LAMP is the classic stack for PHP websites: Linux, the Apache web server, a MySQL-compatible database and PHP. It runs WordPress, Drupal, Joomla, Laravel and most other PHP applications.
The VPS.org one-click install uses Ubuntu 22.04 and installs Apache with mod_php, MariaDB and PHP with the common extensions (curl, gd, mbstring, xml, zip, mysql). It sets a random MariaDB root password, removes the anonymous database users and the test database, enables mod_rewrite, and places a placeholder page plus a phpinfo page in /var/www/html.
After the install, delete /var/www/html/info.php, point your domain at the server, and add a free Let's Encrypt certificate with Certbot. Firewall rules and backups are yours to configure.
