Step 2: Install Java

Once you are connected to the dedicated server, move on to installing Java.

We are going to set up the Java Development Kit (Open JDK), an open-source implementation of the Java platform.

The installation steps differ slightly depending on the Linux distribution running on your server.

Install Java on Ubuntu

1. Update the repository to ensure you download the latest version of OpenJDK:

2. Then, run the command to install the latest Java Development Kit:

3. Confirm the installation by typing y (yes) and press Enter.

4. Verify Java is installed on your Ubuntu server by running:

The output should respond with the version of OpenJDK installed on the system.

For a detailed installation guide for Ubuntu, refer to How to Install Java on Ubuntu.

Install Java on CentOS

1. Start by updating the package repository:

2. Then, install the Java Development Kit with:

3. The output should display it has successfully installed Java on the system. To confirm, you can check the Java version:

Step 3: Install Screen

Screen is a console application that keeps your server running when you're not connected.

- Install Screen on Ubuntu with: - To install Screen on CentOS, run: Step 4: Create a Directory for Minecraft Files

1. Create a minecraft directory where you will store the Minecraft files:

2. Then, move into the new directory with:

Step 5: Download the Required Configuration Files

1. Navigate to the Minecraft download page, right-click on the minecraft-server release and copy the link location.

2. Next, download Minecraft server files with the wget command. Paste the link location copied in the previous step:

The output informs you it has downloaded the Minecraft server files and saved them under the name server.jar.

3. Rename the server.jar file so it matches the name of the Minecraft edition downloaded. At the time of writing, the latest Minecraft server release is 1.16.4. Therefore, we used the following command to rename the server.jar file into minecraft_server.1.16.4.jar:

4. Next, execute the following command:

The output responds with an error informing you that you need to agree with the EULA (End User License Agreement) to run the service. Move on to the next step to do so.

Step 6: Accept Minecraft's EULA

1. List the contents of the /minecraft directory to verify you have the eula.txt file:

2. Open the EULA file with a text editor of your choice:

3. The file contains a URL that takes you to the Minecraft end user license agreement. Navigate to the web page and read through the license agreement.

4. If you agree with the terms, return to the terminal window and modify the eula.txt file. Change the line eula=false into eula=true.

5. Save the changes (CTRL+O) and exit the text editor (CTRL+X).

Step 7: Run Screen

Start a Screen session using the screen command and add the -S option to name the session:

Step 8: Run Your Minecraft Server

1. Try starting the Minecraft server again by rerunning the java command to executing the jar file:

Wait for the system to finish executing. You should get a message that the process is Done!, meaning that the Minecraft server is up and running.

2. You can now detach from the Minecraft screen by pressing Ctrl+a+d.

3. To reattach to the screen, press Ctrl+r.

Note: To make changes to the default configuration, refer to the server.properties file stored in the /minecraft directory.

Step 9: Configure Firewall

To allow incoming connections from Minecraft, you need to edit the firewall configuration. By default, Minecraft uses port 25565.

The following command enables port forwarding for ufw:

CentOS 6.X and older comes with iptables by default. The commands to enable port forwarding for iptables are:

CentOS 7.X and newer comes with firewalld by default. The following commands enables port forwarding for firewalld:

Step 10: Point a Domain at Your Minecraft Server

You can point a domain at your Minecraft server by updating the domain's DNS records. Add an "A" record for your domain with the following values:

Host : @ Value: IP address of your Minecraft server TTL: Automatic or 30 min Bear in mind, it can take up to 24 hours to carry out the DNS changes.

After reading this article, you should have successfully set up a dedicated Linux Minecraft server. Now you can enjoy all the benefits of having complete control over hardware resources while gaming.
