Setup Master Server - Guad/GTACoop GitHub Wiki
To set up your own GTA Coop master server, you need to download the the latest MasterServer.zip and extract it where ever you want.
sudo apt-get install wget;sudo apt-get install unzip;wget "https://github.com/Bluscream/GTACoop/releases/download/0.9.3-versionchanger/MasterServer.zip";unzip MasterServer.zip;sudo chmod +x install.sh;./install.sh
You also have to set up a proxy tunnel, cause the server is only listening to localhost. We included example config files for apache2 and nginx for you in the zip :)
You can start it later on by running ./start.sh
