OpenStack Train : ネットワークを構成する2019/10/25 |
|
仮想マシンインスタンスが利用するネットワークを構成します。
All in One 構成の Neutron サービス
または ノード毎に分離設定した Neutron サービスを事前に構成済みであることが前提です。
当例では、以下のような All in One 構成の環境を前提に、シンプルな FLAT タイプのネットワークを構成します。
また、ノードはネットワークインターフェースを二つ持っているものとします。
eth0|10.0.0.30
+-----------+-----------+
| [ Control Node ] |
| |
| MariaDB RabbitMQ |
| Memcached httpd |
| Keystone Glance |
| Nova API,Compute |
| Neutron Server |
| L2,L3,Metadata Agent |
+-----------+-----------+
eth1|(UP with no IP)

| [1] | Neutron サービスに追加設定します。 |
