[gentoo-server] apache config question

[gentoo-server] apache config question

[Ben Munat]

Hello. Does anyone know how I can configure apache 2.0.x to map all 
requests to a given subdomain to a give directory regardless of the rest 
of the server name?

Doing this for my webmail setup... so mail.foo.com, mail.bar.com, 
mail.baz.com, etc. should all map to my squirrelmail directory.

I've been doing this by adding virtual host directives for the mail 
subdomain for every domain I add but it seems like there should be an 
easier way. I figure I can probably do it with mod_rewrite but I'm no 
wizard with that.

thanks,

b

<VirtualHost *:80>
        ServerName domain.com
	ServerAlias www.domain.com
	ServerAlias webmail.domain.com
	ServerAlias ...
        ServerAdmin ...
        DocumentRoot "..."
	...
</VirtualHost>

The same applies for SSL ports.

No mod_rewrite needed for that.

Guess he meant that this should happen automatically and he does'nt want to 
add the subdomain to every domain... Would be nice to know for me, too.

Ahhh, ok, sorry, I misunderstood your question.

Maybe searching for the equivalent in apache for that lighttpd evhost
will work:

$HTTP["host"] =~ "^(mail.)?([^.]+)\.([a-z]{2,3})\.([a-z]{2,3})$" {
  evhost.path-pattern = "/path/to/squirrel/"
  ...rewrites...here...
}

Right... plus I don't think the example given would even work if the 
ServerAliases listed need to go to different directories. I don't think 
there's any way to do this without mod_rewrite... hoping someone can 
just slip me the correct rule.

Yeah... something like that. Time to get out the old regex assistant. 
The hardest part of rewrite for me is it's always hunt and peck in the 
dark.... I've never figured out how to get apache to log it's attempts 
at matching.

IIRC Apache has a directive called RewriteLog and another one called
RewriteLogLevel that will help you arrive to good port.

dev-util/txt2regex can help you write the right rules.

If one finds the solution for this - would be nice if he could write it to the 
ML. Thanks,

You can use "mod_vhost_alias"

In your httpd.conf :

    LoadModule vhost_alias_module            modules/mod_vhost_alias.so

The virtual host declaration :

<VirtualHost _default_:80>
    VirtualDocumentRoot "/var/www/%1"
</VirtualHost>

Then, you just have to put your web pages under /var/www/mail.

It should work. If it doesn't work, let me know. More information are at : 
http://httpd.apache.org/docs/2.0/mod/mod_vhost_alias.html

If I understand you right, you want mail.* to point to say /var/www/mail
, while letting other domains/subdomains point to their own places.

Here's how I handle it on my server:

<VirtualHost *:80>
    ServerName mail.your-domain.com
    ServerAlias mail.*
    DocumentRoot /var/www/mail
    [... other configuration as needed ...]
</VirtualHost>

This needs to be one of the first virtual hosts that apache reads so
that it matches mail.* before it matches say *.blahblah.com (if you are
hosting blahblah.com)

Hah... didn't think you could put a * in the ServerAlias... haven't 
found any documentation to that effect. But I'll try this.

And Nicholas, I haven't had a chance to try your solution yet, but I 
appreciate it. Thanks to everyone who tried to help. I can probably get 
one of these to work.

That's because there is (well, _I_ find it far easier, at least ;)
