What should I do if the centos system cannot find the network card configuration file?

Problem:

CentOS cannot find the network card configuration file after adding a new network card.

After installing CentOS6.5 using the VMware Workstation virtual machine, the IP of the computer will always change.

Solution:

1. Use the nmcli con command to check the UUID information of the network card and write down the UUID value

2. Use the ip addr command to view the network card information and remember the MAC address of eth5

ip addr

3. Copy the ifcfg-eth0 file in the /etc/sysconfig/network-scripts/ directory and name it ifcfg-eth5.

cd /etc/sysconfig/network-scripts/
cp ifcfg-eth0 ifcfg-eth5

4. Re-modify the configuration file, pay attention to modify the necessary hardware information.

vi ifcfg-eth5

5. Restart the network card.
