Valheim's open world and cooperative gameplay shine brightest when shared with friends. Setting up your own dedicated server allows for persistent worlds, customized settings, and uninterrupted adventures with your Viking crew. This comprehensive guide will walk you through the entire process, from choosing your hosting method to configuring advanced server settings.
Choosing Your Hosting Method: Local vs. Remote
The first crucial decision is where your server will reside: on your own machine (local) or a remote server.
Local Server:
- Pros: Simple setup, direct control, no additional costs (besides your existing internet and hardware). Ideal for small groups playing regularly from the same network.
- Cons: Your computer must remain on for the server to run. Performance can be affected by your computer's resources. Inaccessible to players outside your local network unless port forwarding is configured (more complex).
Remote Server:
- Pros: Accessible from anywhere with an internet connection. Runs consistently even when your computer is off. Better performance, especially for larger groups or modded servers.
- Cons: Requires a paid subscription from a hosting provider. You relinquish some direct control over the server's hardware and environment.
Setting Up a Local Valheim Server
This method is best suited for small, local groups.
Step 1: Install Valheim Dedicated Server:
Download the dedicated server from the official Valheim website. Extract the contents to a convenient location on your computer.
Step 2: Run the Server:
Navigate to the extracted folder in your command prompt or terminal. Execute the server executable (usually start_headless_server.bat on Windows or start_headless_server.sh on Linux/macOS). You'll be prompted to accept the EULA (End-User License Agreement).
Step 3: Configure the Server (serversettings.json):
The serversettings.json file dictates your server's settings. You can adjust parameters like world size, difficulty, player count, and more. Consult the Valheim Wiki for a complete list of configuration options. Important settings to consider include:
worldname: The name of your Valheim world.serverName: The name displayed on the server list.maxPlayers: The maximum number of players allowed on the server.worldSeed: A numerical seed for world generation (optional).
Step 4: Port Forwarding (for external access):
If you want players outside your local network to join, you'll need to configure port forwarding on your router. This involves assigning your computer a static IP address and forwarding UDP port 2456 to your computer. The specific steps depend on your router model; consult your router's documentation for instructions.
Setting Up a Remote Valheim Server (using a hosting provider)
For broader accessibility and better performance, a remote server is recommended.
Step 1: Choose a Hosting Provider:
Several providers offer Valheim server hosting. Research providers and compare pricing, features (like backups and support), and server locations to find one that fits your needs. Consider factors like server specifications (RAM, CPU), storage space, and the provider's reputation.
Step 2: Create a Server:
Once you've selected a provider, create a new Valheim server through their control panel. You'll typically choose a server location, select a server plan (based on the desired specs), and provide a password.
Step 3: Configure Server Settings:
Many hosting providers offer a graphical interface to adjust your server's settings, simplifying the process compared to editing the serversettings.json file directly. You can modify the same settings mentioned earlier (world name, max players, etc.).
Step 4: Connect to Your Server:
Once the server is running, you and your friends can join by entering the server IP address provided by your hosting provider into the Valheim server browser.
Troubleshooting and Additional Tips
- Server Crashes: Regularly check your server logs for error messages to diagnose crashes. Insufficient server resources (RAM) are a common cause.
- Modded Servers: Adding mods requires careful consideration. Ensure all players have the same mods installed and that the mods are compatible with your server version.
- Backups: Regularly back up your server's world to prevent data loss. Most hosting providers offer backup features; if self-hosting, create manual backups of the
worldfolder. - Server Performance: Optimize server settings for your player count and hardware. Experiment with different settings to find the best balance between performance and gameplay experience.
By following these steps, you can successfully set up a Valheim server and embark on epic adventures with your friends. Remember to choose the hosting method that best suits your needs and budget, and always consult the Valheim Wiki and your hosting provider's documentation for more detailed information. Happy raiding!
