This article will demonstrate How to install Mine-craft Server on CentOS7 dedicated gaming server, cloud server, or virtual private server.

Before you begin this article make sure your server meets the following requirements:

At least 1GB of RAM is recommended

5 GB disk space

SSH root access

  1. Login to the root user of the server via SSH

ssh root@serverip

  1. Now, install Java Open JDK

yum install java-1.6.0-openjdk

When prompted, type Y to begin with the installation.

The screen will display “Complete!” when the installation is successful.

  1. Now, make a user to run your Mine-craft Server under.

For safety purposes, the Minecraft Server should run as its own user. We’ll create a user called mc.

adduser mc

Now, set the password on the mc user.

passwd mc

  1. Install wget, iptables-service, nano and screen.

If your server doesn’t have wget, it needs to get installed.

yum install wget iptables-service screen nano

  1. Log in as your Minecraft user and download Minecraft.

Switch users to the mc user.

su – mc

cd ~

Create a directory for Minecraft.

mkdir minecraft

Change into the minecraft directory.

cd minecraft

Navigate to the Minecraft Website and copy the URL of the latest .jar file


  1. Update the permissions on the Mine-craft Server file to be executable.

chmod +x minecraft_server.1.11.2.jar

Start screen:


  1. Start the Minecraft Server.

On a 1GB RAM server, run the following command.

java -Xmx768M -Xms768M -jar minecraft_server.1.11.2.jar nogui

If your server has less or more RAM, simply minus 256MB from the total number of MB of RAM your server has installed.

Edit the eula.txt file and change false to true.

  1. Exit your screen by typing Ctrl + A and then hitting D to detach.
  2. Update iptables.

Type exit to log out of the mc user and back into root.

If you are using iptables, open port 25565.

iptables -I INPUT -p tcp –dport 25565 –syn -j ACCEPT

Save the rule to iptables:

/sbin/service iptables save

  1. Now that your server is installed, you can connect to it from Minecraft. Launch Minecraft and select Multiplayer. Click Add Server. Now, enter server info and click Done. Click the play button next to your server to start playing!
