ConfiguringTheDNSServerSetting Up a DNS Server if you are using redhat servers STEP 1...First we need to get the following bind packages.. # rpm -qa|grep bind bind-devel-9.2.1-16 bind-utils-9.2.1-16 bind-9.2.1-16 redhat-config-bind-1.9.0-13 STEP 2... After the above packages are installed we need to open/edit the file /etc/named.conf and then create a entry for our primary and secondary name servers,which are ns0.armia8dns.com and ns1.armia8dns.com and ns0.armia8dns.com has an ip 192.168.0.8 and ns2.armia8dns.com has the ip address 192.168.0.9
ADDING THE NAME SERVERS ns0.armiadns.com and ns1.armiadns.com... [~]# vi /etc/named.conf
zone "ns0.armia8dns.com" {
type master;
file "/var/named/ns0.armia8dns.com.db";
};
The 3rd step is to create the db file for the above dns in /var/named/ [~]# vi /var/named/ns0.armia8dns.com.db
$ORIGIN .
$TTL 86400
ns0.armia8dns.com IN SOA ns0.armia8dns.com. root.armia8.com. (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS ns0.armia8dns.com.
IN NS ns1.armia8dns.com.
IN A 192.168.0.8
IN MX 0 ns0.armia8.com.
$ORIGIN ns0.armia8dns.com.
localhost A 127.0.0.1
STEP 3 A Now again for ns1.armia8dns.com add the entry in /etc/named.conf as shown below zone "ns1.armia8dns.com" {
type master;
file "/var/named/ns1.armia8dns.com.db";
};
STEP 3 B Again create a file named /var/named/ns1.armia8dns.com.db
[~]# vi /var/named/ns1.armia8dns.com.db
$ORIGIN .
$TTL 86400
ns1.armia8dns.com IN SOA ns0.armia8dns.com. root.armia8.com. (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS ns0.armia8dns.com.
IN NS ns1.armia8dns.com.
IN A 192.168.0.9
IN MX 0 ns1.armia8.com.
$ORIGIN ns1.armia8dns.com.
localhost A 127.0.0.1
STEP 4... Now we can start named on the server and see if armia8dns worksfine or not, we can use the dig command or the command such as ping to test this. #dig ns0.armia8dns.com and dig ns1.armia8dns.com ADDING A DOMAIN TO THE DNS FILE AND TO /var/named STEP 5... The 4th step is to add a new domain "itmission.org" to the dns. STEP 6... Open the file /etc/named.conf and add the following line to the file named.conf [~]# vi /etc/named.conf
zone "itmission.org" {
type master;
file "/var/named/itmission.org";
};
STEP 7... The 7th step is to create the db file for the above domain "ITMISSION.ORG" dns in /var/named/ [~]# vi /var/named/itmission.org.db
$TTL 86400
@ IN SOA ns0.armia8dns.com. root.armia8.com. (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
itmission.org. IN NS ns0.armia8dns.com.
itmission.org. IN NS ns1.armia8dns.com.
itmission.org. IN A 192.168.0.8
localhost.itmission.org. IN A 127.0.0.1
itmission.org. IN MX 0 itmission.org.
www IN CNAME itmission.org.
mail IN CNAME itmission.org.
STEP 8... Restart the dns server and then try to check the domain itmission.org STARTING BIND SERVER /etc/init.d/named restart service named restart rndc reload STEP 9... Now if you would like to add subdomain entries...do use the following entries in the file /etc/named/itmission.org.db admin IN A 192.168.0.8 www.admin IN A 192.168.0.8 ads IN A 192.168.0.8 www.ads IN A 192.168.0.8 check to see if /etc/resolv.conf are setup correctly for DNS .
