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

1. 主 127.0.0.1:6379
2. 从 127.0.0.1:6389
3. 从 127.0.0.1:6399
4. 哨兵 127.0.0.1:26379
5. 哨兵 127.0.0.1:26389
6. 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

结果如下
