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 port0 isspecified Redis will not listen on a TCP socket.
port6389
# Accept connections on the specified port, default is 6379 (IANA #815344).
# If port0 isspecified Redis will not listen on a TCP socket.
port6399
然后都在
# slaveof
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。

哨兵2和哨兵3启动过程相同
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
