After installing BIND with your package manager (yum) you need to edit the main configuration file. The following configuration was adopted to my needs but you should get the points. For more infos about the config switches you can look at the named manual pages.

edit /etc/named.conf and change following lines:

options {
    listen-on-v6 { none; };
    listen-on port 53 { 127.0.0.1; YOUR_LOCAL_IP; };
    allow-query { localhost; };
    allow-transfer { none; };
    recursion no;
}

add your zone information to the file:

zone "MYDOMAIN" {
    type master;
    file "MYDOMAIN.zone";
    allow-query { any; };
}

now create your zone file /var/named/MYDOMAIN.zone and add following lines:

$TTL 3h
@             IN SOA          ns.MYDOMAIN. root.MYDOMAIN. (
                                     MODIFICATION ; serial
                                     3h ; refresh
                                     1h ; retry
                                     1w ; expiry
                                     1d  ; minimum
)
MYDOMAIN.             IN MX          0 mail.MYDOMAIN.
MYDOMAIN.             IN TXT         "v=spf1 ip4:YOUR_PUBLIC_IP/32 mx ptr mx:mail.MYDOMAIN -all"
MYDOMAIN.             IN NS           ns.MYDOMAIN.
MYDOMAIN.             IN NS           SLAVE_DNS_SERVER
www.MYDOMAIN.      IN A             MYHOST_IP
ns.MYDOMAIN.         IN A             MYHOST_IP
mail.MYDOMAIN.       IN A             MYHOST_IP
HOST.MYDOMAIN.    IN A             MYHOST_IP

now, save the file and make sure it has the right permissions:

# chown root:named /var/name/MYDOMAIN.zone
# chmod 640 /var/name/MYDOMAIN.zone

then add a firewall rule if not alreaqdy done:

# iptables -A INPUT -m state –state NEW -p udp –dport 53 -j ACCEPT

and (re-)start the nameserver.
