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
