PaperSpigot server
------------------

RITcraft uses `PaperSpigot`_ to run the Minecraft server. This is a fork of the
`SpigotMC`_ project with a few added features and configurations that are good
for a classic, multiplayer server.

The server runs at ``mc.ritcraft.net`` and is run on port 30000. Since port
forwarding is enabled, players connect with the default ``:25565`` port and
they will reach the server.

A simple Bash script is run inside of a new `tmux`_ session to run the server:

.. code:: bash

   java -Xms2048M -Xmx2048M -jar rit-survival-spigot.jar

Copies of the configurations and world are backed up weekly into the Google
Cloud Platform.

Arguru also hosts various MySQL databases used for RITcraft and also other
servers running on the machine. A record of the databases is kept here.
