OpenStack Kilo : Configure Cinder(Control Node)

2015/06/16

Install and Configure OpenStack Block Storage (Cinder).

For this example, Install Cinder API Server on Control Node which Keystone/Glance/Nova API are already installed, and Install Cinder-Volume on Block Storage Service Node. ( it's possible to install on a server as All-in-One, though, if you want )
