1,安装桥接软件包
yum install bridge-utils
2,修改文件/etc/sysconfig/network-scropts/ifcfg-eth0;
BRIDGE=br0
删除下面
ONBOOT=yes IPADDR=10.0.0.23 NETMASK=255.255.255.0 GATEWAY=10.0.0.1 DNS1=61.134.1.4
3,建立文件/etc/sysconfig/network-scripts/ifcfg-br0;
BEVICE=br0 BOOTPROTO=none TYPE=Bridge ONBOOT=yes DELAY=0 IPADDR=10.0.0.23 NETMASK=255.255.255.0 GATEWAY=10.0.0.1 DNS1=61.134.1.4 (注意DNS只有一个也要写DNS1,不能直接写DNS)
4,重启;
5,确认网桥是否存在;
/usr/sbin/brct1 show
若成功则显示
