第一项： 克隆

 

方法一、

1.注释掉eth0这一行，将第二条配置中的eth1改成eth0

vi /etc/udev/rules.d/70-persistent-net.rules
# PCI device 0x8086:0x100f (e1000)
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:55:c1:c4", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"     #<==注释该行
 
 
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:33:c1:47", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"     #<==将eth1改为eth0

 2.删除vi /etc/sysconfig/network-script/ifcfg-eth0下的HWADDR

vi /etc/sysconfig/network-script/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp

 3.shutdown -r now重启生效

 

 

方法二：

1.ifconfig -a 查看所有网卡信息

2.更改eth1网卡信息

vi /etc/sysconfig/network-script/ifcfg-eth0
DEVICE=eth1      #<==将eth0改为eth1
TYPE=Ethernet
HWADDR=00:0C:29:33:C1:47    #<==更改为eth1的mac地址
ONBOOT=yes
BOOTPROTO=dhcp

 3.重启网卡生效

service network restart
