[ERR] Node 192.168.15.102:6000 is not empty. Either the node already knows other nodes (check with CLUSTER NODES) or contains some key in database 0.

处理办法：

解决方法：

1)、停止所有redis进程，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，一般为nodes.conf；

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：

192.168.15.102:6000>  flushdb      #清空当前数据库

启动redis进程重新执行集群新建命令

./redis-trib.rb create –replicas 1 192.168.15.102:6000 192.168.15.102:6001 192.168.15.102:6002 192.168.15.102:6003 192.168.15.102:6004 192.168.15.102:6005
