One: rename it to eth0:

After installation, a look at the name of the network card, all into a long string of numbers enoxxxxxxxxx.

If you still want to continue to change to the previous eth0,eth1 naming, execute the following command:

Vim / etc/sysconfig/grub

Add a net.ifnames=0 biosdevname=0 statement, as shown in the red box below

Grub2-mkconfig-o / boot/grub2/grub.cfg

Mv / etc/sysconfig/network-scripts/ifcfg-enoxxxxxx / etc/sysconfig/network-scripts/ifcfg-eth0

/ etc/sysconfig/network-scripts/ifcfg-eth0

Change the previous name=en0xxxxx to name=eth0 device and also to device=eth0

The restart of reboot is complete.

Second: do you want to add the network card eth1 again? :

All kinds of google, baidu, and restart just don't work:

To sum up, if the hwaddr and the real mac address in centos7 are not correct, restart the network service to report a lsb error.

You can use ifconfig or ip addr to check the specific mac address.

Finally, it is found that when the virtual machine is turned on, the network card that is not in effect will be deleted with the setting of vmware, and then another network card will be added. The virtual machine will be refreshed automatically, and the newly added network card will appear with ifconfig. At this point, you only need to copy a / etc/sysconfig/network-scripts/ifcfg-eth1 file.
