1 #TwRedis(同一个Sentinel可以同时监听多个Master服务器) 2 #设置要监听的服务器名称 IP和端口,最后一个2表示至少要两个 Sentinel服务器判定 Master失效 才会执行自动故障迁移 3 sentinel monitor TwRedis 127.0.0.1 6001 2  4 #指定了Sentinel认为Redis实例已经失效所需的毫秒数 5 sentinel down-after-milliseconds TwRedis 10000 7 #指定了在执行故障转移时，最多可以有多少个从Redis实例在同步新的主实例，
 8 #在从Redis实例较多的情况下这个数字越小，同步的时间越长，完成故障转移所需的时间就越长 8 sentinel config-epoch TwRedis 1 9 #指定Sentinel运行的端口10 port 5001
