call'：ERR MEET 中的 IP 地址无效（Redis::CommandError）Redis

Question

当我第一次执行 redis cluster 命令时，出现以下错误

>>> Performing hash slots allocation on 2 nodes...
M: a644f0c711c6a7a455f4154682beb0866df0c1e5 10.1.0.164:1234
   slots:0-8191 (8192 slots) master
M: 3d057397fbafc5a29a5c9aacffec70b3b356cbed 10.1.2.68:1112
slots:8192-16383 (8192 slots) master
Can I set the above configuration? (type 'yes' to accept): yes
>>> Nodes configuration updated
>>> Sending CLUSTER MEET messages to join the cluster
/Library/Ruby/Gems/1.8/gems/redis-3.0.4/lib/redis/client.rb:85:in `call': ERR Invalid      IP address in MEET (Redis::CommandError)

如果我第二次执行相同的命令，错误将更改为以下

>>> Performing hash slots allocation on 2 nodes...
M: b19f4a4e3fd69e905897937cb694c62ceaf47643 127.0.0.1:1112

请帮我解决这两个问题。

如果有Redis集群配置傻瓜教程请分享给我。

    same issue.
