Setting Up a Valheim Dedicated Server on Linux

Getting valheim right from the start saves hours of debugging later. In this comprehensive guide, we'll cover everything from initial setup to production-ready configuration, including dedicated and linux considerations.

Server Installation

It's recommended to test this configuration in a staging environment before deploying to production. This helps identify potential compatibility issues and allows you to benchmark performance differences.

# Create a dedicated game server user
sudo useradd -m -s /bin/bash gameserver
sudo su - gameserver

# Install SteamCMD
mkdir -p ~/steamcmd && cd ~/steamcmd
curl -sqL "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz" | tar zxvf -

# Install the game server
./steamcmd.sh +force_install_dir ~/servers/valheim +login anonymous +app_update 1234567 validate +quit

The output should show the service running without errors. If you see any warning messages, address them before proceeding to the next step.

Configuration File Setup

It's recommended to test this configuration in a staging environment before deploying to production. This helps identify potential compatibility issues and allows you to benchmark performance differences.

# Server configuration file
[Server]
ServerName=My valheim Server
MaxPlayers=32
ServerPort=27015
Password=
AdminPassword=changeme
SaveInterval=300

Make sure to restart the service after applying these changes. Some settings require a full restart rather than a reload to take effect.

• Keep all software components up to date
• Set up fail2ban for brute force protection
• Use SSH keys instead of password authentication

Common Issues and Solutions

• High memory usage: Review the configuration for memory-related settings. Reduce worker counts or buffer sizes if running on a low-RAM VPS.
• Permission denied errors: Ensure files and directories have the correct ownership. Use chown -R to fix ownership and chmod for permissions.
• Service won't start: Check the logs with journalctl -xe -u valheim. Common causes include port conflicts, missing configuration files, or insufficient permissions.

Summary

You've successfully configured valheim on your VPS. Remember to monitor performance, keep your software updated, and maintain regular backups. If you run into issues, consult the official documentation or open a support ticket for assistance.
