/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- redis (LoadError) from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require' from /home/maxiangqian/redis-3.2.8/src/redis-trib.rb:25
我们需要安装以下几个包：
yum -y install zlib ruby rubygems gem install redis
然后重新启动创建集群的操作：
[root@localhost redis7003]# redis-trib.rb create --replicas 1 10.103.16.34:7001 10.103.16.34:7002 10.103.16.34:7003 10.103.16.35:7001 10.103.16.35:7002 10.103.16.35:7003 >>> Creating cluster [ERR] Sorry, can't connect to node 10.103.16.34:7001
又报错了我擦。
网上各种搜资料咨询，最好还是发现不是什么版本问题，是因为我的配置文件里加了以下两行配置：
requirepass "maxiangqianredis" masterauth "maxiangqianredis"
群集是不支持认证的，把这两行注释掉就好了，然后我们在执行创建群集的命令：
[root@localhost redis7003]# redis-trib.rb create --replicas 1 10.103.16.34:7001 10.103.16.34:7002 10.103.16.34:7003 10.103.16.35:7001 10.103.16.35:7002 10.103.16.35:7003 >>> Creating cluster >>> Performing hash slots allocation on 6 nodes...

OK，已经提示成功了，我们直接选择yes就好了。

这样群集就设置成功了。
查看一下集群的状态，测试一下：
在10.103.16.34:7001创建name测试字符串，然后验证
