With OpenStack Identity Service (Keystone) installed and configured, we now need to tell our OpenStack Compute Service (Nova) that it can be used to authenticate users and services.
To begin with, ensure that you’re logged in to our OpenStack compute and Controller hosts. If you did this through Vagrant, you can log in with the following commands in separate shells:
vagrant ssh controller vagrant ssh compute-01
Configuring the authentication mechanism in our OpenStack Compute sandbox environment is achieved with the following steps:
We first ensure that our OpenStack Compute host has the required
python-keystonepackage installed, if this host is a standalone compute host:sudo apt-get update sudo apt-get install python-keystone
