Installing fcgid with suexec AND phusion passenger

It was a troublesome day today. All did not go as planned.

I had to install fcgid + suexec on one of our servers, I had delayed it too long. So I used my how-to and it still worked flawless. But I noticed I hadn’t mentioned what the right were of the suexec binary. So here it goes:

chown root:www-data suexec
chmod 4754 suexec

After the install I restarted Apache and looked at one of the sites. And it worked! I was baffled. That’s the first time I installed fcgid without hours long of searching where the flaw was.

But then I looked at our support system (Redmine) and it didn’t work too well

All controllers were being executed ‘n stuff. But the stylesheets, images and javascripts were not loaded. When requesting an image in the browser I got Rails 404-error page. Huh? Apache should have handled that request. At first I thought it was because of some changes I made to the virtualserver configuration of an other Rails site. But after some trial and error I couldn’t find anything that was wrong.

Then I removed the .htaccess from the public directory of Redmine. That once worked for one of my rails sites. But no cigar. Then I noticed that there were a lot of dispatch*example.rb’s in the public directory. And: after removing them, the stuff worked. So it seems like Rails or Phusion Passenger uses some kind of fuzzy matching when searching for a dispatch.rb. And it first just worked because fcgid was not installed. So I don’t know who’s to blame. But the problem is solved. Phew!
