Rails - May 2006 - Ruby on Rails on Linux - Any suggestions/Help?

Hi, I''m really new to RoR and I''m trying to setup a
development or even
production server for Ruby on Rails.

I''m trying to do it on Linux Debian, but somehow, I always get this
Error:

 

Application Error - Rails application failed to start properly

 

This was running on Debian Linux, Apache2, Mysql and FastCGI.

The Tutorial I used:
http://o9y.net/archives/2006/02/17/ruby-on-rails-mittels-mod_fcgi-fur-apache
-2-unter-debian/ (German)

 

Well, I installed everything as described in one of those many tutorials on
the net, but I don''t get it to work.

 

Maybe someone has some tips I schould do to get it work? Or maybe someone
might tell me what Setup might be the best on Linux???

I always worked with Debian, but I could switch to any other if someone
tells me which might be the best for this task.

 

Thanks

 

-Georges

Check your logs, development.log for rails and the apache logs.  Try
your app in webrick.

Please list versions you are running:

ruby -v
rails -v

I would suggest getting ruby installed, then install gems, then use
gems to install rails.

Test your ruby on rails install with webrick, a small web server
written in ruby that comes with rails. This will tell you that Ruby
and Rails are installed and working.

Once Ruby, gems, and Rails are installed and working, then start on
Apache, MySQL, and FastCGI.

This seperation of steps will make it more clear where the problem(s) lies.

Good Luck,

-Sean

Well,

It seems that there might be a problem with my FastCGI installation for
Apache. This is in my log/error.log from my rails Project:

FastCGI: incomplete headers (0 bytes)



ruby 1.8.2 (2005-04-11) [i386-linux]
Rails 1.1.2

Hi Georges,

I use Debian/testing (2.6.8-2-386) and I have a protocol to set up an
application with virtual hosts (Apache) Is in spanish (don''t have too
much time in this moment to translate it, sorry) see it attached below:


1. Tomamos como ejemplo el tutorial Four days on rails
2. Como root en /var/www/:
         #rails ToDo
3. Con el phpnyadmin creamos la base de datos ''todos'' y la
tabla
''categories''
4. En /var/www/ToDo/ (de ahora en adelante ~/ToDo) hacemos:
         #ruby script/generate scaffold category
5. Editamos ~/ToDo/config/database.yml y ponemos:

         development:
         adapter: mysql
         database: todos
         username: root
         password:
         socket: /var/run/mysqld/mysqld.sock

6. Editamos ~/ToDo/public/.htaccess y quitamos el s?mbolo ''#''
de las
l?neas sgtes.:

         RewriteCond %{REQUEST_URI} ^/notrails.*
         RewriteRule .* - [L]
         RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
         RewriteEngine On

         Dejamos el resto tal como est?

7. En /etc/apache2/sites-available/default introducimos al final:

         <VirtualHost *>
         ServerName todo
         DocumentRoot /var/www/ToDo/public
         ErrorLog /var/www/ToDo/log/apache.log
         <Directory /var/www/ToDo/public/>
         Options +ExecCGI +FollowSymLinks
         AddHandler fcgid-script .fcgi
         AllowOverride all
         Order allow,deny
         Allow from all
         </Directory>
         </VirtualHost>

8. En /etc/apache2/apache2.conf quitamos el s?mbolo ''#'' de la
l?nea:

         AddHandler fastcgi-script .fcgi .fcg .fpl

9. No olvidar reiniciar el servidor apache cuando hagamos cualquier cambio:

         #apache2ctl restart

10. No olvidar a?adir en /etc/hosts el nombre del nuevo host (todos) y
tampoco de los permisos en /var/www/todos/ de forma: chmod -R 777 * /todos


Hope this helps

Antonio

Apache2 does not play nicely with mod_fastcgi. You need mod_fcgid.
Conveniently, this involves just apt-get install libapache2-mod-fcgid.

http://o9y.net/archives/2006/02/17/ruby-on-rails-mittels-mod_fcgi-fur-apache-2-unter-debian/

[...]

I don''t know German, I''m afraid, but it appears that the
tutorial is having
you build mod_fastcgi yourself. I''m not sure why, since it is available
precompiled as a Debian package. More to the point, it doesn''t work
particularly well with Apache2.

} Maybe someone has some tips I schould do to get it work? Or maybe someone
} might tell me what Setup might be the best on Linux???

Apache2 is fine. Debian is great. MySQL... eh, to each his own. FastCGI is
a good choice in other environments, but you need mod_fcgid. A quick Google
search for mod_fcgid and rails gives a number of pages with useful
information. That said, here''s what I have in
/etc/apache2/sites-available/default (note that this is for an app running
at a path on a main server rather than as its own virtual host, as shown on
the Alias line):

<IfModule mod_fcgid.c>
	DefaultInitEnv RAILS_ENV production
	Alias /bookmarkfeeds /home/gss/work/ruby/bookmarkfeeds/public
	<Directory "/home/gss/work/ruby/bookmarkfeeds/public">
		Options ExecCGI +FollowSymLinks
		AllowOverride All
		order allow,deny
		allow from all
		RedirectMatch ^/bookmarkfeeds/$ /bookmarkfeeds/feeds/
		RedirectMatch ^/bookmarkfeeds$ /bookmarkfeeds/feeds/
	</Directory>
</IfModule>

Note that those last two RedirectMatch lines are specific to my app, and
don''t apply in general. And yes, I am running it out of my home
directory,
because I feel like it. In addition, I had to modify the
RAILS_ROOT/public/.htaccess file to change the following two lines (they
are not contiguous in the file):

AddHandler fastcgi-script .fcgi
RewriteRule ^(.*)$ dispatch.cgi [QSA,L]

...to...

AddHandler fcgid-script .fcgi
RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]

Finally, since I have this running at /bookmarkfeeds instead of at / I
needed this line in the .htaccess file as well:

RewriteBase /bookmarkfeeds

} I always worked with Debian, but I could switch to any other if someone
} tells me which might be the best for this task.

There will always be people who think that their system is better than
yours. I can assure you that it is possible and even moderately easy to get
mod_fcgid working with Rails and Apache2 under Debian. I''ve done it. I
have
it running on my own machine.

} Thanks
