apache virtualhosts subdomains

In this post I will show how to configure several virtual hosts on a linux machine, that will function as subdomains with their own DocumentRoots.

Goal:

• access your site via blog.mysite.com
• access a different site via test.mysite.com
• allow different app to be accessable via mysite.com/app1

First you will have to redirect any traffic to a virtual host on port 80:

NameVirtualHost *:80

From now on every 'html' traffic is redirected to your following settings; and have in mind that you former DocumentRoot is overridden.
(the last caused me some troube/time)

Now set up some subdomains:

 <VirtualHost *:80>  
  ServerName blog.mysite.com
  ServerAdmin webmaster@mysite.com  
  DocumentRoot /var/www/html/blog 
 <Directory /var/www/html/blog>  
         Options Indexes FollowSymLinks MultiViews  
         AllowOverride All  
         Order allow,deny  
         allow from all  
 </Directory>  
 </VirtualHost> 

 <VirtualHost *:80>  
  ServerName test.mysite.com
  ServerAdmin webmaster@mysite.com  
  DocumentRoot /var/www/html/test
 <Directory /var/www/html/test>  
         Options Indexes FollowSymLinks MultiViews  
         AllowOverride All  
         Order allow,deny  
         allow from all  
 </Directory>  
 </VirtualHost> 

At last you have to make sure you still can access mysite.com/app1
(in a subfolder of html)

<VirtualHost *:80>  
  ServerName mysite.com
  ServerAdmin webmaster@mysite.com  
  DocumentRoot /var/www/html
 <Directory /var/www/html>  
         Options Indexes FollowSymLinks MultiViews  
         AllowOverride All  
         Order allow,deny  
         allow from all  
 </Directory>  
 </VirtualHost> 

 With these settings my server runs problemfree and I am just waiting for my fist rails app to be deployed in order to test the vhost settings for passenger.

Have fun!
