Centos system does not display network card information

Problem:

After installing CentOS 6.4 on the virtual machine, ifconfig only displays the information of the lo interface and does not display the information of the eth0 network card. Enter the /etc/sysconfig/network-scripts/ directory and you can see the ifcfg-eth0 file.

Solution:

1. Open the ifcfg-eth0 configuration file
