I might only want to have a maximum of 5 people on the server, but it can also be that there are more. I would also like to use the Raspberry Pi as a server for other purposes.
Can someone recommend how much RAM I need at least?
I would worry more about the CPU than about the ram. 2GB should be enough btw
This should just be a simple server.
I looked around the internet a bit: a Raspberry is enough
You should already have 8GB.
I recommend the Raspberry Pi 4B with 8GB RAM. This is available e.g. Here as a starter set: https://www.reichelt.de/de/de/das-reichelt-raspberry-pi-4-b-8-gb-all-in-bundle-rpi-4b-8gb-allin-p284444.html?r=1 This consists of the following components:
Raspberry Pi 4B with 8GB RAM
casing
Heat sink
16GB memory card
power adapter
HDMI cable
As the operating system for a Minecraft server, I recommend Raspberry Pi OS Lite (the successor to Raspbian Lite). This is without a desktop: https://www.raspberrypi.org/software/operating-systems/
To flash the operating system to the memory card, I recommend the tool balenaEtcher https://www.balena.io/...io/etcher/ Available for Windows, Mac and Linux. This can also flash ZIP-packed images. The memory card is automatically formatted before each flash process.
The Minecraft server is configured via SSH access. All you have to do is install the SSH client PuTTY under Windows: https://the.earth.li/~sgtatham/putty/latest/w64/putty-64bit-0.74-installer.msi
PuTTY is also available for Mac https://macsoftware.ch/putty-fuer-mac/ Before installing PuTTY, you have to install XQuartz on the Mac: https://www.xquartz.org/
Linux users can install PuTTY via the package manager.
PuTTY has the advantage that you can save the SSH connection configurations. This saves typing every time.
2 GB is sufficient for 5-10 people.
With a lot of plugins, unlimited worlds, etc. You get a maximum of 4 GB.
Unfortunately, I'm not familiar with RasperryPi, but should also apply there.
Is 8 ram really that necessary?
So how much ram does my raspberry need?
As long as it's just that.
You can see that in my selection: I would take 4GB.
