In this tutorial, we will show you how to install and configuration of PHP 7.4 on CentOS 8. For those of you who didn’t know, PHP (PHP: Hypertext Preprocessor) is a server-side scripting language designed for web development but also used as a general-purpose programming language. PHP code is interpreted by a web server with a PHP processor module, which generates the resulting web page: PHP commands can be embedded directly into an HTML source document rather than calling an external file to process data.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you the step-by-step installation of PHP 7.4 on the CentOS 8 server.

Prerequisites

• A server running one of the following operating systems: CentOS 8.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install PHP 7.4 on CentOS 8

Step 1. First, let’s start by ensuring your system is up-to-date.

sudo dnf update

Step 2. Add EPEL and Remi Repositories.

You need to enable Remi and EPEL yum repositories on your system:

sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm

Step 2. Installing PHP 7.4 on CentOS 8.

Now, enable php:remi-7.4 module to install PHP using the following command:

sudo dnf module enable php:remi-7.4

Once the PHP Remi-7.4 module has been enabled, you can then proceed and install PHP using the command below:

sudo dnf install php php-cli php-common

Step 3. Verify Install PHP version.

Once it is completed, you can ensure that the latest stable release of PHP 7.4 is installed on your system by using the command:

# php -v

PHP 7.4 ORC5 (cli) (built: Nov 12 2019 09:35:18) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.10, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.3.10, Copyright (c) 1999-2018, by Zend Technologies

To test PHP, create a test file named info.php with the content below. Save the file, then browse to it to see if PHP is working:

nano /var/www/html/info.php

<?php
phpinfo();
?>
