openstack newton linuxbridge 改成 ovs

最近搭建了一个all in one 的 openstack newton 版，安装官方文档做用的是linuxbridge。已经老版玩的时候都是用的ovs，趁比较闲的时候也将N版改造一下

官方文档

http://docs.openstack.org/liberty/networking-guide/scenario-provider-ovs.html

下面只列出比较重要的文件，官方有文档，这次参考L版的文档来操作的

安装包yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch

控制节点

/etc/neutron/neutron.conf

[DEFAULT]
verbose = True
core_plugin = ml2

/etc/neutron/plugins/ml2/ml2_conf.ini

[DEFAULT]
[ml2]
type_drivers = flat,vlan,vxlan
tenant_network_types = vxlan
mechanism_drivers = openvswitch,l2population
extension_drivers = port_security
[ml2_type_flat]
flat_networks = provider
[ml2_type_geneve]
[ml2_type_gre]
[ml2_type_vlan]
[ml2_type_vxlan]
vni_ranges = 1:1000
[securitygroup]
enable_ipset = True

/etc/neutron/plugins/ml2/openvswitch_agent.ini

[DEFAULT]
[ovs]
local_ip=192.168.0.228
bridge_mappings=provider:br-ex
[agent]
tunnel_types=gre,vxlan
l2_population=True
prevent_arp_spoofing=True
[securitygroup]
firewall_driver=iptables_hybrid
enable_security_group=True

/etc/neutron/dhcp_agent.ini

[DEFAULT]
dnsmasq_config_file = /etc/neutron/dnsmasq-neutron.conf
interface_driver=neutron.agent.linux.interface.OVSInterfaceDriver
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = True
[AGENT]

创建桥，这个跟之前的J版本什么都一样

ovs-vsctl add-br br-ext

ovs-vsctl add-port br-ext  网卡

重启服务器

• neutron Server
• Open vSwitch agent
• DHCP agent

计算节点

/etc/neutron/plugins/ml2/openvswitch_agent.ini

[DEFAULT]
[ovs]
bridge_mappings=provider:br-ex
[agent]
prevent_arp_spoofing=True
[securitygroup]
firewall_driver=iptables_hybrid
enable_security_group=True

开启ovs

重复增加端口步骤

ovs-vsctl add-br br-ext

ovs-vsctl add-port br-ext  网卡

启动Open vSwitch agent

检查一下

然后按照N版官方文档创建网络即可
