Valheim Dedicated Server Setup Guide (Run a Server From Your PC)

Setting up your own Valheim dedicated server is one of the best ways to enjoy the game with friends. Instead of relying on one player to host the world, a dedicated server runs separately and keeps your world online even when the host is offline.

In this guide, you’ll learn how to complete a full Valheim dedicated server setup using the official Valheim Dedicated Server tool on Steam. We’ll walk through installing the server, configuring the startup settings, adding admins, and using common admin commands.

Even if you’ve never hosted a game server before, this guide will walk you through the process step-by-step.

What Is a Valheim Dedicated Server? #

A Valheim dedicated server is a standalone server application that runs separately from the normal Valheim game client.

Running a dedicated server allows:

• The world to stay online 24/7
• Players to join even when the host is offline
• Admin controls for moderation
• More stable multiplayer performance

Instead of launching a multiplayer world from inside the game, players connect directly to the dedicated server.

Requirements for Running a Valheim Server #

Before starting your Valheim dedicated server setup, make sure your PC meets these basic requirements.

Recommended Hardware

Small server (3–6 players)

• CPU: 4 cores recommended
• RAM: 4–8 GB
• Storage: 10+ GB
• Stable internet connection

For heavily modded servers or active communities, more RAM and CPU performance may be required.

Step 1: Install the Valheim Dedicated Server Tool #

The easiest way to run a server from your PC is by using the Valheim Dedicated Server tool included with Steam.

Install the Server

1. Open Steam
2. Go to your Library
3. Change the filter to Tools
4. Search for Valheim Dedicated Server
5. Click Install

Once installed, the server files will appear inside your Steam installation directory.

Typical location:

Steam/steamapps/common/Valheim dedicated server

Step 2: Configure Your Server Startup File #

Inside the server folder you will find the startup script:

start_headless_server.bat

This file controls how the server launches.

Open it with Notepad or another text editor and locate the launch command.

The correct launch format should look similar to this:

valheim_server -nographics -batchmode -name "My Server" -port 2456 -world "MyWorld" -password "secret" -public 1

What Each Setting Does

Server Name

The name that appears in the multiplayer server list.

-name "My Viking Server"

World Name

This is the name of the world the server loads.

-world "MyWorld"

If the world does not exist yet, Valheim will automatically create it.

Server Password

All Valheim servers require a password.

-password "StrongPass"

Password rules:

• Must be at least 5 characters
• Cannot contain spaces

Server Port

The default port used by Valheim is:

-port 2456

Normally this does not need to be changed.

Public Server Setting

Controls whether the server appears in the public server browser.

-public 1

• 1 = visible in public server list
• 0 = private server

Step 3: Start the Server #

After saving your configuration:

1. Double-click start_headless_server.bat
2. A console window will open
3. Wait for the server to finish loading

When you see Game server connected, the server is ready.

Step 4: Allow Players to Join #

Players can join your Valheim server using either the server list or direct IP.

Join Through the Server Browser

1. Launch Valheim
2. Click Join Game
3. Select Community Servers
4. Search for your server name

Join Using Direct IP

Players can connect directly using an IP address.

123.45.67.89:2456

Step 5: Open the Required Ports #

If players cannot connect, your router or firewall may be blocking the server ports.

Valheim requires the following ports:

2456
2457
2458

These ports must be open primarily for UDP traffic.

Typical usage:

• 2456 UDP – Main game port
• 2457 UDP – Server query port
• 2458 UDP – Additional networking port

Step 6: Add Server Admins #

Admins have permission to run moderation commands.

How to Add an Admin

1. Navigate to the server directory
2. Find the file:

adminlist.txt

1. Open it with a text editor
2. Add the player’s Steam64 ID

Example:

76561198012345678

1. Save the file
2. Restart the server

To find a Steam64 ID you can use:

https://steamid.io

Step 7: Using Valheim Admin Commands #

Admins can manage the server using console commands.

Open the Console

Press:

F5

Admins listed in adminlist.txt can run commands directly.

kick <name/ip/userID>

Want an Easier Option? #

Running a server from your own PC requires installing the server software, configuring startup scripts, opening network ports, and keeping your computer online whenever players want to join.

For small groups this setup can work well, but it also means:

• Your PC must stay powered on
• Your internet connection must remain stable
• Performance depends entirely on your local hardware
• Network issues or IP changes can interrupt the server

If you would prefer to skip the technical setup and maintenance, you can run your world on a dedicated Valheim server hosted by Academy Hosting. A hosted server keeps the world online 24/7 and removes the need for local configuration or port forwarding.

Our Valheim hosting includes:

• Instant server deployment
• High-performance hardware optimized for game servers
• Simple server management panel
• Mod support
• Automatic backups
• Reliable uptime

You can view our Valheim hosting plans here:

Players can then connect to the server the same way they would any other Valheim world, without needing the host computer to remain online.
