My son wanted to start playing Minetest, so i created a server on my laptop. But I was not able to run it all the time. But I did have a Raspberry PI 3B and i knew you could run Minetest on it. So I set out to get a server running, but it was a little harder then I thought.
Then I hopped onto the Minetest IRC channel, and NathanS was nice enough to help me. And he was able to compile a Stable 4.17.1 version and a 5.0 Dev version.
So requirements that you need (what I am running):
Raspberry PI 3B
Raspbian (command line if possible)
libhiredis-dev package (sudo apt-get install libhiredis-dev)
Able to share the game folder to install worlds and mods
Download corresponding build you want. Extract it. And run /EXTRACTEDFOLDER/bin/./minetestserver (i had to run sudo ./minetestserver)
Stable http://www.nathansalapat.com/downloads/0.4.17.1.tar.gz
Dev http://www.nathansalapat.com/downloads/5.0.tar.gz
Thank you to NathanS for the help and building the program.
