OpenStack Yoga : Neutron 設定 #22022/04/29 |
|
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、Open Virtual Network (OVN) を利用した 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。
eth0|10.0.0.30
+-----------+-----------+
| [ dlp.srv.world ] |

| MariaDB RabbitMQ |
| Memcached httpd |
| Keystone Glance |
| Nova API/Compute |
| Neutron Server |
| Open vSwitch |
| OVN Metadata Agent |
| OVN-Controller |
