Title:
  nova-placement-api port mismatch

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Description:
  Upgraded first from Mitaka to Newton, then to Ocata, and also upgraded openSUSE Leap 42.1 to Leap 42.3, so it's not a fresh installation, but since I couldn't find any hint to check the /etc/apache2/vhosts.d/nova-placement-api.conf.sample I assume this will also be a problem in a fresh installation.

  I followed OBS install guide [1] to configure nova-placement-api:

  1. Created the Placement API entry in the service catalog successfully...
  2. Created the Placement API service endpoints successfully:
    openstack endpoint create --region RegionOne placement public http://controller:8778
    openstack endpoint create --region RegionOne placement internal http://controller:8778
    openstack endpoint create --region RegionOne placement admin http://controller:8778
  3. Synced databases and registered cell0 database successfully...
  4. Enabled the placement API Apache vhost:
    mv /etc/apache2/vhosts.d/nova-placement-api.conf.sample /etc/apache2/vhosts.d/nova-placement-api.conf
    systemctl reload apache2.service

  Expected results:

  - nova-compute reports success ("Created resource provider record via placement API for resource provider...")
  - "nova-status upgrade check" shows upgrade status

  Actual results:

  - nova-compute reports:
  2017-10-16 10:53:31.247 8400 WARNING nova.scheduler.client.report [req-20cf1da3-86c4-4b03-bb13-84a54fd38425 - - - - -] Placement API service is not responding.

  - "nova-status upgrade check" shows connection error:

  The problem is a port misconfiguration in the nova-placement-api vhost, it doesn't match the endpoint configuration:

  Changing the port to match the port configured in the endpoints solves
  the problem.
