安装环境：CentOS5.5
1、下载相关软件
FCGI-0.67.tar.gz
FCGI-ProcManager-0.18.tar.gz
IO-All-0.39.tar.gznagios-3.2.3.tar.gznagios-plugins-1.4.15.tar.gz
2、建立相关用户
useradd nagios
groupadd nagcmd
usermod -g nagcmd nagios
usermod -g nagcmd www
3、安装Nagios
tar zxvf nagios-3.2.3.tar.gz
cd nagios-3.2.3
./configure --with-group=nagios --with-user=nagios --with-command-group=nagcmd --with-gd-lib=/usr/lib --with-gd-inc=/usr/include
make all
make install
make install-init
make install-config
make install-commandmode
4、安装Nagios插件
tar zxvf nagios-plugins-1.4.15.tar.gz
cd nagios-plugins-1.4.15
./configure --with-nagios-user=nagios --with-nagios-group=nagios
make
make install
5、配置Nagios启动
nagios chkconfig --add nagios
chkconfig nagios on
service nagios start
6、安装Perl fcgi模块，让Nginx支持CGI
tar -zxf FCGI-0.67.tar.gz
cd FCGI-0.67
perl Makefile.PL
make && make install
tar -zxf FCGI-ProcManager-0.18.tar.gz
cd FCGI-ProcManager-0.18
perl Makefile.PL
make && make install
tar zxf IO-All-0.39.tar.gz
cd IO-All-0.39
perl Makefile.PL
make && make install
建立nginx-fcgi脚本
vi /usr/local/nginx/sbin/nginx-fcgi
把下面内容写进脚本，并授执行权限#!/usr/bin/perl

chmod +x /usr/local/nginx/sbin/nginx-fcgi
运行脚本：
/usr/local/nginx/sbin/nginx-fcgi -l /usr/local/nginx/logs/nginx-fcgi.log -pid /usr/local/nginx/logs/nginx-fcgi.pid -S /usr/local/nginx/logs/nginx-fcgi.sock
把sock授权777：
chmod 777/usr/local/nginx/logs/nginx-fcgi.sock
