How to Create a Private Game Server on a VPS

Most private game servers start with the same conversation: a group of friends gets tired of overcrowded public servers, random admins, or hosting plans stuffed with features nobody actually uses. At some point someone asks the obvious question — why not just run our own server? A VPS, short for virtual private server, is one of the most practical answers to that question. It gives you a dedicated slice of computing resources that behaves like a real machine, with full control over what runs on it, which mods get installed, and when it restarts.

This guide walks through what a VPS actually is, how to set one up for gaming, what kind of hardware different games need, and which mistakes tend to catch first-time admins off guard. Whether the goal is a cozy Valheim world for five people or a small CS2 server for a community, the underlying process is almost the same — only the details change.

What a VPS Is, and Why It Works Well for Game Servers

Before getting into setup, it helps to get the terminology straight, especially if server administration is new territory.

A VPS is a virtual machine running on a physical server, but it behaves like an independent computer with its own operating system, IP address, CPU allocation, and storage. Unlike shared hosting, where dozens of accounts compete for the same limited resources, a VPS gives a guaranteed (or at least predictable) share of CPU and RAM. Unlike a dedicated server, it costs a fraction of the price and can be resized in minutes rather than requiring a hardware swap.

Running a server at home is technically an option too, but it comes with its own headaches: dynamic IP addresses, router configuration, electricity costs, and the simple fact that the server goes offline whenever the home internet does. A VPS removes all of that — it sits in a data center with stable power, a fixed IP, and a network connection that's usually faster and more reliable than a home line.

One more distinction worth making early: the game server is not the same thing as the game itself. It's a separate piece of software — often free, sometimes downloaded through tools like SteamCMD — that simulates the game world and lets players connect to it. The VPS just provides the environment where that software runs.

How to Set Up a Private Game Server: Step by Step

Step 1: Choose a VPS Plan That Matches Your Game

Specs needed depend heavily on which game is being hosted and how many players will join. A vanilla Minecraft server for five friends barely needs more than 2 GB of RAM, while a heavily modded ARK: Survival Evolved server can comfortably eat through 8–12 GB. CPU clock speed matters more than core count for most game servers, since simulation logic for many titles runs largely on a single thread.

Storage type matters too — SSD or NVMe drives noticeably reduce world-loading times and chunk generation lag compared to older spinning disks. Location is the other factor people tend to forget: picking a VPS region close to where most players are based keeps ping low. Providers such as Serverspace offer a range of VPS configurations across different regions, which makes it easier to match both performance and latency requirements without overpaying for resources that won't be used.

Step 2: Pick an Operating System

For most popular game servers — Minecraft, Valheim, Rust, CS2, ARK on Linux builds — Ubuntu LTS or Debian is the standard choice. They're lightweight, well documented, and free, which leaves more RAM available for the actual game process. Windows Server is occasionally necessary for games or mods that ship Windows-only binaries, but it consumes more resources just running in the background, so it's worth checking whether a Linux build of the server software exists first.

Step 3: Connect to the Server

On Linux, the connection happens over SSH. From a terminal (or a tool like PuTTY on Windows), the basic connection looks like this:

ssh root@your_server_ip

After entering the password (or using an SSH key, which is the safer option), the terminal drops into the VPS's command line. Everything from here happens remotely — there's no need to physically touch the hardware.

Step 4: Update the System and Install Core Tools

A fresh VPS image is usually minimal, so the first thing worth doing is updating packages and installing a few essentials. On Ubuntu or Debian, that means:

sudo apt update && sudo apt upgrade -y
sudo apt install -y screen curl wget unzip

screen (or its alternative, tmux) deserves special mention — it lets a process keep running even after the SSH session closes, which is exactly what's needed for a game server that has to stay online overnight.

Step 5: Install and Configure the Game Server Software

This is the step that varies the most between games. Java-based titles like Minecraft need a Java runtime and a server JAR file. Source-engine games such as CS2 are usually installed through SteamCMD, Valve's command-line tool for downloading dedicated server files. A typical SteamCMD sequence looks something like this:

mkdir ~/steamcmd && cd ~/steamcmd
wget https://media.steampowered.com/client/steamcmd_linux.tar.gz
tar -xvzf steamcmd_linux.tar.gz
./steamcmd.sh +login anonymous +app_update [APP_ID] validate +quit

The app ID changes depending on the game (CS2, Rust, ARK, and so on all have their own). After the download finishes, each game has its own configuration file — server name, password, map rotation, difficulty, mod list — that's edited as a plain text file before the first launch.

Step 6: Open Ports and Configure the Firewall

Game servers communicate over specific ports, and most VPS images come with a firewall enabled by default that blocks everything except SSH. If the right ports aren't opened, players simply won't be able to connect — no error message, just an endless "connecting" screen. On Ubuntu, opening a port with ufw looks like this:

sudo ufw allow 25565/tcp
sudo ufw allow 25565/udp
sudo ufw enable

The port number and protocol depend on the game — Minecraft uses 25565/TCP by default, while many survival and shooter games rely on UDP for both the game traffic and a separate query port used by server browsers.

