- mongodb which is part of katello needs at least 4 gigs of free space in /var to install, otherwise the service won't start
- foreman and katello on the same server:
- the foreman proxy components and the candlepin components both try to listen on port 8443, so you need to change one of them. I changed the foreman proxy to 8444
- when I installed foreman and katello on the same server I could not create any "organizations". I kept getting an obscure error and couldn't find a way around it. nothing useful online........the error when trying to create the organization at the command line was: "Could not create the organization: resource have no errors". the behavior when trying to do it via the web UI was just that it would not go past the creation page.
