OpenStack Newton : Cinder 設定#1 (Control ノード)
2016/10/26
 
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 )
                                      +------------------+
                             10.0.0.50| [ Storage Node ] |
+------------------+            +-----+   Cinder-Volume  |
| [ Control Node ] |            | eth0|                  |

+------------------+            +-----+   Nova Compute   |
                             10.0.0.51|                  |
                                      +------------------+

 
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。
