How was your system installed? Packstack? openstack-dashboard installed since ever /etc/httpd/conf.d/openstack-dashboard.conf. If that file is removed, it's clear that's being recreated on each package update (and upgrade). Removing such config files is a really bad idea. I just verified the behaviour on rhel6 rhos5: Packstack removes the default provided file from openstack-dashboard: rpm -ql openstack-dashboard | grep /etc /etc/httpd/conf.d/openstack-dashboard.conf and replaces that file by its own configuration files: -rw-r--r--. 1 root root 758 Jul 18 10:43 15-default.conf -rw-r--r--. 1 root root 1471 Jul 18 10:43 15-horizon_ssl_vhost.conf -rw-r--r--. 1 root root 1203 Jul 18 10:43 15-horizon_vhost.conf *This will break on EACH openstack-dashboard update*. openstack-dashboard will re-install that file, when it doesn't exist on package updates and upgrades. The file /etc/httpd/conf.d/openstack-dashboard.conf has been there since RHOS2.1, when updating from earlier versions, packstack is not run, so that file will not get removed. verified in the latest build. If I understand it correctly, the fix is for packstack. This ensures that during installation the configuration file is cleaned with a message, so that it's changed and not replaced with the new version upon upgrade. But this is for the future installation; current installations are going to break. Is it worth mentioning somewhere in the release notes?

So what happened at your installation: # you installed via packstack # openstack-dashboard got installed by packstack # packstack removes openstack-dashboards config file /etc/httpd/conf.d/openstack-dashboard.conf # packstack writes (about the same config) to /etc/httpd/conf.d/15-horizon_vhost.conf # if you install or upgrade openstack-dashboard, you'll get packages version in /etc/httpd/conf.d/openstack-dashboard.conf installed as well. # The regression was, that packstack changed config files location, there are several now (when installed via packstack) and they have their separate purpose.

Description of problem: When dashboard packages are upgraded, httpd WSGI* configuration are repeated twice, and httpd refuses to start. After packstack installation, WSGI configuration is shipped into 15-horizon_vhost.conf. Apparently it should be also in /etc/httpd/conf.d/openstack-dashboard.conf, shipped with openstack-dashboard, but this file seems to be removed during the installation (?): # rpm -Va openstack-dashboard missing c /etc/httpd/conf.d/openstack-dashboard.conf SM5....T. c /etc/openstack-dashboard/local_settings S.5....T. /usr/share/openstack-dashboard/openstack_dashboard/local/local_settings.pyc .......T. /usr/share/openstack-dashboard/static/dashboard/css/79750394898d.css .......T. /usr/share/openstack-dashboard/static/dashboard/css/b321bb0b3ce5.css .......T. /usr/share/openstack-dashboard/static/dashboard/js/0272dc9e5c21.js .......T. /usr/share/openstack-dashboard/static/dashboard/js/b28ee7422312.js ..5....T. /usr/share/openstack-dashboard/static/dashboard/manifest.json .M....... /var/log/horizon Packages installed though packstack --allinone: openstack-dashboard-2014.1-7.el7ost.noarch python-django-horizon-2014.1-7.el7ost.noarch => When the packages are upgraded to the latest version, the removed file (openstack-dashboard.conf) appears again, the WSGI configuration is repeated and httpd does not start anymore.
