 Package 3 ACTIVE SERVER 1 ACTIVE SERVER 2 ACTIVE SERVER 3 STANDE BY RongcuoCLUSTER 每个package包含 IP地址 系统服务 系统进程 用户应用 CLIENT
