CentOS 7 Plesk server DNS not starting

On a CentOS 7 Plesk server DNS failed to start. Plesk on CentOS 7 use named-chroot.service for starting DNS.

I tried to start DNS with

systemctl restart named-chroot

1	systemctl restart named-chroot

On checking status, it shows DNS failed to start

systemctl status named-chroot

1	systemctl status named-chroot

I removed Bind DNS server using command

plesk installer

1	plesk installer

Removed all bind related packages with yum. Removed all DNS configs from /etc and /var/named folder.

Reinstalled Bind DNS and run plesk repair to fix DNS entry

plesk repair dns

1	plesk repair dns

But it did not resolve the problem. I checked named.conf with

named-checkconf /etc/named.conf

1	named-checkconf /etc/named.conf

It showned error is related with

acl common-allow-transfer {
        11.11.12.100/255.255.255.0;
        1637:4100:203:6664::/64;
};

acl common-allow-transfer {

11.11.12.100/255.255.255.0;

1637:4100:203:6664::/64;

};

Problem is fixed by removing the entry “11.11.12.100/255.255.255.0” from

Plesk > Tools & Settings > DNS Zone Template > Transfer Restrictions Template

1	Plesk > Tools & Settings > DNS Zone Template > Transfer Restrictions Template

You can use IP or CIDR here. But you don’t need this if you don’t have secondary DNS servers.
