Download the Server Software

First, grab the official Minecraft server jar file from Minecraft.net’s download page. You’ll want the latest version that matches your desired gameplay experience. Create a dedicated folder on your computer for the server files – this keeps everything organized and makes management easier.

Set Up Java Runtime Environment

Your computer needs Java to run the server. Most modern systems have it installed, but you might need Java 17 or newer for recent Minecraft versions. Download it from Oracle or use OpenJDK if you prefer open-source options.

Initial Server Launch

Place the server jar file in your dedicated folder and run it once using the command line or by double-clicking. This first run will fail intentionally – it creates essential files including the End User License Agreement (EULA). Open the eula.txt file and change “eula=false” to “eula=true” to accept the terms.

Configure Server Settings

The server.properties file controls everything from world generation to player limits. Key settings include:

  • server-port: Usually 25565 (default)
  • max-players: How many people can join
  • gamemode: Survival, creative, adventure, or spectator
  • difficulty: Peaceful, easy, normal, or hard
  • online-mode: Enables Mojang account verification

Network Configuration

For friends to connect from outside your home network, you’ll need to configure port forwarding on your router. Forward port 25565 (or whatever you chose) to your computer’s local IP address. Some routers have gaming modes that simplify this process.

Launch and Connect

Start the server again after configuring everything. You’ll see console output indicating the server is running. Players can connect using your public IP address, while you can use “localhost” or “127.0.0.1” to join your own server. The console lets you run commands, monitor player activity, and manage the world even when you’re not playing.

Running your own server opens up endless possibilities for customizing your Minecraft experience with friends and exploring the creative potential of this beloved sandbox game.

TL;DR

Download the Minecraft server jar, install Java, accept the EULA, configure server.properties, set up port forwarding, then launch to create your multiplayer world.
