Connect
Copy the address from the Connect card on the Overview page. In Factorio, choose Multiplayer > Connect to address and paste the address with its port.
To appear in the public game list, enter your Server Username and Server Token from your factorio.com profile in Settings > Startup.
Upload a save
- Stop the server on the Console page and take a backup on the Backups page.
- On the Files page, upload your save
.zipto thesavesfolder. Do not unzip it. Saves on your computer are usually in%appdata%\Factorio\saves. - Set Save Name in Settings > Startup to the file name, without
.zip. - Start the server.
Your server version must be able to open the save. You can set it with Factorio Version in Settings > Startup.
Install mods
Upload mods as .zip files to the mods folder, without unzipping them. Switch them on in mods/mod-list.json, and restart.
The server and every player need exactly the same mods and versions. Space Age, Quality and Elevated Rails are switched on in the same file.
Make yourself an admin
With the server running, type this on the Console page, using your Factorio name:
/promote YourName
To remove admin, use /demote YourName.
Where the settings are
-
Settings > Startup: server name, description, save name, autosave interval, autosave slots, AFK kick and version. These are written into
data/server-settings.jsonevery time the server starts, so change them in Startup rather than in the file. -
data/server-settings.json: other options, such as the join password and who can pause the game. Edit it while the server is stopped. -
data/map-settings.jsonanddata/map-gen-settings.json: used when a new map is created. To get a new map, use a new Save Name. - Backups: take a copy before changing mods or versions.
