Note: Before Start
Set ip-address manually (I use 192.168.72.140)
Set hostname FQDN (I use server1.domain.com)

Step: 1. To set IP-Address :

# system-config-network-tui

Uncheck DHCP & Give the IP Address manually.

OK -> Quit

Step: 2. Installation of DNS Server :

# yum -y install bind* caching-nameserver

Step: 3. Make sure that the Host Names are set Properly :

# vi /etc/hosts

127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.72.140 server1.domain.com server1 (IP Address & FQDN)

-- Save & Quit (:wq)

# vi /etc/sysconfig/network

NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=server1.domain.com

-- Save & Quit (:wq)

Step: 4. Set Hostname :

# hostname server1.domain.com

Step: 5. DNS resolve Entry :

# vi /etc/resolv.conf

search domain.com
nameserver 192.168.10.1

-- Save & Quit (:wq)

Step: 6. Configure DNS Server :

# vi /etc/named.conf

Edit those Lines :

options {
        listen-on port 53 { 192.168.72.140; };
#       listen-on-v6 port 53 { ::1; };
allow-query { any; };

Add Those Lines :

zone"domain.com" IN {
type master;
file "forward.zone";
allow-update { none; };
};

zone"72.168.192.in-addr.arpa" IN {
type master;
file "reverse.zone";
allow-update { none; };
};

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

-- Save & Quit (:wq) 

Note: Create forward and reverse zone files which we mentioned in the ‘/etc/named.conf’ file.

Step: 7. Create Forward Zone :

# vi /var/named/forward.zone

$TTL 86400
@   IN  SOA     server1.domain.com. root.server1.domain.com. (
        2011071001  ;Serial
        3600        ;Refresh
        1800        ;Retry
        604800      ;Expire
        86400       ;Minimum TTL
)
           IN   NS          server1.domain.com.
server1    IN   A           192.168.72.140

-- Save & Quit (:wq) 

Step: 8. Create Reverse Zone :

# vi /var/named/reverse.zone

$TTL 86400
@   IN  SOA     server1.domain.com. root.server1.domain.com. (
        2011071001  ;Serial
        3600        ;Refresh
        1800        ;Retry
        604800      ;Expire
        86400       ;Minimum TTL
)
          IN  NS           server1.domain.com.
140       IN  PTR          server1.domain.com.

-- Save & Quit (:wq) 

Step: 9. Now Change Group of forward.zone & reverse.zone :

# cd /var/named/
# chgrp named forward.zone
# chgrp named reverse.zone

Step: 10. Restart the named Service :

Note: FIXING THE BIND (NAMED) SERVICE BUG – GENERATING /ETC/RNDC.KEY

# rndc-confgen -a -r /dev/urandom

# service named restart
# chkconfig named on

Step: 11. The DNS Server is ready now, 9. it’s time to Test :

# dig server1.domain.com
# dig -x 192.168.72.140
# nslookup
> sever1.domain.com
> 192.168.72.140
