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.
Since the entries end up in /etc/resolv.conf they are not per interface ...
You can always set PEERDNS=no and configure /etc/resolv.conf manually or with your CM tool of choice
