Once you have completed the steps described in the section Before Installing Plesk, you can proceed directly to the Plesk installation.
To install Plesk on Linux or Windows-based servers, use the Plesk Installer utility. The Plesk Installer utility is available for download from http://installer.plesk.com/plesk-installer (for Linux) and http://autoinstall-win.plesk.com/plesk-installer.exe (for Windows).
Plesk Installer can be used either via a browser-based user interface or the command line.
Once the installation is finished, complete the post-installation setup. This includes Plesk initialization and installation of a license key. See the section After Installing Plesk for details.
