一：寫bash腳本時候經常用到的顏色代碼
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：自動化部署簡介
由於服務器數量的不斷增加，面對數以千計的需要做Nagios 監控的客戶端，自動化部署就會被提上日程了,自動化部署最簡單的是把安裝時的命令通過腳本組合在一起，再加上一些成功與否的判斷
