Valheim Server Configuration

This guide covers the panel Startup settings, setting up admins, and managing worlds. For modding, see Mods.

Core Settings (Startup Tab)

Valheim's core settings live in the panel Startup tab, not in a config file. The important fields:

FieldWhat it does
Server NameShown in the Valheim community server list
World NameName of the world file, used as the save file name on disk
Server PasswordRequired. Must be at least 5 characters
PublicTrue to list on the community server browser, false for hidden
CrossplayEnable Xbox and cross-platform play

Save and restart for changes to take effect.

Admin Setup

Admins are configured in adminlist.txt at the server root. Edit it through the File Manager. Each line is one SteamID64:

Code
76561197960287930

Add one SteamID64 per line for each additional admin.

Restart the server after editing.

In-game, admins press F5 to open the chat console:

Code
help              Show all commands
ping              Ping the server
kick <name>       Kick a player
ban <name>        Ban a player
unban <name>      Remove a ban
save              Force save the world

Item spawning and teleporting require developer commands, which are restricted on dedicated servers by default. To unlock full admin capability, install the Server Devcommands mod (see Mods).

World Management

Worlds are stored in worlds_local/. Each world has two files:

  • MyWorld.db (the world data)
  • MyWorld.fwl (metadata)

To switch worlds, change the World Name in the Startup tab. If the world does not exist, Valheim generates a new one. If it does, Valheim loads it.

To wipe a world, stop the server, delete both files in worlds_local/, then start.

To upload an existing single-player world:

  1. Find your local files. On Windows: %USERPROFILE%\AppData\LocalLow\IronGate\Valheim\worlds_local\.
  2. Upload both the .db and .fwl files to worlds_local/ via SFTP.
  3. Set World Name in Startup to match (without the extension).
  4. Restart.
