Set up a Valheim dedicated server on Linux

Install HaruHost

On Ubuntu (x86-64), run:

curl -fsSL https://haruhost.com/install.sh | sudo bash

HaruHost installs as a service. Sign in with the QR code it shows in your SSH session, then open the web panel from any browser.

What HaruHost does for you

• Docker: on Ubuntu, HaruHost installs and sets up Docker with one click when you create your first server.
• SteamCMD and libraries: not needed. HaruHost downloads the Valheim dedicated server and everything it needs to run.
• systemd and screen: not needed. HaruHost runs as a service and keeps the server running without an open SSH session.
• Getting friends in: with the Tunnel, friends join with Join IP and the Server Address, with no port forwarding; or every server gets its ports from your port range.
• Settings: the server's Auto Config page sets the server name, world, password, public listing, crossplay and world modifiers, as on Windows. An existing server on Manual Config keeps it until you switch it to Auto Config.
• Players and chat: who is online, admin, kick and ban, chat logs and Discord chat work on Linux as on Windows.

Step by step

1. Run the install command and sign in.
2. In the web panel, choose Add → New game server, pick your Linux server, then Valheim.
3. On the Connection step, choose Tunnel, or Ports to use the server's own address.
4. Create the server. If Docker isn't installed yet, HaruHost asks first; press Install, then Create Server.
5. Open the server's Auto Config page and set the world, password, crossplay and world modifiers.
6. Start the server and send friends the Server Address and password from the Details tab.

Crossplay and world modifiers

Turn on Enable Crossplay and pick a World Modifier Preset on the server's Auto Config page, as on Windows. They apply at the next start.

Open the ports

With the Tunnel, nothing needs to be opened. With Ports, open your port range for UDP in your VPS provider's firewall; HaruHost shows it under Devices → Manage device → Network Settings.
