CentOS虚拟机克隆后网卡配置问题及解决。

CentOS虚拟机克隆,物理地址会冲突,于是自动新建了网卡eth1,无法启动网卡。

解决办法:  www.linuxidc.com 

方式1:

1)修改/etc/sysconfig/network-scripts/ifcfg-eth0 为 /etc/sysconfig/network-scripts/ifcfg-eth1

2)配置/etc/sysconfig/network-scripts/ifcfg-eth1

# 修改为eth1

DEVICE="eth1"

BOOTPROTO="static"

# 硬件地址取自eth1(通过“ifconfig -a”获取)

HWADDR="00:0C:29:91:42:2C"

MTU="1500"

NM_CONTROLLED="yes"

ONBOOT="yes"

IPADDR=192.168.152.101

NETMASK=255.255.255.0

GATEWAY=192.168.152.2

3)service network restart

方式2:

1)修改/etc/udev/rules.d/70-persistent-net.rules

拷贝eth1的硬件地址到eth0

删除eth1信息

2)配置/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"

BOOTPROTO="static"

HWADDR="00:0C:29:91:42:2C"

MTU="1500"

NM_CONTROLLED="yes"

ONBOOT="yes"

IPADDR=192.168.152.101

NETMASK=255.255.255.0

GATEWAY=192.168.152.2

3)reboot

方式3(未测试):

1)删除/etc/udev/rules.d/70-persistent-net.rules

2)配置/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"

BOOTPROTO="static"

HWADDR="00:0C:29:91:42:2C"

MTU="1500"

NM_CONTROLLED="yes"

ONBOOT="yes"

IPADDR=192.168.152.101

NETMASK=255.255.255.0

GATEWAY=192.168.152.2

3)reboot
