虚拟机克隆CentOS后的网卡配置

来源：互联网发布：恒大社会招聘网络面试编辑：程序博客网时间：2024/05/25 05:37

由于克隆虚拟机，vmware只是修改了虚拟机的名字等信息，并没有修改虚拟硬盘中的任何信息，导致克隆后网卡的MAC地址和操作系统中记录的mac地址不符，导致eth0启动不起来。操作系统记录了一个新网卡的添加，新网卡的名字eth1，mac地址就是vmware分配给的新的mac地址

解决方法：

修改 /etc/udev/rules.d/70-persistent-net.rules 文件
删除掉关于 eth0 的信息。修改第二条 eth1 的网卡的名字为 eth0.

修改 /etc/sysconfig/network-scripts/ifcfg-eth0 中mac地址为 /etc/udev/rules.d/70-persistent-net.rules 修改后的eth0的mac地址。
