哨兵机制；
1，redis下载：下载的地址是：https://pan.baidu.com/s/1dEMCa9z
2，复制6个，三个redis，三个sentinel
D:Redis-Sentinel>ls -al total 5140 drwxr-xr-x 1 stono 197121 0 May 7 18:40 . drwxr-xr-x 1 stono 197121 0 May 7 18:39 .. drwxr-xr-x 1 stono 197121 0 May 7 19:00 Redis-6379 drwxr-xr-x 1 stono 197121 0 May 7 19:00 Redis-6380 drwxr-xr-x 1 stono 197121 0 May 7 19:00 Redis-6381 -rw-r--r-- 1 stono 197121 5224077 May 7 16:59 Redis-x64-3.2.100.zip drwxr-xr-x 1 stono 197121 0 May 7 18:49 Sentinel-26379 drwxr-xr-x 1 stono 197121 0 May 7 18:54 Sentinel-26380 drwxr-xr-x 1 stono 197121 0 May 7 18:54 Sentinel-26381
3，修改redis中的config
=====6379文件====
port 6379 requirepass QazEdc123456! masterauth QazEdc123456!
6379文件里面也加上masterauth吧，感觉可能会有用，当主节点的master状态变动之后；
6380、6381文件一样，注意修改端口；
还需要加上：
slaveof 127.0.0.1 6379
=====26379sentinel.conf文件=====
port 26379 #master-0 sentinel monitor master-0 127.0.0.1 6379 2 sentinel down-after-milliseconds master-0 5000 sentinel auth-pass master-0 QazEdc123456! sentinel config-epoch master-0 0
2380、26381文件一样，注意修改端口
sentinel启动后会增加一些内容：
sentinel myid f033f87745f732e6e9071809a3b3cf289c4a5b78 # Generated by CONFIG REWRITE dir "D:\Redis-Sentinel\Sentinel-26379" sentinel leader-epoch master-0 0 sentinel known-slave master-0 127.0.0.1 6380 sentinel known-slave master-0 127.0.0.1 6381 sentinel known-sentinel master-0 127.0.0.1 26381 509a7fac5ec41e058cd244aa75680948454c662d sentinel known-sentinel master-0 127.0.0.1 26380 7a1892de605d560c29cd9159d6760148a3fff9df sentinel current-epoch 0
4，启动
redis启动：
redis-server.exe redis.windows.conf
sentinel启动：
redis-server.exe sentinel.conf --sentinel
