Plesk is a proprietary web host control panel that allows users to administer their personal and/or client's websites, databases, email and domains. It allows for easy point and click administration/maintenance through a browser.
Plesk must be installed on a new Debian 8 (Jessie) install without any changes. Failure to adhere to this could result in a borked Debian and/or Plesk install.
Log in as a regular user who has permission to use the sudo command. Enter the following commands below to start installation of Plesk. You must assign the actual domain name to your instance in order for the install to complete. Replace firstname.lastname@example.org with your actual email address.
hostname example.com sudo sh -c "wget http://installer.plesk.com/plesk-installer -O - | sh /dev/stdin --source http://installer.plesk.com/ --target /tmp/plesk-installation --select-product-id plesk --select-release-latest --installation-type "Typical" --notify-email email@example.com"
The script should take about 10 minutes on a 1CPU instance to set up. Once complete, you should receive a message on the console that the Plesk installation has finished.
Enter the URL given in the console in your browser and you will be presented with the Plesk admin interface. Enter the information asked for such as type of installation, domain name, admin login/password and the Plesk license key to complete the install.