Step 7: Keep the Server Running Around the Clock

Closing the SSH session normally kills any process started inside it, which isn't ideal for something meant to run 24/7. A simple fix is starting the server inside a screen session:

screen -S gameserver
./start.sh
(detach with Ctrl+A then D)

A more robust setup uses a systemd service, which restarts the server automatically if it crashes and starts it on boot:

[Unit]
Description=Game Server
After=network.target

[Service]
WorkingDirectory=/home/gameserver
ExecStart=/home/gameserver/start.sh
Restart=on-failure
User=gameserver

[Install]
WantedBy=multi-user.target

Step 8: Set Up Backups and Updates

World saves and configuration files are worth backing up regularly, ideally with a scheduled cron job that compresses the world folder and copies it somewhere outside the VPS — another storage volume, an object storage bucket, or even a local machine. Game updates are another recurring task; some games push frequent patches, and an outdated server can suddenly stop accepting connections from updated clients without warning.

Advantages and Drawbacks of Running a Game Server on a VPS

On paper, a VPS sits in a comfortable middle ground between a home setup and a fully managed game hosting service. In practice, that middle ground comes with its own trade-offs.

• Full control — every setting, mod, plugin, and configuration file is accessible, with no restrictions imposed by a hosting panel.
• Cost efficiency — for small to medium player groups, a VPS often costs less per month than a managed game server with the same specs.
• Flexibility — the same VPS can switch between games, run multiple servers side by side, or host other tools entirely.
• Privacy — no third party manages the world data, player list, or chat logs.

• Self-managed maintenance — updates, backups, and security patches are the admin's responsibility, not the provider's.
• A learning curve — basic command-line comfort is needed, even if the steps themselves aren't complicated.
• Shared underlying hardware — depending on the plan, the physical host may be shared with other VPS instances, which can occasionally cause minor performance variance.
• No built-in game panel — unlike some managed hosts, there's no pre-installed control panel unless one is set up manually (tools like Pterodactyl can help here).

Limitations and Risks to Keep in Mind

A VPS handles small and medium communities well, but it has its limits. Games with large player counts — 50, 100, or more — need significantly more RAM and CPU than a budget VPS plan provides, and at some point scaling up a VPS costs roughly the same as renting a dedicated server with better raw performance.

Network exposure is another consideration. A publicly reachable game server is, by definition, reachable by anyone — including people running port scans or basic DDoS tools. Most reputable VPS providers include some level of network protection, but a server with weak admin passwords or an exposed RCON port is still an easy target.

Worth checking too: some game publishers have specific rules about private servers in their terms of service. Most sandbox and survival games are fine with it, but a handful of competitive titles restrict or ban unofficial dedicated servers outright. A quick check of the game's EULA before investing hours in setup can save a headache later.

Practical Scenarios for a Private Game Server

A Minecraft World for Friends and Family

This is the classic use case — and for good reason. A vanilla Minecraft server runs comfortably on a modest VPS, supports a handful of players without strain, and can later be extended with plugins (Spigot, Paper) for things like land claims, economy systems, or anti-griefing tools. World size grows over time, so storage planning matters more here than CPU power.

A Survival Server for Valheim, Rust, or ARK

Survival games tend to be more demanding, particularly as the world map expands and more structures get built. ARK in particular is known for heavy RAM usage, while Rust's procedurally generated maps can grow large fast. These games benefit from a VPS plan with extra headroom rather than the bare minimum — a server that runs fine at launch can slow down noticeably a few weeks into a wipe cycle.

A Small Competitive Server for CS2

Source 2 servers are relatively light on resources compared to survival games, but tick rate and player count both affect CPU load directly. A community running practice servers, scrims, or casual matches for 10–12 players can get by with a fairly modest VPS, as long as the location is close to where most players connect from — latency matters more here than almost anywhere else.

A Heavily Modded Multiplayer World

Modded Minecraft (Forge, Fabric) or modded ARK servers behave very differently from their vanilla counterparts. Mods add extra simulation load, memory overhead, and sometimes extra network traffic. A server that runs a vanilla game smoothly on 2 GB of RAM might need 6–8 GB once a sizable modpack gets layered on top.

A Community Hub Tied to Discord

Some communities run more than just a game server — bots that sync in-game events to Discord, web dashboards for managing whitelists, or small APIs that show server status. A VPS handles all of this on the same machine as the game server, as long as resources are split sensibly between the game process and the supporting tools.

Recommended VPS Specs by Game

These numbers are starting points rather than hard rules — a server that sits comfortably within these ranges leaves room for plugins, backups, and the inevitable growth of a world or base over time.

Common Mistakes and How to Avoid Them

Most issues with a freshly set up game server come down to a small set of recurring problems. Knowing them in advance saves a fair amount of troubleshooting later.

• Forgetting to open the right ports. A server that "doesn't show up" for friends is, in most cases, a firewall issue rather than a configuration error.
• Mixing up TCP and UDP. Many games need both protocols open on the same port, or different ports for game traffic versus the query/browser port.
• Underestimating RAM for modded servers. A modpack that runs fine on a local PC with 16 GB available can behave very differently with 4 GB on a VPS.
• Skipping backups before updates. A bad update or a broken mod can corrupt a world save — a recent backup turns that from a disaster into a five-minute fix.
• Leaving default passwords on admin tools. RCON, web panels, and database credentials should never stay on their defaults, especially on a server with a public IP.

Wrapping Up: Getting the Server Online

Setting up a private game server on a VPS isn't difficult so much as it's a sequence of small, well-defined steps — pick the right specs, choose an OS, connect, install the server software, open the right ports, and keep it running. None of these steps require deep technical expertise on their own, even if the combination looks intimidating at first glance.

The practical starting point is matching the VPS plan to the game: light titles like Terraria or vanilla Minecraft run fine on entry-level configurations, while modded worlds and survival games with larger player counts need more headroom. From there, providers offering a range of VPS server configurations make it straightforward to start small and scale up as a community grows, without committing to dedicated hardware from day one.
