getting ruby, rails, passenger on my centos box

Do not yum for ruby, cause you’ll get 1.8.5.
Follow these steps to get everything installed:

Then create a passenger virtualhost:

DocumentRoot /var/www/railstest/public
ServerName railstest.cosninix.com
RailsBaseURI    /
 RailsEnv development
 &lt;Directory "/var/www/railstest/public"&gt;
    allow from all
    Options -MultiViews

DocumentRoot /var/www/railstest/public

ServerName railstest.cosninix.com

RailsBaseURI /

RailsEnv development

allow from all

Options -MultiViews

Watch: railsEnv is mandatory! This is not in the passenger doc but gives you a 500-internal server error if missing.

Now go to /var/www and create your rails app (and use mysql as well)

rails new railstest -d mysql

restart httpd and we should see the generated index.html, but that is still static html processed so no rails nor ruby is actually used.

Now remove index.html from railstest/public and generate a test controller:

rails generate controller home index

And change the default route (config/routes.rb) for the root: (search for root, it is already there but commented out)

Blog::Application.routes.draw do

root :to => "home#index"

now restart httpd and you should see rails at work.

Then it might be nice to have a sinatra setup as well.

Create another virtual server, this time it is called sinatratest:

&lt;VirtualHost *:80&gt;
 DocumentRoot /var/www/sinatratest/public
 ServerName sinatratest.cosninix.com

 RackEnv production

 &lt;Directory "/var/www/sinatratest/public"&gt;
 allow from all
 Options -MultiViews
 &lt;/Directory&gt;
&lt;/VirtualHost&gt;

DocumentRoot /var/www/sinatratest/public

ServerName sinatratest.cosninix.com

RackEnv production

allow from all

Options -MultiViews

</Directory>

</VirtualHost>

Also here, the RackEnv is mandatory!

Now create the sinatratest dir and a public dir.

Leave the public dir empty, it is a placeholder for now but can be filled with javascript files and css etc.

Create a file called config.ru in the sinatratest dir (this is a rack definition file that passenger accepts)

require 'rubygems'

1	require 'rubygems'

require 'sinatra'

1	require 'sinatra'

set :environment, :production

1	set :environment, :production

disable :run, :reload

1	disable :run, :reload

require 'testje'

1	require 'testje'

run Sinatra::Application

1	run Sinatra::Application

This is for the latest sinatra version (1.2.0) as some methods has changed names and/or became class methods.

now create a small file testje.rbin (also in the sinatratest dir)

get '/' do

1	get '/' do

   "hello world, my name is Frank"

1	"hello world, my name is Frank"

end

end

Restart httpd and this should work. You now have a working rails and sinatra deployment on centos with passenger.

One tip: Instead of restarting httpd all the time it is easier to create a tmp dir and use

touch tmp/restart.txt

1	touch tmp/restart.txt

every time you changed something. This will trigger passenger to reload everything
