How to create a (Vanilla) minecraft server

Step 1: Download the server.jar file

Download the sevrer.jar file from the following website:

MCversions.net

Then place the file into an empty directory:

$ mkdir minecraft-server/
$ cd minecraft-server/
$ mv ~/Downloads/server.jar .

Step 2: Accept eula

Then you have to run the file:

$ java -Xmx1024M -Xms1024M -jar server.jar nogui

Then, replace "false" by "true" in eula.txt

$ sed -i "s/false/true/g" eula.txt

Step 3: Change the properties

Re-run the server.jar file. Then type /stop.

$ java -Xmx1024M -Xms1024M -jar server.jar nogui

Now you can edit the server.properties file. For instance, you can change "online-mode" to false if you want to allow cracked players to join the server.

$ nano server.properties

Step 4: Run the server and change some last stuff

Now, we can finally run the server:

$ java -Xmx1024M -Xms1024M -jar server.jar nogui

Now, into that console and change some gamerules. Those are my personal favorites:

/whitelist on
/whitelist add <player names>
/op <your player name>
/gamerule mobGriefing false
/gamerule doWeatherCycle false

Step 5: Making the server run in the background

We will now create a systemd service:

# nano /etc/systemd/system/minecraft.service

Paste the following code:

[Unit]
Description=Minecraft Vanilla Server
After=network.target

[Service]
Restart=always
RestartSec=1
WorkingDirectory=<path to minecraft-server>
ExecStart=java -Xmx1024M -Xms1024M -jar server.jar nogui

[Install]
WantedBy=multi-user.target

Finally, you can run the service:

# systemctl start minecraft
# systemctl enable minecraft

Conclusion

You now have a working Vanilla Miencraft Server. If you want to stop the server join the game and run /stop. Or run:

# systemctl stop minecraft

Also, if you want to make your server accessible world wide, you can open the port 25565. Your IP will be:

If you're running the game locally: localhost
If you're in the same network: <your hostname, find it by running hostname>
If you're not in the same network: <the public ipv4 address of the host>
