Hello dear friends. I wanted to report a misconfiguration in the official documentation of OpenStack nova. I put the link at the end of this message.
In the [service_user] section, they should place the port number of keystone which is 5000 but it has been mistakenly omitted and caused a lot of trouble and error during the installation procedure of the nova on both controller and compute node.
