Apache 2.4 mpm_event + php-fpm in CentOS 7

Add remi repo + epel +codeit repo.

yum install -y epel-release yum-utils http://rpms.remirepo.net/enterprise/remi-release-7.rpm
cd /etc/yum.repos.d && wget https://repo.codeit.guru/codeit.el`rpm -q --qf "%{VERSION}" $(rpm -q --whatprovides redhat-release)`.repo

 

Enable remi repo PHP 7.2 branch

yum-config-manager --enable remi-php72

Install Apache + php + php-fpm

yum install httpd php php-fpm php-common php-cli php-pear php-pdo php-mysqlnd php-pgsql php-opcache php-gd php-mbstring php-mcrypt php-xml mod_ssl mod_http2

 

Enable both httpd and php-fpm to systemd auto-start routine.

systemctl enable php-fpm.service
systemctl enable httpd.service

 

 

Edit /etc/httpd/conf/httpd.conf and add these lines at the bottom of the file.


<IfModule mpm_prefork_module>
php_value session.save_handler "files"
php_value session.save_path "/var/lib/php/session"
</IfModule>

Edit /etc/httpd/conf.modules.d/00-mpm.conf file to turn on the mpm_event module.

Comment out this line,


LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

and uncomment this line.


LoadModule mpm_event_module modules/mod_mpm_event.so

Final result of the said 00-mpm.conf file should look like below:-


# Select the MPM module which should be used by uncommenting exactly
# one of the following LoadModule lines:

# prefork MPM: Implements a non-threaded, pre-forking web server
# See: http://httpd.apache.org/docs/2.4/mod/prefork.html
#LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

# worker MPM: Multi-Processing Module implementing a hybrid
# multi-threaded multi-process web server
# See: http://httpd.apache.org/docs/2.4/mod/worker.html
#
#LoadModule mpm_worker_module modules/mod_mpm_worker.so

# event MPM: A variant of the worker MPM with the goal of consuming
# threads only for connections with active processing
# See: http://httpd.apache.org/docs/2.4/mod/event.html
#
LoadModule mpm_event_module modules/mod_mpm_event.so

 

For any virtual host you want to have PHP enabled, open its corresponding .conf file and add these lines:-


<IfModule mpm_event_module>
ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/path/to/website/root/$1
</IfModule>

So, if you want to enable PHP on a virtual host that is located at /var/www/html folder, the .conf file should look roughly like below:-


<VirtualHost 123.123.123.123:80>
DocumentRoot "/var/www/html"
ServerName example.com
ServerAlias www.example.com
ErrorLog /dev/null
CustomLog /dev/null combined

<IfModule mpm_event_module>
ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/var/www/html/$1
</IfModule>

<Directory "/var/www/html">
Require all granted
allow from all
</Directory>
</VirtualHost>

Start both php-fpm and httpd.


systemctl start php-fpm
systemctl start httpd
