logging {
channel b_query {
file "/var/log/bind9/query.log" versions 2 size 1m;
print-time yes;
severity info;
category queries { b_query; };

Now create the log directory for Bind9.

mkdir /var/log/bind9
chown bind:bind /var/log/bind9

Edit /etc/bind/named.conf to configure your domain zone file location. Append the following lines:

zone "" {
type master;
file "/etc/bind/zones/";
