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

    Password: <YOUR_SERVER_ROOT_PASSWORD>
