重启网络服务

[root@node-1 ~]# systemctl restart openstack-nova-api.service
[root@node-1 ~]# systemctl restart neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service

启动layer-3服务

[root@node-1 ~]# systemctl enable neutron-l3-agent.service
Created symlink /etc/systemd/system/multi-user.target.wants/neutron-l3-agent.service → /usr/lib/systemd/system/neutron-l3-agent.service.
[root@node-1 ~]# systemctl start neutron-l3-agent.service

启动后dhcp-agent报错

开启selinux权限
# setsebool -P neutron_can_network on
# setsebool -P haproxy_connect_any on
# setsebool -P daemons_enable_cluster_mode on

最好在一开始就关闭selinux，不然会有各种问题
