Step 3: Install the MariaDB database server

MariaDB is a free and open-source database server that is a fork of MySQL. It became quite popular, especially after MySQL was acquired by Oracle. It ships with numerous features and optimizations such as better security and stability, additional storage engines, and overall better performance.

To install MariaDB on CentOS 8 by executing the following command on command line or terminal:

sudo dnf install mariadb-server mariadb

Once the installation is complete, start the database server as shown.

systemctl start mariadb

For best use, set MariaDB to start on boot using the command:

systemctl enable mariadb

Now, the default settings in MariaDB are quite weak and extra steps are required to harden the server. Therefore, run the script below to make additional tweaks to further secure your server.

Next,  configure  the PHP-FPM to  start on boot using the command:

$ sudo systemctl enable php-fpm

Next, proceed to edit the config file using this command

Usually, PHP-FPM is set to run as an Apache user. However, we have installed Nginx and we need to configure the user to Nginx. Therefore, proceed and open the /etc/php-fpm.d/www.conf. file:

$ 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: Test PHP

Execute the following command on command line or terminal to editing the root directory. And Create a sample PHP file as shown:

sudo vim  /usr/share/nginx/html/info.php

Add the following PHP code inside:

Save and close

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
