[Spacewalk-list] Problem installing Spacewalk on CentOS7 (Brand new install)

[Bruce Wainer]

Hello all,

I have found an issue installing SpaceWalk on CentOS7 that I have not been
able to diagnose/resolve (aside from the required downgrade of c3p0 as
mentioned here https://bugzilla.redhat.com/show_bug.cgi?id=1442140 ).

Issue: osa-dispatcher.service crashes on start with "'Not able to reconnect"

Background Information: Brand new install of CentOS7, set the hostname
durin the installer, ran updates, made sure hostname was correct in all
locations including /etc/hosts, followed the spacewalk installation
instructions verbatim.

Every time osa-dispatcher is started, "journal -xe" logs the following 3
times (I think due to three connection attempts)

Based on this it seems like jabberd isn't recognizing the hostname, but I
have followed the "Resolution" and "Diagnostic Steps" here:
https://access.redhat.com/solutions/327903 to no avail, as well as every
other google result related to "SASL callback for non-existing host". Since
my hostname was set during the installation, it was automatically and
correctly put into every config file that matters, other than /etc/hosts
which I have rechecked a haf dozen times. You can see in the journalctl
output that the host that jabberd is seeing matches the actual hostname.
I've done the complete setup from scratch twice to make sure I hadn't
missed any step in the installation instructions.

Joe Belliveau, it sounded like you ran into an issue like this with your
new install?

Thanks in advance for any assistance,
Bruce Wainer
