复制代码4.在两台haroxy机器上安装配置好keealived Keealived配置 VI 192.168.1.150
Realserver 192.168.1.10 （MASTER） RealServer 192.168.1.11 （SLAVER）
分别在两台机器上配置keealived.conf文件 global_defs {

smt_server 192.168.1.3
smt_connect_timeout 30
router_id LVS_DEVEL }
vrr_instance VI_1 {

interface eth0
virtual_router_id 51
riority 100

码可以看到此机此时处于BACKU状态
5.测试
已经分配完成后可以开始做测试测试过程简单省略了 在HA的测试过程说一下
192.168.1.10宕机后192.168.1.11接管
192.168.1.10恢复后 192.168.1.11移交服务权限10
本方案经过我多次测试基本达到了架构拓扑图中的需求。这样一个简单高可用集群方案搭建完成。
