Ruby on Rails
FastCGI on unix linux bsd (Version #2)

Here’s a step-by-step guide for making Rails work with \FastCGI?. There’s a special version for \FastCGIOnFedora

If you are using Apache you will need mod_fcgi, and the \FastCGI Development kit; These can be obtained from http://www.fastcgi.com . You will also need ruby-fcgi.

Install the FastCGI? Devel kit.

$ wget <a href="http://fastcgi.com/dist/fcgi-2.4.0.tar.gz">http://fastcgi.com/dist/fcgi-2.4.0.tar.gz</a> 
$ tar zxvf fcgi-2.4.0.tar.gz
$ cd fcgi-2.4.0
$ ./configure
$ make
$ sudo make install</pre>

Install ruby-fcgi (note that on some systems this won’t work right unless you’ve installed the Devel kit first).
```
$ sudo gem install fcgi</pre>
```

Download and install mod_fcgi from your distributions package management system of choice (\ToDo: expand on this)

Add the following to your apache httpd. conf

LoadModule fastcgi_module /usr/lib/apache2/modules/mod_fastcgi.so
<IfModule mod_fastcgi.c>
    FastCgiIpcDir /tmp/fcgi_ipc/
    AddHandler fastcgi-script .fcgi
</IfModule></pre>

You may have mod_fastcgi.so installed in a different place. If so, use the correct path.

Reload apache with

$ apache2ctl reload</pre>

Use apachectl if you are not using apache2

Change directories to your rails app

In public/dispatch.fcgi change:

require 'fcgi'</pre>

to

require 'rubygems'
require_gem 'fcgi'</pre>

In public/.htaccess change:

RewriteRule ^(.*)$ /dispatch.cgi?$1 [QSA,L]</pre>

to

RewriteRule ^(.*)$ /dispatch.fcgi?$1 [QSA,L]</pre>
