[ERR] Node is not empty. Either the node already knows other nodes (check with C

最近在给公司网管系统redis集群环境添加节点时候遇到一个问题,提示新增的Node不为空:


[root@node00 src]# ./redis-trib.rb add-node --slave --master-id4f6424e47a2275d2b7696bfbf8588e8c4c3a5b95 172.168.63.202:7001172.168.63.202:7000

......

[OK] All nodes agree about slotsconfiguration.

>>> Check for open slots...

>>> Check slots coverage...

[OK] All 16384 slots covered.

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 some key in database 0.

解决方法:

1)、将需要新增的节点aofrdb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;
