[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.

解決方法：

1)、將需要新增的節點下aof、rdb等本地備份文件刪除；

2)、同時將新Node的集群配置文件刪除,即：刪除你redis.conf裏面cluster-config-file所在的文件；

3)、再次添加新節點如果還是報錯，則登錄新Node,./redis-cli–h x –p對數據庫進行清除：

172.168.63.201:7001> flushdb #

通過以上解決方法中的1)、2)或者3)之後再執行腳本，成功執行；
