so pls guide me how to installation of ?dns and how to configure ?
There are two ways available for dns, one with the actual dns setup, and
other dns-kind of simple way with manual entries in resolv.conf.
http://www.cyberciti.biz/tips/linux-how-to-setup-as-dns-client.html
The way I understood the OP, he wants to setup DNS zone and not just
be a consumer from some other server that gets referenced via
/etc/resolv.conf
The quick (and archaic) way would be to add entries in /etc/hosts.
This works great when you have only one machine in your setup - no
overhead of installing BIND, creating forward and reverse maps etc.
See "man 5 hosts" for the format of each entry and also make sure that
/etc/nsswitch.conf has an entry like:
"hosts: files mdns4_minimal [NOTFOUND=return] dns"
"files" must be the first entry; it forces the name resolver to look
at /etc/hosts first before querying a DNS server.
and how to create domain and sub - domain ?
how to use that ?
This you can do by configuring / adding Virtual Hosts entries in the ?web
server config.
IMO, this is an incorrect answer. To be able to do the above you
still need the Vhosts to be defined in a DNS table (or /etc/hosts if
*all* name resolutions are done on one and only one machine).
To set up a "zone" associated with a domain name, OP needs to
register a domain name with a registrar and use that domain name.
Zones for sub-domains can be created by prefixing a name to the
registered domain name. I have seen people use domain names
registered for other entities internally - that creates problems and
should be avoided.
So for instance, let's say the domain name is registered as
example.com. A sub domains can be intra.example.com, further sub
domains could be chennai.intra.example.com etc. I hope you get the
picture.
BIND has excellent docs that come bundled with the software. I
suggest to OP to read those first and then ask specific queries on
things that you do not understand.
