Install and Manage PHP Packages on CentOS

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

 Package                      Architecture     Version
 php                          x86_64           7.2.11-2.module_el8.1.0

 php-common                   x86_64           7.2.11-2.module_el8.1.0
Installing weak dependencies:
 apr-util-bdb                 x86_64           1.6.1-6.el8
 apr-util-openssl             x86_64           1.6.1-6.el8
 php-fpm                      x86_64           7.2.11-2.module_el8.1.0
Enabling module streams:
 httpd                                         2.4
 nginx                                         1.14
 php                                           7.2



3. Verify the "php" package:

herong$ php -version

PHP 7.2.11 (cli) (built: Oct  9 2018 15:09:36) ( NTS )

Cool! I have installed the "php" 7.2 package on my CentOS computer without any issues.
