Choosing the Right VPS for Valheim Server Hosting

Setting up a dedicated server for Valheim can greatly enhance your gaming experience by offering improved performance and control. Selecting the right VPS (Virtual Private Server) is crucial to ensure smooth gameplay and optimal server performance. Here are some key factors to consider when choosing a VPS for Valheim server hosting:

1. Server Specifications

CPU: Opt for a VPS with a powerful CPU, ideally with multiple cores, to handle the game’s processing demands efficiently.
RAM: A minimum of 4GB RAM is recommended for a Valheim server, but more RAM can support additional players and improve performance.
Storage: SSD storage is preferred for faster data retrieval and smoother gameplay. Ensure adequate space for game files and future updates.

2. Bandwidth and Network Speed

Bandwidth: Unlimited bandwidth is ideal to accommodate multiple players and prevent lag during peak times.
Network Speed: Look for a VPS with high network speed, at least 1 Gbps, to ensure low latency and quick data transfer.

3. Operating System Compatibility

Ensure the VPS supports the operating system you are comfortable with. Valheim servers can run on both Windows and Linux, but Linux is often preferred for its stability and lower resource usage.

4. Scalability

Choose a VPS provider that allows easy scalability. As your server grows, you may need to upgrade resources to accommodate more players or additional game mods.

5. Technical Support

Reliable technical support is essential. Ensure your VPS provider offers 24/7 support to assist with any technical issues or server management needs.

By carefully considering these factors, you can select the right VPS for your Valheim server hosting, ensuring a seamless and enjoyable gaming experience.

Installing SteamCMD on Your VPS

Setting up a Valheim dedicated server requires SteamCMD, a command-line tool used to install and update games hosted on a server. Follow these steps to install SteamCMD on your VPS:

Step 1: Update Your System

Before installing any new software, ensure your VPS is up-to-date. Run the following commands:


sudo apt update
sudo apt upgrade

Step 2: Install Required Dependencies

SteamCMD requires certain dependencies to function correctly. Install them using the following command:

If you need this service, Rackset’s team provides professional Minecraft server with full support so you can rely on the quality and get set up quickly.


sudo apt install lib32gcc-s1

Step 3: Create a SteamCMD Directory

It’s a good practice to create a dedicated directory for SteamCMD. This keeps your file structure organized:


mkdir ~/steamcmd
cd ~/steamcmd

Step 4: Download and Install SteamCMD

Download the SteamCMD package from Valve’s official server and extract it:


wget https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz
tar -xvzf steamcmd_linux.tar.gz

Step 5: Run SteamCMD

With SteamCMD installed, run it to ensure it updates to the latest version:


./steamcmd.sh

SteamCMD will start updating itself and prepare for further commands. Once the update is complete, you can proceed to use SteamCMD to install Valheim or any other game server.

Troubleshooting

If you encounter issues with missing libraries, ensure all dependencies are installed.
Check your network connection if the download fails.
Ensure you have sufficient permissions to write to the SteamCMD directory.

Downloading and Installing Valheim Server Files

Setting up a dedicated Valheim server involves downloading and installing the server files. This ensures you have a stable environment to host your game. Follow the steps below to get started:

Step 1: Install SteamCMD

SteamCMD is a command-line tool used to install and update the Valheim server files. Follow these steps to install SteamCMD:

Download the SteamCMD installer from the official Steam website.
Extract the contents to a preferred directory on your server.
Navigate to the SteamCMD directory and run the executable file to complete the installation.

Step 2: Download Valheim Server Files

Once SteamCMD is installed, you can proceed to download the Valheim server files:

Open a command prompt or terminal window.
Navigate to the SteamCMD directory.
Run the following commands to log in anonymously and download the server files:


    ./steamcmd.sh
    login anonymous
    force_install_dir /path/to/valheim/server
    app_update 896660 validate
    quit

Replace /path/to/valheim/server with your desired installation path.

Step 3: Configure the Server

After downloading the server files, configure the server to your preferences:

For projects that need guaranteed resources and full root control, a VPS is the right step up from shared hosting. With VPS hosting you get dedicated CPU/RAM, NVMe storage, a dedicated IP and high uptime, deployed in minutes.

