Question

我在StackExhange.Redis中有一个关于redis sentinel的问题。

Redis版本：3.0.504

StackExchange.Redis版本：1.2.1

我已经在我的电脑（Windows 7）中配置了redis sentinel，如果我关闭了master，

奴隶之一将升级为主人，一切运作良好。但我不知道如何在客户端代码中做到这一点，

我的代码如下：

public class RedisConnectiontHelper
{
    private static readonly Lazy<ConnectionMultiplexer> LazyConnection;

    static RedisConnectiontHelper()
    {

        ConfigurationOptions config = new ConfigurationOptions
        {
            EndPoints =
            {
                {"127.0.0.1",6379}, // master
                {"127.0.0.1",6380}, // slave
                {"127.0.0.1",6381}  // slave
            },
            ConnectRetry = 15000,
            ConnectTimeout = 15000,
            SyncTimeout = 15000
        };
        LazyConnection = new Lazy<ConnectionMultiplexer>(() => ConnectionMultiplexer.Connect(config));
    }

    public static ConnectionMultiplexer Connection
    {
        get { return LazyConnection.Value; }
    }
}

public class RedisCacheManager
{
    public readonly IDatabase RedisDatabase = RedisConnectiontHelper.Connection.GetDatabase();

    private static readonly Lazy<RedisCacheManager> CacheManager = new Lazy<RedisCacheManager>(() => new RedisCacheManager());

    static RedisCacheManager() { }

    public static RedisCacheManager RedisCacheManagerInstance
    {
        get { return CacheManager.Value; }
    }

    protected byte[] Serialize(object item)
    {
        var jsonString = JsonConvert.SerializeObject(item);
        return Encoding.UTF8.GetBytes(jsonString);
    }
    protected T Deserialize<T>(byte[] serializedObject)
    {
        if (serializedObject == null)
            return default(T);

        var jsonString = Encoding.UTF8.GetString(serializedObject);
        return JsonConvert.DeserializeObject<T>(jsonString);
    }

    public virtual void Set(string key, object data, int cacheTime)
    {
        if (data == null)
            return;

        var entryBytes = Serialize(data);
        var expiresIn = TimeSpan.FromMinutes(cacheTime);

        RedisDatabase.StringSet(key, entryBytes, expiresIn);
    }
}

测试代码：

 var redisCacheManager = RedisCacheManager.RedisCacheManagerInstance;
        for (int i = 0; i < 50000; i++)
        {
            string key = "test-" + i;

            var model = new RedisSampleModel
            {
                Key = key,
                Name = Guid.NewGuid().ToString()
            };

            redisCacheManager.Set(key, JsonConvert.SerializeObject(model), 60);
        }

在程序仍在执行时，我关闭主服务器，然后在方法“RedisDatabase.StringSet（key，entryBytes，expiresIn）;”中抛出错误“远程主机强制关闭连接”;

那我该如何解决这个问题？

有没有办法完成slave自动升级到master并且没有使用StackExchange.Redis的错误？
