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。

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
