nagios搭建
最近搭建了两次nagios，第一次工作忙碌没有记录下过程；这次抽了时间简单的记录了搭建过程。系统版本：centos 6.3 64位
软件版本：nagios-3.4.3.tar.gz
nagios-plugins-1.4.16.tar.gz
nrpe.tar.gz
httpd-2.2.23.tar.gz
php-5.4.10.tar.gz
这次尝试了利用yum安装的http，php；可惜到最后没有成功，鉴于老大那里急着要只有编译安装了httpd和php（nagios3.0版本需要php的支持）。
开始：
1：检查依赖安装

rpm -q gcc glibc glibc-common gd gd-devel xinetd openssl-devel
如果没有安装请执行：
yum -y install gcc glibc glibc-common gd gd-devel xinetd openssl-devel
