给集群新增节点时提示

./redis-trib.rb add-node 192.168.1.198:7006 192.168.1.198:7000

![Center][]

解决办法：

1、先杀掉新增redis节点服务

2、删除新增节点appendonly.aof、dump.rdb、nodes.conf再执行

3、还不行再删除所有redis节点的appendonly.aof、dump.rdb、nodes.conf，再执行

4、还不行清库再执行

\[root@localhost ~\]\# cd /usr/local/redis-3.0.6/src/  
\[root@localhost src\]\# redis-cli -c -p 7000  
127.0.0.1:7000>  flushdb  
OK

我是进行到第2步就解决了

[root@localhost 7006]# cd /usr/local/redis-3.0.6/src/
    #增加主节点操作192.168.1.198:7000是任意的旧节点
    [root@localhost src]# ./redis-trib.rb add-node 192.168.1.198:7006 192.168.1.198:7000
