sudo apt set up display

Now that you have the packages put in we have to allow the firewall to permit visitors to come in to our Minecraft server. Within the preliminary server setup that you just carried out you solely allowed ssh visitors. Now you want to allow for site visitors to come in through port 25565, which is the default port that Minecraft makes use of to allow connections. In some instances ufw will use named traffic rules, comparable to for ssh, which all the time uses port 22 by default, however in much less widespread cases like this one, we’ll specify the port quantity manually. Add the necessary firewall rule by operating the next command:

sudo ufw permit 25565

Now that you have Java put in and your firewall properly configured, you'll obtain the Minecraft server app from the Minecraft web site.

Step 2 - Downloading the newest Model of Minecraft

Now it is advisable to obtain the present version of the Minecraft server. You can do that by navigating to Minecraft’s Webpage and copying the link that says Download minecraft_server.X.X.X.jar, the place the X’s are the latest version of the server.
