Which type of LON-CAPA cluster does this server/VM belong to?
IMPORTANT: to take advantage of the cluster options 1) and 3),
you must have been or expect to be accepted into the cluster.
Contact loncapa\@loncapa.org for access.
1) PRODUCTION - you have (or will) connect this machine to the
LON-CAPA content sharing network. This setting is for
schools, colleges, and universities, that currently
are running - or in the future will run - courses.
2) STAND-ALONE - you want this machine to run in 'stand-alone' mode and
not be connected to other LON-CAPA machines.
3) DEVELOPMENT - you want to do software (not content!) development with
this workstation and eventually link it with
workstations of other LON-CAPA software developers.
4) RUNNING YOUR OWN CLUSTER - this machine is not in the standard LON-CAPA
cluster and won't be in the future.
(This choice is unlikely what you want to select.)

****** Information about Country, State or Province and City *****
A two-letter country code, e.g., US, CA, DE etc. as defined by ISO 3166,
is required. A state or province, and a city are also required.
This locality information is included in two SSL certificates used internally
by LON-CAPA, unless you are running standalone.
If your server will be part of either the production or development
clusters, then the certificate will need to be signed by the official
LON-CAPA Certificate Authority (CA). If you will be running your own
cluster then the cluster will need to create its own CA.
