在对VMWare的虚拟机进行复制之后，新的虚拟机会出现网络无法启动的问题，在实体机当中还没遇到，不过解决办法应该是通用的。

1、首先重命名 /etc/udev/rules.d/70-persistent-net.rules文件，并重启虚拟机。

Shell

cd /etc/udev/rules.d/

mv 70-persistent-net.rules 70-persistent-net.rules.bak

reboot

3

cd/etc/udev/rules.d/

mv70-persistent-net.rules70-persistent-net.rules.bak

reboot

重启后， 机器自己重新生成/etc/udev/rules.d/70-persistent-net.rules 文件，内容如下：

# 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:29:50:bd:1

7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

SUBSYSTEM=="net",ACTION=="add",DRIVERS=="?*",ATTR{address}=="00:0c:29:50:bd:1

7",ATTR{type}=="1",KERNEL=="eth*",NAME="eth1"

记下文件中显示的Mac地址信息以及网卡名称eth1，一会要用到。

2、修改网卡的文件名称。

mv /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1

1

mv/etc/sysconfig/network-scripts/ifcfg-eth0/etc/sysconfig/network-scripts/ifcfg-eth1

默认的网卡名称为eth0，对应的文件名是ifcfg-eth0，需要根据刚才文件的内容将文件名改为ifcfg-eth1。

3、编辑ifcfg-eth1文件内容

DEVICE="eth1" #修改网卡名称

BOOTPROTO=dhcp

HWADDR="00:0C:29:50:bd:17" ＃把地址改成刚才看到的MAC地址

NM_CONTROLLED="yes"

ONBOOT="yes"

DEVICE="eth1"#修改网卡名称

BOOTPROTO=dhcp

HWADDR="00:0C:29:50:bd:17"＃把地址改成刚才看到的MAC地址

NM_CONTROLLED="yes"

ONBOOT="yes"

4、重新启动网络服务

service network restart

1

servicenetworkrestart

重启后系统会输出提示信息：

Shutting down interface eth1: [ OK ]

Shutting down loopback interface: [ OK ]

Bringing up loopback interface: [ OK ]

Bringing up interface eth1:

Determining IP information for eth1... done.

[ OK ]

Shuttingdowninterfaceeth1:[OK]

Shuttingdownloopbackinterface:[OK]

Bringinguploopbackinterface:[OK]

Bringingupinterfaceeth1:

[OK]

网络服务重启成功。

5、查看获取到的IP地址

ifconfig

1

ifconfig

可以看到系统输出了eth1网卡的相关信息，包括MAC地址、IP、子网掩码等内容。

成功获取到了IP地址，这样虚拟机就可以和其他服务器进行通信了。
