OpenStack Havana - Neutron 利用例#12013/10/29 |
|
OpenStack Network Service（Neutron）による仮想ネットワークの設定です。
また、ネットワークノードと計算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ことを前提とし、
ここでは「eth1」に内部用ネットワークを割り当てるように設定します。（よって「eth1」のIPアドレスは事前に未割り当てにしてあります）
|
| [1] | まずは制御ノードでの設定です。 |
|
[root@dlp ~(keystone)]#
vi /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini # 最終行に追記
[OVS]
tenant_network_type = vlan network_vlan_ranges = physnet1 bridge_mappings = physnet1:br-eth1 /etc/rc.d/init.d/neutron-server restart Stopping neutron: [ OK ] Starting neutron: [ OK ] |
| [2] | ネットワークノード、および、計算ノードの両方で以下の設定をしてください。 |
|
[root@network ~(neutron)]# ovs-vsctl add-br br-eth1 # ブリッジ追加 [root@network ~(neutron)]# ovs-vsctl add-port br-eth1 eth1 # 追加したブリッジのポートにeth1を追加
[root@network ~(neutron)]#
vi /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini # 最終行に追記
[OVS]
tenant_network_type = vlan network_vlan_ranges = physnet1 bridge_mappings = physnet1:br-eth1 /etc/rc.d/init.d/neutron-openvswitch-agent restart Stopping neutron-openvswitch-agent: [ OK ] Starting neutron-openvswitch-agent: [ OK ] |
| [3] | ネットワークを作成します。作業場所はどこでもよいですが、ここでは計算ノード上で作業しています。 |
