Redis3.0.3集群安装
cd /home/redis#把软件下载到/home/redis/software目录下，将应用安装到/home/redis目录下。mkdir cluster #创建cluster存放集群软件
cd cluser
mkdir 7000 7001 7002 7003 7004 7005 #创建6个目录，里面分别部署一个redis，三个master，三个slave
cp /home/redis/software/redis.conf ./ #复制一份配置文件
cp /home/redis/software/src/redis-trib.rb ./ #复制集群启动脚本
