How to Install PHP 7.4 and 8.1 in AlmaLinux 9

On AlmaLinux 9, PHP 8.1 packages are not available in the default OS AppStream repositories. By default, the version of PHP available on our AlmaLinux to install is PHP 8.0, so to get the newer versions such as PHP 8.1, we need to add/enable third-party repositories such as Remi.

To install PHP 8.1, we’ll need to add/enable the Remi RPM repositories which contain the PHP 8.1 packages that we need.

Pre-requisites :

  • A system with AlmaLinux 9 installed and running.

  • root access to the system.

First, let’s start by ensuring your system is up-to-date.

dnf update

Installing the EPEL and Remi Repository

For this, we use the PHP 7.4 and 8.1 packaged by Remi,

First, let us install the EPEL repository,

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm

Next, install the Remi repository with the following command,

dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm

Output:

[root@server ~]#  dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm
