一：redmon的安装和使用
1:安装rvm，rvm是ruby version manager的缩写，ruby语言是鬼子弄出来的，虽然不是程序员，我也一直不待见，真心觉得难用！
#bash > ~/.bash_profile
2:查看可用的ruby版本
1. # /usr/local/rvm/bin/rvm list known
3：通过rvm安装ruby
1. # /usr/local/rvm/bin/rvm install 1.9.2
2. # /usr/local/rvm/bin/rvm alias create default ruby-1.9.2-p320
3. # /usr/local/rvm/bin/rvm list
4. rubies
5.
6. =* ruby-1.9.2-p320 [ x86_64 ]
7.
8. >
9. # =* - current && default
10. # * - default
11.
12. # ruby -v
13. ruby 1.9.2p320 (2012-04-20 revision 35421) [x86_64-linux]
4:通过gem安装bundler
1. # gem install bundler
5：通过git获取redmon源代码并安装

6：web接口情况，使用上存在无法添加对多个redis实例的监控
redmon监控安装参考下列文章，在此感谢作者分享！

二：redis-live的安装和使用，同redmon相比，添加多个redis实例监控显得非常容易！而且实时性强，大赞！

1、场景需求 根据我们对keepalived的了解，我们知道它基于VRRP协议不但实现了高可用性的功能，而且还实现了基于脚本文件实现了状态监测的功能，而这个功能使用的场景非常多。 拓展开来，只要我们掌握这个状态监测的方法，我们就可以对keepalived管理的…
