一：写bash脚本时候经常用到的颜色代码

COLOR_SUCCESS=$（echo -en "[url=file://\\033[1;32m]\\033[1;32m[/url]" ）COLOR_FAILURE=$(echo -en "[url=file://\\033[1;31m]\\033[1;31m[/url]" )COLOR_WARNING=$(echo -en "[url=file://\\033[1;33m]\\033[1;33m[/url]")COLOR_NORMAL=$(echo -en "[url=file://\\033[0;39m]\\033[0;39m[/url]")

二：自动化部署简介

由于服务器数量的不断增加，面对数以千计的需要做Nagios 监控的客户端，自动化部署就会被提上日程了,自动化部署最简单的是把安装时的命令通过脚本组合在一起，再加上一些成功与否的判断
