With these advantages, Ubuntu is a great choice for hosting Minecraft servers. Let’s dive in and learn how to set up your own Minecraft server on Ubuntu!
Getting Started with Minecraft Server on Ubuntu
Before we get started with hosting a Minecraft server on Ubuntu, there are a few things that you need to do:
1. Install Java
Minecraft requires Java to run, so you need to make sure that you have Java installed on your Ubuntu server. To install Java, simply run the following command in your Ubuntu terminal:
sudo apt-get install default-jreThis will install the default Java Runtime Environment (JRE) on your server.
2. Check Your Server Requirements
Before you proceed with installing and setting up your Minecraft server, you need to make sure that your server meets the minimum system requirements. Here are the minimum system requirements for running a Minecraft server:
| System Requirements for Minecraft Server |
|---|
| 2 GHz CPU or equivalent |
| 2 GB of RAM |
| At least 10 GB of free disk space |
If your server doesn’t meet these requirements, you may experience performance issues or stability problems while running your Minecraft server.
3. Download Minecraft Server Files
To host a Minecraft server on Ubuntu, you need to download the Minecraft server files. You can download the latest version of the Minecraft server from the official Minecraft website:
https://www.minecraft.net/en-us/download/serverMake sure to download the version that is compatible with your Minecraft client. For example, if you are running Minecraft version 1.16.5, you need to download the Minecraft server version 1.16.5.
4. Create a New User for Minecraft Server
It is recommended to create a new user specifically for your Minecraft server. This will help you to separate your Minecraft server files from other files on your server and provide better security. You can create a new user by running the following command:
sudo adduser minecraftReplace “minecraft” with the username of your choice.
5. Set Up Firewall Rules
To ensure that your Minecraft server is accessible from outside your network, you need to set up firewall rules to allow incoming traffic on the Minecraft port (default port is 25565). Run the following command to allow incoming traffic on the Minecraft port:
sudo ufw allow 25565/tcpThis will allow incoming TCP traffic on port 25565.
With these steps completed, you are now ready to install and set up your Minecraft server on Ubuntu!
Installing Minecraft Server on Ubuntu
1. Install Screen
Screen is a terminal multiplexer that allows you to run multiple terminal sessions in a single window. This is useful for running your Minecraft server in the background, even if you disconnect from your server or shut down your SSH session. Run the following command to install Screen:
sudo apt-get install screen2. Navigate to Minecraft Server Directory
After downloading the Minecraft server files, navigate to the directory where you have downloaded the files. For example:
cd /home/minecraft3. Start Minecraft Server
To start the Minecraft server, simply run the following command:
java -Xmx1024M -Xms1024M -jar minecraft_server.jar noguiThe “-Xmx” and “-Xms” flags specify the maximum and minimum amount of RAM that the server can use (in this case, 1024 MB). The “nogui” flag disables the GUI interface, which is not needed when running the server on Ubuntu.
If your server has more RAM available, you can adjust the “-Xmx” and “-Xms” flags accordingly to optimize performance.
Configuring Minecraft Server on Ubuntu
After starting your Minecraft server, you can configure it to suit your needs. Here are some of the most common configuration options:
1. Server.properties
The server.properties file contains various settings that you can adjust to customize your Minecraft server. You can edit this file using any text editor, such as nano or vi. Here are some of the most commonly used settings:
| Server.properties Settings and Description |
|---|
| server-ip: The IP address that your server will bind to. If you want your server to be accessible from outside your network, set this to your public IP address. |
| server-port: The port number that your server will listen on. By default, this is set to 25565. |
| max-players: The maximum number of players that can join your server. |
| motd: The message of the day that players will see when they join your server. |
2. Whitelist
You can create a whitelist to restrict access to your Minecraft server only to players who are on the whitelist. To enable the whitelist, add the following line to your server.properties file:
white-list=trueThen, create a whitelist.txt file in the same directory as your server.properties file, and add the usernames of the players that you want to whitelist, one username per line.
3. Op List
You can create a list of operators (or “ops”) who have special privileges on your server, such as the ability to kick or ban players, or to run commands that are not available to regular players. To add a player to the op list, run the following command in the Minecraft server console:
op <username>Replace “<username>” with the username of the player that you want to add to the op list.
