[[email protected] ~]# cd /etc/sysconfig/network-scripts/ [[email protected] network-scripts]# cp ifcfg-eth0 ifcfg-br0 [[email protected] network-scripts]# vi ifcfg-eth0 //改成这样 DEVICE=eth0 HWADDR=00:0C:29:06:A2:35 TYPE=Ethernet UUID=34b706cc-aa46-4be3-91fc-d1f48c301f23 ONBOOT=yes BRIDGE=br0 NM_CONTROLLED=yes BOOTPROTO=static [[email protected] network-scripts]# vi ifcfg-br0 //改成这样 DEVICE=br0 TYPE=Bridge ONBOOT=yes BOOTPROTO=static IPADDR=192.168.216.131 NETMASK=255.255.255.0 GATEWAY=192.168.216.2 DNS=8.8.8.8 [[email protected] network-scripts]# service network restart 正在关闭接口 eth0： bridge br0 does not exist!

操作遇到以下问题：！！！！
[[email protected] network-scripts]# service network restart /* 这里如果10秒以上没有反应，那就需要去虚拟机检查。 登陆--〉 ifconfig 查看eth0是否存在 --〉 ping www.baidu.com （是否通） --〉 ping 网关 （不通，则配置有问题） --〉 （通） 检查ifcfg-eth0 ifcfg-br0是否写对 */
