zabbix 一键安装，前提是mysql已安装好，且已设好密码，已在centos 6.5上做过测试

#!/bin/bash

#zabbix 一键安装
#数据库用户名
DBUSER='root'
#数据库用户密码
DBPASS='root'
#本地地址
DBHOST='localhost'
#zabbix 下载的版本
ZBX_VER='2.4.3'


###检查返回值 
function checkReturn {
  if [ $1 -ne 0 ]; then
     echo "fail: $2"
     echo "$3"
     exit
  else
     echo "pass: $2"
  fi
  sleep 3
}

###安装的前提条件
###只个版本只可在centos或redhat 6.0上安装
###前提需要先安装mysql

=== RUN AT YOUR OWN RISK ===

DO NOT RUN ON EXISTING INSTALLATIONS, YOU *WILL* LOSE DATA

This script:
 * Installs Zabbix 2.2.x on CentOS / Red Hat 6
 * Drops an existing database
 * Does not install MySQL; to install type "yum install mysql-server"
 * Assums a vanilla OS install, though it tries to work around it
 * Does not install zabbix packages, it uses source from zabbix.com
 * Disables firewall
 * Disables SELinux
