nagios安装与配置脚本 | Linux运维笔记

以下为nagios的安装与配置脚本，脚本中server:192.168.1.114、client:192.168.1.113，主要监控host-alive、disk、cpu_procs、load、ssh、swap、users、zombie_procs等，请根据实际环境修改配置文件。脚本中开源软件版本(最新稳定版)：

httpd-2.2.22.tar.gzlibiconv-1.13.1.tar.gzphp-5.3.10.tar.gznagios-3.3.1.tar.gznagios-plugins-1.4.15.tar.gznrpe-2.13.tar.gz

使用方法：

cd rootwget /blog.linuxeye.com/wp-content/uploads/nagios.zipunzip nagios.zipcd nagiossh nagios_install.sh
