Multi-instance Factorio servers under systemd.

Factorio systemd Support

This repository contains files needed to set up multi-instance Factorio servers running under systemd.

Quickstart

1. Clone:

   $ git clone https://github.com/oko/factorio-systemd
   

2. Install files:

   $ cd factorio-systemd
   $ sudo make install
   

3. Initialize a Factorio game:

   $ sudo factorio-init myserver
   <...various script output...>
   Next steps:
     1. Edit /etc/factorio/test2/config.ini to tweak server network config
     2. Edit /etc/factorio/test2/server-settings.json to tweak server game config
     3. Edit /etc/factorio/test2/map-gen-settings.json to tweak server mapgen config
     4. Enable server with 'systemctl start factorio@test2'
     5. Start server with 'systemctl start factorio@test2'
   

4. Tweak configuration and enable/start the server as explained by factorio-init

5. If you need to reset the game, use factorio-reset (which stops the server, removes the game file, and restarts the server to let factorio-init@$instance.service recreate it)

How Factorio Runs

Each instance $instance runs under its own systemd service named factorio@$instance.service, in the following environment:

1. Each instance has its own config directory under /etc/factorio/$instance
2. Each instance has its own data directory under /var/lib/factorio/$instance
3. All instances run as the factorio user (created automatically by factorio-init@$instance.service if necessary)
4. All instances run sandboxed with ProtectSystem=strict and ProtectHome=yes
5. All instances run with read-write access to their own data directory only
