Repositories configuration:

On Fedora, standards repositories are enough, on Enterprise Linux (RHEL, CentOS) the Extra Packages for Enterprise Linux (EPEL) repository must be configured, and on RHEL the optional channel must be enabled.

Fedora 33

dnf install

Fedora 32

dnf install

RHEL version 8.3

dnf install
dnf install

RHEL version 7.9

rpm -Uvh remi-release-7.rpm epel-release-latest-7.noarch.rpm
subscription-manager repos --enable=rhel-7-server-optional-rpms

CentOS version 8

dnf install
dnf install

CentOS version 7

rpm -Uvh remi-release-7.rpm epel-release-latest-7.noarch.rpm


php module usage

With Fedora modular and RHEL / CentOS 8, you can simply use the remi-8.0 stream of the php module

dnf module reset php
dnf module install php:remi-8.0


remi-php80 repository activation

Needed packages are in the remi-safe (enabled by default) and remi-php80 repositories, the latest is not enabled by default (administrator choice according to the desired PHP version).

RHEL or CentOS 7

yum install yum-utils
yum-config-manager --enable remi-php80


dnf config-manager --set-enabled remi-php80


PHP upgrade

By choice, the packages have the same name than in the distribution, so a simple update is enough:

yum update

That's all :)

$ php -v
PHP 8.0.0 (cli) (built: Nov 24 2020 17:04:03) ( NTS gcc x86_64 )
Copyright (c) The PHP Group
Zend Engine v4.0.0-dev, Copyright (c) Zend Technologies
    with Zend OPcache v8.0.0, Copyright (c), by Zend Technologies


Known issues

The upgrade can fail (by design) when some installed extensions are not yet compatible with  PHP 8.0.

See the compatibility tracking list: PECL extensions RPM status

If these extensions are not mandatory, you can remove them before the upgrade, else, you will have to be patient.

Warning: some extensions are still under development, but it seems useful to provide them to allow upgrade to more people, and to allow user to give feedback to the authors.


More d'information

If you prefer to install PHP 8.0 beside the default PHP version, this can be achieved using the php80 prefixed packages, see the PHP 8.0 as Software Collection post.

You can also try the configuration wizard.

The packages available in the repository will be used as sources for Fedora 35 (if self contained change proposal is accepted).

By providing a full feature PHP stack, with about 130 available extensions, 7 PHP versions, as base and SCL packages, for Fedora and Enterprise Linux, and with 300 000 download per day, remi repository became in the last 15 years a reference for PHP users on RPM based distributions, maintained by an active contributor to the projects (Fedora, PHP, PECL...).
