You possibly can do that with the following command: sudo add-apt-repository ppa:openjdk-r/ppa Next, replace your package deal sources to reflect this addition: sudo apt update Lastly, set up the OpenJDK version 17 of Java, specifically the headless JRE. It is a minimal version of Java that removes the support for GUI purposes. This makes it very best for operating Java applications on a server: sudo apt install openjdk-17-jre-headless You additionally want to use a software program called display screen to create detachable server periods. screen permits you to create a terminal session and detach from it, leaving the process started on it working.

Set up screen now: sudo apt install display Now that you've the packages put in we have to enable the firewall to allow visitors to come in to our Minecraft server. Within the preliminary server setup that you just performed you solely allowed ssh traffic. Now you need to allow for site visitors to are available in by way of port 25565, which is the default port that Minecraft makes use of to permit connections. In some cases ufw will use named visitors rules, reminiscent of for ssh, which all the time makes use of port 22 by default, however in less widespread circumstances like this one, we’ll specify the port number manually.
