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.gz libiconv-1.13.1.tar.gz php-5.3.10.tar.gz nagios-3.3.1.tar.gz nagios-plugins-1.4.15.tar.gz nrpe-2.13.tar.gz
使用方法：
cd /root wget //linuxeye.com/wp-content/uploads/nagios.zip unzip nagios.zip cd nagios sh nagios_install.sh
