这里使用3台服务器模拟redis集群。
第一步：复制出redis到一个机器中
[root@hdp01 redis]# scp /xxx/redis-3.0.0 -r hostname01:~/apps
第二步：如果存在持久化文件，则删除 [root@hdp01 app]# rm -rf appendonly.aof dump.rdb 第三步：设置集群参数 开启集群模式： 
第五步：复制redis服务到其他机器中 [root@hdp01 redis]# scp /xxx/redis-3.0.0 -r hostname02:~/apps
[root@hdp01 redis]# scp /xxx/redis-3.0.0 -r hostname03:~/apps
第七步：启动三台机器
[root@hdp01 redis]#redis-server redis.conf(三台机器中都开启)
第九步：创建集群
[root@hdp01 redis-cluster]# ./redis-trib.rb create --replicas 1\
