node.js - 使用 node.js ioredis 连接到 Azure Redis 集群不起作用

Question

我一直在尝试使用 ioredis 连接到 Azure 中的 Redis 三 Node 集群.

当我使用 Redis.Cluster 构造函数进行连接时:

new Redis.Cluster(['host.redis.cache.windows.net', 6380], {
    scaleReads: 'all',
    slotsRefreshTimeout: 2000,
    redisOptions: {
        password: 'some-secret',
        tls: true as any
    },
});

我得到的错误是:

2020-06-04T13:05:41.788Z ioredis:redis status[127.0.0.1:6380 (ioredisClusterRefresher)]: [empty] -> wait

当我使用非集群 Redis 连接进行连接时:

new Redis(6380, 'host.redis.cache.windows.net', { password: 'some-secret' });

我得到的错误是:

020-06-04T15:04:08.609Z ioredis:redis status[10.211.x.x:6380]: connecting -> connect
2020-06-04T15:04:08.614Z ioredis:redis write command[10.211.x.x:6380]: 0 -> auth([ 'some-secret' ])
2020-06-04T15:04:08.616Z ioredis:redis write command[10.211.x.x:6380]: 0 -> info([])
2020-06-04T15:05:16.114Z ioredis:connection error: Error: read ECONNRESET

    at TCP.onStreamRead (internal/stream_base_commons.js:111:27) errno: 'ECONNRESET', code: 'ECONNRESET', syscall: 'read' }

正如您所看到的，它在端口 6380 上使用 TLS。Azure 为我提供了一个主机+端口组合和两个不同的访问 key (主要/次要) - 我觉得这很奇怪，我应该使用哪个访问 key ？另外，我不确定是否应该以集群模式进行连接，但我更愿意获得集群的好处。当我这样做时，它似乎试图在 127.0.0.1:6380 处找到插槽，这可能不正确。

在 Azure 中 quickstart他们使用node_redis连接:

var redis = require("redis");

// Add your cache name and access key.
var client = redis.createClient(6380, process.env.REDISCACHEHOSTNAME,
    {auth_pass: process.env.REDISCACHEKEY, tls: {servername: process.env.REDISCACHEHOSTNAME}});

我希望这里有人遇到同样的问题并解决它。

谢谢!

好的，我已成功使用非 tls 连接连接到 Azure Redis 集群:

new Redis.Cluster(['host.redis.cache.windows.net', 3679], {
    scaleReads: 'all',
    slotsRefreshTimeout: 2000,
    redisOptions: {
      password: 'some-secret',
    },
})

由于某种原因，无法在启用 TLS 的情况下连接到 6380。
