The most common way of installing and upgrading Parallels Plesk Panel is to use the Parallels Installer utility. This utility connects to the Parallels Updates server where the Panel distribution packages are stored. It then retrieves, downloads, and installs Panel. You can download the Parallels Installer utility from http://www.parallels.com/eu/download/plesk/products/.
For detailed instructions on how to use Parallels Installer, refer to Parallels Plesk Panel 10.3 Installation and Upgrade Guide.
For Linux servers, there is another tool to install Panel - the one-click installer utility. This allows the latest version of Panel for your operating system and platform to be installed in one step. For detailed instructions on how to use the Parallels Installer and one-click installer utilities, refer to Parallels Plesk Panel 10.3 Installation and Upgrade Guide.
Installing Panel in the Parallels Virtuozzo Containers Environment
If you operate in the Parallels Virtuozzo Containers (PVC) environment, you can use application templates for installing Panel on containers.
When the application templates are installed on a PVC hardware node, they allow you to easily deploy the application on as many containers as required, saving system resources such as disk space.
You can obtain the Panel templates at http://www.parallels.com/eu/download/plesk/products/ or download them using the PVC command line utility call vzup2date -z (available on PVC 4 and above).
For more information on installing Panel on PVC, read the Parallels Plesk Panel Deployment Guide, chapter Deployment Inside Parallels Virtuozzo Containers.
