1. Obtain the installer script

   Download the installer script:

   # wget https://autoinstall.plesk.com/plesk-installer
   

   Enable execution mode for the downloaded installer script:

   # chmod +x ./plesk-installer
   

2. (Optional) During installation, Plesk configures firewalld, at which time runtime firewalld rules are lost. To preserve the currently configured firewalld runtime rules, execute the following command:

   # env PLESK_INSTALLER_SKIP_FIREWALLD=1
   

   However, in this case, you must manually open the ports required for Plesk to operate. You can do it via firewalld or the Plesk Firewall extension.

3. Make sure port 8447 is open

   Port 8447 is used for accessing the installer GUI. Make sure, this port is open.

4. Launch the installer with GUI

   Run the script with option --web-interface to launch the interactive installer with web interface for the latest stable Plesk version:

   # ./plesk-installer --web-interface
   

   

5. Access the installer GUI

   In your browser, go to the specified address:

   

   Use the ‘root’ user name and password.

   Login name: root
   Password: <YOUR_SERVER_ROOT_PASSWORD>
   

6. Choose to install a new product

   

   Click Install or Upgrade Product.

7. Select product version

   You will see the latest stable version of Plesk available for installing.

   

   If you run the installer script with option --all-versions, you will be able to choose what version of Plesk to install.

   # ./plesk-installer --web-interface --all-versions
   

   

   Click Continue.

8. Select packages to be installed with Plesk

   

   Select one of the available installation types. This will determine what packages will be installed with Plesk. Then click Continue to start the installation.

   Alternatively, you can personally select what packages will be installed. To do that, enable Preview components selection and then click Continue.

   

   Review and edit the list of packages for installing.

   

   Click Continue. The installation process will begin.

9. Installing

   

   You will be able to see the console output directly in the installer web interface. When everything is installed, you will be informed.

   

Besides installing Plesk, the installer web interface can also be used to add, remove and update components in the same manner.

To learn more about the installation script, run:
