1.生成新的MAC地址
2.查看ip
[root@localhost ~]# ifconfig
eth1 Link encap:Ethernet HWaddr 00:50:56:23:B0:4F
inet addr:192.168.146.130 Bcast:192.168.146.255 Mask:255.255.255.0
inet6 addr: fe80::250:56ff:fe23:b04f/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

TX packets:54 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:10975 (10.7 KiB) TX bytes:6571 (6.4 KiB)
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host

RX bytes:940 (940.0 b) TX bytes:940 (940.0 b)
[root@localhost ~]#
3.使用vim /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 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:31:32:0e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:23:b0:4f", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

~
4.根据ifconfig查看HWaddr 00:50:56:23:B0:4F除外的删除，就是还剩下的，(注：你们根据你们自己的定)
# 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 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:23:b0:4f", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
~
5.使用vim /etc/sysconfig/network-scripts/ifcfg-eth0修改成下面
[root@localhost ~]# cd /
[root@localhost /]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO="dhcp"
HWADDR="00:50:56:23:B0:4F"
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="2dbea590-a659-4e94-9626-f5f59dacde22"
IPADDR="192.168.146.130"
NETMASK="255.255.255.0"
GATEWAY="192.168.146.1"
6.service network restart重启网络
[root@localhost /]# service network restart
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: Active connection state: activating
Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/1
state: activated
Connection activated
[ OK ]
[root@localhost /]#
这样就可以了
# 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 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:23:b0:4f", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
