Creating a new Minecraft Server
This is a short and simple guide on how to set up a multiplayer server running the latest version of Minecraft.
This guide has been tested on Ubuntu 16.04 and 18.04.
Create a new Ubuntu droplet on DigitalOcean. Make sure it has at least 2GB of RAM, and you provide it with your SSH key.
SSH into the server and install Java, which is required for Minecraft to run.
apt-get update && apt-get install default-jdk java -version
Additionally, install Screen, which will allow us to run the server in the background.
apt-get install screen
Running the Server
Copy the download link of the latest Minecraft version here.
Create a directory to install the server files and download the server.
mkdir minecraft wget -O minecraft_server.jar <paste-download-link-here>
Start a new screen session.
screen -S Server
Run the server.
java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui
Exit the screen session.
CTRL + A, D
You might need to update your firewall configuration so that the correct ports are open if you are getting the message "Unable to connect to world".
ufw allow 25565/tcp
server.properties file is automatically created when you run the server for the first time. A list of properties can be found here.
Please note that after you edit the properties, you'll need to restart your server.
