Introduction

The PHP programming language is one of the most widely used server-side programming languages. It is a language used to develop dynamic and responsive websites.

In this guide, we will show how to install PHP 8.3 on AlmaLinux 8 and 9 versions. However, you can apply this tutorial to any other PHP version.

Installation guide

Step for AlmaLinux 8 only: Import GPG key repository

This step is for AlmaLinux 8 only. Skip this step on CentOS 7.

Run the following command to install updated GPG keys on AlmaLinux 8:

rpm --import https://repo.almalinux.org/almalinux/RPM-GPG-KEY-AlmaLinux

1. Update the system

Make sure to check if there are any updates available:

dnf check-update

If yes, run the following command to update the system:

yum update -y

After that, reboot the system:

reboot

2. Add remi RPM repository

For PHP, we also need to install EPEL.

On AlmaLinux 8 follow these steps:

Run the following command

dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

Install the remi repository:

dnf -y install http://rpms.remirepo.net/enterprise/remi-release-8.rpm

The same procedure is for AlmaLinux 9, just run these commands:

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

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

After that, update DNF cache with the following command:

dnf makecache -y

3. Reset default PHP module

Before installing PHP, make sure to reset the default PHP module by running this command:

dnf module reset php -y

4. Install the PHP

To install PHP, run the following command (you can install any other version; just type a different number instead of 8.3):

dnf module install php:remi-8.3

After that run this command to complete the installation:

dnf -y install php

5. Check PHP

To check if PHP was installed successfully, you can run this command, which will provide information about the installed version:

php -v

PHP extensions

To list all the available PHP extensions, run the following command:

php -m

To install the PHP extension, you need to run the dnf install command in the following format (change the "extension_name" to the actual extension):

dnf install php-extension_name

To install multiple extensions, run this command in the following format:

dnf install php-{common,pear,cgi,curl,mbstring,gd,mysqlnd,gettext,bcmath,json,xml,fpm,intl,zip,imap}
