Learning How to Setup Minecraft server on 4GB RAM VPS gives you an affordable solution for hosting small to medium communities. A 4GB RAM allocation strikes an excellent balance between cost and performance, supporting 2-10 players comfortably while running vanilla or lightly modded servers.
In this detailed tutorial, I’ll walk you through the entire process of setting up a Minecraft server on a 4GB RAM VPS, based on hands-on experience with multiple server configurations. Whether you’re launching your first server or migrating from managed hosting, this guide covers everything you need to know about infrastructure, installation, optimization, and troubleshooting.
Setup Minecraft Server On 4gb Ram Vps – Understanding 4GB RAM VPS Requirements for Minecraft
Before diving into setup, you need to understand what 4GB RAM can realistically support when running how to setup Minecraft server on 4GB RAM VPS. RAM allocation directly impacts player count, world complexity, and overall stability. With 4GB total VPS RAM, you’ll dedicate 2-3GB to the Minecraft Java process, leaving the remaining 1-2GB for the operating system and background processes.
A 4GB RAM allocation supports vanilla Minecraft servers hosting 2-5 casual players smoothly. For 5-10 players with light mods or plugins, you can still maintain 20 TPS (ticks per second) with proper optimization. Beyond this, server performance degrades noticeably, causing lag spikes and player disconnections.
CPU cores matter equally when learning how to setup Minecraft server on 4GB RAM VPS. Minecraft is moderately CPU-intensive, especially with chunks loading and entity processing. Look for VPS providers offering at least 2-4 vCPU cores with consistent single-thread performance above 2.5GHz. Storage should be SSD-based rather than HDD for faster world loading times—a minimum of 30-50GB handles vanilla worlds comfortably.
RAM Allocation Breakdown
Your 4GB VPS RAM distribution should follow this pattern: allocate 2GB minimum and 3GB maximum to Minecraft, leaving 1GB for system operations. For lighter servers with fewer players, 1.5GB-2GB Minecraft allocation works fine. Monitor system memory usage after startup—if your VPS regularly hits 100% utilization, you’ve hit the ceiling and need additional resources.

Setup Minecraft Server On 4gb Ram Vps: Initial VPS Setup and Configuration
After provisioning your VPS, your first steps are crucial security and performance foundations for how to setup Minecraft server on 4GB RAM VPS. Most providers deliver a basic Linux installation requiring configuration before use.
Connecting to Your VPS
Access your VPS remotely using SSH (Secure Shell). On Windows, use PuTTY or Windows Terminal. On Mac/Linux, open Terminal and type: ssh root@your_vps_ip_address. Replace “your_vps_ip_address” with the IP address provided by your VPS provider. You’ll be prompted for your password or SSH key—enter your root credentials to connect.
System Updates and Security
Once connected, immediately update your system packages to patch security vulnerabilities. Run these commands in sequence:
sudo apt update && sudo apt upgrade -y
This updates package lists and installs all available security patches. The process takes a few minutes depending on your server’s update queue.
Creating a Dedicated Minecraft User
Running Minecraft as root poses security risks. Create a dedicated user account instead. Execute this command:
sudo adduser mcserver
The system prompts for a password—choose something strong but memorable. Grant this user sudo privileges for easier management. Add the mcserver user to the sudo group with this command:
sudo usermod -aG sudo mcserver
Switch to the new user account: sudo su - mcserver. You’re now operating as the mcserver user for all subsequent Minecraft operations.
Installing Minecraft Server Software
How to setup Minecraft server on 4GB RAM VPS requires choosing between server software types. Paper Server (recommended for most users) offers performance optimizations and plugin support over vanilla Mojang server. Let’s walk through Paper Server installation as it’s ideal for 4GB RAM systems.

Minecraft runs on Java, making it essential software for how to setup Minecraft server on 4GB RAM VPS. Install OpenJDK 17 (latest compatible Java version) using your package manager:
sudo apt install openjdk-17-jre-headless -y
The headless version omits graphical components, saving RAM. Verify installation by checking the Java version: java -version. You should see output confirming Java 17 installation.
Creating Server Directory Structure
Organize your server files in a dedicated directory. Create and navigate to it with these commands:
mkdir ~/mcraftserver
cd ~/mcraftserver
This creates a “mcraftserver” folder in your home directory. All server files will live here, making management straightforward when learning how to setup Minecraft server on 4GB RAM VPS.
Downloading Paper Server
Paper Server provides the latest optimized JAR file. Download the current stable version directly from their API:
wget -O server.jar https://api.papermc.io/v2/projects/paper/versions/1.21.1/builds/120/downloads/paper-1.21.1-120.jar
This command downloads the server JAR file (roughly 50MB) and names it “server.jar” for simplicity. The download takes 30-60 seconds depending on connection speed. Once complete, verify the file exists: ls -lh server.jar.
Configuring Server Settings and Properties
Before launching how to setup Minecraft server on 4GB RAM VPS, you must configure server properties and accept the End User License Agreement (EULA).
Accepting the EULA
First, launch the server once to generate the EULA file:
java -Xms2G -Xmx3G -jar server.jar nogui
The server starts, creates necessary files, then stops after a few seconds. You’ll see a message about needing to accept the EULA. Create the EULA acceptance file:
echo "eula=true" > eula.txt
This command creates an “eula.txt” file confirming your agreement with Minecraft’s terms of service.
Editing server.properties
The server.properties file controls fundamental settings when you setup Minecraft server on 4GB RAM VPS. Open it with nano text editor:
nano server.properties
Key settings to adjust for 4GB RAM systems:
- max-players=5 (set to your intended player count, max 10 for stability)
- difficulty=2 (0=peaceful, 1=easy, 2=normal, 3=hard)
- pvp=false (prevents player-versus-player damage if desired)
- view-distance=8 (lower values reduce RAM usage; default is 10)
- simulation-distance=8 (controls chunk processing distance)
- server-port=25565 (default Minecraft port; change if running multiple servers)
- enable-rcon=true (optional; enables remote server control)
Save changes by pressing Ctrl+X, then Y, then Enter. These settings optimize how to setup Minecraft server on 4GB RAM VPS for maximum stability with your player count and hardware constraints.
Starting and Running Your Server

Entity Limiting
Excessive mobs, animals, and item entities drain resources. Add these settings to server.properties:
spawn-animals=true
spawn-monsters=true
entity-broadcast-range-percentage=80
These limit entity spawning while maintaining gameplay variety. You can further cap entity counts using plugins like Paper’s built-in entity limits.
Network Optimization
Reduce network overhead with these server.properties additions:
network-compression-threshold=256
max-tick-time=60000
Compression threshold optimizes bandwidth usage while max-tick-time prevents watchdog timeouts during server spikes when how to setup Minecraft server on 4GB RAM VPS experiences temporary load increases.
Monitoring System Resources
Reattach to your screen session to monitor performance: screen -r MinecraftServer. Watch the server log for warnings about memory pressure. Open a second SSH connection and run top or htop to check real-time CPU and RAM usage. Your Java process should use 2-3GB RAM with occasional spikes to 3GB under load.
