Solution: after centos6 is installed, there is no eth0 and only the loopback address

After centos6 is installed, run the ifconfig command without the eth0 address. only the lo loopback address is used to check the eth0 address. it is obvious that the preceding no address must be changed to yes, and then save and exit. Restart the network: servicenetworkrestart is effective now with the ifconfig command. I use commands to obtain ip addresses here. In fact, there is no need to be so troublesome. you can use ifconfig. here I will contact you for the value. of course, there are many value methods, as long as the task can be completed.

After centos6 is installed, the ifconfig command does not have the eth0 address and only the lo loopback address.
