Why does creating Apache wildcard subdomain and IP create an infinite redirect?

  • 772

I have Apache configure with several IP addresses:

Listen 111.111.111.111:80
Listen 111.111.111.111:443

Listen 222.222.222.222:80
Listen 222.222.222.222:443

Listen 333.333.333.333:80
Listen 333.333.333.333:443

(IPs are fake)

I have several VirtualHosts, one of which is a wildcard subdomain.

<VirtualHost *:80>
        ServerName *.example1.com
        DocumentRoot /var/www/vhosts/example1-wc/docs
</VirtualHost>

<VirtualHost *:80>
        ServerName www.example1.com
        DocumentRoot /var/www/vhosts/example1/docs
</VirtualHost>

<VirtualHost *:80>
        ServerName www.example2.com
        DocumentRoot /var/www/vhosts/example2/docs
</VirtualHost>

This works fine. Requests to www.example1.com are served under the example1 docroot, requests for example.example1.com are served under the example1-wc docroot and www.example2.com for example2 docroot.

I can change www.example2.com to use a specific IP without any problems however if I change the wildcard vhost *.example1.com to a specific IP:

<VirtualHost 111.111.111.111:80>
        ServerName *.example1.com
        DocumentRoot /var/www/vhosts/example1-wc/docs
</VirtualHost>

Then requests to www.example1.com create an infinite redirect loop on itself. This happens regardless of whether I use:

<VirtualHost 222.222.222.222:80>
        ServerName www.example1.com
        DocumentRoot /var/www/vhosts/example1/docs
</VirtualHost>

or

<VirtualHost *:80>
        ServerName www.example1.com
        DocumentRoot /var/www/vhosts/example1/docs
</VirtualHost>

Why is this happening and how can I get each virtualhost on its own IP?

    I'm not sure if this is the root of your problem, but you should probably have the directives

    NameVirtualHost 111.111.111.111:80
NameVirtualHost 222.222.222.222:80
NameVirtualHost 333.333.333.333:80

    So the full configuration would have these directives in it:

    Listen 111.111.111.111:80
NameVirtualHost 111.111.111.111:80
<VirtualHost 111.111.111.111:80>
    ServerName *.example1.com
    DocumentRoot /var/www/vhosts/example1-wc/docs
</VirtualHost>

Listen 222.222.222.222:80
NameVirtualHost 222.222.222.222:80
<VirtualHost 222.222.222.222:80>
    ServerName www.example1.com
    DocumentRoot /var/www/vhosts/example1/docs
</VirtualHost>

Listen 333.333.333.333:80
NameVirtualHost 333.333.333.333:80
<VirtualHost 333.333.333.333:80>
    ServerName www.example2.com
    DocumentRoot /var/www/vhosts/example2/docs
</VirtualHost>

    but this should not appear anywhere:

    NameVirtualHost *:80

    Here's some further reading, if you're interested: http://httpd.apache.org/docs/2.2/vhosts/details.html (good luck making sense of it ;-)

  2. Just a wild guess, but have you tried putting the definition for the wildcard subdomain after the www.example1.com definition?
