Due to the cloning of the virtual machine, I found that the MAC addresses of the cloned machine and the cloned machine are the same. Now I will introduce the configuration steps of the network card in Linux. The Linux I use is CentOS release 6.9 (Final)
1. The root user edits the /etc/udev/rules.d/70-persistent-net.rules file, finds the network card with a duplicate mac address and deletes it (eth0 here), remember the mac of the newly generated network card eth1 Address, will be used later, save and exit
# vi /etc/udev/rules.d/70-persistent-net.rules
2 , edit /etc/sysconfig/network-scripts/ifcfg-eth0, and change the HWADDR address to the newly generated mac address 00:50:56:36:16:72
# vi /etc/ sysconfig/network-scripts/ifcfg-eth0
3. Restart the system to make the previous modifications take effect
# reboot
