On Ubuntu I use the resolvconf utility to update & maintain /etc/resolv.conf
On CentOS 7, the resolvconf utility doesn't appear to exist.
What is the correct way to maintain /etc/resolv.conf file on CentOS 7 ?
KR, Nath

The correct way depends of your environment. I have an environment where all servers receive DNS settings through DHCP.– ZinaCommented Nov 13, 2016 at 14:38

You may try to use openresolv (roy.marples.name/projects/openresolv/index) compiling it yourself.– NuTTyXCommented Nov 13, 2016 at 14:43

Thanks for the responses, they all helped me find the solution. Thanks Hannu - using nmcli con edit , then set ipv4.dns allowed me use NetworkManager to update resolv.conf. Zina - I was receiving a default nameserver from my DHCP client and NetworkManager automatically adds it to the top. Cheers guys!
