创建Redis集群命令如下：
./redis-trib.rb create --replicas 1 192.168.179.128:7001 192.168.179.128:7002 192.168.179.128:7003 192.168.179.128:7004 192.168.179.128:7005 192.168.179.128:7006
由于手贱未正常操作，导致在后面查看集群是否创建成功时（cluster nodes），只显示了一个master连接。

解决办法：
重新创建集群。如下步选择yes十分关键，创建时必须Assign a different config epoch to each node
Can I set the above configuration? (type 'yes' to accept): yes
>>> Nodes configuration updated
>>> Assign a different config epoch to each node
>>> Sending CLUSTER MEET messages to join the cluster
