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.
Installation of version 7.1
# dnf module install php:7.1 Dependencies resolved. ========================================================================================================== Package Arch Version Repository Size ========================================================================================================== Installing group/module packages: php-cli x86_64 7.1.20-2.el8+1700+11d526eb rhel-8-for-x86_64-appstream-beta-rpms 2.9 M php-common x86_64 7.1.20-2.el8+1700+11d526eb rhel-8-for-x86_64-appstream-beta-rpms 624 k php-fpm x86_64 7.1.20-2.el8+1700+11d526eb rhel-8-for-x86_64-appstream-beta-rpms 1.5 M php-json x86_64 7.1.20-2.el8+1700+11d526eb rhel-8-for-x86_64-appstream-beta-rpms 70 k php-mbstring x86_64 7.1.20-2.el8+1700+11d526eb rhel-8-for-x86_64-appstream-beta-rpms 547 k php-xml x86_64 7.1.20-2.el8+1700+11d526eb rhel-8-for-x86_64-appstream-beta-rpms 187 k Installing dependencies: httpd-filesystem noarch 2.4.35-6.el8+2089+57a79027 rhel-8-for-x86_64-appstream-beta-rpms 32 k nginx-filesystem noarch 1:1.14.0-3.el8+1631+ba902cf0 rhel-8-for-x86_64-appstream-beta-rpms 23 k Installing module profiles: php/default Enabling module streams: httpd 2.4 nginx 1.14 php 7.1 Transaction Summary ========================================================================================================== Install 8 Packages Total download size: 5.9 M Installed size: 20 M Is this ok [y/N]: y

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).

Hi!
I saw that the package scl-utils still exists in rhel8 (at lest in the beta)
So, do you plan to still create software collections for RHEL8 /CentOS8 (specifically for PHP)? I have been a happy user of software collections for php-fpm as a way to provide multi-version php. I will switch to containers is needed, but if software collections still exist in RHEL8 that would be a less-worl, lower-risk option for me.
Thanks for your great work!

Yes, probably.
Cool! Thanks for your fast reply!
