Different versions of Drupal can be installed by scripts that are available on the box.
To install Drupal 7 you need to run the /var/www/drupal7_install.sh script. This will download the latest version of Drupal 7 and install it into the MySQL database available on Vlad using the "Standard" installation profile. The Overlay module is also uninstalled automatically.
To install Drupal 8 you need to run the /var/www/drupal8_install.sh script. This will pull the latest version of Drupal 8 from the Drupal git repository and install it into the MySQL database available on Vlad.
User 1's login details for each of these Drupal install scripts is as follows:
Username: admin Password: password
NOTE: Both of these scripts will remove anything already in the /var/www/sites/docroot directory (or whatever name you have selected for it) so be careful.
Vlad comes with both Drush 6 (current) and Drush 7 (dev) versions. This means you can run Drush commands against a Drupal 8 install.
To run the current version of Drush just using the drush command as you normally would.
To run the dev version of Drush you need to use either the
drush7 alias in the same way as you would normally run Drush.
