Unable to start named/bind DNS in Plesk: unknown option ‘version’

Symptoms

• It is not possible to start bind/named service, the following error is shown:

  # systemctl status named-chroot
  Mar 21 05:48:19 named-checkconf: /etc/named-user-options.conf:1: unknown option 'version'
  Mar 21 05:48:19 named-checkconf: /etc/named-user-options.conf:2: unknown option 'auth-nxdomain'
  Mar 21 05:48:19 systemd: named-chroot.service: control process exited, code=exited status=1

Cause

Custom directive include "/etc/named-user-options.conf" specified in /etc/named.conf

Resolution

1. Login to the server via SSH.
2. Check that include "/etc/named-user-options.conf" is included only in the top of /etc/named.conf, This directive must exist only once within the file:

   options {
   include "/etc/named-user-options.conf";
   allow-recursion {
   localnets;
   };

3. Remove any extra include "/etc/named-user-options.conf" directives, save and close the file.
4. Restart the bind/named service:

# systemctl restart named-chroot
