How to Install a Minecraft Server on CentOS/Ubuntu



  • Putty SSH Client
  • 1GB RAM VPS Server With CentOS 7 x64 Installed.


Login to your new CentOS 7 1GB RAM VPS Server and install Java 1.6.0 Open JDK.

ssh root@ip.ip.ip.ip
[root@vultr ~]# yum install java-1.6.0-openjdk
<some output here>
Is this ok [y/N]: y

Open the Minecraft server port in firewalld.

firewall-cmd --zone=public --permanent --add-port=25565/tcp
firewall-cmd --reload

Make a user to run your Minecraft server under. This is for security purposes as it is not good practice to run a Minecraft server as root.

adduser mcserver
#set a secure password.
passwd mcserver
#this allows you to run screen while su'd from root for the next step
chown mcserver `tty`

Now lets change users and install Minecraft! Change the wget URL accordingly for newer versions of Minecraft.

su - mcserver
mkdir minecraft
cd minecraft
wget -O minecraft_server.jar
chmod +x minecraft_server.jar
echo "eula=true" > eula.txt
#start your Minecraft Server
java -Xmx768M -Xms768M -jar minecraft_server.jar nogui


In order to run a Minecraft server, we need Java 1.7 to be installed on the server. To install Java 1.7, run the following commands:

sudo apt-get update
sudo apt-get install openjdk-7-jdk

Now,download the Minecraft server via wget. If you don't have wget installed, install it via sudo apt-get install wget.

chmod +x minecraft_server.jar

The Minecraft install is complete. Accept the license agreement.

echo "eula=true" > eula.txt

You can now start your Minecraft server via the following command:

java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui

This command starts the Minecraft server with 1024MB RAM allocated.

If you want the server to run in the background, you can install screen:

apt-get install screen
