Install PHP 8.1 on Fedora 37/36/35/34/33/32

For normal PHP requirements, you can go with the latest version available on the default Fedora RPM repositories. For any version of PHP not in the default repos, you’ll be required to add third party repository such as REMI or build from source.

Step 1: Enable Remi repository on Fedora

Perform an update on your Fedora system

sudo dnf -y update

Then proceed to enable Remi repository on Fedora.

Fedora 37:

sudo dnf -y install http://rpms.remirepo.net/fedora/remi-release-37.rpm

Fedora 36:

sudo dnf -y install http://rpms.remirepo.net/fedora/remi-release-36.rpm

Fedora 35:

sudo dnf -y install http://rpms.remirepo.net/fedora/remi-release-35.rpm

Fedora 34:

sudo dnf -y install http://rpms.remirepo.net/fedora/remi-release-34.rpm

Fedora 33:

sudo dnf -y install http://rpms.remirepo.net/fedora/remi-release-33.rpm

Step 2: Install PHP 8.1 on Fedora

After addition of REMI repository, disable default AppStream PHP module.

sudo dnf -y module reset php

Enable php:remi-8.1 module

sudo dnf -y install dnf-plugins-core
sudo dnf config-manager --set-enabled remi
sudo dnf -y module install php:remi-8.1

Check installed version of PHP on your Fedora Linux:

$ php --version
PHP 8.1.14 (cli) (built: Jan  4 2023 06:45:14) (NTS gcc x86_64)
Copyright (c) The PHP Group
Zend Engine v4.1.14, Copyright (c) Zend Technologies

Installing multiple versions of PHP

If you’re interested in having multiple versions of PHP on your Fedora system, then install from php81 collection which is available in the remi-safe repository and can be installed with the command:

sudo dnf install php81

Additional PHP extensions can then be installed using the command:

sudo dnf install php81-php-xxx

To check the version of PHP 8.1 installed using this method, run:

$ php81 --version
PHP 8.1.14 (cli) (built: Jan  4 2023 06:45:14) (NTS gcc x86_64)
Copyright (c) The PHP Group
Zend Engine v4.1.14, Copyright (c) Zend Technologies
    with Zend OPcache v8.1.14, Copyright (c), by Zend Technologies

Step 3:Install PHP 8.1 extensions on Fedora

Install PHP extensions using the name format php-<extension>.

sudo dnf install php-<extension>

Here is an example to install mostly used extensions of PHP:

sudo dnf install php-{cli,fpm,mysqlnd,zip,devel,gd,mcrypt,mbstring,curl,xml,pear,bcmath,json,opcache}

Step 4: Use PHP-FPM on Nginx / Apache httpd

The default PHP configuration file is /etc/php.ini.

sudo cat /etc/php.ini

For Nginx web server, use PHP-FPM (FastCGI Process Manager) configuration file to set CGI settings:

sudo vim /etc/php-fpm.d/www.conf

Once your PHP and PHP-FPM settings are modified, nginx and httpd web server services can be restarted.

# Nginx
sudo systemctl enable --now php-fpm
sudo systemctl restart nginx

# Apache
sudo systemctl enable --now php-fpm
sudo systemctl restart httpd

You should now have PHP 8.1 installed on Fedora Linux system. Enjoy PHP Development and have an amazing Code time.
