Hi All,
I'm new to Linux server concept. Can anybody tell me how to create subdomain in linux. Already I have domain "x" in my server, I want to create subdomain for domain "x". How can I do it without using CPanel

Thanks,

The software that handles DNS domains and subdomains is called BIND. There will be a configuration file on your server called named.conf and a directory that holds BIND's files (/etc/namedb/ perhaps?). Here's an example with a domain acme.com and a subdomain of sub.acme.com In named.conf you'll put an entry that looks like this:

Code:

zone "sub.acme.com" {
        type master;
        file "sub.acme.com.dns";
};

Then you'll create a file called sub.acme.com.dns that has the same format as the file for acme.com. Here's a sample file:

Code:

$TTL    3600
@               IN      SOA     acme.com. username.acme.com.  (
                                2010101401      ; Serial
                                3600            ; Refresh
                                300             ; Retry
                                3600000         ; Expire
                                3600 )          ; Minimum
                IN      NS      server.acme.com

@               IN      A       1.2.3.4

www             IN      A       5.6.7.8

If you have more questions please mention DNS or BIND so that people know what you're asking about.
