Uninstall use the command ifconfig command to check the network card

Confirm which network card you are using, and then uninstall all the other network cards. Run the command ifconfig Nic name down. Such as: ifconfig eth2 down

Run ifconfig again and you will find that the uninstalled network card is gone. Now you can ping the IP of the intranet to see if you can communicate with ping.

Delete redundant ifcfg-eth0.bak Centos system in VM after changing the network card or network card MAC address, there will be an eth0.bak configuration backup file solution: / etc/sysconfig/networking/devices directory, delete ifcfg-eth0.bak / etc/sysconfig/networking/profiles/default, delete ifcfg-eth0.bak / etc/sysconfig/network-scripts/, delete ifcfg-eth0.bak

Delete the redundant network cards (e.g. eth2) / etc/modprobe.conf in the Linux system, delete the alias eth2 XXXX / etc/sysconfig/networking/devices directory, delete the ifcfg-eth2 under the / etc/sysconfig/networking/profiles/default directory, delete the ifcfg-eth2 under the / etc/sysconfig/network-scripts/ directory, delete the ifcfg-eth0.bak

3. Check whether the network interface (eth0) is working properly / etc/modprobe.conf, this file must have: alias eth0 XXX / etc/sysconfig/hwconf, the configuration corresponding to eth0 in this file must also be correct / etc/sysconfig/network-scripts directory, there must be the configuration file of network interface: whether the configuration in ifcfg-eth0 / etc/sysconfig/network-scripts/ifcfg-eth0 file is correct, for example: DEVICE=eth0

On the Linux system to delete the network card of the specific solution is shared here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
