    <p>I want to run rails 3 and rails 2.3.8 apps on the same machine. I currently have Passenger setup with Ruby 1.9.2 for my rails 3 apps and that is working fine with Apache. I found the following at the Phusion website and am trying out the reverse proxy :</p> <p><a href="http://blog.phusion.nl/2010/09/21/phusion-passenger-running-multiple-ruby-versions/" rel="nofollow noreferrer">http://blog.phusion.nl/2010/09/21/phusion-passenger-running-multiple-ruby-versions/</a></p> <p>My Apache vhost file for this app looks like:</p> <pre><code>&lt;VirtualHost *:80&gt; ServerName gtt DocumentRoot /home/purvez/www/gtt/public RailsEnv development PassengerEnabled off ProxyPass / http://127.0.0.1:3000 ProxyPassReverse / http://127.0.0.1:3000 &lt;/VirtualHost&gt; </code></pre> <p>I can correctly access the app using passenger standalone using:</p> <pre><code>127.0.0.1:3000/start </code></pre> <p>but when I try to access it as :</p> <p><code>http://gtt/start</code></p> <p>I get a message saying:</p> <p>No route matches [GET] "/start"</p> <p>The Apache 'other_vhosts_access.log' however shows this entry:</p> <pre><code>testapp:80 127.0.0.1 - - [20/Oct/2011:15:27:58 +0100] "GET /start HTTP/1.1" 404 737 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:7.0.1) Gecko/20100101 Firefox/7.0.1" </code></pre> <p>As you can see it is trying to call testapp:80 rather than gtt:80. I have both these in my /etc/hosts file and in fact gtt is BEFORE testapp!</p> <p>What am I doing wrong here and how to put it right?</p> <h2>Edit</h2> <p>I am mega embarrassed! I had not enabled the site on Ubuntu and hence it was looking at the only available site i.e. testapp.</p> <p>However having corrected the problem I'm still getting a 500 Error. The 'other_vhosts_access.log' entry shows:</p> <pre><code>gtt:80 127.0.0.1 - - [20/Oct/2011:18:07:30 +0100] "GET /start HTTP/1.1" 500 599 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:7.0.1) Gecko/20100101 Firefox/7.0.1" </code></pre> <p>It's almost like the proxy to Passenger standalone is not happening and that Apache is trying to get start itself. Certainly the passenger.3000.log (i.e. standalone Passenger log) is showing no activity at all!</p> <p>So having made a monumental blunder and wasted everyone's time initially I'm still in the same boat in that it looks like the Proxy is not happening!!</p> <p>Anyone got any ideas?</p>

    1. CODo you have a "NameVirtualHost *:80" rule in your Apache config? This is what tells Apache to use the ServerName instead of the first matching VirtualHost.

    2. COThere is a NameVirtualHost *:80 entry in ports.conf as follows: NameVirtualHost *:80 Listen 80 Would that make a difference?

    3. COI believe that is correct. You may want to retag your post with Apache as well, as it appears that this isn't a Rails specific issue, but rather an issue with how Apache is routing the traffic.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
