Why did Apache stop working after adding two sites?

Question

I wanted both Redmine and Mercurial on localhost/redmine and localhost/mercurial.

Redmine is a RoR application that runs on mod_passenger module and mercurial runs on a CGI script. I should be able to use both on a single server right?

I got Redmine to work fine. Then I followed the steps for Mercurial. Then I enabled that site.

And neiter site works. I did a2ensite those two sites and restarted Apache, but both domains now give me a 404.

Great question, the problem is that you have a different ServerName in each of your sites. Apache will look for this in the URL line, so for mercurial you'd have to go to

http://mercurial.server/....

And for redmine you have to go to

http://myservername/...

Since you want them both to live in the same hostname, you probably just need one VirtualHost tag to define the DocumentRoot and desired ServerName, and then the aliases and such that you want under that host. This will all be simpler if it lives as one "site" configuration.
