CentOS 7 no interface, no internet! installed on VMware workstation.

Job for network.service failed because the control process exited with error code.

This is what CentOS 7 says while you are trying to restart network.servce. New bees always runs into this problem i think atleast once. Because it was me too. So here i’m writing an easy solution.

When you ran into this problem your “ifconfig” command will only show you “l0” and/or “virbr0” in the list. There is no “eth0” or “eno16777736” device there. Then it must be giving big pain to your head.

Use below command …

dhclient -v

It will bound some IP address to the interface, its taking IP from DHCP, output will look something similar like below…

[root@localhost Desktop]# dhclient -v

And Boom!!! your VM machine will have internet again… you can create a file with this command and make it auto start in boot. then you dont have to do this again and again…

Thanks!!!
