redis-stat是一个用ruby写成的监控redis的程序，基于info命令获取信息，而不是通过monitor获取信息

一、安装ruby

yum install -y ruby ruby-devel rubygems

apt-get install rubygems  ruby1.9.1

由于国内网络原因，导致 rubygems.org 存放在 Amazon S3 上面的资源文件间歇性连接失败。所以你会与遇到 gem install rack 或 bundle install 的时候半天没有响应，所以需要修改rubygems为淘宝镜像。

二、替换rubygems

gem sources --add https://ruby.taobao.org/ --remove http://rubygems.org/

gem sources -l

三、安装redis-stat

git clone https://github.com/junegunn/redis-stat.git

gem install redis-stat

会提示

Building native extensions.  This could take a while...
Building native extensions.  This could take a while...
Building native extensions.  This could take a while...
ERROR:  Error installing redis-stat:
        redis-stat requires daemons (~> 1.1.9, runtime)

四、卸载daemons

gem uninstall daemons

gem install daemons

gem install redis-stat

装redis-stat同时会安装daemons-1.1.9，如果系统已安装daemons其他版本，需再次卸载

ERROR:  Error installing redis-stat:
        redis-stat requires daemons (~> 1.1.9, runtime)

gem uninstall daemons

Select gem to uninstall:

 1. daemons-1.1.9

 2. daemons-1.2.3

 3. All versions

> 2

Successfully uninstalled daemons-1.2.3

五、安装SystemTimer

gem install SystemTimer

然后就可以启动redis-stat了

redis-stat --verbose --server=8090 5 110.47.90.168:6379 110.160.4.71:6379

redis-stat 110.160.4.71:6379   110.47.90.168:6379  1 10
