- A duplicate of Minecraft Java Edition installed on an area Mac, Home windows, or Linux machine.
Step 1 - Installing the required Software Packages and Configure the Firewall
Along with your server initialized, your first step is to install Java; you’ll want it to run Minecraft.
Replace the package index for the APT package deal manager:
sudo apt replace
Next, set up the OpenJDK model 16 of Java, specifically the headless JRE. It is a minimal model of Java that removes the help for GUI applications. This makes it preferrred for working Java functions on a server:
sudo apt install openjdk-16-jre-headless
You also want to use a software program known as screen to create detachable server periods. display lets you create a terminal session and detach from it, leaving the method started on it working. That is necessary as a result of in case you have been to begin your server after which shut your terminal, this may kill the session and cease your server. Install screen now:
sudo apt set up display
Now that you have the packages installed we need to allow the firewall to allow traffic to come in to our Minecraft server. Within the preliminary server setup that you carried out you only allowed traffic from SSH. Now you need to allow for site visitors to are available in through port 25565, which is the default port that Minecraft uses to permit connections. Add the required firewall rule by running the next command:
sudo ufw allow 25565
Now that you've Java put in and your firewall properly configured, you will obtain the Minecraft server from the Minecraft webpage.
Step 2 - Downloading the latest Version of Minecraft
Now you have to download the current version of the Minecraft server. You'll be able to do this by navigating to Minecraft’s Webpage and copying the link that claims Download minecraft_server.X.X.X.jar, the place the X’s are the newest version of the server.
Now you can use wget and the copied hyperlink to obtain the server:
wget https://launcher.mojang.com/v1/objects/bb2b6b1aefcd70dfd1892149ac3a215f6c636b07/server.jar
If you happen to intend to upgrade your Minecraft server, or if you want to run completely different versions of Minecraft, rename the downloaded server.jar to minecraft_server_1.15.2.jar, matching the highlighted version numbers to whatever model you just downloaded:
mv server.jar minecraft_server_1.15.2.jar

display screen
After you have learn the banner that has appeared, press the Space bar. display screen will current you with a terminal session like regular. This session is now detachable, which means that you’ll be in a position to begin a command right here and depart it running.
You can now carry out your preliminary configuration. Do not be alarmed when this next command throws an error. Minecraft has designed its installation this manner in order that users should first consent to the company’s licensing settlement. You'll do that next:
1. java -Xms1024M -Xmx1024M -jar minecraft_server_1.15.2.jar nogui
Earlier than analyzing this command’s output, let’s take a better look at all these command-line arguments, which are tuning your server:
- Xms1024M - This configures the server to begin running with 1024MB or 1GB of RAM running. You can raise this restrict if you need your server to start out with extra RAM. Both M for megabytes and G for gigabytes are supported choices. For instance: Xms2G will begin the server with 2 gigabytes of RAM.
- Xmx1024M - This configures the server to use, at most, 1024M of RAM. You possibly can raise this limit if you would like your server to run at a bigger dimension, enable for more players, or if you feel that your server is working slowly.
- jar - This flag specifies which server jar file to run.
- nogui - This tells the server to not launch a GUI since this can be a server, and you don’t have a graphical user interface.

These errors were generated as a result of the server could not discover two obligatory files required for execution: the EULA (Finish Consumer License Agreement), found in eula.txt, and the configuration file server.properties. Fortunately, since the server was unable to seek out these information, it created them in your current working listing.

Upon getting set the choices that you want, save and shut the file.
Now that you have changed EULA to true and configured your settings, you'll be able to efficiently start your server.
Like last time, let’s begin your server with 1024M of RAM. Only now, let’s additionally grant Minecraft the flexibility to use up to 4G of RAM if it needs it. Remember, you are welcome to regulate this number to fit your server limitations or user wants:
1. java -Xms1024M -Xmx4G -jar minecraft_server_1.15.2.jar nogui
Give the initialization a few moments. Soon your new Minecraft server will begin producing an output much like this:
As soon as the server is up and running, you will notice the following output:
Your server is now running, and you've got been dropped into the server administrator control panel. Now sort help:
