openstack pike linuxbridge換成openvswitch
現(xiàn)有網(wǎng)絡節(jié)點的網(wǎng)絡方案為:
neutron ml2 type driver: vxlan
neutron ml2 mechanism driver : linuxbridge
neutron l2 agent: linuxbridge
改后的方案:
neutron ml2 type driver: vxlan
neutron ml2 mechanism driver : openvswitch
neutron l2 agent: openvswitch
在網(wǎng)絡節(jié)點和計算節(jié)點停止并刪除neutron-linuxbridge-agent
systemcat stop neutron-linuxbridge-agent
systemcat disable neutron-linuxbridge-agent
yum remove neutron-linuxbridge-agent
刪除linuxbridge agent
openstack work agent list 查看linuxbridgent agent對應的id
openstack work agent delete $id 刪除對應的id
在網(wǎng)絡節(jié)點和計算節(jié)點安裝neutron-openvswitch-agent
yum install -y openstack-neutron-openvswitch
在網(wǎng)絡節(jié)點添加br-ex網(wǎng)橋
ovs-vsctl add-br br-ex
br-ex 網(wǎng)橋綁定網(wǎng)卡
ifconfig eth0 0 && ovs-vsctl add-port br-ex eth0
為了開啟生效在/etc/rc.local加上如下配置
ovs-vsctl add-port br-ex eth0
ifconfig br-ex 192.168.100.114/24 (ip根據(jù)時間情況改)
網(wǎng)上有說改/etc/sysconfig/network-scripts下的文件,親測了下在centos7.4環(huán)境下,network重啟失敗
所以建議在/etc/rc.local里添加配置。并改/etc/rc.local為可執(zhí)行權限
chmod +x /etc/rc.d/rc.local
