To get started with a simple LAMP stack on your VPS, do the following:
(for Ubuntu/Debian/CentOS):
Run sudo apt install apache2 mysql-server php php-mysql (Ubuntu/Debian) or yum install httpd mariadb-server php php-mysql (CentOS).
Then start services with systemctl start commands and secure MySQL by using the mysql_secure_installation command.
Finally place your files in /var/www/html.
