一：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:89:97", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x1022:0x2000 (pcnet32)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:17", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"




二：记录下，eth1网卡的mac地址00:0c:29:50:bd:17



三：编辑/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"




四：重启网卡和网络服务

/sbin/ifdown eth0

/sbin/ifup eth0


service network restart
