Install and Manage PHP Packages on CentOS

This section provides a tutorial example on how to install PHP 7.2 on CentOS 8 systems using 'dnf/yum' as the package manager.

If you want to run PHP scripts on CentOS Linux systems, you can follow what I did on my CentOS 8 computer:

1. Login as "herong", who has admin privileges.

2. Run "dnf search" to find available PHP packages. I see "php" and some PHP modules available for installation:

herong$ dnf search php

php.x86_64 : PHP scripting language for creating dynamic web sites
php-common.x86_64 : Common files for PHP
php-fpm.x86_64 : PHP FastCGI Process Manager
php-dbg.x86_64 : The interactive PHP debugger
php-cli.x86_64 : Command-line interface for PHP
php-xml.x86_64 : A module for PHP applications which use XML
php-json.x86_64 : JavaScript Object Notation extension for PHP
...

3. Install the "php" package:

herong$ sudo dnf install php
