1、禁用网络管理器
# chkconfig NetworkManager off # service NetworkManager stop
2、创建用以桥接的虚拟网卡
# cd /etc/sysconfig/network-scripts # cp ifcfg-eth0 ifcfg-br0
3、编辑 ifcfg-br0
# vi ifcfg-br0 DEVICE="br0" TYPE="Bridge" ONBOOT="yes" BOOTPROTO=static IPADDR=192.168.1.17 PREFIX=24 GATEWAY=192.168.1.1 DNS1=202.106.46.151
DNS2=202.106.0.20 DELAY=0
注意：最好切换到root帐户操作，否则保存时可能会提示：E45: 'readonly' option is set (add ! to override)
4、编辑ifcfg-eth0
# vi ifcfg-eth0 DEVICE="eth0" NM_CONTROLLED="yes" ONBOOT=yes TYPE=Ethernet BRIDGE="br0" BOOTPROTO=none IPADDR=192.168.1.17 PREFIX=24 GATEWAY=192.168.1.1 DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="System eth0" UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03 DNS1=202.106.46.151
DNS2=202.106.0.20
HWADDR=00:1E:67:07:EC:30
IPADDR：和你的电脑同一网段的IP地址
GATEWAY：与你的电脑的默认网关相同
5、重新启动网络
# service network restart
6、可能提示以下错误：
Bringing up interface eth0: Device eth0 does not seem to be present,delaying initialization. [FAILED]
解决办法：
首先，打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示：
# vi /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8f:89:9
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:1
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
记录下，eth1网卡的mac地址00:0c:29:50:bd:17
接下来，打开/etc/sysconfig/network-scripts/ifcfg-eth0
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
将 DEVICE="eth0" 改成 DEVICE="eth1" ,
将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址 HWADDR="00:0c:29:50:bd:17"
最后，重启网络
# service network restart
或者
# /etc/init.d/network restart
正常了。
