CentOS-CentOS6.4下修改网卡名称 eth2修改为eth0

Vmware对虚拟机复制之后100%的网卡名称会变化，一般变化为eth2，原因为复制的虚拟机会重新生成mac地址。

如下：

[[email protected]-222-Oracle12~]# ifconfig -a

修改办法如下：

 

vi/etc/udev/rules.d/70-persistent-net.rules

把NAME="eth2" 修改为NAME="eth0"，并将多余的记录删掉。

重启即可

举例如下：

以前的文件内容为

# 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}=="00:0c:29:21:3e:50",ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

 

# PCI device 0x8086:0x100f (e1000)

SUBSYSTEM=="net", ACTION=="add",DRIVERS=="?*", ATTR{address}=="00:0c:29:79:b9:9c",ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

 

# PCI device 0x8086:0x100f (e1000)

SUBSYSTEM=="net", ACTION=="add",DRIVERS=="?*", ATTR{address}=="00:0c:29:55:60:17",ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"

 

修改后的文件内容为

# 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.
