测试网桥

1 2 3 4 5 6 7 8 9 10 11 12 13

systemctl stop NetworkManager.service systemctl disable NetworkManager.service ovs-vsctl add-br  br0 ovs-vsctl add-port br0 eth1 ovs-vsctl show d8fb371e-5b17-40af-a358-9a207b4e44e0     Bridge "br0"         Port "br0"             Interface "br0"                 type: internal         Port "eth1"             Interface "eth1"     ovs_version: "2.5.0"

##修改前

1 2 3 4 5 6

[iyunv@hequan ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1   DEVICE=eth1 ONBOOT=yes BOOTPROTO=static IPADDR=115.29.107.17 NETMASK=255.255.252.0

##修改后

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

[iyunv@hequan ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1   DEVICE=eth1 DEVICETYPE=ovs TYPE=OVSPort OVS_BRIDGE=br0 ONBOOT=yes BOOTPROTO=nono [iyunv@hequan ~]# cat /etc/sysconfig/network-scripts/ifcfg-br0 DEVICE=br0 DEVICETYPE=ovs TYPE=OVSBridge ONBOOT=yes BOOTPROTO=none IPADDR=115.29.107.17 NETMASK=255.255.252.0

重启

1 2	[iyunv@hequan ~]# systemctl restart network.service [iyunv@hequan ~]# /etc/init.d/openvswitch restart    ##可以用外网连接了

重启后，还是可以生效的
