slave配置文件

结果可以分别进入6379和6380的redis客户端进行查看：命令为 info Replication

如果看到此处的role分别为master 和salve则说明现在已经基本配置成功了

使用哨兵模式，自动监视Master节点，当前挂掉后，自动将Slaver节点变为Master节点

       a) sentinel.conf配置文件，修改sentinel monitor host6379 127.0.0.1 6379 1，其它使用默认即可
           host6379 主机名称，随便起    主机IP 端口 1表示选举，某个slaver得到超过1票则成成为Master节点

       b) 启动sentinel： ./redis-sentinel ../sentinel.conf

 

6379 原来的Master节点重启后变成Slaver节点

另附几点声明：

1. Master可读可写，Slaver只能读，不能写
2. Master可以对应多个Slaver，但是数量越多压力越大，延迟就可能越严重
3. Master写入后立即返回，几乎同时将写入异步同步到各个Slaver，所以基本上延迟可以忽略
4. 可以通过slaveof no one命令将Slaver升级为Master（当Master挂掉时，手动将某个Slaver变为Master）
5. 可以通过sentinel哨兵模式监控Master，当Master挂掉时自动选举Slaver变为Master，其它Slaver自动重连新的Master
