Installation

This guide assume you have already acquired and installed a copy of MOH:AA on your server. If not, see Getting started.

Download the latest release that matches your server's platform.
Extract files from the archive into your MOH:AA directory

You can also use Docker, see Creating a Docker image.

Configuring the server

For a list of commonly used settings in the server.cfg file, see Server configuration.
For examples and new OpenMoHAA features (like setting up bots), see Game configuration

Starting the server

Run the omohaaded executable from your MOHAA directory. Use one of the following commands, depending on the game you want to use:

For Allied Assault:

./omohaaded +set com_target_game 0 +exec server_opm.cfg
For Spearhead:

./omohaaded +set com_target_game 1 +exec server_opm.cfg
For Breakthrough:

./omohaaded +set com_target_game 2 +exec server_opm.cfg
