haproxy配置监控redis主备切换

环境前提：

    redis sentinel配置，三台主机，且配置运行良好

    

配置文件中添加：

frontend ft_redis

 bind 0.0.0.0:6379 name redis

 default_backend bk_redis

backend bk_redis

 option tcp-check

 tcp-check connect

 tcp-check send PING\r\n

 tcp-check expect string +PONG

 tcp-check send info\ replication\r\n

 tcp-check expect string role:master

 tcp-check send QUIT\r\n

 tcp-check expect string +OK

 server R1 10.118.36.10:6379 check inter 1s

 server R2 10.118.36.74:6379 check inter 1s

 server R3 10.118.5.161:6379 check inter 1s

当结果如下所示，则表示成功，那么试着切换redis的master和slave吧
