1.Required RPM

#bind-libs-9.3.3-10.el5

#bind-chroot-9.3.3-10.el5

#bind-devel-9.3.3-10.el5
#bind-utils-9.3.3-10.el5

#bind-libbind-devel-9.3.3-10.el5

#bind-9.3.3-10.el5

#bind-sdb-9.3.3-10.el5

#caching-nameserver-9.3.3-10.el5

2.Some file check

# vim /etc/hosts

# vim /etc/sysconfig/network

# vim /etc/resolv.conf

3.Configure

# cp -p /etc/named/caching-nameserver.conf /var/named/chroot/etc/named.conf

4.Soft link

# ln -s /var/named/chroot/etc/named.conf /etc/named.conf

5.Check Permission

# ll -ld /etc/named.conf

root named named.conf

6.Create named.conf

#vim /etc/named.conf

listen-on Port 53 { 127.0.0.1; Server IP; } ;

allow-query { localhost; any; } ;

allow-query-cache { localhost; any; } ;

match-clients { localhost; any; } ;

match-destinations { localhost; any; } ;

recursion yes;

zone “example.com” {

type master;

file “example.com.zone”;

};

zone “0.168.192.in-addr.arpa” {

type master;

file “rev-example.com.zone”;

};

7.Test named.conf

# named-checkconf

cd /var/named/chroot/var/named/

# cp -p localdomain.zone example.com.zone

# vim example.com.zone

$TTL 86400

@ SOA example.com. root (

42 ; serial (d. adams)

3H ; refresh

15M ; retry

1W ; expiry

1D ) ; minimum

IN NS shashi.example.com.

shashi IN A 192.168.0.254

client IN A 192.168.0.2

# cd /var/named/chroot/var/named/

# cp -p named.local rev-example.com.zone

# vim rev-example.com.zone

$TTL 86400

@ IN SOA example.com. root.shashi.example.com. (

42 ; serial (d. adams)

3H ; refresh

15M ; retry

1W ; expiry

1D ) ; minimum

IN NS shashi.example.com

254 IN PTR shashi.

2 IN PTR client.
