redis-stat是一个用Ruby编写的简单的Redis监控工具。

它基于Redis的INFO命令，因此与基于MONITOR命令的其他监视工具不同，它通常不会影响Redis实例的性能。 redis-stat允许您监视Redis单实例和集群。
*或者使用终端的vmstat-like输出
*或者通过嵌入式Web服务器提供的仪表板页面

0，安装redis 参考此篇文章:centos7 安装redis

1，安装ruby gem

yum install ruby ruby-devel rubygem

2，升级ruby到2.4参考此篇文章:升级ruby到2.4 版本

3，安装ruby和redis之间通信工具

#更换gem源，使用国内镜像源下载更快
gem source -a https://ruby.taobao.org/ #添加淘宝源
gem source -r http://rubygems.org/ #删除境外源
