"Setting Up Game Servers on VPS"

Hosting your own game server gives you complete control over the gaming experience — custom maps, mods, player limits, and server rules are all yours to configure. A Data Mammoth VPS provides the dedicated resources and low latency needed for smooth, lag-free multiplayer gaming.

This guide covers how to choose the right VPS for gaming, general setup principles, and tips for running popular game servers.

Why Use a VPS for Game Servers?

Dedicated Resources

Unlike shared hosting, a VPS guarantees your game server gets the CPU, RAM, and bandwidth it needs. No other users can consume your resources, which means consistent performance during peak player hours.

Low Latency

By choosing a data center close to your players, you minimize ping times. Lower ping means smoother gameplay with less rubber-banding and input lag. See Data Center Locations & Regions to choose the best region.

24/7 Availability

Your game server runs around the clock on enterprise-grade infrastructure with redundant power and networking. Players can connect whenever they want without waiting for you to start the server.

Full Control

Install any game server software, mods, plugins, and custom configurations. Set your own rules, whitelist, and ban lists. Schedule automated restarts and backups.

Cost Effective

Hosting on a VPS is significantly more affordable than renting from game-specific hosting providers, and you get more flexibility and control.

Choosing the Right VPS Plan

Game server requirements vary significantly by game. Here are general recommendations:

• RAM is typically the most critical resource for game servers. Most games keep the entire game world in memory.
• CPU single-core performance matters more than core count for many game servers, as game loops are often single-threaded.
• Storage requirements are usually modest (5-20 GB) unless you have many world saves or extensive mod collections.
• Network bandwidth is rarely a bottleneck for game servers, but low latency is essential.

General Setup Process

While each game has specific installation steps, the general process is similar across most game servers:

Step 1 — Provision Your VPS

Order a VPS with the appropriate resources for your game. Choose a Linux distribution — Ubuntu 22.04 LTS is recommended for the broadest compatibility with game server tools and documentation.

Step 2 — Connect to Your Server

SSH into your VPS. See How to Connect to Your Server via SSH.

Step 3 — Create a Dedicated User

Do not run game servers as root. Create a dedicated user:

sudo adduser gameserver

Step 4 — Install SteamCMD (for Steam Games)

Many game servers are distributed through SteamCMD, Valve's command-line tool for downloading and updating game servers:

sudo apt update
sudo apt install steamcmd

Use SteamCMD to download game server files for Steam-based games.

Step 5 — Install the Game Server

Follow the specific game's server documentation to download and configure the server files. Common steps include:

Step 6 — Configure the Firewall

Game servers use specific ports for player connections. Configure your Data Mammoth cloud firewall to allow:

• The game's primary connection port (varies by game).
• Query ports for server browser listings (if applicable).
• SSH (port 22) for your management access.

Step 7 — Set Up Automatic Start

Create a systemd service so your game server starts automatically after VPS reboots:

Performance Optimization Tips

Allocate Memory Appropriately

For Java-based games (Minecraft), set explicit memory limits in the start script:

java -Xms4G -Xmx6G -jar server.jar

Leave at least 1-2 GB of RAM for the operating system and other processes.

Use SSD Storage

All Data Mammoth VPS plans include NVMe SSD storage, which is essential for game servers. SSD storage ensures fast world loading, chunk generation, and save operations.

Schedule Automatic Restarts

Game servers can develop memory leaks or performance degradation over long runtimes. Schedule automatic restarts during off-peak hours (e.g., daily at 4 AM) to keep performance fresh.

Monitor Resource Usage

Keep an eye on CPU, RAM, and network usage through your Data Mammoth dashboard. If your server consistently hits resource limits, consider upgrading your plan.

Enable Automated Backups

Set up regular backups of your game world and configuration files. Use Data Mammoth's snapshot feature for full server backups, and configure game-level backup scripts for world data.

Managing Your Game Server

Updates

Keep your game server software updated for security and compatibility:

• For Steam games, use SteamCMD to update server files.
• For non-Steam games, follow the developer's update instructions.
• Schedule updates during low-player periods to minimize disruption.

Mods and Plugins

Many game servers support mods and plugins. Install them according to the game's community guidelines. Tips:

• Back up your server before installing mods.
• Test mods on a separate server before adding them to production.
• Monitor performance after adding mods — some can significantly increase resource usage.

Player Management

• Use in-game admin tools or configuration files to manage whitelists, banlists, and player permissions.
• Consider setting up an admin panel or web interface if available for your game.

Troubleshooting

High Ping / Lag

• Ensure your VPS is in a data center close to your players. See Data Center Locations & Regions.
• Check CPU usage — high CPU may cause server-side lag.
• Reduce view distance or chunk loading settings.
• Remove resource-intensive mods.

Server Not Appearing in Browser

• Verify the correct ports are open in your cloud firewall.
• Check that the query port (if separate from the game port) is also open.
• Ensure the server is configured to be publicly visible (not set to LAN-only).

Crashes and Instability

• Check server logs for error messages.
• Ensure the server has enough RAM (increase allocation or upgrade your plan).
• Remove recently added mods to isolate the cause.
• Update to the latest server version.
