Nagios platform migrating from Apache to Nginx

Nginx's performance is far superior to Apache, but because Nagios's web interface contains PHP and C-CGI programs, it requires two sets of fcgi management tools (not required) and two sets of interpreters (must). PHP with php-cgi Run can, c-cgi I choose Fcgiwrap. The installation/configuration steps are described below.

php-fpm: A fastcgi management patch for PHP that can smoothly change php.ini configuration without restarting php-cgi
spawn-fcgi: is a branch project of LIGHTTPD, a manager of a CGI process

PHP hits PHP-FPM patches,--enable-fastcgi--enable-fpm parameters are enabled at compile time, PHP-FPM management php-cgi is used. PHP installation Detailed steps see Zhang Yi article: http://blog.s135.com/nginx_php_v5/
C-CGI uses spawn-fcgi management, using Fcgiwrap drivers. Fcgiwrap Introduction See Http://nginx.localdomain.pl/wiki/FcgiWrap

php-cgi Monitor 127.0.0.1:9000
Fcgiwrap Monitor 127.0.0.1:10000

Nagios installation configuration is not the focus of this article, skip. The Web directory is as follows:
/usr/local/nagios/share

Installing spawn-fcgi

wget Http://download.lighttpd.net/spawn-fcgi/releases-1.6.x/spawn-fcgi-1.6.3.tar.gztar XF spawn-fcgi-1.6.3.tar.gzcd/usr/local/src/spawn-fcgi-1.6.3./configure--prefix=/usr/local/spawn-fcgimake & & Make Install

Installing the FCGI Library

wget Http://dl.fedoraproject.org/pub/epel/6/x86_64/fcgi-2.4.0-10.el6.x86_64.rpmwget http://dl.fedoraproject.org/ PUB/EPEL/6/X86_64/FCGI-DEVEL-2.4.0-10.EL6.X86_64.RPMRPM-IVH FCGI-2.4.0-10.EL6.X86_64.RPMRPM-IVH fcgi-devel-2.4.0-10.el6.x86_64.rpm

Note : the above fcgi software rpm for RHEL6 corresponding version, if is 5 series please install RHEL5 corresponding version of the FCGI Library, RHEL5 software as follows:

fcgi:http://flexbox.sourceforge.net/centos/5/x86_64/fcgi-2.4.0-10.el5.x86_64.rpm

fcgi-devel:http://flexbox.sourceforge.net/centos/5/x86_64/fcgi-devel-2.4.0-10.el5.x86_64.rpm

Installing Fcgiwrap

Fcgiwrap Wiki--Http://nginx.localdomain.pl/wiki/FcgiWrap

The latest version is gnosek-fcgiwrap-1.1.0-0-g333ff99.tar.gz

CD gnosek-fcgiwrap-333ff99/autoreconf-i./configure--prefix=/usr/local/fcgiwrapmake && make install

Create a shell script to start the Fcgiwrap instance with spawn-fcgi

Vi/usr/local/bin/c-fcgi.sh#!/bin/sh/usr/local/spawn-fcgi/bin/spawn-fcgi-f/usr/local/fcgiwrap/bin/fcgiwrap-a 127.0.0.1-p 10000-f 3-p/var/run/fastcgi-c.pid-u daemon-g daemonchmod +x/usr/local/bin/c-fcgi.sh

The parameters have the following meanings:

-F <fcgiapp> Specifies the execution program location of the process calling FastCGI

-A <addr> bind to address addr

-P <port> bind to ports port

-S <path> path bound to Unixsocket

-C < children> Specifies the number of processes generated for fastcgi (PHP only)

-F <children> Specifies the number of processes generated by the fastcgi

-P <path> Specify PID file path for the resulting process

What identity is used by-u and-G fastcgi (-u user-G user group), which runs with Nginx user and group daemon

Create a system boot process that facilitates the use of service and chkconfig command tubes
