Apache2 vhost configuration problem

Question

What I'd like apache to do is match every request for example.com and redirect to www.example.com. Any other hosts sent by a browser that are not on this domain should return a 404.

Here are my two vhosts:

example.com:

<VirtualHost *>
    ServerAdmin [email protected]
    ServerName www.example.com
    ServerAlias *.example.com

    DocumentRoot /var/www/example.com/

    <Directory />
            Options FollowSymLinks
            AllowOverride All
    </Directory>

    RewriteEngine on
    RewriteCond %{HTTP_HOST} ^.*example\.com$ [NC]
    RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
    RewriteRule ^(.*)$ http://www.example.com$1 [R=301,L]

    ErrorLog /var/log/apache2/error.log
    LogLevel warn
    CustomLog /var/log/apache2/access.log combined
</VirtualHost>

000-default:

<VirtualHost *>
    Redirect 404 /
</VirtualHost>

What actually happens is that "www.example.com" is beeing served as it should, a host header of "test" is beeing 404'd as it should, while "example.com" is beeing 404'd, and it shouldn't.

It's like apache matches "www" to the ServerName directive, but the ServerAlias is beeing ignored, and a subdomain of "sub" matches the default vhost instead.

Answer 1

<VirtualHost *>
   ServerName example.com
   Redirect permanent / http://www.example.com/
</VirtualHost>

Will handle fixing your www/non-www stuff.

Then for any other hosts, just point your default vhost to some empty documentroot (or some script that handles whatever custom 404 you want.

Answer 2

You need to add example.com to your ServerAlias line:

ServerAlias example.com *.example.com

And then rewrite your RewriteCond to be:

RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com$1 [R=301,L]

...because I don't think you need that first %{HTTP_HOST} line.

Answer 3

using

ServerName example.com
ServerAlias *.example.com

I get the redirect from non-www to www, but example.com alone returns a 404
