原因是Redis.xml,配置文件没有修改ip地址；

后来在Linux启动集群虚拟机时报错：

[ERR] Node 10.0.0.133:7001 is not empty. Either the node already 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
