KeyHelp Installation

To install KeyHelp, it is enough to call a single command. After that, the wizard will guide you through the installation. During the installation, all the necessary services will be installed and configured, so you don't have to worry about anything else. After the installation is complete, you can immediately start administering your server.


System requirements

  • Operating system: Ubuntu LTS or Debian
  • Memory: At least 1 GB RAM
  • Architecture: 64-bit operating system (amd64 or arm64)
  • Installation must be performed on a clean system (minimal image), free of installed / configured software. All required services are installed and configured by KeyHelp.
  • The installation must be performed as root user.


Installing KeyHelp

  1. Connect to your server via SSH as root user.
  2. Run the following command from the command line.

    wget https://install.keyhelp.de/get_keyhelp.php -O install_keyhelp.sh ;
bash install_keyhelp.sh ;
  3. The installation is now being prepared and the installation wizard is started.
    The wizard allows you to adjust various installation parameters.
  4. Confirm the start of the installation via the Start installation menu item.
  5. After the installation is finished, your system will be restarted.

Now all the work has been completed and you can start administrating your KeyHelp server.

The login credentials for your primary administrator and database account can be found in the /root/keyhelp_login_data_* file.

If you receive the message ERROR: The certificate of 'install.keyhelp.de' is not trusted. you have several options to solve the problem:

- Add the --no-check-certificate parameter to the wget command.
- Install the ca-certificates package with the apt install ca-certificates command.
- Run the apt update && apt upgrade command.

KeyHelp does not provide an uninstaller.
If you want to remove KeyHelp and the services configured during the installation, you must manually reset your server.
