Disable systemd-resolved on Ubuntu/Deb/CentOS
systemd-resolved provide DNS resolver facility in newer version of Linux servers running systemd.
I prefer manually editing /etc/resolv.conf and add resolvers. If you are running your own DNS server, then you need to disable systemd-resolved as it listen on port 53, with out disabling the service, you can’t start your DNS server.
To disable systemd-resolved, run
|
1 2 |
wget https://raw.githubusercontent.com/serverok/server-setup/master/tools/disable-systemd-resolved.sh bash disable-systemd-resolved.sh |
Or do the following.
|
1 2 |
systemctl disable systemd-resolved.service systemctl stop systemd-resolved |
Now create /etc/resolv.conf file
|
1 2 3 4 5 |
rm -f /etc/resolv.conf tee /etc/resolv.conf << END nameserver 8.8.8.8 nameserver 1.1.1.1 END |
See resolv.conf, dns
