redis集群的安装见文档

1、redis介绍与集群环境搭建

遇到的问题

1、部署Redis分布式集群时，出现了如下错误:

moguang@ubsvr13:/opt/redis-unstable/src$ ./redis-trib.rb create 192.168.1.13:6379 192.168.1.15:6380 192.168.1.40:6381

Can I set the above configuration? (type ‘yes’ to accept): yes
/usr/lib/ruby/gems/1.8/gems/redis-3.0.7/lib/redis/client.rb:97:in `call’: ERR Slot 16011 is already busy (Redis::CommandError)

经检查，这是由于上一次配置集群失败时留下的配置信息导致的。 只要把redis.conf中定义的 cluster-config-file 所在的文件删除，重新启动redis-server及运行redis-trib即可。

2、redis集群报错：(error) MOVED 11469 192.168.163.249:7002

启动集群模式(即缺少了那个”-c”):

redis-cli -c -h yourhost -p yourpost

3、redis集群创建的时候一直都在Waiting for the cluster to join…………………………..

之前我做的是把redis.conf配置文件里的bind ip选项给注释了（网上说bind 127.0.0.1也不行）

后来将绑定方式修改为:
bind 机器ip
就好了,也就是说redis集群只能绑定本机器的外网ip,其他的不能绑定
