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 (责任编辑:IT) |
