如果本地没有配置集群， 不要使用new ioredis.Cluster()方法去创建redisClient, 而是用new ioredis('6379', '127.0.0.1')去创建client[跟node-redis一样了]

 

redisCluster = [{port : 6379, host: ‘redis-server-host1’},{port : 6379, host: ‘redis-server-host2’}];if(isRedisCluster){    redisClient = new ioredis.Cluster(redisCluster); } else {     redisClient = new ioredis(6379, ‘127.0.0.1’); }
