Primary DNS Server 

Step- 1: Check bind and caching-nameserver rpm package is installed or not by following this command:

                       

[root@ns1 ~]# rpm -qa | grep –i bind*    or

[root@ns1 ~]#  rpm –qa bind*            (if installed then it will show all the bind related packages)

bind-chroot-9.3.6-4.P1.el5

bind-libs-9.3.6-4.P1.el5

ypbind-1.19-12.el5

bind-9.3.6-4.P1.el5

bind-utils-9.3.6-4.P1.el5

bind-sdb-9.3.6-4.P1.el5

bind-devel-9.3.6-4.P1.el5

bind-libbind-devel-9.3.6-4.P1.el5

system-config-bind-4.0.3-4.el5

[root@ns1 ~]# rpm -qa caching-nameserver* 

Caching-nameserver-9.3.6-4.P1.el5

            If not installed, then installed the packages using  Yum command:

[root@ns1 ~]# Yum Install bind* caching-nameserver*

Step-2: Check and Configure the Network Card:

[root@ns1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

(Original File):

#Broadcom Corporation Net link BCM57875 Gigabyte Ethernet PCI Express

DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:0C:29: EB: B2: CA
ONBOOT=yes

(Modified File):

#Broadcom Corporation Net link BCM57875 Gigabyte Ethernet PCI Express

DEVICE=eth0

BOOTPROTO=static

HWADDR=00:0C:29: EB: B2: CA

ONBOOT=yes

TYPE=Ethernet

PEERDNS=no

USERCTL=no

IPV6INIT=no

IPADDR=210.207.201.1

NETMASK=255.255.255.0

NETWORK=210.207.201.0

BROADCAST=210.207.201.255

After changing you have to reload/restart the NIC(eth0) card by following command:

[root@ns1 ~]# ifdown eth0

[root@ns1 ~]# ifup eth0

[root@ns1 ~]# service network restart

Next- Step-3:

After complete the NIC configure you have to change the host name by following this command
