CentOS 7: Could not retrieve mirrorlist

Fix of the yum update error: could not retrieve mirrorlist.

The cause of the problem is that dhclient didn't start at the boot, so you don't have network.
To fix that, you need to edit /etc/sysconfig/network-scripts/ifcfg-ens33 (in my case). Can be also eth0.
Change ONBOOT=no to ONBOOT=yes. That will make dhclient start on boot.
Then run dhclient, so you have network in current session.

Hello from Brasil !!!

[TheBleyach]

First of all, you're amazing and this is a terrific fix to my problem. Thank you!!! However, I'm not quite certain as to how this remedied my situation. You see, I'm running CentOS 7 on a VM and the NAT adapter had an IP of 10.something (private range ofc). When I ran "sudo ifup enp0s3", I was able to access the internet. But only when I further ran "dhclient" was I able to retrieve the mirror list. What do you think changed here?

This was perfect. Thank you for such a thorough and concise video!

Hi, but in my CentOS7, there is no such a file "ifcfg-ens33" in folder. Instead, there is a "ifcfg-lo" file, is this the right one?

[pranayadahal]

You just made my day. I love you mate.

[Pyxelles]

Thanks but when I vimed into the my ONBOOT was already = yes hence didn't change anything and still have the same problem.

[nicoleyizhenke]

Thank you very much! Easy to follow, and work perfectly fine.

[superlogicalman]

Thanks so much I wanted to test something on centos for work and ran into this issue.

I have another problem. you could have fixed your problem typing dhclient. If would have sufficed but editing the file to make it persistent is of course more convenient.
