Just be aware that the Pi is fast but not thousands of moving entities in Minecraft fast. We solved our issue by killing about 480+ Iron Golems with /kill that's up to you. You can gently overclock your Pi4 if it has a fan by adding this to the end of your /boot/config.txt (read articles on overclocking a Pi to be safe) over_voltage=3Īnd/or you can disable the Minecraft internal watchdog for ticks by setting max-tick-time to -1 in your server's server.properties file. With very large Minecraft worlds or worlds like my son's with 500+ Iron Golems and Chickens, you may get an error like : A single server tick took 60.00 seconds (should be max 0.05) Then you can connect to your world with that name or ip. You can then run ifconfig at and command line and get your Pi's IP address, or type hostname to get its name. Since I have a Raspberry Pi 4 with 4g gigs of RAM and it'll be doing just this one server, I felt 2500 megs of RAM was a sweet spot. You could also make a start.sh text file with pico then chmod +x to make it an easier single command way to start your server. java -Xmx2500M -Xms2500M -jar server.jar nogui Press the up key and run your command again. You'll get a warning that you didn't accept the EULA, so now open "pico eula.txt" and set eula=true, then hit Ctrl-X and Yes to save the new file. Java -Xmx2500M -Xms2500M -jar server.jar nogui So we'll make a folder, download the server.jar, then run it. Right-click and copy link into your clipboard We are going to PASTE it (right click with your mouse) after the "wget" below. It'll say something like "Download minecraft_server.1.16.2.jar and run it with the following command." That version number and URL will change in the future. There are other Minecraft 3rd party Java Servers you can use, the most popular being Spigot, but the easiest server you can run is the one from Minecraft themselves. Do your standard update stuff, and also install a JDK: sudo apt update You can use Putty, but I like using Windows 10's built-in SSH. Remember the default user name is pi and the password is raspberry. If you want to make things faster for setup and possibly set up your Pi without having to connect a monitor, mouse, or keyboard, mount your SSD card and create a new empty file named ssh, without any extension, inside the boot directory to enable ssh on boot. I like NOOBS as it's super easy to setup. I was running a Minecraft Server in a Docker container on my Synology NAS but I thought teaching him how to run Minecraft Server on a Raspberry Pi 4 we had lying around would be a good learning moment.įirst, set up your Raspberry Pi. He was just hosting on his laptop and then forwarding a port but that means his friends can't connect unless he's actively running. My 14 year old got tired of paying $7.99 for Minecraft Realm so he could host his friends in their world.
