部署到服务器后无法连接到Azure Redis缓存

问题描述

some-prod.redis.cache.windows.net上的UnableToConnect：6380 /交互式，正在初始化/未启动，最后一个：无，来源：BeginConnectAsync，未完成：0，最后一次读取：5s之前，最后一次写入：5s之前，keep-alive：60s，状态：Connecting，mgr：10（共10）可用，last-heartbeat：never，global：5s前，v：2.1.58.34321 我正在尝试建立类似的连接

私有静态Lazy azureRedisCacheConnection = new Lazy（（）=> { 返回ConnectionMultiplexer.Connect（AzureRedisCacheConfiguration.Instance.ConnectionString）; }）;

    public static ConnectionMultiplexer RedisCacheConnection
    {
        get
        {
            return azureRedisCacheConnection.Value;
        }
    }

解决方法

我认为也许connectionStrings应该附加,allowAdmin=true。那只是我的猜测。

常规，您应该在防火墙中添加规则。

故障排除。

您可以使用调试模型来部署Web应用程序，并可以使用远程调试来捕获错误。

您可以download my sample code in github。我的示例代码已经过测试，您可以尝试。
