How to publish a Rails application

Assuming the name of the Rail Application is newrail and the location for all new Rail Applications is /var/rails, thus a Rail Application can be published in 2 ways:

• Via Builtin Webserver, called WEBrick by running </script/server located in the folder where it was created.

cd /var/rails/newrail/script
./server &

• Via Apache Web Server by setting the proper [[DocumentRoot]] varible with the location of the public folder in the Rail Application

DocumentRoot /var/rails/newrails/public

<Directory /var/rails/newrails/public>
    Options ExecCGI FollowSymLinks
    AddHandler cgi-script .cgi
    AllowOverride all
    Order allow,deny
    Allow from all
</Directory>
