c# - 如何使用 StackExchange.Redis 连接到哨兵集群？

Question

Stackexchange.Redis (C#) 是否支持连接到哨兵集群以获得最新版本的高可用性？我发现 redis 如此重要的特性没有正确记录或几乎没有示例，这有点奇怪。非常感谢任何帮助。

您可以通过检查 StackExchange.Redis 的测试来了解如何连接到哨兵。特别是这一个https://github.com/StackExchange/StackExchange.Redis/blob/master/tests/StackExchange.Redis.Tests/Sentinel.cs

基本上您需要查看的代码在这里:

   public Sentinel(ITestOutputHelper output) : base(output)
    {
        ConnectionLog = new StringWriter();

        Skip.IfNoConfig(nameof(TestConfig.Config.SentinelServer), TestConfig.Current.SentinelServer);
        Skip.IfNoConfig(nameof(TestConfig.Config.SentinelSeviceName), TestConfig.Current.SentinelSeviceName);

        var options = new ConfigurationOptions()
        {
            CommandMap = CommandMap.Sentinel,
            EndPoints = { { TestConfig.Current.SentinelServer, TestConfig.Current.SentinelPort } },
            AllowAdmin = true,
            TieBreaker = "",
            ServiceName = TestConfig.Current.SentinelSeviceName,
            SyncTimeout = 5000
        };
        Conn = ConnectionMultiplexer.Connect(options, ConnectionLog);
        Thread.Sleep(3000);
        Assert.True(Conn.IsConnected);
        Server = Conn.GetServer(TestConfig.Current.SentinelServer, TestConfig.Current.SentinelPort);
    }

然后在这里:

   [Fact]
    public void SentinelGetMasterAddressByNameTest()
    {
        var endpoint = Server.SentinelGetMasterAddressByName(ServiceName);
        Assert.NotNull(endpoint);
        var ipEndPoint = endpoint as IPEndPoint;
        Assert.NotNull(ipEndPoint);
        Log("{0}:{1}", ipEndPoint.Address, ipEndPoint.Port);
    }
