How to Build a Minecraft Server on your CentOS 7

MINECRAFT is an open world video game developed in Java, originally created by Markus "Notch" Persson and maintained by Mojang AB. It is presently owned by Microsoft studios as well. This game involves players interacting within by placing and breaking various types of blocks in a three-dimensional environment. The players can even  collect resources, build structures, battle mobs, manage hunger, explore the land  simply, creates & destroys structures on both multiplayer servers and singleplayer worlds across multiple game modes. These are the six game modes available as below:

  • Survival
  • Creative
  • Hardcore
  • Adventure
  • Spectator
  • Demo

In this article, I'm discussing on how to setup a Minecraft server on a CentOS 7 build.


First of all, let me go through the installation requirements.


  •  VPS or Dedicated servers with SSH access
  •  RAM : 1GB or more
  •  Disk Space : 5GB or more
  •  Install the latest Java compatible with the OS architecture.
  •  Disable Selinux

Let us start with the installation procedures. We need to install the latest Java version for the server depending on its architecture.

Install JAVA

Minecraft server requires the latest JAVA version to be installed and running.

root@server1 ~]#yum install java-1.6.0-openjdk

These many packages will be installed. Now we need to download the Minecraft server package from there website into the "minecraft" folder.

Create a MINECRAFT folder

Create a minecraft folder for the installation and other game files. It is always advised to run this executable inside a dedicated folder, as it creates several configuration files. This will make it more easier to organize and locate all the files.

root@server1 ~]#mkdir minecraft
[root@server1 ~]# cd minecraft

Download the Minecraft server jar file

Download the minecraft .jar file to the minecraft folder and modify the .jar file permissions to make it executable.

[root@server1 minecraft]# wget

Make sure Screen is installed in your server or else run this command to install screen for your server.

[root@server1 minecraft]# yum install screen

Run the Application

Now get into a screen session and run the minecraft .jar file as per the required resolution and hardware settings. Both the Java and the executable version can be run from the command line with extra parameters to configure depending on the memory, graphical interface, mode, architecture etc.

Depending on my server capability, I prefer to ran my Minecraft server on 512MB without graphical interface to lower the CPU and memory resource usages.

root@server1 minecraft]# java -Xmx512M -Xms512M -jar minecraft_server.jar nogui

The launching text will look like this:
229 recipes
27 achievements

You can get back to your normal screen by press ctrl +A +D

You can get back to the screen where Minecraft is running by using the screen resume command.
# screen -r (screenid)
You can even run this executable using 1GB memory or more depending on your server specifications. This is how we run for 1GB memory usage.

java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui
Tip: If you want to spare more memory, you may set the -Xms parameter with a lower value, say:

java -Xms512M -Xmx1024M -jar minecraft_server.jar nogui

The parameter controls how much memory is reserved on startup. Your server will start with 512MB RAM and whenever it needs more memory it will allocate some until it reaches the allotted maximum value of 1GB.

Hurray!! Your Minecraft is all set and it should be running good. You can have your friends login to your server and start building.

You can have any number of players depending on your server resources. There is a software called Multicraft to manage your Minecraft servers. You can download this software from their official website and use it as a user friendly control Panel managing your MC servers.
I hope you enjoyed reading this article. I would recommend your valuable suggestions and comments on this.

Thank you and have a great day :)

  1. Hello,
    Thanks for posting this tutorial.
    I had trouble with the Ctrl +A +D command - it does work for me.
    And once the server is running, how do I know what URL to use to connect to the game?

    Thanks again,
