Step 3: Install the MariaDB database server

Now that you have a web server up and running, you need to install a database system to be able to store and manage data for your site. We’ll install MariaDB, a community-developed fork of the original MySQL server by Oracle.

To install this software, run:

sudo dnf install mariadb-server mariadb

$ sudo vim /etc/php-fpm.d/www.conf

Scroll and locate the following lines:

user = apache
group = apache

Now change both values to Nginx.

user = nginx
group = nginx

Save and exit the configuration file. Then restart Nginx and php-fpm.

sudo systemctl restart nginx
sudo systemctl restart php-fpm

Step 5: Allow Ports in Firewalld

If your system has firewalld installed ans active, you need to allow Apache ports. This will allow network users to access web application from remote systems.

To see if it works, fire up your browser and browse the server’s address as shown

http://server-IP/info.php

If we don’t get to see the webpage, be sure to restart both PHP-FPM and Nginx and repeat the process.

sudo systemctl restart nginx php-fpm
