Question

我试图设置一个典型的redis哨兵配置，三台机器将运行三台redis服务器和三台redis哨兵。 redis服务器的主/从部分工作正常，但是哨兵没有工作。当我启动两个哨兵时，与主人的哨兵会检测到奴隶，但在指定的时间后将他们标记为哨兵。我在debian jessie机器上运行Redis 3.0.5 64位。

8319:X 22 Dec 14:06:17.855 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
8319:X 22 Dec 14:06:17.855 # Sentinel runid is   cdd5bbd5b84c876982dbca9d45ecc4bf8500e7a2

8319:X 22 Dec 14:07:18.862 # +sdown slave xxxxxx2:6379 xxxxxxx2    6379 @ mymaster xxxxxx0 6379

Sentinel配置文件：

daemonize yes
pidfile "/var/run/redis/redis-sentinel.pid"
logfile "/var/log/redis/redis-sentinel.log"
bind 127.0.0.1 xxxxxxx0
port 26379
sentinel monitor mymaster xxxxxxx0 6379 2
sentinel down-after-milliseconds mymaster 60000
sentinel config-epoch mymaster 0
sentinel leader-epoch mymaster 0
dir "/var/lib/redis"

当然，这些机器之间存在连接，因为奴隶工作正常：

7553:S 22 Dec 13:46:33.286 * MASTER <-> SLAVE sync started

我可以自己回答。问题是在sentinel conf中出现的第一个IP是localhost ip。它需要是绑定IP。以防它为任何人服务。

Redis sentinel将奴隶标记为
