[redis] Node is not empty. Either the node already knows other nodes

Connecting to node 172.168.63.202:7001: OK

[ERR] Node 172.168.63.202:7001 is not empty. Either the nodealready knows other nodes (check with CLUSTER NODES) or contains somekey in database 0.

解决方法：

1)、将需要新增的节点下aof、rdb等本地备份文件删除；

2)、同时将新Node的集群配置文件删除,即：删除你redis.conf里面cluster-config-file所在的文件；

重新执行集群创建命令,即可。
