Question

我有以下代码来设置 Sentinel Redis 连接。

var redisConfiguration = configuration.GetSection(redisSettingsJsonSection).Get<EightRedisConfiguration>();

    var configOptions = new ConfigurationOptions
            {
                ServiceName = redisConfiguration.ServiceName,
                TieBreaker = string.Empty,
                DefaultVersion = new Version(
                    redisConfiguration.DefaultVersionMajor,
                    redisConfiguration.DefaultVersionMinor,
                    redisConfiguration.DefaultVersionBuild),
                Password = redisConfiguration.Password,
                AbortOnConnectFail = redisConfiguration.AbortOnConnectFail,
                Ssl = redisConfiguration.Ssl,
                AllowAdmin = redisConfiguration.AllowAdmin,
                ConnectTimeout = redisConfiguration.ConnectTimeout,
                DefaultDatabase = redisConfiguration.Database
            };

            foreach (var redisHost in redisConfiguration.Hosts)
            {
                configOptions.EndPoints.Add(redisHost.Host, redisHost.Port);
            }

            configOptions.CommandMap = redisConfiguration.IsSentinelCluster ? CommandMap.Sentinel : CommandMap.Default;

            services.AddSingleton(_ =>
                    ConnectionMultiplexer
                        .Connect(configOptions, logTextWriter)
                        .GetSentinelMasterConnection(configOptions));

我收到以下异常。

配置如下

"DefaultVersionMajor": 4,
    "DefaultVersionMinor": 0,
    "DefaultVersionBuild": 11,
    "ServiceName": "eight-sentinel",
    "IsSentinelCluster": true,
    "Password": "AWESOME_PASSWORD",
    "AllowAdmin": true,
    "Ssl": false,
    "ConnectTimeout": 3000,
    "ConnectRetry": 2,
    "Database": 0,
    "Hosts": [
      {
        "Host": "redis-1.com",
        "Port": 26379
      },
      {
        "Host": "redis-2.com",
        "Port": 26379
      },
      {
        "Host": "redis-3.com",
        "Port": 26379
      }
    ]

我对这个问题有点迷茫，不确定它背后的信息，我可以使用 Redis 桌面管理器客户端连接到哨兵集群，只需添加第一个实例。

我也有类似的问题，经过一些研究，我意识到他们在库中有一些问题，似乎使用 ConfigurationOptions.

有问题

正如它所建议的那样here ，如果您通过连接字符串创建连接，它会起作用

using(var connection=new ConnectionMultiplexer.Connect("10.1.3.11:26379,10.1.3.12:26379,10.1.3.13:26379,serviceName=redis-primary,AllowAdmin=true"))
{
// do stuff
}

您必须在连接字符串中指定 ServiceName 才能连接到 Sentinel。

他们引入了一种新方法 SentinelConnect，该方法不适用于相同的连接字符串！

如果您使用的 StackExchange.Redis.Extensions.Core 库没有带连接字符串的构造函数，您应该创建一个 RedisConfiguration 的空实例，并在 ConnectionPoolManager 实现中通过 ConnectionString 进行连接。
