How to install FastCGI/php-fpm with Apache in Ubuntu 16.04 LTS

Introduction

In the web Server Apache is one of the popular web server which is mostly use in our server environment by hosting providers and it easily handles php through default handler which is cgi and php-fpm is FastCGI implementation very simple to setup on server. It uses as backed for heavy application for php to run php cgi fast as compare to normal cgi application. It has very fast processing PHP website/scripts for large traffic sites.

Apache runs by default working on mod_php which takes more resources comparative to php-fpm. So today we are going to install php-fpm with Apache to compile php scripting through php-fpm.

Please follow installation steps:-

solutionclub:~# apt-get update
solutionclub:~# apt-get install apache2-mpm-event
solutionclub:~# a2dismod mpm_worker
solutionclub:~# a2enmod mpm_event

Now The Time,We need to restart apache2 once

solutionclub:~# systemctl restart apache2

After restart You Should check Apache status

solutionclub:~# systemctl status apache2

 apache2.service - LSB: Apache2 web server
   Loaded: loaded (/etc/init.d/apache2; bad; vendor preset: enabled)
  Drop-In: /lib/systemd/system/apache2.service.d
           └─apache2-systemd.conf
   Active: active (running) since Mon 2018-03-05 10:02:25 IST; 8h ago
     Docs: man:systemd-sysv-generator(8)

           ├─1202 /usr/sbin/apache2 -k start
           ├─1203 /usr/sbin/apache2 -k start
           ├─1204 /usr/sbin/apache2 -k start
           ├─1205 /usr/sbin/apache2 -k start
           └─1206 /usr/sbin/apache2 -k start

Now install libapache2-mod-fastcgi

Note: If you are not success to install libapache2-mod-fastcgi package then add repo in sources.list /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

solutionclub:~# apt-get update
solutionclub:~# apt-get install libapache2-mod-fastcgi

Now you ready to install php-fpm

solutionclub:~# apt-get install php-fpm

PHP-FPM is not auto binding with apache. So we require to configure apache. Let us check how to configure.

solutionclub:~# vim   /etc/apache2/conf-available/php-fpm.conf

Now you just copy and paste these line in conf file.

<IfModule mod_fastcgi.c>
      AddHandler php7-fcgi .php
      Action php7-fcgi /php7-fcgi
      Alias /php7-fcgi /usr/lib/cgi-bin/php7-fcgi
      FastCgiExternalServer /usr/lib/cgi-bin/php7-fcgi -socket /var/run/php/php7.0-fpm.sock -pass-header Authorization

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

Now We need to enable this module with Apache and enable php-fpm configuration also .

solutionclub:~# a2enmod actions fastcgi alias
solutionclub:~# a2enconf php-fpm

Finally we can restart Apache service for have effect.

solutionclub:~# systemctl restart apache2

Now Add phpinfo file in your Apache root folder

solutionclub:~# echo "<?php phpinfo(); ?>" >> /var/www/html/index.php

When You restart Apache service check it on http://server-ip-address/index.php
