[ERR] Node xxxxx is not empty. Either the node already knows other nodes (check with CLUSTER NODES)-蒲公英云

[ERR] Node xxxxx is not empty. Either the node already knows other nodes (check with CLUSTER NODES)

问题示例：

执行创建redis集群命令时，

# 我这里ip都是172.17.0.1是因为我这里的redis节点都是docker容器，每个容器都已经映射到了主机172.17.0.1的不同端口
redis-cli --cluster create 172.17.0.1:6391 172.17.0.1:6392 172.17.0.1:6393 172.17.0.1:6394 172.17.0.1:6395 172.17.0.1:6396 --cluster-replicas 1

报错：

>> Creating cluster
 [ERR] Node 172.17.0.1:6379 is not empty. Either the node already knows other nodes (check with CLUSTER NODES) or contains some key in database 0.

解决办法：

1.停止所有redis进程（我集群节点是 docker-compose 创建的，所以只需要docker-compose down即可）
2.将每个节点对应的.aof，.rdb .conf 文件删除，（注意：启动配置文件也是.conf后缀，请不要误删），具体文件对应位置需要查看每一个redis节点的启动配置文件的配置项，如我的集群配置文件：

dbfilename dump-6379.rdb
appendfilename “appendonly_6379.aof”
cluster-config-file “cluster/nodes-6379.conf”
3.启动redis进程（.我集群节点是 docker-compose 创建的，所以只需要docker-compose -d up即可），并重新创建集群

redis-cli —cluster create 172.17.0.1:6391 172.17.0.1:6392 172.17.0.1:6393 172.17.0.1:6394 172.17.0.1:6395 172.17.0.1:6396 —cluster-replicas 1
