Rename file to match version (1.1.87 in this example)

$ sudo mv linux64 factorio-headless_linux_2.0.60.tar.xz

Extract archived and zipped file

$ sudo tar -xJf factorio-headless_linux_2.0.60.tar.xz
$ ls -l

Remove file (save space, you can always download the file again, if needed)

robot01@apu01:/opt$ sudo rm factorio-headless_linux_2.0.60.tar.xz

Add a new user to run factorio and assign ownership of /opt/factorio directory to same user

$ sudo useradd factorio
$ sudo chown -R factorio:factorio /opt/factorio/

Verify permissions show factorio for both user and group with ls -ld /opt/factorio

$ ls -ld /opt/factorio/
drwxr-xr-x 4 factorio factorio 4096 May  4 17:07 /opt/factorio/

Test Factorio binary by switching to factorio user then start server

robot01@apu01:/opt$ sudo su - factorio
No directory, logging in with HOME=/
$

As factorio user create /opt/factorio/ saves directory. I used saves directory.

$ mkdir /opt/factorio/saves

Start server and look for something like "File /savename does not exist."

$ /opt/factorio/bin/x64/factorio --start-server savename

At this point you can load up saved games or create some games.

Publish game on Factorio matching server

Copy /opt/factorio/data/server-settings.example.json to /opt/factorio/data/server-settings.json.

$ sudo cp /opt/factorio/data/server-settings.example.json /opt/factorio/data/server-settings.json

Edit appropriate server-settings.json values.

I used _comment_token versus password value. The appropriate value is located in %appdata%\Factorio\player-data.json under the key name "service-token". The service-token is populated after you've browsed the multiplayer servers via your Factorio game client.

My player-data.json for user "anon" on Windows was located at C:\Users\anon\AppData\Roaming\Factorio.

Make any changes to config ini

robot01@apu01:/opt/factorio$ sudo vi /opt/factorio/config/config.ini

Update headless server

download latest headless version

unzip and untar

sudo tar -xJf linux64

change permissions to your dedicated factorio user

sudo chown -R factorio:factorio factorio

launch game, example with saved game called "spoon.zip":

/opt/factorio/bin/x64/factorio --start-server /opt/factorio/saves/spoon.zip

Updating Factorio

1. Download the latest copy of the headless server using the steps above.
2. Move and rename the headless server following the steps above.
3. Assign ownership of /opt/factorio directory to factorio user used above.
