Bug 1247547

i just went through rebase hell to make this a downstream change too but after running as sanity check i get this trace [0] on controller. I need to revisit to find out why.

for tracking:

upstream @ https://review.openstack.org/#/c/206463/
downstream @ https://code.engineering.redhat.com/gerrit/#/c/56898

I spent a while poking at this today. I couldn't get a clean run when I tried to tell the apache module not to manage the service (and leave it up to the existing pacemaker service declaration for httpd later on in the overcloud_controller_pacemaker.pp to start it), i.e. what the current upstream review does. I consistently hit the error in comment 4 above. For that particular error, I traced it down to [1][2]. I think the expectation is that the horizon module will manage apache (via horizon::wsgi::apache). 

For now best I can offer is to make the service be disabled for system boot (which from the bug title, seems to be the actual request). I also moved the declaration of the pacemaker managed httpd service to much earlier. Updated upstream review @ https://review.openstack.org/#/c/206463/

That at least runs clean for me and ends up with httpd being disabled for boot startup:

[root@overcloud-controller-0 heat-admin]# systemctl status httpd
httpd.service - Cluster Controlled httpd
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; disabled)

The dashboard also seems fine but didn't poke too much, more testing appreciated:
