Every guide, that I’ve seen on here, either officially or unofficially, does not seem to work, one way or another.
This is what worked for me and has gotten me a successfully running Minecraft server with the MineOS Web-UI for a couple of months and counting.
It may not be the most optimized, or the best way to do this (notably CentOS 8 being officially depreciated), but it’s what worked for me, and hopefully can help those with trouble installing MineOS and just want to get a Minecraft server up and running.

Prerequisites:
1.1. Download the Centos Stream 8 iso to a USB from here and install onto your target machine (Its easy as it has a GUI)
1.2. Pick the ‘Server with GUI’ option as the Base enviroment when they ask for your software selection, as it made it easy and has some cool features -
Get into root
sudo -i
- Install nvm (makes installing node easier)
curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | bash
source ~/.bashrc
nvm install 10
// node 10 is the only one that I found to work, going up or down broke things
- Add community repo (idk is it like the AUR?? Anyway some stuff didnt work until i did this)
dnf config-manager --set-enabled powertools
dnf install epel-release epel-next-release
- Install MineOS prerequisites
yum update -y
yum upgrade -y
yum -y install git wget openssl openssl-devel gcc-c++ make rsync screen rdiff-backup nodejs
- Install the webui
git config core.filemode false
chmod +x generate-sslcert.sh mineos_console.js webui.js
cp mineos.conf /etc/mineos.conf
cd /usr/games/minecraft
npm install --unsafe-perm
//If failed, do `nvm use 10` and `npm rebuild --unsafe-perm`. Also consider doing `npm-install node-gyp` if it still doesnt work
- Generate SSL cert
./generate-sslcert.sh
- Make stuff executable
chmod +x ./webui.js
- Run the thing
systemctl enable mineos
systemctl start mineos
- Check that the service is running
systemctl status mineos
- Testing:
Try to do ./webui.js. If it works, run
chmod +x ./reset_webui.sh
./reset_webui.sh
- Firewall stuff (I like ufw)
yum -y ufw
systemctl enable ufw
systemctl start ufw
ufw allow ssh
ufw allow 25565
ufw allow 8443
- Install Java 17 (for minecraft 1.20)
For other java versions, do basically the same thing but with the correct java version
wget https://download.oracle.com/java/17/latest/jdk-17_linux-x64_bin.rpm
yum -y install ./jdk-17_linux-x64_bin.rpm
- Reboot before you try it out
reboot now
