Primary DNS Server Configuration Part-2

Step-3: After complete the NIC configure you have to change the host name by following this command:

[root@ns1 ~]# vi /etc/sysconfig/network

(Original File):

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME=localhost.localdomain

(Modified File):

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME=ns1

Step-4: Now Edit hosts file for host name resolution by following this command:

[root@ns1 ~]# vi /etc/hosts

(Original File):

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1       localhost.localdomain localhost

(Modified File):

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1       localhost.localdomain localhost

210.207.201.1   ns1.alphabd.net      ns1

Step-5: Copy & Rename the named.rfc1912.zones file to named.conf file & Change the ownership & permission by following this command:

[root@ns1 ~]# cd /var/named/chroot/etc/

[root@ns1 etc]# cp named.rfc1912.zones  named.conf

[root@ns1 etc]# chown root:named named.conf

[root@ns1 etc]# chmod 777 named.conf

Now Create A Link into /etc directory of named.conf then edit.

[root@ns1 etc]# ln –s /var/named/chroot/etc/named.conf  /etc/named.conf

[root@ns1 ~]# vi /etc/named.conf
