OpenStack Stein : ネットワークを構成する2019/05/16 |
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 | | 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。 |
# ブリッジ追加 [root@dlp ~(keystone)]# ovs-vsctl add-br br-eth1 # 追加したブリッジのポートにeth1を追加 [root@dlp ~(keystone)]# ovs-vsctl add-port br-eth1 eth1

bridge_mappings = physnet1:br-eth1
