Remi Collet: PHP on RHEL-8

RHEL-8 Beta is announced and is available for download for whom want to try it.

This is an opportunity to look at PHP installation and how modules work.

1. Installation

ISO image is available for everyone, see the README file.

Don’t forget to enable the Beta repositories.

# dnf repolist
repo id                               repo name                                                     status
rhel-8-for-x86_64-appstream-beta-rpms Red Hat Enterprise Linux 8 for x86_64 - AppStream Beta (RPMs) 4594
rhel-8-for-x86_64-baseos-beta-rpms    Red Hat Enterprise Linux 8 for x86_64 - BaseOS Beta (RPMs)    1686

2. Installation of PHP

PHP is not part of BaseOS which is the base of the Operating System, reduced to minimal, but is available in AppStream, i.e. as a module.

# dnf module list
Red Hat Enterprise Linux 8 for x86_64 - AppStream Beta (RPMs)
php                  7.1          devel, minimal, defaul PHP scripting language                           
                                  t [d]                 
php                  7.2 [d]      devel, minimal, defaul PHP scripting language                           
                                  t [d]                  

You can see that both versions 7.1 and 7.2 (default) are available.

3. Web usage

3.1 with Apache HTTP Server

Installation:

# dnf module install httpd

Service activation:

# systemctl enable --now php-fpm
# systemctl enable --now httpd

Test page:

# echo '<?php phpinfo();' >/var/www/html/info.php

Then you can browse to http://localhost/info.php

3.2 with nginx

Installation:

# dnf module install nginx

Services activation:

# systemctl enable --now php-fpm
# systemctl enable --now nginx

Test page:

# echo '<?php phpinfo();' >/usr/share/nginx/html/info.php

Then you can browse to http://localhost/info.php

4. Conclusion

Fedora users won’t be surprised, RHEL users can now take benefits of work done on PHP packages since F19:

  • php-fpm used by default
  • httpd using MPM event by default, and php working without any configuration change
  • nginx available, and php working without any configuration change

Usage of modules should improve flexibility in version choice, and usability, and of course, we can expect new versions sooner (e.g. php 7.3).

Some (like me) will miss the Software Collections and so the possible installation of multiple versions simultaneously (still possible using containers).
