Linux下应急工具

Linux下的应急工具


在Linux下,应急的查看点无非那个几个,一是看表现(宕机、高CPU、高内存、高IO、高网络通信),二看连接、三看进程、四看日志、五看文件(Linux一切皆文件),再者结合起来看。所以针对常见的应急操作自己写了两个小工具。目前支持CentOS和RedHat,其实由于基于Python,基本是跨平台,绝大部分功能支持其他发行版本的Linux甚至Windows。

工具的安装


#要求root权限
git clone https://github.com/cisp/LinuxEmergency.git
cd LinuxEmergency
sh ./install.sh
