[Charlug] subdomain help/explanation

[Lawrence Teo]

You can do this with the VirtualHost directive in Apache, something
like this:

<VirtualHost *>
    ServerName domain.com
    DocumentRoot /var/www/com/domain
    ServerAdmin webmaster at domain.com
    ErrorLog logs/domain.com-error_log
    CustomLog logs/domain.com-access_log combined
</VirtualHost>

<VirtualHost *>
    ServerName sub.domain.com
    DocumentRoot /var/www/com/domain/sub
    ServerAdmin webmaster at domain.com
    ErrorLog logs/sub.domain.com-error_log
    CustomLog logs/sub.domain.com-access_log combined
</VirtualHost>

Then you'll need to tell GoDaddy to point both domain.com and
sub.domain.com to the IP address of your webserver. Apache will
then decide which directory to serve depending on whether the
browser is asking for domain.com or sub.domain.com.

There are more steps to setting up virtual hosts but hopefully
the above will help get you started. Please backup your Apache
conf file first and document everything you do. :-)

PS: If you use /var/www/com/domain as the DocumentRoot for
domain.com and /var/www/com/domain/sub as your DocumentRoot
for sub.domain.com, that means that someone can access the files
for sub.domain.com by using http://domain.com/sub -- that may
or may not be what you want.

PS(2): The steps mentioned are for Apache on OpenBSD but it should
be generally applicable to Apache on Linux.

Hope it helps,
Lawrence
