You can stop NetworkManager from managing the resolv.conf file, which makes sure that the DNS servers provided by DHCP are ignored. In CentOS or Red Hat Enterprise Linux (RHEL) 7, you can find your /etc/resolv.conf file, which holds all nameserver configurations for your server, to be overwritten by the NetworkManager.

I deleted both the resolvconf folder and the resolv.conf file in /etc by mistake, assuming that resolvconf was causing UCK to fail. Now the application has upgraded, fixing the issue, but it says no file named resolv.conf in /etc. What it says is correct because I deleted those files.

The /etc/resolv.conf file will be overwritten if any network interfaces use DHCP for activation. To prevent this, ensure such interfaces have PEERDNS=no set in their ifcfg file, for example: # cat /etc/sysconfig/network-scripts/ifcfg-eth0 TYPE=Ethernet DEVICE=eth0 BOOTPROTO=dhcp PEERDNS=no

That made it incredibly simple to manage what DNS servers would be used by the machine. The script reads the nameservers and the search domains that it finds in /etc/resolv.conf, creates the config files in /etc/dnsmasq.d based on them and then rewrites a new /etc/resolv.conf with a new configuration. The problem I have is that at a service restart for NetworkManager, the script seems to run on predefined version of /etc/resolv.conf.
