Questions: How to Install PHP on CentOS 8 / RHEL 8?, how to install PHP 7.2 on CentOS 8 / RHEL 8?, How to install PHP 7.1 on CentOS 8 / RHEL 8?. Welcome to our guide on how to Install PHP 7.2/7.1 on CentOS 8 / RHEL 8. Red Hat Enterprise Linux 8 is distributed with PHP 7.2 unlike PHP 5.4 which was distributed in RHEL 7. Some of the most notable changes in PHP 7.2 are:

  • FastCGI Process Manager (FPM) is used by default. This is safe for use with a threaded http
  • When the max_execution_timeconfiguration variable is changed, its value should match the httpd ProxyTimeout setting
  • PHP script warning and errors are no longer logged to,/var/log/httpd/error.log they are now logged to the file/var/log/php-fpm/www-error.log.
  • The php-flag and php_value variables should be set in the pool configuration file /etc/php-fpm.d/*.conf. They are no longer configured in the httpd configuration files.
  • The user running PHP scripts is now configured in the FPM pool configuration file –  /etc/php-fpm/d/www.conf. The default user is apache.
  • Whenever you install a new extension or change PHP configuration file, you’ll need to restart the php-fpm service

Extensions removed on PHP 7.2

Below are the extensions that have been deprecated in PHP 7.2

  • memcache
  • zip
  • mysql (note that the mysqli and pdo_mysql extensions are still available, provided by php-mysqlnd package)
  • aspell

Both PHP 7.2 and PHP 7.1 should be available on the AppStream repository:

.td_uid_2_5d9063ec421e5_rand.td-a-rec-img{text-align:left}.td_uid_2_5d9063ec421e5_rand.td-a-rec-img img{margin:0 auto 0 0}
$ sudo yum repolist

You can confirm enabled and default PHP module by running the following command in your terminal.

$ sudo yum module list | grep php 
php 7.1 devel, minimal, default [d] PHP scripting language
php 7.2 [d][e] devel, minimal, default [d] [i] PHP scripting language

For the installation of PHP 7.3 on RHEL 8, check: How to Install PHP 7.3, PHP 7.3-FPM on RHEL 8

Install PHP 7.2 on RHEL 8 / CentOS 8

Install PHP 7.2 on RHEL 8 / CentOS 8 by running the command below

sudo yum module install php:7.2

The command above will install a number of PHP extensions as well required for different integrations.

After the installation is complete, check your PHP version using the following command:

$ php -v
PHP 7.2.11 (cli) (built: Oct 9 2018 15:09:36) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies

As seen in the output above, we have PHP 7.2.11 on our RHEL 8 system.

Start and Configure php-fpm service

Now activate php-fpm service

sudo systemctl enable --now php-fpm

Confirm service status

$ systemctl status php-fpm

sudo yum install php-<entension>

sudo yum -y install php php-cli php-fpm php-mysqlnd php-zip php-devel php-gd php-mbstring php-curl php-xml php-pear php-bcmath php-json

How to Install PHP 7.1 on RHEL 8

If you would like to install PHP 7.1, it is available on the AppStream repository as well. Install PHP 7.1 using the command below:

sudo yum module install php:7.1

Verify PHP version using:

$ php -v

You can easily switch back to PHP 7.2 using:

sudo yum module install php:7.2

Testing your PHP installation

Finally, let’s test to confirm that our PHP is working as expected. Install Apache HTTP Server using:

sudo yum module install httpd

Then Active the service

sudo systemctl enable --now httpd

Create a test PHP page

echo '<?php phpinfo();' >/var/www/html/info.php

Open the server URL:

Enable http port on the firewall

sudo firewall-cmd --add-service=http --permanent
sudo firewall-cmd --reload

In our next articles, we will cover the installation Nginx web server and configuring it to serve PHP web pages.
