OpenStack Mitaka (三鷹) : Cinder 設定#1 (Control ノード)2016/05/08

OpenStack Block Storage（Cinder）をインストールします。

ここでは、以下のように、Keystone/Glance/Nova API インストール済みの Control ノードに新たに Cinder API をインストールし、 Block Storage Service ノードに Cinder-Volume をインストールして設定します。 ( 例として役割ごとに分けていますが、All in One 構成にすることももちろん可能です )

                                      +------------------+

                                      +------------------+

	ここでは、Control ノードの設定をします。
[1]	Control ノードの Keystone に Cinder 用のユーザー等々を登録しておきます。
