How to configure DNS in RHEL 5

1) yum install -y bind* caching-nameserver

2) check the ip address

3) cd /var/named/chroot/etc

    ls ---> localtime named.caching-nameserver.conf named.rfc1912.zones rndc.key

4) cp named.caching-nameserver.conf named.conf

5) vim named.conf

   listen-on port 53 (192.168.1.11;};
 
  # not required listen-on-v6 port 53 comment it

   allow-query { any; };

match-clients { any; };
match-destinations { 192.168.1.11; };

6) vim named.rfc1912.zones

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

zone "1.168.192.in-addr.orpa" IN {
type master;
file "reverse.zone";
allow-update { none; };
};

7) chgrp named named.conf

8) cd /var/named/chroot/var/named

    ls---> data localhost.zone named.ca named.local slaves
localdomain.zone named.broadcast named.ip6.local named.zero

9) cp localdomain.zone forward.zone

10) cp named.local reverse.zone

11) vim forward.zone

@ IN SOA server.mydomain.com. root.server.mydomain.com. {

IN NS  server.mydomain.com.
server IN A 192.168.1.11

12) vim reverse.zone
@ IN  SOA  server.mydomain.com. root.server.mydomain.com. {

IN NS server.mydomain.com.
111 IN PTR server.mydomain.com.

13) chgrp named forward.zone
    chgrp named reverse.zone

14) vim /etc/hosts

192.168.1.111  server.mydomain.com server
15) vim /etc/resolv.conf

search mydomain.com
nameserver 192.168.1.11

16) check full hostname is there in /etc/sysconfig/network

17) service named restart

18) dig server.mydomain.com  ----> for forward zone

19) dig -x 192.168.1.11  ---> for reverse lookup zone

20) nslookup
>server.mydomain.com

>192.168.1.11
