Redis主从加Sentinel模式部署  
总体部署  
一主二从三哨兵  
ip地址分配分别为  
主 127.0.0.1:6379  
从 127.0.0.1:6389  
从 127.0.0.1:6399  
哨兵 127.0.0.1:26379  
哨兵 127.0.0.1:26389  
哨兵 127.0.0.1:26399  
   
一主二从的配置文件 redis.conf设置  
主的保持默认的不变  
二个从的分别打开配置文件  
找到设置端口的地方  
分别设置为 6389 和6399  
\# Accept connections on the specified port, default is 6379 (IANA \#815344).  
\# If port 0 is specified Redis will not listen on a TCP socket.  
port 6389  
\# Accept connections on the specified port, default is 6379 (IANA \#815344).  
\# If port 0 is specified Redis will not listen on a TCP socket.  
port 6399  
然后都在  
\# slaveof <masterip> <masterport>  
一行的下面增加  
slaveof 127.0.0.1 6379  
这样主从的配置就ok了  
   
   
三个哨兵的sentinel.conf配置  
分别打开sentinel.conf配置文件  
修改他们的端口为  
 26379 26389 26399  
   
sentinel monitor mymaster 127.0.0.1 6379 2  
配置中的这一行表示 我们要监视的主的ip和端口，mymaster是主的名称，因为我们的主是127.0.0.1:6379,所以三个哨兵中的这个地方都不用修改。  
   
然后所有的配置就ok了，本地测试环境貌似需要改动的地方不多。

验证  
新开一个命令行窗口进入redis的src目录，用redis-cli工具登录其中一个哨兵  
./redis-cli -p 26379  
连接成功后运行如下命令  
sentinel master mymaster
