对于redis-sentinel我在之前的文章中已经说过，它是一个仲裁者，当主master挂了后，它将在所有slave服务器中进行选举，选举的原则当然可以看它的官方文章，这与我们使用者没有什么关系，而对于sentinel来说，它在进行主从切换时，会触发相关事件，这是和我们开发人员有关系的，如当+switch-master事件被触发时，说明当前Sentinal已经完成了一次主从的切换，并所有服务已经正常运转了。

下面是我这几天作的测试，对于Twemproxy代理和Sentinal哨兵都已经成功使用stackExchange.redis进行了连接，并正常访问了，当然Sentinel只公开了几个redis命令，这个大家要清梦，不明白的可以看我的这篇文章《Redis集群~windows下搭建Sentinel环境及它对主从模式的实际意义》。

连接普通的redis服务器

  ConnectionMultiplexer conn = ConnectionMultiplexer.Connect("127.0.0.1:6379");
  ConfigurationOptions option = new ConfigurationOptions();

  option.EndPoints.Add("127.0.0.1", );

  ConnectionMultiplexer conn = ConnectionMultiplexer.Connect(option);

连接TW代理服务器

    ConfigurationOptions twOption = new ConfigurationOptions();

    twOption.EndPoints.Add("127.0.0.1", );

    twOption.EndPoints.Add("127.0.0.1", );

    twOption.Proxy = Proxy.Twemproxy;//代理的类型

    ConnectionMultiplexer conn = ConnectionMultiplexer.Connect(twOption);

连接Sentinal仲裁哨兵服务器

           //连接sentinel服务器

            ConfigurationOptions sentinelConfig = new ConfigurationOptions();

            sentinelConfig.ServiceName = "master1";

            sentinelConfig.EndPoints.Add("192.168.2.3", );

            sentinelConfig.EndPoints.Add("192.168.2.3", );

            sentinelConfig.TieBreaker = "";//这行在sentinel模式必须加上

            sentinelConfig.CommandMap = CommandMap.Sentinel;

            // Need Version 3.0 for the INFO command?

            sentinelConfig.DefaultVersion = new Version(, );

            ConnectionMultiplexer conn = ConnectionMultiplexer.Connect(sentinelConfig);

有了上面的代码后，我们可以成功的连接一个sentinel服务器，对这个连接的实际意义在于：当一个主从进行切换后，如果它外层有Twemproxy代理，我们可以在这个时机（+switch-master事件)通知你的Twemproxy代理服务器，并更新它的配置文件里的master服务器的地址，然后从起你的Twemproxy服务，这样你的主从切换才算真正完成。

对于Twemproxy-sentinal-master/slave主从切换实现图

我们可以使用.netcore开发一个跨平台的程序，将它放在linux的tw代理服务器上，使用dotnet run去运行它，然后当收到由sentinel发来的+switch-master事件时，将更新tw配置文件并从起它的服务。
