OpenStack Grizzly - Swift 設定#2 (プロキシノード)2013/08/23 |
|
OpenStack Object Storage（Swift）の設定です。
Swift は、認証ノード、プロキシノード、ストレージノードで構成されます。
これまでの例では Keystone, Glance, Cinder, Nova, Horizon を全て一つのサーバーにインストールする All-in-One 構成で設定してきましたが、 Swift の設定は以下のようにノードごとにサーバーを用意して、計5台を使って設定してみることにします。 (構築済みの All-in-One サーバーを認証ノードとして利用することにします)
|
+------------+ | +-----------+
| Auth Node |10.0.0.30 | 10.0.0.31| Proxy |
| (Keystone) |------------+------------| Node |
+------------+ | +-----------+
|
+------------------------+-----------------------+
| | |
|10.0.0.51 |10.0.0.52 |10.0.0.53
+-----------+ +-----------+ +-----------+
| Storage | | Storage | | Storage |
| Node1 |------------| Node2 |-----------| Node3 |
+-----------+ +-----------+ +-----------+

ここではプロキシノードの設定をします。
