Modify the network card ens33 to eth0
When using RHEL and Centos7, I found that the network card name has changed to EnoX, which is quite strange. Now change it back to the old name eth0 which looks pleasing to the eye.
- Back up the /etc/sysconfig/Change the network card name ens33 to eth0 under rhel and centos7 file
cp /etc/sysconfig/Change the network card name ens33 to eth0 under rhel and centos7 /etc/sysconfig/Change the network card name ens33 to eth0 under rhel and centos7.bak
- Edit /etc/sysconfig/Change the network card name ens33 to eth0 under rhel and centos7 file
vim /etc/sysconfig/Change the network card name ens33 to eth0 under rhel and centos7
Addnet.ifnames=0 biosdevname=0
within the double quotes after GRUB_CMDLINE_LINUX As shown in the figure after adding, the order within the quotation marks has no effect
Pay attention to the spaces between each parameter.
- Rebuild the GRUB configuration file
Change the network card name ens33 to eth0 under rhel and centos72-mkconfig -o /boot/Change the network card name ens33 to eth0 under rhel and centos72/Change the network card name ens33 to eth0 under rhel and centos7.cfg
- Back up the network card configuration file and change the network card file to eth0
cp /etc/sysconfifg/network-scripts/ifcfg-ens33 /etc/sysconfifg/network-scripts/ifcfg-ens33.bakmv /etc/sysconfifg/network-scripts/ifcfg-ens33 /etc/sysconfifg/network-scripts/ifcfg-eth0
ens33 may be different from yours. To be specific, check your own ensx with ifconfig first.
- Edit the /etc/sysconfig/network-scripts/ifcfg-eth0 file
vim /etc/sysconfig/network-scripts/ifcfg-eth0
Just change the NAME and DEVICE from the original ens33 to eth0.
- Just restart the system.
