[ERR] Node 172.168.63.202:7001 is not empty. Either the nodealready knows other nodes (check with CLUSTER NODES) or contains some key 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；

3)、再次添加新节点如果还是报错，则登录新Node,./redis-cli–h x –p对数据库进行清除：

172.168.63.201:7001>  flushdb      #清空当前数据库

通过以上解决方法中的1)、2)或者3)之后再执行脚本，成功执行；
