This article mainly introduces "how to change the name of the network card in the Centos7 system". In the daily operation, I believe that many people have doubts about how to change the name of the network card in the Centos7 system. The editor consulted all kinds of materials and sorted out a simple and easy-to-use method of operation. I hope it will be helpful to answer the doubt of "how to change the name of the network card in the Centos7 system". Next, please follow the editor to study!

1. After the system has been installed, your network card may be named like this!

2. First, edit the configuration file vi / etc/sysconfig/network-scripts/ifcfg-eno16777736 of the network card and change the NAME entry to eth0.

3. Go ahead and rename the profile.

4. Then, disable the predictable naming convention. For this, you can pass the kernel parameters of "net.ifnames=0 biosdevname=0" at startup. This is done by editing / etc/default/grub and adding "net.ifnames=0 biosdevname=0" to the GRUBCMDLINELINUX variable.

Run the command grub2-mkconfig-o / boot/grub2/grub.cfg to regenerate the GRUB configuration and update the kernel parameters.

6. In fact, by step 5, the restart in ifconfig should have taken effect. According to the FAQ of Centos's official WIKI, if you have multiple interfaces and want to control their device names, instead of letting the kernel name it in its own way, it is necessary to create / etc/udev/rules.d/XXX-net.rules rules! So let's create rules here, too.

Note: the net rule name of the previous system is 70-persistent-net.rules, here I also define the rule according to that name!

7. Restart the system and verify!

Note: if the minimal installation of the Centos7 system does not have the ifconfig command, it can be solved by installing net-tools.

At this point, the study on "how to change the name of the network card in the Centos7 system" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
