Configuring OpenStack as Ceph clients

OpenStack nodes should be configured as Ceph clients in order to access the Ceph cluster. To do this, install Ceph packages on OpenStack nodes and make sure it can access the Ceph cluster.

How to do it…

In this recipe, we are going to configure OpenStack as a Ceph client, which will be later used to configure cinder, glance, and nova:
