• 配置(基于 Provider networks)

1. 配置
   vi /etc/neutron/plugins/ml2/linuxbridge_agent.ini

[linux_bridge]
physical_interface_mappings = provider:enp3s0

[vxlan]
enable_vxlan = false

[securitygroup]
...
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

• 配置和啟動

1. 配置
   vi /etc/nova/nova.conf

username = neutron
password = 123456

2. 啟動
   systemctl restart openstack-nova-compute.service
systemctl enable neutron-linuxbridge-agent.service
systemctl start neutron-linuxbridge-agent.service

• 驗證（Controller 節點）

1. 登錄：. admin-openrc
2. 查看列表：openstack network agent list

4. 重啟
   systemctl restart httpd.service memcached.service
5. 測試
   http://192.168.0.201/dashboard

15.啟動一個實例

• 創建虛擬網絡（基于 provider networks）

1. 登錄. admin-openrc
2. 創建 network
openstack network create --share --external --provider-physical-network provider --provider-network-type flat provider
   
   image.png
3. 創建子網

openstack subnet create --network provider --allocation-pool start=192.168.0.220,end=192.168.0.229 --dns-nameserver 192.168.0.1 --gateway 192.168.0.1 --subnet-range 192.168.0.0/24 provider

• 創建 flavor

1. 登錄. admin-openrc
2. 創建：
   openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano

• 創建 key pair

1. 登錄：. demo-openrc
2. 創建：
   ssh-keygen -q -N ""
   回車
   openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
3. 查看
   openstack keypair list

• 配置安全組

1. 登錄：. demo-openrc
2. ICMP
openstack security group rule create --proto icmp default
3. SSH
openstack security group rule create --proto tcp --dst-port 22 default

• 創建一個 instance
