The network card configuration file cannot be found under centos

Problem:

After installing CentOS6.5 using the VMware Workstation virtual machine, the IP of the computer always changes. The methods found online are all about changing the configuration file of the computer's network card, but the network card has an IP. After searching, it was found that there is no configuration file for the corresponding network card, so the following method is suitable for situations where the configuration file for the corresponding network card cannot be found.

Solution:

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

nmcli con

(recommended Tutorial: centos tutorial)

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.

service network restart

6. Check the IP again, it’s already fine and it won’t change in the future

ifconfig
