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 25

dnf install remi-release-25.rpm

Fedora 24

dnf install remi-release-24.rpm

RHEL version 7.2 or 7.3

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

RHEL version 6.8

rpm -Uvh remi-release-6.rpm epel-release-latest-6.noarch.rpm
rhn-channel --add --channel=rhel-$(uname -i)-server-optional-6

CentOS version 7.2 (or 7.3)

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

CentOS version 6.8

rpm -Uvh remi-release-6.rpm epel-release-latest-6.noarch.rpm


remi-php71 repository activation

Needed packages are in the remi-safe (enabled by default) and remi-php71 repositories, the latest is not enabled by default (administrator choice according to the desired PHP version).

RHEL or CentOS

yum install yum-utils
yum-config-manager --enable remi-php71


dnf install dnf-plugins-core
dnf config-manager --set-enabled remi-php71


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 7.1.0 (cli) (built: Dec  1 2016 06:23:20) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.1.0-dev, Copyright (c) 1998-2016 Zend Technologies
    with Zend OPcache v7.1.0, Copyright (c) 1999-2016, by Zend Technologies
    with Xdebug v2.5.0, Copyright (c) 2002-2016, by Derick Rethans


Known issues

The upgrade can fail (by design) when some installed extensions are not yet compatible with  PHP 7.

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 (memcache, redis...), 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 7 beside PHP 5, this can be achieve using the php71 prefixed packages, see the PHP 7.1 as Software Collection post.

You can also try the configuration wizard.

The packages available in the repository will be used as source for Fedora 26 (self contained change proposal already accepted).

By providing a full feature PHP stack, with about 150 available extensions, 4 PHP versions, as base and SCL packages, for Fedora and Enterprise Linux, and with 100 000 download per day, remi repository became in the last 10 years a reference for PHP users on RPM based distributions, maintained by an active contributor to the projects (Fedora, PHP, PECL...).
