报错信息：[ERR] Node 192.168.245.111:6379 is not empty. Either the node already knows other nodes (check with CLUSTER NODES) or contains some key in database 0.

背景：第二天启动redis集群就报错（第一天正常工作，然后关机）

原因: 可能是非正常关闭集群导致

1-数据清空 flushdb命令清除所有节点中（我的是6个节点，3主3从）的数据

从机不能清空（从机只能读数据），只需要清空主机数据（3个主机）

2-关闭redis-server, kill -p 进程号命令

3-删除 drumpXXX.rdb nodes-XXX.conf文件 rm -rf 命令

4-启动redis-server

[root@redis111 bin]# redis-server /etc/redis/redis6379.conf
[root@redis111 bin]# redis-server /etc/redis/redis6380.conf
[root@redis111 bin]# redis-server /etc/redis/redis6381.conf
[root@redis111 bin]# redis-server /etc/redis/redis6389.conf
[root@redis111 bin]# redis-server /etc/redis/redis6390.conf
[root@redis111 bin]# redis-server /etc/redis/redis6391.conf

nodes-XXX.conf文件生成正常

5-以集群方式启动redis

合体 cd /opt/module/redis-6.2.6/src

redis-cli --cluster create --cluster-replicas 1 192.168.245.111:6379 192.168.245.111:6380 192.168.245.111:6381 192.168.245.111:6389 192.168.245.111:6390 192.168.245.111:6391
