Nginx下搭建Nagios

Nagios的搭建主要是需要PHP和Perl的CGI的支持

首先,让Nginx支持CGI

1、安装FCGI模块

wget http://search.cpan.org/CPAN/authors/id/F/FL/FLORA/FCGI-0.73.tar.gz
tar xvzf FCGI-0.73.tar.gz

cd FCGI-0.73

perl Makefile.PL

make

make install

2、安装FCGI-ProcManager模块

wget http://search.cpan.org/CPAN/authors/id/G/GB/GBJK/FCGI-ProcManager-0.19.tar.gz
tar xvzf FCGI-ProcManager-0.19.tar.gz

cd FCGI-ProcManager-0.19

perl Makefile.PL

make

make install

3、安装IO和IO::ALL模块

wget http://search.cpan.org/CPAN/authors/id/G/GB/GBARR/IO-1.25.tar.gz
tar zxvf IO-1.25.tar.gz

cd IO-1.25

perl Makefile.PL

make

make install

wget http://search.cpan.org/CPAN/authors/id/I/IN/INGY/IO-All-0.41.tar.gz
tar zxvf IO-All-0.41.tar.gz

cd IO-All-0.41

perl Makefile.PL

make

make install

4、下载Perl脚本

这个脚本的目的就是产生一个PERL的FastCGI接口，让Nginx可以以CGI方式处理Perl。

wget http://www.mike.org.cn/wp-content/uploads/2011/07/perl-fcgi.zip
unzip perl-fcgi.zip

cp perl-fcgi.pl /usr/local/nginx/

注：建议把这个脚本放在Nginx安装目录。

修改脚本权限

chmod 755 /usr/local/nginx/perl-fcgi.pl

5、建立一个CGI启动/停止脚本

这个SHELL脚本只是为了方便管理上面的Perl脚本。脚本中的www为nginx的运行用户，请据自己的实际情况调整。

注意事项：不能用root用户执行(会提示). 要用与Nginx相同身份的用户执行。否则可能会在Nginx Log中提示 Permision Denied。

vim /etc/init.d/perl-cgi.sh

#!/bin/bash

dir=/usr/local/nginx

stop ()

{

#pkill -f $dir/perl-fcgi.pl

kill $(cat $dir/logs/perl-fcgi.pid)

rm $dir/logs/perl-fcgi.pid 2>/dev/null

rm $dir/logs/perl-fcgi.sock 2>/dev/null

echo "stop perl-fcgi done"

}

start ()

{

rm $dir/now_start_perl_fcgi.sh 2>/dev/null

chown www.www $dir/logs

echo "$dir/perl-fcgi.pl -l $dir/logs/perl-fcgi.log -pid $dir/logs/perl-fcgi.pid -S $dir/logs/perl-fcgi.sock" >>$dir/now_start_perl_fcgi.sh

chown www.www $dir/now_start_perl_fcgi.sh

chmod u+x $dir/now_start_perl_fcgi.sh

sudo -u www $dir/now_start_perl_fcgi.sh

echo "start perl-fcgi done"

}

case $1 in

stop)

stop

;;

start)

start

;;

restart)

stop

start

;;

esac

修改SHELL脚本权限

chmod 755 /etc/init.d/perl-cgi.sh

启动脚本

/etc/init.d/perl-cgi.sh restart

正常情况下在/usr/local/nginx/logs下生成perl-fcgi.sock这个文件,如果没有生成,请检查下上面的步聚。

nginx下nagios.conf

server

{

listen 80;

server_name nagios.ylwkj.com;

index index.html index.htm index.php;

root /usr/local/nagios/share;

auth_basic "Nagios Access";

auth_basic_user_file /usr/local/nagios/etc/.passwd.conf;

location ~ .*\.(php|php5)?$

{

#fastcgi_pass unix:/tmp/php-cgi.sock;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

include fcgi.conf;

}

location ~ .*\.(cgi|pl)?$

{

gzip off;

root /usr/local/nagios/sbin;

rewrite ^/nagios/cgi-bin/(.*)\.cgi /$1.cgi break;

fastcgi_pass unix:/usr/local/nginx/logs/perl-fcgi.sock;

fastcgi_param SCRIPT_FILENAME /usr/local/nagios/sbin$fastcgi_script_name;

fastcgi_index index.cgi;

fastcgi_read_timeout 60;

fastcgi_param REMOTE_USER $remote_user;

include fcgi.conf;

}

location /nagios/

{

alias /usr/local/nagios/share/;

}

location /nagios/cgi-bin/

{

alias /usr/local/nagios/sbin;

}

location /nagios/cgi-bin/image/

{

alias /usr/local/nagios/share/images/;

}

access_log /data/logs/nagios_access.log www;

error_log /data/logs/nagios_error.log;

}

关于修改通知:

搜索网上都没解决，我研究了下，找到了解决方法：

关键是提交的时候使用了post，估计是nginx下不支持这个post，到源代码目录的cgi目录，找到cmd.c文件，搜索post，只有一个，修改为get，然后重新make，拷贝新make出来的cmd.cgi到安装目录替换掉旧的
