zabbix server&agent端自动安装脚本-纯编译版

15,983 次

摘要

本脚本实现了一键配置zabbix的server端或者agent端的环境，由于MariaDB采取了编译安装的方法，所以在测试的时候系统内存不建议小余4GB。
当然你也可以自由的修改本脚本和反馈本脚本的各种错误和不足。

##本脚本的作用：
##    在一个全新的CentOS系统上编译安装nginx1.6.2 cmake3.1 php5.5.20 
##    MariaDB10.0.15 zabbix2.4.6 或者 安装zabbix Agent端
##
##    实现一个基于LNMP环境的zabbix server端配置 或zabbix agent端配置
