启动服务
打开6个CMD命令行工具,切换到C:
\redis-64.3.0.503目录下，分别输入
Redis-server.exeredis.7001.conf
Redis-server.exeredis.7002.conf
Redis-server.exeredis.7003.conf
Redis-server.exeredis.7004.conf
Redis-server.exeredis.7005.conf
Redis-server.exeredis.7006.conf
启动成功后界面如下
3.Ruby安装
下载地址：
安装界面如下所示
安装完成后，打开命令输入ruby–v命令检查是否安装成功
4.安装redis的ruby运行库
打开命令行输入geminstallredis命令
5.下载redis-trib.rb脚本文件
redis-trib.rb文件是运行redis集群的脚本库,文件内容如下,可将下面的文件内容拷贝到记事本中另存为redis-trib.rb文件
然后将redis-trib.rb拷贝到C:
\redis-64.3.0.503目录下
