搭建基于apache的nagios系统比较容易，网上的资料也比较多。可是在nginx环境下就有点费劲了，因为nginx本身不支持CGI，所以需要在三方程序的配合下，才能实现CGI的解析。
本文只讲述安装部分，有机会再给大家补上配置部分。下面就开始学习在nginx环境下安装，安装nagios监控系统。
准备工作：
下载安装包：
wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.4.1.tar.gz
wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.16.tar.gz
wget http://prdownloads.sourceforge.net/sourceforge/nagios/nrpe-2.13.tar.gz
wget http://www.cpan.org/modules/by-module/FCGI/FCGI-0.67.tar.gz
wget http://search.cpan.org/CPAN/authors/id/G/GB/GBJK/FCGI-ProcManager-0.18.tar.gz
wget http://search.cpan.org/CPAN/authors/id/G/GB/GBARR/IO-1.25.tar.gz
wget http://search.cpan.org/CPAN/authors/id/I/IN/INGY/IO-All-0.39.tar.gz
添加相关用户：
groupadd nagios
useradd -g nagios nagios
开始安装：
编译安装nagios：
tar zxvf nagios-3.4.1.tar.gz
cd nagios
./configure --prefix=/data/app/nagios --with-nagios-user=nagios --with-nagios-group=nagios
make all
make install
make install-init
make install-commandmode
make install-config
cd ..
编译安装nagios插件：
tar zxvf nagios-plugins-1.4.16.tar.gz
cd nagios-plugins-1.4.16
./configure --prefix=/data/app/nagios --with-nagios-user=nagios --with-nagios-group=nagios
make
make install
cd ..
编译安装nrpe:
tar zxvf nrpe-2.13.tar.gz
cd nrpe-2.13
./configure --prefix=/data/app/nagios --with-nrpe-user=nagios --with-nrpe-group=nagios
make
make install
cd ..
安装perl，CGI脚本是用perl实现的:
yum install perl
编译安装perl脚本所需要调用的组件：
tar zxvf FCGI-0.67.tar.gz
cd FCGI-0.67
perl Makefile.PL
make
make install
cd ..
tar zxvf FCGI-ProcManager-0.18.tar.gz
cd FCGI-ProcManager-0.18
perl Makefile.PL
make
make install
cd ..
tar zxvf IO-1.25.tar.gz
cd IO-1.25
perl Makefile.PL
make
make install
tar zxvf IO-All-0.39.tar.gz
cd IO-All-0.39
perl Makefile.PL
make
make install
下载并配置可是实现CGI解析的脚本：
cd /data/app/nginx/sbin/
wget http://www.linux8080.com/perl-fcgi.pl
chmod +x perl-fcgi.pl
chown nginx.nginx perl-fcgi.pl
/data/app/nginx/sbin/perl-fcgi.pl -pid /var/run/nginx-fcgi.pid -S /var/run/nginx-fcgi.sock -l /var/log/perl-fcgi.log
cd /var/run
chmod 777 nginx-fcgi.sock
创建登录nagios的用户账户和密码文件：
cd /data/app/nagios/etc/
htpasswd -c htpasswd nagios
配置nginx虚拟主机并重启：
server {
listen 80;
server_name 10.10.10.200;
index index.html index.htm index.php;
root /data/www/html;
location ~ .*.(cgi|pl)?$
{
gzip off;
root /data/app/nagios/sbin;
rewrite ^/nagios/cgi-bin/(.*).cgi /$1.cgi break;
fastcgi_pass unix:/var/run/nginx-fcgi.sock;
fastcgi_param SCRIPT_FILENAME /data/app/nagios/sbin$fastcgi_script_name;
fastcgi_index index.cgi;
fastcgi_read_timeout 60;
fastcgi_param REMOTE_USER $remote_user;
include fcgi.conf;
}
location ~ ^/nagios/.+.php$
{
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fcgi.conf;
auth_basic "Nagios Access";
auth_basic_user_file /data/app/nagios/etc/htpasswd;
}
}
创建软连接：
ln -s /data/app/nagios/share /data/www/html/nagios
登录后的界面如下：
