7. Add a networking service

Controller Node:

1. sudo vi /etc/nova/nova.conf

[DEFAULT]

...

network_api_class = nova.network.api.API

security_group_api = nova

2. sudo service nova-api restart && sudo service nova-scheduler restart && sudo service nova-conductor restart

 

Compute Node:

1. sudo apt-get install nova-network nova-api-metadata

2. sudo vi /etc/nova/nova.conf

[DEFAULT]

...

network_api_class = nova.network.api.API

security_group_api = nova

firewall_driver = nova.virt.libvirt.firewall.IptablesFirewallDriver

network_manager = nova.network.manager.FlatDHCPManager

network_size = 254

allow_same_net_traffic = False

multi_host = True

flat_injected = False

send_arp_for_ha = True

share_dhcp_address = True

force_dhcp_release = True

flat_network_bridge = br100

flat_interface = eth1

public_interface = eth0

 

3.

sudo service nova-network restart

sudo service nova-api-metadata restart

Create initial network (Controller Node):

1. source admin-openrc.sh

2. 为实例创建可以被分配的IP Pool

nova network-create demo-net --bridge br100 --multi-host T --fixed-range-v4 172.52.17.0/24

 

3. 生成net-id供第十四步中使用

nova net-list

4. 创建Floating IP以使外部网络可以访问到实例

sudo nova-manage floating create --pool nova --ip_range 192.168.0.0/24

sudo nova-manage floating list
