Redis前哨故障切换配置问题

Question

我已经在我的环境中使用了Redis-Sentinel架构。我有3个不同的服务器。我安装并配置了redis和sentinel。基本上我有3个redis和3个前哨同时运行在3个服务器上。所有服务器都运行Centos 7，我使用的是Redis 4.0.10。没有任何网络限制。我禁用了selinux和防火墙。它看起来不错，但是当我在我的主机器上停止我的主redis进程时，我遇到了故障转移问题。

我的主机ip是: 10.0.23.242

从1: 10.0.23.243

从机2: 10.0.23.244

     [root@ibs23redistest1 redis]# redis-cli -h 10.0.23.242 -p 26379

Answer 1

两个从站都应该监控主IP，而不是他们自己的IP。

两个从属服务器的sentinel monitor redis-cluster 10.0.23.242 6379 2。

你有从站的sentinel.conf来监控他们自己的IP，因此我不认为他们会自动故障转移。
