增加部分

建立plugin.ini

ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

初始化neutron数据库
su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron

查看表

mysql -uneutron -pneutron -e "use neutron;show tables;"

重启服务并设置开机启动

systemctl restart openstack-nova-api neutron-server neutron-linuxbridge-agent neutron-dhcp-agent neutron-metadata-agent

systemctl enable neutron-server neutron-linuxbridge-agent neutron-dhcp-agent neutron-metadata-agent 1>&2

创建服务/端点

openstack service create --name neutron --description "OpenStack Networking" network
openstack endpoint create --region RegionOne network public http://192.168.3.220:9696
openstack endpoint create --region RegionOne network internal http://192.168.3.220:9696
openstack endpoint create --region RegionOne network admin http://192.168.3.220:9696
