Originally, I had rails running under apache with fastcgi.

I just recently successfully installed mod\_rails and updated my apache  
httpd.conf file with the correct configuration but kept my virtual host  
the same.

i’m a little confused about a couple things here though:

-does fastcgi need to be installed to run a mod\_rails instance?

-how can i tell if i am actually using mod rails or just running under  
fastcgi?

do:

curl --head [http://yourwebsitename](http://yourwebsitename)

You should have

X-Powered-By: Phusion Passenger (mod\_rails/mod\_rack) 1.1.0

or similar if mod\_rails is being used 🙂

hmm…

here is the ouptut

curl --head [http://wl.kuliksco.com](http://wl.kuliksco.com)

HTTP/1.1 200 OK  
Date: Thu, 26 Jun 2008 13:50:27 GMT

i noticed there were still lots of fastcgi processes so i killed them  
all and restarted apache. now the only ruby process is:

/usr/local/lib/ruby/gems/1.8/gems/passenger-2.0.1/ext/apache2/ApplicationPoolServerExecutable  
0  
/usr/local/lib/ruby/gems/1.8/gems/passenger-2.0.1/bin/passenger-spawn-server  
/usr/local/bin/ruby /tmp/passenger\_status.2744.fifo

and the website is working so i’m assuming everything is working.
