Hi everyone,

I would greatly appreciate it if someone could help point out what I might have done wrong in trying to map a folder on our server i.e mywebsite.com/abc to a similarly named subdomain i.e abc.mywebsite.com.

Here's what our Linode DNS entries look like:
-------------------------------------------------------

DNS Manager » abc.mywebsite.coom

SOA Record
Primary DNS Email Default TTL Refresh Rate Retry Rate Expire Time Options
ns1.linode.com me@myemail.com Default Default Default Default Settings

NS Records
Name Server Subdomain TTL Options
ns1.linode.com abc.mywebsite.com Default Edit | Remove
ns2.linode.com abc.mywebsite.com Default Edit | Remove
ns3.linode.com abc.mywebsite.com Default Edit | Remove
ns4.linode.com abc.mywebsite.com Default Edit | Remove
ns5.linode.com abc.mywebsite.com Default Edit | Remove
Add a new NS record

MX Records
Mail Server Preference Subdomain TTL Options
mail.mywebsite.com 10 Default Edit | Remove
Add a new MX record

A/AAAA Records

www abc.mywebsite.com Default Edit | Remove
Add a new CNAME record

TXT Records
Name Value TTL Options
Add a new TXT record

SRV Records
Service Domain Priority Weight Port Target TTL Options
-----------------------------------------------------------------------------------------

..and here's what the virtual hosts section of Apache config file looks like:

<VirtualHost 12.34.56.78:80>
ServerAdmin webmaster@mywebsite.com
DocumentRoot /var/www/vhosts/mywebsite.com/httpdocs/
ServerName mywebsite.com
ServerAlias http://www.mywebsite.com

</Directory>

</VirtualHost>

<VirtualHost 12.34.56.78:443>

</Directory>

</VirtualHost>

<VirtualHost 12.34.56.78:443>
ServerAdmin webmaster@mywebsite.com
DocumentRoot /var/www/vhosts/mywebsite.com/httpdocs/
ServerName abc.mywebsite.com
ServerAlias abc.mywebsite.com
<Directory /var/www/vhosts/mywebsite.com/httpdocs/abc/>
AllowOverride all
</Directory>
Alias /webmail "/var/www/html/webmail/"
Alias /postfixadmin "/var/www/html/postfixadmin"
ErrorLog logs/mywebsite.com.com-error_log
CustomLog logs/mywebsite.com-access_log common

SSLCertificateKeyFile /etc/pki/tls/private/mywebsite.key
SSLCACertificateFile /etc/pki/tls/certs/ssl123.crt
</VirtualHost>

---------------------------------------------------------------------

I copied the 3rd section of the virtual host section of our Apache config from the second section and made modifications to it.

Thanks.

The site just started resolving...but abc.mywebsite.com its resolving to mywebsite.com.
I'm now thinking that there must be an issue with the Apache config file..
Can anyone help spot it?

Check your DocumentRoot for abc.

Hi Nibbler,

Thanks for your response.

I have changed document root to

/var/www/vhosts/mywebsite.com/httpdocs/abc 

and/or

/var/www/vhosts/mywebsite.com/httpdocs/abc/ 

and restarted the server a number of times.

abc.mywebsite.com still resolves to mywebsite.com.

Could there be other factors that could be responsible?
e.g my DNS entries for creating this subdomain. Here's what my DNS entries look like:

DNS Manager » abc.mywebsite.coom

SOA Record
Primary DNS   Email   Default TTL   Refresh Rate   Retry Rate   Expire Time   Options
ns1.linode.com   me@myemail.com    Default    Default    Default    Default   Settings

Add a new A record

CNAME Records

www   abc.mywebsite.com    Default   Edit | Remove
Add a new CNAME record

TXT Records
Name   Value   TTL   Options
Add a new TXT record

SRV Records
Service   Domain   Priority   Weight   Port   Target   TTL   Options

Are you able to spot anything I might have entered wrongly?
Thanks.

RH19,
I don't see a vhosts config for 12.34.56.78:80 for abc.mywebsite.com. Have you tried accessing it via https to see if the :443 config is working for abc.mywebsite.com ?

Maybe you could obscure the PUBLIC DNS settings and the PUBLIC IP numbers even more to make it even harder to guess what's going on with your PUBLIC website.
