DNS server won't stay!

So I have been getting this error

I did some research on the web and found it is an issue with the DNS so the information I found on ask Ubuntu said to do this

sudo nano /etc/resolv.conf or nano /etc/resolv.conf

and then I did this

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 8.8.8.8 nameserver 8.8.4.4

Now I see the comment that my changes will be overwritten, it works until I reboot and then they are blank. How do I permanently set these as my DNS servers?

I am running Ubuntu 14.04.2 server 64 Bit.

Thanks.

Hi grier-devon.

Is the server set with a static IP? If so, you need to add a line like this to your /etc/network/interfaces.

dns-nameservers 8.8.8.8  8.8.8.4

And also set /etc/resolv.conf as symbolic link. Here is a similar thread with more details.

If the server is getting its IP from a DHCP server, then the server is the one to be set to handle the DNS addresses.

Hope it helps. Let us know if that helps, and you if you have more questions.
Regards.

You can also do this, I believe, by clicking on the network icon in your panel and choosing Edit.
Go to the IPv4 tab and add the DNS servers you want as additional, similar to the way I show in the screenshot, or even change the

Automatic (DHCP)

to

Automatic (DHCP) addresses only

and again add those DNS servers you want in the DNS Servers box.

That should then stick as you want it to.

Thanks papibe,
Adding "dns-nameservers 8.8.8.8 8.8.8.4" to the "/etc/network/interfaces" fixed the problem as I am running the server static. Weird how it took a week after the server setup for this to happen, I appreciate your help!
