during nova service install ,an unneeded httpd conf bug fix causes openstack client cli crash

[pini]

- [X] This doc is inaccurate in this way:

Hi ,

Please MOVE the quoted section below from :

https://docs.openstack.org/ocata/install-guide-rdo/nova-controller-install.html#install-and-configure-components

To:

https://docs.openstack.org/ocata/install-guide-rdo/nova-verify.html (before no.5).

reason:

When the patch is done at the original location it breaks the openstack client cli , breaking openstack configuration cli (openstack user create ...etc.):

details further down ...

"""

    Due to a packaging bug, you must enable access to the Placement API by adding the following configuration to /etc/httpd/conf.d/00-nova-placement-api.conf:

    <Directory /usr/bin>
       <IfVersion >= 2.4>
          Require all granted
       </IfVersion>
       <IfVersion < 2.4>
          Order allow,deny
          Allow from all
       </IfVersion>
    </Directory>

    Restart the httpd service:

    # systemctl restart httpd

"""

when you do add this <directory> section to the named httpd conf file. it causes the following error on all openstack client cli :

#openstack endpoint list;openstack catalog list
Discovering versions from the identity service failed when creating the password plugin. Attempting to determine version from URL.
Internal Server Error (HTTP 500)
Discovering versions from the identity service failed when creating the password plugin. Attempting to determine version from URL.
Internal Server Error (HTTP 500)

Bug suggested solution :
Please MOVE the mentioned section to https://docs.openstack.org/ocata/install-guide-rdo/nova-verify.html (before no.5 - nova-status upgrade check).
Adding the httpd section patch at this step works flawlessly.

The solution to the original bug placement as is :
Undo && redo the following part of the identity service install :

The content in question is being moved to the nova repository, see https://review.openstack.org/#/c/477488/.

I'm also not sure about the suggested fix, the nova placement configuration is not a verification step.

This bug is from 2017 and affects only older releases: Rocky, Queens, Pike so I'm setting the importance to Low.

Note: For ocata, this text is in the openstack-manuals repo (not nova).

Change abandoned by Harshavardhan Metla (<email address hidden>) on branch: master
Review: https://review.opendev.org/737215
Reason: since the change needs to be done on openstack-manuals and older verions
