    二月 19, 2017 10:34:35 上午 redis.clients.jedis.JedisSentinelPool initSentinels
    警告: Cannot get master address from sentinel running @ 192.168.2.101:26379. Reason: redis.clients.jedis.exceptions.JedisDataException: DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command ‘CONFIG SET protected-mode no‘ from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to ‘no‘, and then restarting the server. 3) If you started the server manually just for testing, restart it with the ‘--protected-mode no‘ option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.. Trying next one.

居然报所有哨兵都down掉的错误，而我确认所有这些哨兵都正常着，百度看看，说是防火墙的问题。但是我的防火墙就没开，看来也不是这个问题。后来发现了上面打印的警告信息。

Reason: redis.clients.jedis.exceptions.JedisDataException: DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command ‘CONFIG SET protected-mode no‘ from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to ‘no‘, and then restarting the server. 3) If you started the server manually just for testing, restart it with the ‘--protected-mode no‘ option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.. Trying next one

这是因为哨兵的配置文件里的保护模式启动了。所以又因为没有绑定可以访问的ip和设置访问密码，就不允许从外部访问。

我们的哨兵明明是127的地址，应该访问127.0.0.1:26379才对啊，这是因为redis内部把127的地址转换成了192.168.2.101了，也就是你的本机的ip地址。所以访问192的地址就相当于从外部访问你的哨兵。

根据它的1，2，3，4的提示，你只要满足其中一个就行。于是我就把三个哨兵的sentinel.conf配置文件中的保护模式改为禁用就行了

# *** IMPORTANT ***
    #
    # By default Sentinel will not be reachable from interfaces different than
    # localhost, either use the ‘bind‘ directive to bind to a list of network
    # interfaces, or disable protected mode with "protected-mode no" by
    # adding it to this configuration file.
    #
    # Before doing that MAKE SURE the instance is protected from the outside
    # world via firewalling or other means.
    #
    # For example you may use one of the following:
    #
    # bind 127.0.0.1 192.168.1.1
    #
    protected-mode no

这样再访问就ok了。
