Introduction

Apache is popular web server software which is mostly used in our server environment by hosting providers and it handles php through default handler which is cgi .PHP5-FPM is FastCGI implementation for PHP. it uses as backed application for php to run php cgi as fast compare to normal cgi application. It is useful for processing PHP scripts for large traffic sites.

Apache runs by default with mod_php which takes more resources then php-fpm. So we are here going to install php-fpm with apache to compile php scripting through php-fpm.

Installation Steps

Step 1. Install apache2 with mod-mpm-event

First of all update repository and install apache with mpm event.

linuxtweaks ~]#sudo apt-get update
linuxtweaks ~]#sudo apt-get install apache2-mpm-event

When apache successfully install we can check apache service if it’s running

linuxtweaks ~]#sudo service apache2 status

if it’s not running you can start it by following command-

linuxtweaks ~]#service apache2 start

Step 2.  Install libapache2-mod-fastcgi

Next we have to install libapache2-mod-fastcgi module for apache to working with php-fpm.


As this module is not included with default repo so we have to add repolist in apt repository.

Open below files and add repository location

linuxtweaks ~]#sudo vi /etc/apt/sources.list

deb http://us.archive.ubuntu.com/ubuntu/ trusty multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty multiverse
deb http://us.archive.ubuntu.com/ubuntu/ trusty-updates multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty-updates multiverse

Copy above lines and add in sources.list at the end of file.

Now update repository and install apache module

linuxtweaks ~]#sudo apt-get update
linuxtweaks ~]#sudo apt-get install libapache2-mod-fastcgi

Step 3. Install php5-fpm

Install php-fpm with following command

linuxtweaks ~]#sudo apt-get install php5-fpm

Step 4. Configure Php-fpm with apache

Create new file and configure php-fpm for apache

linuxtweaks ~]#vi /etc/apache2/conf-available/php5-fpm.conf

add the following line of code in above file –

<IfModule mod_fastcgi.c>
AddHandler php5-fcgi .php
Action php5-fcgi /php5-fcgi
Alias /php5-fcgi /usr/lib/cgi-bin/php5-fcgi
FastCgiExternalServer /usr/lib/cgi-bin/php5-fcgi -socket /var/run/php5-fpm.sock -pass-header Authorization

<Directory /usr/lib/cgi-bin>
    Require all granted
</Directory>

</IfModule>

After completion of configuration of php-fpm we need to enable this module with apache and enable php-fpm configuration as well.

linuxtweaks ~]#a2enmod actions fastcgi alias
linuxtweaks ~]#a2enconf php5-fpm

Finally we can restart apache service for take effect

linuxtweaks ~]#service apache2 restart

Step 5. Testing

Create a phpinfo file for checking if everything works as per our requirement.

linuxtweaks ~]#vi /var/www/html/phpinfo.php

Add the following line of code

<?php phpinfo(); ?>

And check through http://server-ip-address/phpinfo.php

You will see fastcgi/FPM for apache handler.
