[CentOS] How to configure DNS server in RHEL 7 / CentOS 7

How to configure DNS server and search domain common for all network interfaces not per device?

The only reliable way I found we can set DNS name server and search domain in CentOS 7 is using nmcli which adds DNS name server and search domain to *a specific interface*, e.g. nmcli con mod eth0 +ipv4.dns [IP_ADDRESS]. But I want to set them for all interfaces weather they are configure and connected or not. How can we do that?

More back ground information: I am using NetworkManager and nmcli tool to configure multiple wired Ethernet interfaces on CentOS 7. I want to set common DNS name server and search domain for all interfaces. /etc/resolv.conf is generated by NetworkManger and we cannot manually modify it.

Thanks, Joe
