Non-interactive, automatic, headless installs or upgrades

Passenger and Passenger Enterprise can be installed in a non-interactive, automatic, headless manner. This is perfect in automated scenarios, e.g. when using Chef or Puppet, or when building a Docker container.

This guide assumes that you are already familiar with installing Passenger manually. If not, please read the installation guide.

The instructions in this guide apply equally to the open source version and to the Enterprise version.
