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.
In this recipe, we are going to configure OpenStack as a Ceph client, which will be later used to configure cinder, glance, and nova:
ceph-node1to install Ceph binaries on
ceph-deploy, as we have done earlier in Chapter 1, Ceph – Introduction and Beyond. To do this, we should set up ssh password-less login to
os-node1. The root password is again the same (
$ vagrant ssh ceph-node1 $ sudo su - # ping os-node1 -c 1 # ssh-copy-id root@os-node1
