Install PHP-FPM in Wikimedia Italia VPS wmi-fabula (to coexist PHP 5.6 with 7.3)
Closed, ResolvedPublic
Actions

Description

Preamble

Wikimedia Italia has a VPS recently called wmi-fabula (Wikimedia Italia server details) running Centos7 and serving lot of websites sharing PHP 5.6 as shared dependency.

Currently it serves nearly 100 virtualhosts (!).

At the time of writing we have an Apache HTTPd configured with the mod_php module.

Proposal

Our VPS should allow to serve websites requiring recent versions of PHP like PHP7 and without impacting in any way legacy websites needing the old PHP 5.6.

This thing is currently not possible and blocks this

Additionally, this forces us to rely on another server belonging to a volunteer to deploy this kind of recent applications.

Also, this feature would also simplify our migrations to recent versions of PHP for our legacy websites. At the time of writing it's difficult (or nearly impossible!) to deal with such bulk migration (again, we have 100 virtualhosts).

Proposed solution

We can achieve the result of supporting two or more PHP versions adopting a recent php-fpm package together with mod_php. This should allow to leave the legacy configurations as-is and just introduce a new virtualhost proxying to the internal PHP-FPM running PHP 7.3.

Some progresses here.

I was able to install a virtual machine with Centos 7 and see mod_php (PHP 5.6) working alongside with php_fpm (PHP 7.3.20) installing rh-php73-php-fpm and a proxy.

I was following this reference:

$ systemctl enable --now rh-php73-php-fpm

It seems it's working.

To use this, just add something as this in your Apache HTTPd virtualhost:

        #
	# We are using the Centos 7 package 'rh-php72-php-fpm'
        #

In Centos 7 PHP sessions are broken.

Issued:

mkdir        /var/lib/php/session
chown apache /var/lib/php/session

Holy shit I hate Centos 7.

To avoid mistake I've disabled this service:

systemctl mask php-fpm.service
WARNING: ALWAYS START THE rh-php73-php-fpm service and not the php-fpm service!