Navigate to the installation directory.
Edit the start_headless_server.bat file (Windows) or create a shell script (Linux) with your server settings.
Specify the server name, world name, and password in the script.

Once configured, your Valheim server will be ready to run. In the next section, you’ll learn how to start your server and connect players.

Configuring Your Valheim Dedicated Server

Once you have your Valheim server set up on your Rackset hosting solution, it’s essential to configure it properly to ensure optimal performance and a smooth gaming experience. Follow these steps to configure your Valheim dedicated server.

Step 1: Access Server Files

Begin by accessing the server files on your hosting platform. You can do this via FTP or through the file manager provided by Rackset.

Locate the folder where Valheim is installed.
Find the server.cfg file, which contains key server settings.

Step 2: Edit Configuration Settings

Open the server.cfg file using a text editor. Here, you can adjust various settings to tailor the server to your preferences.

Server Name: Set a memorable server name for easy identification.
- Example: MyAwesomeValheimServer
World Name: Choose a unique world name.
- Example: ValhallaWorld
Password: Set a secure password to prevent unauthorized access.
Port: Ensure the server port is correctly set to 2456, which is the default for Valheim.

Step 3: Save and Restart the Server

After making the necessary changes to the configuration file, save your edits and restart the server to apply the new settings. This can usually be done through your Rackset control panel.

Step 4: Verify Server Status

Finally, check the server status to ensure it is running correctly. You can do this by attempting to connect to the server from the Valheim game client. If everything is configured correctly, you should be able to join and play without issues.

Opening Required UDP Ports for Valheim

To ensure a smooth and uninterrupted gaming experience on your Valheim dedicated server, it’s crucial to open the necessary UDP ports. This will allow the game traffic to flow freely between the server and the connected players. Below is a step-by-step guide on how to open the required ports.

Identify the Ports to Open

Default Port: Valheim uses UDP port 2456 by default.
Additional Ports: To ensure proper connectivity, open ports 2457 and 2458 as well.

Access Your Router’s Settings

Open a web browser and enter your router’s IP address in the address bar. Common IP addresses include 192.168.1.1 or 192.168.0.1.
Log in using your router’s administrator credentials. If you haven’t changed these, they might be the default credentials provided by the manufacturer.

Navigate to Port Forwarding Section

Look for a section labeled “Port Forwarding,” “Virtual Server,” or “NAT Forwarding.”
Click on it to open the port forwarding configuration page.

Configure Port Forwarding

Click on “Add New” or “Create New Rule” to start a new port forwarding rule.
Enter the following details:
- Service Name: Valheim
- Protocol: UDP
- External Port: 2456-2458
- Internal IP: Enter your server’s local IP address.
- Internal Port: 2456-2458
Save the changes and restart your router if necessary.

By following these steps, your Valheim server hosting should now have the necessary ports open to facilitate seamless player connections. Remember to check if any firewall software on your server also needs to have these ports opened.

Running Your Valheim Server as a Service

Running your Valheim server as a service ensures that it remains active and operational even if you’re not logged in to your server. This setup is particularly advantageous if you’re using Rackset’s dedicated server hosting, as it provides the reliability and resources needed for uninterrupted gameplay.

For heavy workloads and maximum performance, a dedicated bare-metal server gives you an entire physical machine. Rackset’s dedicated server deliver full hardware, root access and configurable port speeds for the most demanding sites and apps.

Installing NSSM

To run your Valheim server as a service on Windows, you’ll need to install a utility called NSSM (Non-Sucking Service Manager). This tool allows you to manage your server as a Windows service.

Download NSSM from the official website and extract it to a directory of your choice.
Open the Command Prompt as an administrator and navigate to the NSSM directory.
Run the following command to install NSSM:


nssm install ValheimServer

Follow the prompts to set up the service, specifying the path to your Valheim server executable and any necessary startup parameters.

Configuring the Service

Once NSSM is installed, you can configure the service to ensure optimal performance and reliability.

Automatic Start: Set the service to start automatically with Windows to ensure your server is always running.
Log Management: Configure logging options to keep track of server activity and troubleshoot issues.
Restart Options: Enable automatic restarts in case of a crash to maintain uptime.
