1、禁用網絡管理器

# chkconfig NetworkManager off # service NetworkManager stop 

2、創建用以橋接的虛擬網卡

# cd /etc/sysconfig/network-scripts  # cp ifcfg-eth0 ifcfg-br0 

注：修改之前做好備份啊，萬一有問題還可以還原！

3、編輯 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：最好切換到root帳戶操作，否則保存時可能會提示：E45: 'readonly' option is set (add ! to override)

4、編輯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：和你的電腦同一網段的IP地址GATEWAY：與你的電腦的默認網關相同

5、重新啟動網絡

# service network restart 

6、可能提示以下錯誤：

Bringing up interface eth0:  Device eth0 does not seem to be present,delaying initialization.                    [FAILED]

解決辦法：

首先，打開/etc/udev/rules.d/70-persistent-net.rules內容如下面例子所示：

# 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" 

記錄下，eth1網卡的mac地址00:0c:29:50:bd:17

接下來，打開/etc/sysconfig/network-scripts/ifcfg-eth0

# vi /etc/sysconfig/network-scripts/ifcfg-eth0

將 DEVICE="eth0"  改成  DEVICE="eth1"  ,

將 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址  HWADDR="00:0c:29:50:bd:17"

最后，重啟網絡

# service network restart

或者

# /etc/init.d/network restart

正常了。

7、第二天啟動后的尷尬

頭一天配置完成后是可以上網的，但當時沒有重啟系統測試，可能是有些配置沒有完全生效！
