OpenStack Ocata : ネットワークを構成する2017/02/27 |
|
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 タイプのプロバイダー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 |eth1
| Keystone Glance +------
| Nova API,Compute |
| Neutron Server |
| L2,L3,Metadata Agent |
+-----------------------+
