OpenStack Dalmatian : Neutron 設定 (Control ノード)2024/10/04 |
|
OpenStack Network Service（Neutron）の設定です。
当例では All in One 構成ではなく、以下のようにノードを役割ごとに分離した 3 ノード構成で設定します。
------------+--------------------------+--------------------------+------------
| | |
eth0|10.0.0.30 eth0|10.0.0.50 eth0|10.0.0.51
+-----------+-----------+ +-----------+-----------+ +-----------+-----------+
| [ dlp.srv.world ] | | [ network.srv.world ] | | [ node01.srv.world ] |
| (Control Node) | | (Network Node) | | (Compute Node) |
| | | | | |
| MariaDB RabbitMQ | | Neutron L2/L3 Agent | | Libvirt |
| Memcached Nginx | | Neutron Metadata | | Nova Compute |
| Keystone httpd | | Open vSwitch | | Neutron L2 Agent |
| Glance Nova API | | | | Open vSwitch |
| Neutron Server | | | | |
| Neutron Metadata | | | | |

こちらを参照して Control ノードで Keystone への Neutron ユーザー登録やデータベース作成を実施しておきます。 |
| [2] | Control ノードに Neutron Server をインストールします。 |
