Change openstack pike linuxbridge to openvswitch
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
