ขั้นตอนการ สร้าง vlan และ config
โดย service ที่ รันในแต่ละโหนดจะเป็นดังภาพ
+ Packet install on compute node
|
1 2 3 |
apt-get install neutron-plugin-ml2 neutron-plugin-openvswitch-agent |
Service run
|
1 2 3 4 |
service openvswitch-switch restart service neutron-plugin-openvswitch-agent restart |
+ Packet install on network node
|
1 2 3 4 |
apt-get install neutron-plugin-ml2 neutron-plugin-openvswitch-agent \ neutron-l3-agent neutron-dhcp-agent neutron-metadata-agent |
Service run
|
1 2 3 4 5 6 7 |
# service neutron-plugin-openvswitch-agent restart # service neutron-l3-agent restart # service neutron-dhcp-agent restart # service neutron-metadata-agent restart # service openvswtich restart |
+ Packet install on controller node
|
1 2 3 |
apt-get install neutron-server neutron-plugin-ml2 python-neutronclient |
Service run
|
1 2 3 |
service neutron-server restart |
Config ส่วนใหญู่จะตาม เอกสาร openstack install แต่เปลี่ยน config ใน /etc/neutron/plugins/ml2/ml2_conf.ini เพื่อปรับ รูปแบบ network.
