StackExchange.Redis ConnectionMultiplexer.Connect()间歇工作

Question

我StackExchange.Redis用来与3个不同的Redis实例通信:1个在同一个子网上,2个在远程.这是我的配置代码:

var configurationOptions = new ConfigurationOptions
{
    EndPoints =
    {
        { host, port }
    },
    KeepAlive = 180,
    Password = password,
    DefaultVersion = new Version("2.8.5"),
    // Needed for cache clear
    AllowAdmin = true
};

var connectionMultiplexer = ConnectionMultiplexer.Connect(configurationOptions );

最后一行大约70%的时间抛出连接异常:

无法连接到redis服务器; 要创建断开连接的多路复用器,请禁用AbortOnConnectFail

为什么这是间歇性的和/或我做错了什么？当我在命令提示符下ping Redis服务器时,丢包率为0%,响应时间<1 ms.网络稳定.

谢谢!

以下是失败时日志输出的内容:

Answer 1

通过在连接到Redis时为客户端设置ConnectTimeout,我能够解决它.这是我的代码

 ConnectionMultiplexer connection = 
        ConnectionMultiplexer.Connect("endpoint,password=password,ConnectTimeout=10000");

这似乎是一个常见的问题:https://github.com/StackExchange/StackExchange.Redis/issues/42

我刚刚下载了新版本,并没有再次看到问题.然而.

Answer 3

您收到的错误通常表明您尚未abortConnect=false在连接字符串中设置。默认值为abortConnect，true这使得StackExchange.Redis在某些情况下不会自动重新连接到服务器。我们强烈建议您设置abortConnect=false连接字符串，以便在发生网络故障时 Redis 能够在后台自动重新连接。

所以我的init()看起来像这样

ConfigurationOptions co = new ConfigurationOptions()
{
    SyncTimeout = 500000,
    EndPoints =
    {
        {url,portNumber }
    },
    AbortOnConnectFail = false // this prevents that error
};

seClient = ConnectionMultiplexer.Connect(co);

谢谢
