Question

我们刚刚安装了Redis Enterprise，并在数据库上进行了一些配置。

我们在应用程序上创建了一个简单的脚本，集群命令无效，这是正确的，它是无效的：

var RedisClustr = require('redis-clustr');
var redis = new RedisClustr({
  servers: [
    {
      host: 'URL',
      port: 18611
    }
  ],
  redisOptions: {
    password: 'ourpassword'
  }
});

redis.get('KSHJDK', function(err, res) {
  console.log(res, err);
});

外壳错误：

undefined Error: couldn't get slot allocation'

      command: 'CLUSTER',
      args: [Array],
      code: 'ERR'
    }
  ]
}

我们在配置上缺少什么吗？我们不知道在群集上还是在Redis Enterprise上是否出错。

Redis Enterprise支持两种集群形式。对于常规的OSS群集，您需要一个与您使用的客户端一样的群集感知客户端。您正在使用的是面向非群集的客户端，您应该将其与常规客户端一起使用（就像您要连接到单个Redis进程一样）。
