1. Installing Plesk


To install Plesk software on a server,

  1. Download the Auto-installer utility that suits your operating system from and save it on your server's hard drive. Note: to avoid any issues please use the latest version of Auto-installer.
  2. Change your working directory to the directory where the Auto-installer utility resides, for instance:
    # cd /root/plesk
  3. Set the execution permission for Auto-installer:
    # chmod +x plesk_auto_installer_file_name
  4. Run the Auto-installer:
    # ./plesk_auto_installer_file_name
  5. Follow the instructions presented on the screen to complete the installation.
  6. When the installation is finished, Plesk will start automatically. Now, to complete the initial configuration, log in to the Plesk control panel running on your host at or https://IP-address:8443/.

    Use the username "admin" and password "setup" (both are case sensitive). For security reasons, be sure to change the password upon initial login.

2. Upgrading Plesk

Important notes for Virtuozzo users:

Since Plesk 8.1, Auto-installer (Plesk Updater) supports updating Plesk inside Virtuozzo virtual private servers (VPS) using EZ templates.

Compared to the previously used updating scheme, updating through EZ templates will save disk space significantly and will allow running more virtual private servers on a single hardware node.

This feature is available only with EZ templates. To upgrade a VPS with Plesk this way, you need to:

  1. Install on the hardware node the kernel 2.6.9-023stab033.7 and VZCTL 3.0.1-23 updates, or later.
  2. Install the vzaiproxy package on the hardware node. On the Plesk 8.1 release date, you can download this package from Afterwards, this package will be shipped with Virtuozzo updates.
  3. Install all EZ templates from Plesk distribution on the hardware node.

    Note: We recommend that you install or update using the EZ templates shipped with Plesk 8.1, so as to avoid subsequent manual installation of hotfixes and updates.

  4. Run Plesk installation or upgrade using Auto-installer Console Utility or Plesk Control Panel (Server->Updater). And then follow the instructions presented on the screen.

As for STD templates:

if you had Plesk 7.5.4 upgraded by the Auto-installer utility, but still wish to upgrade Plesk by upgrading Virtuozzo STD templates, use the "Jump Mode" option.

If Plesk upgrade fails, try running the "killall -9 safe_mysqld mysqld" command and then restart the upgrade procedure. After upgrading Plesk from version 7.x to 8.2, the Plesk Updater function in the control panel will be accessible. For subsequent upgrades, Virtuozzo users will need to either use the consol Auto-installer utility or unlock the control panel's Updater function. To do this, log in to Plesk's MySQL database server, type "use psa", and then run the query "update misc set val='false' where param='disable_updater';".

Notes on upgrading: After upgrading to Plesk 8.2, all custom (third-party) skins become unregistered. If you wish to restore the custom skins that you used before the upgrade, run the command "/opt/psa/tmp/", where /opt/psa is your Plesk installation directory (for example, /usr/local/psa.) You can remove this file after restoring your skins.

2.1 Upgrading Plesk from the Control Panel

To update or upgrade your Plesk software from the control panel:

  1. Log in to Plesk as administrator, and click the Server shortcut in the left-side navigation pane. The Server Administration screen opens.
  2. Click the Updater icon in the Services group. The control panel connects to the Plesk Update server, retrieves information on the available releases, then analyses the components installed in your system, and displays the lists of available releases and component updates. For each Plesk version released a brief description of available operations is displayed.

    Note: If you want to update/upgrade from a locally stored Plesk distribution or Plesk update server mirror inside your network, click Preferences, select the "Network storage" source type, specify the URL and click OK.

    Note: If you run Plesk inside a VPS, you can install updates using EZ templates.

    ATTENTION: To upgrade to Plesk 8.1 from previous versions you need to use upgrade through Auto-installer Console Utility because previous versions of Plesk uses an old version of Auto-installer which don't know about new distribution(via FreeBSD ports).

  3. Select the Plesk version that you want to update, or upgrade to. A list of available components appears.
  4. Select the checkboxes corresponding to the components you wish to install and click Install. A confirmation page appears.
  5. Specify your e-mail address. You will be sent a notice by e-mail once update is completed. To confirm installation of the selected components, select the checkbox and click OK. The components/updates you selected will be downloaded and automatically installed in the background mode.

2.2 Upgrading Plesk through the Auto-installer Console Utility

To update or upgrade your Plesk software by means of the Auto-installer utility:

  1. You need to obtain the Auto-installer utility version 3.1.0 or later. You can download it from

    Note: If you run Plesk inside a VPS, you can update Plesk using EZ templates.

  2. Run the 'psa_autoinstaller' binary file.
  3. The Auto-installer will detect your existing installation of Plesk and ask if you want to upgrade it. Read the Welcome page and press Enter.
  4. Specify the source of Plesk distribution package. You can choose to upgrade from a local media, the official Plesk update server, or another Internet site. Once you have selected the source, press Enter.
  5. Specify the proxy server settings, if applicable, press Enter to continue.
  6. Select the product version that you wish to upgrade to: type the number corresponding to the product name of your choice. Press Enter to continue.
  7. Auto-installer will list all components available for installation.

    See the related article on known problem with installation/upgrade through EZ templates.

  8. Auto-installer will estimate the amount of disk space required for installation of Plesk and will show you the amount of free disk space. If you have enough free disk space, press Enter.
  9. Auto-installer will show the information about the packages that will be installed. Press Enter to continue.
  10. Select the components that you wish to install or upgrade, then press Enter to continue. Once the required components are downloaded, your Plesk software will be upgraded.

Note: When upgrading Plesk from 7.5.x to 8.2 using Auto-installer, be sure to upgrade the Tomcat component, otherwise, Java applications will not be supported on your server.

3. Installing Plesk Manually from deb Packages

When the installation is finished, Plesk will start automatically. In order to complete the Plesk initial configuration, you need to log in to Plesk on your host at or https://IP-Address:8443/

The default username is "admin" and the default password is "setup", both are case sensitive. For security reasons, this password should be changed upon initial login.

NOTES: Plesk enables PHP safe_mode during installation (the directive 'safe_mode-On' in php.ini). However, you can disable the safe_mode for individual domains if required. To do this, you should use the vhost.conf (vhost_ssl.conf) features. See for details.

In order to use multiple interface languages in the Webmail application, you may need to run the 'dpkg-reconfigure locales' command and choose the locales to install.

Plesk cannot enable user quotas on XFS partition during installation because such operation requires remount of XFS partition. In order to enable hard disk quotas on XFS partition you should manually remount it with usrquota option (additional information can be found on 'quotaon' man page).

We recommend that you install the Turba contact management application, if you wish to have access to the contact list entries you had in your Horde 2 application before upgrade. To install Horde applications, use the command:

dpkg -i <deb-packages list>

For managing the SiteBuilder system through Plesk, the 'remote_admin' user account with administrator's privileges is created in the SiteBuilder. To ensure the proper work of the SiteBuilder Remote Administration module, you should not remove or block this user account. however, if you do not use the SiteBuilder Remote Administration Module, you can remove this user account.

To make operating the SiteBuilder API (remote_admin) more secure, the /usr/local/sitebuilder/remote_admin directory is password protected, and the following default user name and password are stored in the .htpasswd file: radmin/sbradmin. For security reasons you must change the default password. To do this, run the command 'htpasswd /usr/local/sitebuilder/remote_admin/.htpasswd radmin', and then enter the new password and confirm it.
