启动各个节点，三台服务器

redis-server /home/redis_cluster/7000/redis.conf
redis-server /home/redis_cluster/7001/redis.conf

创建集群，只在redis-trib.rb执行端安装以下程序

redis-3.2.2.gem文件拷贝到84服务器，以下命令只在84上执行。注意这里的ruby的redis驱动版本不用和redis服务端版本一致，ruby的redis驱动版本是redis-3.2.2，redis服务端的版本是redis-4.0.2
yum install ruby ruby-devel rubygems rpm-build
gem install redis-3.2.2.gem
./redis-trib.rb create --replicas 1 10.24.70.81:7000 10.24.70.81:7001 10.24.70.82:7000 10.24.70.82:7001 10.24.70.84:7000 10.24.70.84:7001
