[Bug 1799332] Re: Apache WSGI config shipping with Keystone is incompatible with Horizon

 

It is recommended keystone NOT be deployed on non-http/https (80/443)
ports. If you would like to use a Vhost on a different port it is up to
the deployer/installation tools to make that decision. The provided wsgi
file is intended to be opinionated on the best way to deploy keystone,
port 80/443 (standard ports) under the identity-prefix.

** Changed in: keystone
       Status: New => Invalid

Title:
  Apache WSGI config shipping with Keystone is incompatible with Horizon

Status in OpenStack Identity (keystone):
  Invalid

Bug description:
  In keystone/httpd/wsgi-keystone.conf, the following configuration is
  present:

  Alias /identity /usr/local/bin/keystone-wsgi-public
  <Location /identity>
      SetHandler wsgi-script
      Options +ExecCGI

      WSGIProcessGroup keystone-public
      WSGIApplicationGroup %{GLOBAL}
      WSGIPassAuthorization On
  </Location>

  However, it is both harmful and unnecessary.  The operative WSGI
  configuration for Keystone comes from the <VirtualHost
  *:5000>...</VirtualHost> section.  In fact, the commit which added the
  /identity endpoint described it as an documentation example:

  "Apache Httpd can be configured to accept keystone requests on all
  sorts of interfaces. The sample config file is updated to show
  how to configure Apache Httpd to also send requests on /identity
  and /identity_admin to keystone."

  Leaving it in place, however, causes conflicts when Horizon is
  concurrently installed:

  AH01630: client denied by server configuration: /usr/bin/keystone-
  wsgi-public

  ...in responses to Horizon URL's referencing '/identity'.  Therefore,
  I believe keeping this configuration snippet in the shipped WSGI
  configuration (as opposed to actual documentation) is a defect.
