Introduction
Welcome to our guide on how to set up a Debian Minecraft server. Minecraft is one of the most popular video games that allows players to build, explore, and survive in a blocky 3D world. With a dedicated Minecraft server, you can create your own world and invite others to join you. In this article, we will take you through a step-by-step process to set up a Debian Minecraft server that is both reliable and secure.
Before we dive into the setup process, it is important to mention that Minecraft servers require a lot of resources and can be challenging to set up and secure. Therefore, this guide is intended for users with some technical knowledge and experience with Linux servers. However, even if you are a beginner, you can still follow the steps outlined in this guide.
Prerequisites
Before we get started, there are a few things you will need:
Item |
Description |
|---|---|
Debian server |
A VPS or dedicated server running Debian 10 or later. |
Root access |
You must have root access to the server. |
Java |
Java 8 or later must be installed on the server. |
RAM |
At least 2GB of RAM is recommended for small servers, and more for larger ones. |
Bandwidth |
You should have enough bandwidth to support the number of players on your server. |
How to Set Up a Debian Minecraft Server
Step 1: Update Your Server
Before installing any software, it is important to update your server to ensure that it has the latest security patches and updates. You can do this by running the following command:
sudo apt-get update && sudo apt-get upgrade -y
This command updates all the packages on your server and upgrades them to the latest versions.
Step 2: Install Java
Minecraft requires Java to run. Therefore, we need to install Java on our server. Run the following command to install Java:
sudo apt-get install -y default-jdk
This command installs OpenJDK, which is an open-source implementation of Java.
Step 3: Create a New User for Minecraft
It is not recommended to run Minecraft as the root user due to security reasons. Therefore, we will create a new user specifically for running the Minecraft server.
Run the following command to create a new user:
sudo adduser minecraft
Follow the prompts to set a password for the new user.
Step 4: Download and Install Minecraft Server
Now that we have Java installed and a new user created, we can download and install the Minecraft server.
Go to the Minecraft download page and download the server jar file. You can do this by running the following command:
wget https://launcher.mojang.com/v1/objects/...
Replace the URL with the latest version of the Minecraft server jar file.
Next, create a new directory for the server:
mkdir ~/minecraft-server
Move the downloaded server jar file to the new directory:
mv ~/Downloads/server.jar ~/minecraft-server/
Finally, navigate to the server directory and run the server:
cd ~/minecraft-serverjava -Xms1024M -Xmx2048M -jar server.jar nogui
This command starts the server with 1GB of RAM allocated by default and can be changed by modifying the -Xms and -Xmx flags. The nogui flag runs the server in the terminal window without a graphical interface.
Step 5: Configure the Server Settings
Now that the server is running, we need to configure some settings before players can connect.
First, open the server properties file:
nano ~/minecraft-server/server.properties
This file contains various settings that you can customize. Here are a few key settings:
Setting |
Description |
|---|---|
server-ip |
Set this to the IP address of your server if you are behind a router. |
server-port |
Change this to the port you want to use for your server. |
max-players |
Set this to the maximum number of players allowed on your server. |
motd |
Set this to the message that players will see when they join your server. |
Save the changes and exit the file.
Step 6: Allow Minecraft Through the Firewall
If you have a firewall enabled on your server, you need to allow Minecraft traffic through it. Run the following command to allow traffic on the default Minecraft port:
sudo ufw allow 25565/tcp
You can change the port number if you customized it in the server properties file.
Step 7: Test the Server
Now that we have everything set up, we can test the server by connecting to it from a Minecraft client.
Open Minecraft on your computer and click on the Multiplayer button. Click on the Add Server button and enter your server’s IP address and port number. Click Done and then click on the server to join it.
If everything is set up correctly, you should be able to join your server and start playing Minecraft!
