The MineOS user interface can be installed on CentOS systems using the yum package manager and either init.d or supervisord.
As written, these steps will install the webui with the following properties:
/usr/games/minecraft/var/games/minecrafthttps://[ip-address]:8443 in your browserroot, and support an unlimited amount of users with one daemonized (background) process.The following steps must be executed as root.
# yum -y install curl
# curl -sL https://deb.nodesource.com/setup_14.x | bash -
# yum -y install nodejs
The following steps install openjdk16 into a neutral space (/opt) and then symlinks it to /usr/bin/java. Note, that so long as root has a java binary in its $PATH, any version you choose–and even different installation methods–are permissible. This particular openjdk binary is chosen because CentOS 8 does not yet have Java 16 available in its normal repos at time of writing.

CentOS 8 offers systemd by default, which you can use to have the webui start at boot. You may, alternatively, use supervisord–but be sure to only choose one.
# cp /usr/games/minecraft/init/systemd_conf /etc/systemd/system/mineos.service
# systemctl enable mineos
Then, to manage the service:
# systemctl status mineos
# systemctl start mineos
# systemctl stop mineos
# yum install -y supervisord
# cp /usr/games/minecraft/init/supervisor_conf /etc/supervisor/conf.d/mineos.conf
# supervisorctl reload
Then, to manage the service:
# supervisorctl status mineos
# supervisorctl start mineos
# supervisorctl stop mineos
Once the background daemon is running, you can visit https://[ipaddress]:8443 in your web browser and you will see a user and password prompt. When creating minecraft and managing Minecraft servers, use an unprivileged user to log into the webui. Creating an unprivileged user (a user that is not root) can be accomplished with the adduser username command. The password you set during user creation will also be the password used for the web-ui.
CentOS8 installs firewalld by default. Using a firewall is highly recommended, but note that system rules will prohibit connectivity to the webui without adding in targetted rules.
Firewalld is outside the scope of this specific page. It is recommended to properly implement firewall rules, but to address firewalls at a different time after confirming webui operability; you can stop the firewall until next reboot with:
systemctl stop firewalld
If you prefer iptables to firewalld, you can change the firewall selected with:
systemctl disable firewalld
yum remove firewalld
