OpenStack Newton : Neutron 設定#1 ( Control ノード )2016/11/17 |
OpenStack Network Service(Neutron)を設定します。
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 Neutron Server をインストールし、
Network ノードに DHCP Agent, L3 Agent, L2 Agent, Metadata Agent、Nova Compute インストール済みの Compute ノードに L2 Agent という構成で設定します。
( 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 )
なお、Neutron はプラグイン方式で、プラグインとして利用するソフトウェアを選択する必要があります。
ここでは例として ML2 プラグインを選択して設定します。( バックエンドは LinuxBridge を選択します )
| +------------------+ | +------------------------+ | [ Control Node ] | | | [ Network Node ] | | Keystone |10.0.0.30 | 10.0.0.50| DHCP Agent | | Glance |------------+------------| L3 Agent | | Nova API |eth0 | eth0| L2 Agent | | Neutron Server | | | Metadata Agent | +------------------+ | +------------------------+ eth0|10.0.0.51 +--------------------+ | [ Compute Node ] | | Nova Compute | | L2 Agent | +--------------------+ |
ここでは、Control ノードの設定をします。
