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。

、删除/etc/udev/rules.d/
70
-persistent-net.rules文件，重启系统

、如果上面的不起作用
(

), ifconfig 查看HWADDR的值
(

), /etc/sysconfig/network-script/ifcfg-eth1中修改ifconfig中查出的HWADD
