DNS Server Installation Step by Step Using red hat enterprise linux 7

DNS server in RHLE 7

yum install bind*

vim /etc/named.conf

Change below lines:

Default line: listen-on port 53 { 127.0.0.1; };

Edited line: listen-on port 53 { 127.0.0.1; 192.168.20.230; }; [add you server IP]

Default line: allow-query     { localhost; };

Edited line: allow-query     { localhost; any; };

Default line: recursion yes;

Edited line: recursion no;

Copy below info format from (/etc/named.rfc1912.zones)

zone "localhost" IN {

        type master;

        file "named.localhost";

        allow-update { none; };

};

And edit like below.  vim /etc/named.conf

zone "xyz.com" IN {

        type master;

        file "xyz.fw.zone";

        allow-update { none; };

};

Go to cd /var/named/

Check list of files by using “ll” [Double L]

The result will be like this

drwxr-x--- 7 root  named   56 Nov 25 17:29 chroot

drwxrwx--- 2 named named   22 Nov 25 18:05 data

drwxrwx--- 2 named named   58 Nov 25 19:09 dynamic

-rw-r----- 1 root  named 2076 Jan 28  2013 named.ca

-rw-r----- 1 root  named  152 Dec 15  2009 named.empty

-rw-r----- 1 root  named  152 Jun 21  2007 named.localhost

-rw-r----- 1 root  named  168 Dec 15  2009 named.loopback

drwxrwx--- 2 named named    6 Jan 29  2014 slaves

Now we’ll copy the named.localhost file to the same name that we declare in name.conf file [file name was xyz.fw.zone]

cp named.localhost xyz.fw.zone

chown root:named xyz.fw.zone

vim xyz.fw.zone

We must edit this file like below

$TTL 60

@       IN SOA  reyaz.xyz.com. root. (

                                        01      ; serial

                                        1D      ; refresh

                                        1H      ; retry

                                        1W      ; expire

                                        3H )    ; minimum

@       IN      NS      reyaz.xyz.com.

@       IN      A       192.168.20.230

reyaz   IN      A       192.168.20.230

 

Our DNS configuration done successfully, now check whether it’s working or not.
