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

Tue Jun 27 21:10:06 UTC 2017

Robert,

Here is everything that is logged in /var/log/messages from the time I call
"systemctl start osa-dispatcher" to the time that the process dies:

-04:00: ('Error caught:',)
Jun 27 16:59:05 NETMAN osa-dispatcher: ERROR: unhandled exception occurred:
(unicode argument expected, got 'str').
Jun 27 16:59:05 NETMAN systemd: osa-dispatcher.service: control process
exited, code=exited status=255
Jun 27 16:59:05 NETMAN systemd: Failed to start OSA Dispatcher daemon.
Jun 27 16:59:05 NETMAN systemd: Unit osa-dispatcher.service entered failed
state.
Jun 27 16:59:05 NETMAN systemd: osa-dispatcher.service failed.

The three errors logged by osa-dispatcher seem to be caused by the
jabberd/c2s error. Also, the URL listed in the error is a page that
requires a RedHat support account which I do not have.

As a followup to the prior messages, here is a snippet from
/etc/jabberd/c2s.xml:
<c2s>
...
<local>
...
 <id require-starttls="false"
pemfile="/etc/pki/spacewalk/jabberd/server.pem" realm=""
register-enable="true">NETMAN.ad.brucewainer.com</id>
...
</local>
...
</c2s>

and from /etc/jabberd/sm.xml:
<sm>
<id>NETMAN.ad.brucewainer.com</id>
...
<local>
...
<id>NETMAN.ad.brucewainer.com</id>
...
</local>
...
</sm>

Again, both of these files seem to have been pre-configured properly by the
install script, and if there was a problem with these files it would mean
there is a bug in the installer, as I haven't edited these files, and there
was no instruction to do so.
