本文基于《LNMP最新源码安装脚本》,Nagios依赖PHP环境和perl环境,由于Nginx不支持Perl的CGI,需先来搭建Perl环境,Nagios原理介绍略。
1、下载最新稳定源码包和Perl脚本
wget http://www.cpan.org/modules/by-module/FCGI/FCGI-0.74.tar.gz
wget http://www.cpan.org/authors/id/B/BO/BOBTFISH/FCGI-ProcManager-0.24.tar.gz
wget http://blog.Linuxeye.com/wp-content/uploads/2013/04/perl-fcgi.pl
wget http://jaist.dl.sourceforge.net/project/nagios/nagios-3.x/nagios-3.5.0/nagios-3.5.0.tar.gz
wget http://nchc.dl.sourceforge.net/project/nagiosplug/nagiosplug/1.4.16/nagios-plugins-1.4.16.tar.gz
wget http://nchc.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.14/nrpe-2.14.tar.gz
 
2、Nginx对Perl的CGI支持
Nginx支持Perl的CGI方法有好几种,基本原理都是通过Perl的FCGI模块实现,下面的方法就是其中一种:
安装FCGI模块
tar xzf FCGI-0.74.tar.gz
cd FCGI-0.74
perl Makefile.PL
make && make install
cd ../
安装FCGI-ProcManager模块
tar xzf FCGI-ProcManager-0.24.tar.gz
cd FCGI-ProcManager-0.24
perl Makefile.PL
make && make install
cd ../
安装IO模块
tar xvf IO-1.25.tar.gz
perl Makefile.PL
make && make install
cd ..
安装IO-All模块
tar xvf IO-All-0.39.tar.gz
cd IO-All-0.39
perl Makefile.PL
make && make install
 
启动方法一:
Perl脚本
cp perl-fcgi.pl /usr/local/nginx
chmod +x /usr/local/nginx/perl-fcgi.pl
/usr/local/nginx/perl-fcgi.pl > /usr/local/nginx/logs/perl-fcgi.log 2>&1 & #启动Perl
chmod 777 /usr/local/nginx/logs/perl-fcgi.sock #Nginx Log中提示Permision Denied方法
 
启动方法二:
下载nginx-fcgi脚本
Wget http://www.nginx.eu/nginx-fcgi/nginx-fcgi.txt
#mv nginx-fcgi.txt /usr/sbin/nginx-fcgi
#chmod +x /usr/sbin/nginx-fcgi
mv nginx-fcgi.txt  /usr/local/nginx/sbin/nginx-fcgi (我的nginx安装位置)
chmod +x /usr/local/nginx/sbin/nginx-fcgi 
如果不用 sudo 方式运行 nginx-fcgi,请注释掉 nginx-fcgi 脚本中的:
 
    if ( $> == "0" ) {
            print "\n\tERROR\tRunning as a root!\n";
            print "\tSuggested not to do so !!!\n\n";
            exit 1;
    }
 
启动 nginx-fcgi:
/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
chown nginx:nginx  /usr/local/nginx/logs/nginx-fcgi.sock
注意一定要为 socket 添加 nginx 帐户的权限,否则 cgi 会执行失败。
运行前使用cpan 安装 FCGI;  Getopt::Long;  Socket;
 
设置开机启动(添加到/etc/rc.loacl文件)
/bin/rm -rf /usr/local/nginx/logs/nginx-fcgi.pid
/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
chmod 777 /usr/local/nginx/logs/nginx-fcgi.sock
 
新建 nginx-fcgi 脚本指令配置,直接从 fastcgi_params 复制模板:
 
    cp /etc/nginx/fastcgi_params /etc/nginx/nginx_fcgi_params
 
去除尾部的:
 
    # PHP only, required if PHP was built with –enable-force-cgi-redirect
    fastcgi_param  REDIRECT_STATUS    200;
 
新建示例 cgi 站点配置:
 
    server {
        listen       80;
        server_name  test.local;
 
        location ~ ^/cgi-bin/.*\.cgi$
        {
            root           /work/www/test;
            fastcgi_index  index.cgi;
            fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
            include        nginx_fcgi_params;
            fastcgi_read_timeout    5m;
            fastcgi_pass   unix:/var/run/nginx-fcgi.sock;
        }
    }
 
重启 nginx,cgi配置完成。
 
3、Nagios安装(服务端)
useradd nagios
groupadd nagcmd
usermod -a -G nagcmd nagios
usermod -a -G nagcmd www
tar xzf nagios-3.5.0.tar.gz
cd nagios
yum -y install gd gd-devel
./configure --prefix=/usr/local/nagios --with-command-group=nagcmd --with-htmurl=/ –with-cgiurl=/cgi-bin
make all
make install #用于安装主要的程序、CGI及HTML文件
make install-init #用于生成init启动脚本
make install-config #用于安装示例配置文件
make install-commandmode #用于设置相应的目录权限
chkconfig --add nagios
chkconfig nagios on
cd ../
 
Nagios主程序只是提供一个运行框架,其具体监控是靠运行在其下的插件完成的,Nagios插件必须安装
tar xzf nagios-plugins-1.4.16.tar.gz
cd nagios-plugins-1.4.16
./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios
make && make install
cd ../
 
配置Nagios Web界面登陆帐号及密码
借用Apache的htpasswd命令工具
yum install httpd
service httpd stop && chkconfig httpd off   #不启用Apache
/usr/local/apache/bin/htpasswd -nb nagiosadmin 123456 > /usr/local/nagios/etc/htpasswd.users
生成加密文件
cat /usr/local/nagios/etc/htpasswd.users
nagiosadmin:wqx7mC26z5vKs
 
* 修改配置文件
 
打开 /usr/local/nagios/etc/cgi.cfg,修改 use_authentication 为:
 
    use_authentication=0
 
即去除用户验证,然后重启 nagios。
 
打开 /usr/local/nagios/share/config.inc.php,把:
 
    $cfg['cgi_base_url']='/nagios/cgi-bin';
 
改为(根据自己的实际情况修改):
 
    $cfg['cgi_base_url']='/cgi-bin';
 
如果报错:Error: No such CGI app - /usr/local/nagios/sbin/cgi-bin/status.cgi may not exist or is not executable by this process.
则一般都是这里的错误,此处修改的位置根据上面configure编译nagios时定义–with-cgiurl=/cgi-bin修改,本人的这次安装不知道哪里出问题,编译nagios带参数–with-cgiurl=/cgi-bin,此处却必须为 $cfg['cgi_base_url']='/nagios/cgi-bin';不能修改,可能带的参数编译不成功
 
启动前先检查下配置文件是否正确
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
如果没有报错,可以启动Nagios服务
/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
【或者/etc/init.d/nagios start】
查看nagios监控状态
/usr/local/nagios/bin/nagiostats
