Thanks for the replies Eric. I tried those commands on both the current 
production server and a newly rebuilt test server using only the commands 
from the katello install page and got the following output:

[root@katello ~]# scl enable tfm 
'/opt/theforeman/tfm/root/usr/bin/passenger-status'
ERROR: Phusion Passenger doesn't seem to be running.
[root@katello-test ~]# scl enable tfm 
'/opt/theforeman/tfm/root/usr/bin/passenger-status'
ERROR: Phusion Passenger doesn't seem to be running.

[root@katello ~]# /usr/sbin/passenger-status 
ERROR: Phusion Passenger doesn't seem to be running.
[root@katello-test ~]# /usr/sbin/passenger-status 
ERROR: Phusion Passenger doesn't seem to be running.

If you look closely you'll see that one machine is katello and the other is 
katello-test and they both behave the same.
