今天在虚拟机中的ubantu中，配置集群，报了这个错。在网上找了半天，才找到个有点关系的。

，大体意思是说配置文件没有配置好。自己只好把6个配置文件来来回回看了好几遍。结果真看出来有好几个地方没有去掉注释。

确认无误后，重启系统：

1.启动redis实例：

![Center][]

2.测试是否成功：

![Center 1][]

![Center 2][]

第三个截图里面比我一开始多了，127.0.0.1:17xxx这6个。

3.创建并启动集群:

redis-trib.rb create --replicas 1 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006 >>> Creating cluster [ERR] Node 127.0.0.1:7001 is not empty. Either the node already knows other nodes (check with CLUSTER NODES) or contains some key in database 0.

报了个错，这个错过段时间再看什么原因。

4.客户端连接集群:

看样子是可以了，继续。
