The Isle Evrima Dedicated Server Setup: SteamCMD, Linux & Config

The Isle Guide • Updated Aug 31, 2026

The Isle Evrima Dedicated Server Setup

The Isle has two server worlds that players commonly confuse: the old Legacy branch and the actively developed Evrima branch. A correct install is therefore more than downloading the files; the server, client, configuration, EOS identity, and ports all have to agree.

Install the Evrima server branch

The configuration step below is the one most setups get wrong. The The Isle Game.ini generator produces a working file with both section headers and one AllowedClasses line per dinosaur, which is the format Evrima actually reads.

The dedicated-server Steam app is 412680. A self-hosted SteamCMD install should explicitly select the Evrima beta rather than relying on whatever branch was last used:

steamcmd +force_install_dir /srv/theisle \
  +login anonymous \
  +app_update 412680 -beta evrima validate \
  +quit

After a patch, run the same update command again. The player client also needs the evrima beta; a Legacy client will not see an Evrima server. See the server-not-showing guide if the install succeeds but the browser is empty.

Create the two configuration files

FileLinux pathPurpose
Game.iniTheIsle/Saved/Config/LinuxServer/Game.iniServer name, slots, map, password, AI, RCON and gameplay rules.
Engine.iniTheIsle/Saved/Config/LinuxServer/Engine.iniEngine and Epic Online Services settings used during startup.
Engine logTheIsle/Saved/Logs/TheIsle.logRegistration, configuration and startup errors.

The EOS block belongs in Engine.ini. Treat its client ID and secret as credentials: never paste real values into a public guide, repository, Discord message or support ticket.

First-boot checklist

  1. Start the server once and wait for Game.ini, Engine.ini and the Saved tree to exist.
  2. Set the server name and a conservative slot count before inviting players.
  3. Confirm the assigned game and query ports are allowed by the firewall.
  4. Read TheIsle.log for EOS registration and listening errors, not only the wrapper's stdout.
  5. Join from an Evrima client using the server browser, then test direct IP as a second path.
Using Supercraft? The install, native Linux launcher, branch selection, ports, updates and backups are managed for you. Use the panel's displayed connection ports instead of copying Windows or default-port examples from a self-hosting tutorial.

If you are weighing that maintenance work against renting, see The Isle server hosting vs self-hosting comparison.

For a managed server with the setup work already handled, see The Isle server hosting.
