OpenStack Zed : Neutron 設定 #22023/06/27 |
OpenStack Network Service(Neutron)をインストールします。
当例では以下のような環境を例に Neutron ネットワークを設定します。
以下のように All in One 構成ではなく、ノードを役割ごとに分離する場合、または Nova Compute ノードを他ホストに分離して構成している場合等の Neutron サービスの構成はこちらを参照して設定ください。
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。
当例では ML2 プラグインを選択して設定します。( バックエンドは Open vSwitch を選択 ) eth0|10.0.0.30 +-----------+-----------+ | [ dlp.srv.world ] | | (Control Node) | | | | MariaDB RabbitMQ | | Memcached Nginx | | Keystone httpd | | Glance Nova API | | Nova Compute | | Neutron Server | | Neutron Metadata | | Neutron L2/L3 Agent | | Open vSwitch | +-----------------------+ |
