Shulou(Shulou.com)06/02 Report--

The network scheme of the existing network node is:

Neutron ml2 type driver: vxlan

Neutron ml2 mechanism driver: linuxbridge

Neutron l2 agent: linuxbridge

The revised plan:

Neutron ml2 type driver: vxlan

Neutron ml2 mechanism driver: openvswitch

Neutron l2 agent: openvswitch

Stop and delete neutron-linuxbridge-agent at network nodes and compute nodes

Systemcat stop neutron-linuxbridge-agent

Systemcat disable neutron-linuxbridge-agent

Yum remove neutron-linuxbridge-agent

Delete linuxbridge agent

Openstack work agent list to view the id corresponding to linuxbridgent agent

Openstack work agent delete $id deletes the corresponding id

Install neutron-openvswitch-agent on network nodes and compute nodes

Yum install-y openstack-neutron-openvswitch

Add a br-ex bridge to a network node

Ovs-vsctl add-br br-ex

Br-ex bridge binds network card

Ifconfig eth0 0 & & ovs-vsctl add-port br-ex eth0

To enable it to take effect, add the following configuration to / etc/rc.local

Ovs-vsctl add-port br-ex eth0

Ifconfig br-ex 192.168.100.114swap 24 (ip changed according to time)

It is said on the Internet that the file under the change / etc/sysconfig/network-scripts has been tested in person. Under the centos7.4 environment, the network restart failed.

So it is recommended to add configuration to / etc/rc.local. And change / etc/rc.local to executable permission

Chmod + x / etc/rc.d/rc.local
