哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈。终于他妈的成功了！！！！
Redis-trib会提示你做了什么配置, 输入yes接受. 集群就被配置和加入了, 意思是, 实例会经过互相交流后启动。
测试集群的状态：

可以看到有3个主节点，3个从节点。每个节点都是成功的连接状态。
3个主节点［M］是：

7000 (3707debcbe7be66d4a1968eaf3a5ffaf4308efa4)
7001 (cb5c04b6160c3b7e18cad5d49d8e2987b27e0d6c)
7002 (dfa0754c7854a874a6ebd2613b86140ad97701fc)

3个从节点［S］是：

7003 (d2237fdcfbba672de766b913d1186cebcb6e1761)->7000
7004 (4b4aef8b48c427a3c903518339d53b6447c58b93)->7001
7005 (30858dbf483b61b9838d5c1f853a60beaa4e7afd) ->7002
