openstack桥接-内外网设置

IT知识openstack

知识的价值不在于占有，而在于使用。这篇文章主要讲述openstack桥接-内外网设置相关的知识，希望能为你提供帮助。
在??https://blog.51cto.com/u_14814545/5169584??基础上,实现内外网
?控制端?
[root@control1 ~]# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini

[root@control1 ~]# grep "^[a-Z]" /etc/neutron/plugins/ml2/linuxbridge_agent.ini
physical_interface_mappings = internal:eth1,external:eth0
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
enable_vxlan = false

[root@control1 ~]# vim /etc/neutron/plugins/ml2/ml2_conf.ini
flat_networks = internal,external

重启neutron服务
[root@control1 ~]# systemctl restart neutron-linuxbridge-agent
[root@control1 ~]# systemctl restart neutron-server

【openstack桥接-内外网设置】?计算节点?
[root@node1 ~]# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[root@node1 ~]# grep "^[a-Z]" /etc/neutron/plugins/ml2/linuxbridge_agent.ini
physical_interface_mappings = internal:eth1,external:eth0
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
enable_vxlan = false

重启neutron服务
[root@node1 ~]# systemctl restart neutron-linuxbridge-agent
[root@node2 ~]# systemctl restart neutron-linuxbridge-agent

?控制端创建网络?
