Apache2 VirtualDocumentRoot and Proxy

  • 772

I use a very simple /etc/apache2/sites-enabled/000-default configuration like

<VirtualHost 117.121.241.184>
UseCanonicalName    Off
VirtualDocumentRoot /srv/www/%0
Options All ExecCGI
LogFormat "%V %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" vhost_common
CustomLog /var/log/apache2/access.log vhost_common
</VirtualHost>

Where 117.121.241.184 is the IP of my machine I'm setting upon.

Now I want to do something a little complicated, i.e. proxy a NodeJS instance like so:

<VirtualHost foobar.example.com:80>
 <Location />
   ProxyPass http://localhost:3000/
   ProxyPassReverse http://localhost:3000/
 </Location>
</VirtualHost>

And it doesn't work. Apache just serves /srv/www/foobar.example.com. If I put the "VirtualHost foobar.example.com" stanza above the VirtualDocumentRoot one, then everything gets redirected to the proxy, which I don't want.

I just want the particular domain "foobar.example.com" handled by the proxy, and everything else, the VirtualDocumentRoot.

    What you're looking to configure is name-based virtual hosting, where the virtual host is selected based on the Host header sent in the HTTP request by the client.

    To do this, you'll need a NameVirtualHost directive, and for your <VirtualHost> blocks to match exactly to what you've configured in it. For instance:

    NameVirtualHost *:80
<VirtualHost *:80>
  ServerName default
  VirtualDocumentRoot /srv/www/%0
  # other needed config directives here
</VirtualHost>
<VirtualHost *:80>
  ServerName foobar.example.com
  <Location />
    ProxyPass http://localhost:3000/
    ProxyPassReverse http://localhost:3000/
  </Location>
</VirtualHost>
