Hi Zhengyu Pan
Have you tried to put this nameserver address in dhclient.conf?
>From man dhclient.conf
append { [option declaration] [, ... option declaration] }
If for some set of options the client should first use the values
supplied by the server, if any, and then use values you supply,
these values can be defined in the append statement. The append
statement can only be used for options which allow more than one
value to be given. This restriction is not enforced - if you
ignore it, the behaviour will be unpredictable.
I haven’t use the ap- or prepend options, but the supersede option work like a
charm (at least on FreeBSD)

Subject: dhclient hook not overwritten /etc/resolv.conf
Hi,
My OS is Centos7. I add a bash script dns.sh in /etc/dhcp/dhclient-exit-hooks.d
. The script content is
#!/bin/bash
echo “nameserver 1.1.1.1” >> /etc/resolv.conf
I want to append a nameserver in /etc/resove.conf.
However, when I restart network. /etc/resove.conf not changed.
/etc/resove.conf.save append this line.
Why happens that? How can I append a nameserver in /etc/resove.conf?
Zhengyu
