install LAMP

　　sudo apt-get install lamp-server^

　　install zabbix

　　if install via cmd like：

　　sudo apt-get install zabbix-server-mysql zabbix-frontend-php

　　when zabbix installed with version 1.8

　　so， I manually installed zabbix 2.2.1：

　　install zabbix 2.2.1 with zabbix-frontend-php 2.2.1-1+precise all.deb and zabbix-server-mysql 2.2.1-1+precise amd64.deb

　　if you already installed older version zabbix ， it will remind you whether reinstall the database or not

　　open zabbix http：//localhost/zabbix ，it will  show you some pre-requirements where need most careful

　　p.s. if the requirement relate to php，need to change the php.ini， it locate to /etc/php5/apache2 and /etc/php5/cli

　　some problem left：

　　1. install zabbix from soure code failed…
