dnf install mariadb-server

Enable MariaDB to start on boot
systemctl enable mariadb

Start MariaDB
systemctl start mariadb

CentOS 8 come with MariaDB 10.3. By default there is no root PW set, So you can connect to MySQL with command "mysql".

To create a database, use
create database DB_NAME_HERE;

To create a user, run
grant all on DB_NAME_HERE.* to 'USER_NAME'@'localhost' identified by 'PASSWORD_HERE';

Now you have Apache, PHP, MySQL ready to use. Upload your web application to /var/www/html folder using SFTP.
