Change the name of the network card of centos7 to eth0
Because I often switch between centos6 and centos7 systems, I feel that the network card name of centos7 is too long and inconvenient, so I want to make it the same as 6.
If you want to change the name of the network card to the same eth0,eth2 as 6, do the following
1.#cd / etc/sysconfig
two。 Add the following sentence to the longest line
# vim grub
Net.ifnames=0 biosdevname=0
3.#grub2-mkconfig-o / boot/grub2/grub.cfg
4. Rename the original network card name
# cd / etc/sysconfig/network-scripts
# mv ifcfg-enoXXXXXXXX ifcfg-eth0
5. Change the name of NAME,DEVICE in ifcfg-eth0 to eth0.
NAME=eth0
DEVICE=eth0
6.reboot and check to find that it has become the eth0 we want
