通过 NestJS 缓存模块的 Redis ElastiCache 连接错误

Question

我正在尝试将 CacheModule 连接到 AWS ElastiCache 上的 Redis 服务器，但没有成功。

我通过 EC2 本身内的 redis-cli 建立了连接，它工作正常，但 NestJS 没有连接。

CacheModule.register<RedisClientOptions>({
      isGlobal: true,
      store: redisStore,
      socket: {
        host: 'master.my-server.use1.cache.amazonaws.com',
        port: 6379,
        tls: true,
      },
      password: 'my-password',
    }),

PM2/控制台错误：

PM2        |       throw er; // Unhandled 'error' event

文档中有错误。 该文档考虑到 cache-manager-redis-store 支持 redis v4，因此导致读者相信他们在未读取时设置了主机和端口： https ://github.com/nestjs/docs.nestjs .com/pull/2333
