How to Create Your Own Free Private Minecraft Server

Hey there! Have you ever wanted to play Minecraft with your friends on your own private server? Well, I‘ve got great news – you can totally set up your own Minecraft server for free at home. It gives you complete control to play multiplayer Minecraft together without needing Realms or paying for an external server host.

In this step-by-step guide, I‘ll show you exactly how to make a private Minecraft server on Windows or Mac. I‘ve been running my own servers for years, so I‘m happy to pass on everything I‘ve learned to help you play with your crew. Follow along, and you‘ll be up and running in no time!

Why Should You Host Your Own Server?

Before we dig in, let me quickly explain some of the benefits of creating your own private server:

  • It‘s 100% free – No need to pay monthly fees for Realms or other hosting services.

  • You‘re in charge – Choose your own mods, plugins, rules, and control who plays.

  • Endless gameplay – A server allows 24/7 access for you and friends.

  • Learn new skills – From basic server admin to advanced plugins.

According to Back4App, over 112 million people play Minecraft each month. With so many active players, having your own server is a great way to enhance your enjoyment of the game with friends.

Alright, let‘s get started…here‘s exactly what you‘ll need to do:

Step 1 – Make Sure You Meet the Prerequisites

Before setting up your server, you should check that:

  • You and your friends have Minecraft: Java Edition – The server software only works with Java, not Windows 10 Bedrock Edition.

  • Your computer has at least 4GB of RAM – More memory means the server can support more players and mods. An SSD or fast CPU helps too.

  • You have decent internet speeds – For a smooth experience, aim for at least 15 Mbps upload speeds.

  • You can port forward your router – This opens your server to external connections. We‘ll cover how to do it later.

  • You know how to find your computer‘s local IP address – You‘ll need to share this with friends who want to join on your network.

If you meet the basics above, you‘re ready to move on to…

Step 2 – Download and Launch the Minecraft Server JAR File

The first step is to download the official server software from Mojang and launch it for the first time:

  1. Create a new empty folder somewhere like C:\MinecraftServer to store all your server files.

  2. Go to the downloads page and grab the Java server JAR file.

  3. Drag the server.jar file into the folder you just created.

  4. Open a command prompt/terminal and navigate to this new folder.

  5. Run the command java -Xmx1024M -Xms1024M -jar server.jar nogui

    This launches the server for the first time with some default settings, creating all the needed files.

  6. The server will briefly start then shut down. When it does, edit eula.txt and set eula=true to accept the EULA.

This initial launch sets up the basic folder structure and config. Now onto customization…

Step 3 – Tweak Your Server‘s Settings

Minecraft creates a file containing default configuration values. Open this file to personalize your server:

  • server-ip – Your computer‘s LAN IP so you can connect locally.

  • server-port – Default port is 25565, change if needed.

  • motd – Short message shown in the server list.

  • world – Folder name for your Minecraft world.

  • view-distance – 10 is default, higher is farther but needs more resources.

  • enable-command-block – Set to true to allow command blocks.

  • gamemode – Default mode for players: survival, creative, adventure, etc.

  • white-list – Only allow approved players, keep false for now.

There are tons more settings to play with, but this covers the basics of personalizing your server!

Step 4 – Allocate More Memory (RAM) to Your Server

The default RAM given to a Minecraft server is only 1GB. For better performance with more players/mods, you should increase this amount.

Here‘s how to allocate more RAM when launching the server:

  1. Close the server if it‘s currently running.

  2. Re-open your command prompt/terminal window.

  3. Type the launch command but change values after -Xmx and -Xms to increase memory.

  4. For example, to allocate 6GB on launch:

    java -Xmx6144M -Xms6144M -jar server.jar nogui

  5. Save the launch command somewhere to easily relaunch your server later.

Start with at least 4GB, and increase as needed. Just monitor RAM usage over time as you add more players andmods.

Step 5 – Port Forward Your Router

Alright, this next part is a bit technical but super important – you need to port forward your router to allow external connections to your server:

  1. Log into your router‘s admin page, usually located at or

  2. Find the port forwarding or virtual servers section.

  3. Create a new rule:

    • Service name: Minecraft Server
    • External/Internal port: 25565
    • Internal IP address: Your computer‘s LAN IP
    • Protocol: TCP & UDP
  4. Save your changes and you‘re all set!

This opens the 25565 port allowing your friends to connect from outside your home network.

Step 6 – Enable Friends to Join Your Server

You‘re so close to playing! To let your friends connect:

On your computer hosting the server:

  1. Launch the server if it‘s not already running.

  2. Join your own server on Minecraft by adding it in your Multiplayer menu. Use your public IP.

On your friend‘s computer:

  1. Open Minecraft Java Edition > Multiplayer > Add Server

  2. Enter your public IP and click Done.

  3. Select your server to connect!

A few tips once connected:

  • Use /op YOURNAME to promote yourself to admin.

  • Install plugins to add more functionality.

  • Make regular backups of your world in case of griefers.

Have fun playing with your friends! The server will stay online 24/7 as long as your computer is on.

Frequently Asked Questions About Private Servers

I know creating your own server raises a lot of questions for new admins. Here are some common ones:

Can I make my server public for anyone to join?

Absolutely! Just set white-list to false in your file. Keep in mind this opens your server to potential griefing.

How do I add more administrators?

The /op USERNAME command promotes players to admins. They‘ll gain access to all admin abilities.

How can I update my server when new Minecraft versions release?

It‘s easy! Just stop your server, download the latest server JAR from, replace the old one, and restart.

Can I tweak the difficulty or gamemode of my server?

Yep, just edit the difficulty and gamemode values in your file. Restart to apply changes.

My server lags when multiple people join. What should I do?

Allocate more RAM with the -Xmx and -Xms flags when starting your server. 4-8GB is good for 5+ players. An SSD also helps immensely.

Is it possible to install mods and plugins?

You sure can! Drop mods into the mods folder, and place plugin JARs in plugins. Restart the server to enable them. So many options to customize your experience!

What‘s the best way to backup my server‘s world?

Regularly create compressed zips or copies of your world folder for safekeeping. You can restore from backup if files ever get corrupted.

Recommended Mods & Plugins to Enhance Your Server

Once you have a basic server up and running smoothly, installing some mods and plugins can add extra functionality:

Fabric APIAllows installing Fabric mods like Lithium. Improves server performance.
LithiumGreatly improves general game mechanics and speeds to reduce lag.
PhosphorOptimizes lighting engine and chunk loading to reduce lag.
WorldEditPowerful world editing plugin for building large structures quicker.
WorldGuardAllows protecting certain areas of your world from griefing.

Follow the install guides for each mod/plugin to get them set up properly. The right addons can help your server run way more smoothly.

Migrating Your Singleplayer Worlds to Your Server

Already have some great builds or adventures on a local singleplayer world? Bring them online to share with friends on your server!

Here‘s how to migrate a singleplayer world:

  1. With the world loaded, go to Edit > Open World Folder

  2. Zip up that folder into one compressed file.

  3. Copy the zip over to your server computer.

  4. Delete the existing world folder on the server.

  5. Unzip your singleplayer world and place it as the new world folder.

  6. Restart your server, and your world is migrated!

Now anyone joining your server can explore and play in your existing singleplayer creations. Have fun bringing your world online!

Final Thoughts and Next Steps

Phew, we covered a ton of ground here! Let‘s recap the key steps:

  1. Download the server JAR and launch for the first time.
