Teniendo instalado rails3 y apache2 vamos a instalar passenger
$ gem install passenger
$ gem passenger-install-apache2-module
passenger irá guiando la instalación, si necesita dependencias y mostrara las lineas que hay que agregar a los archivos de configuración de apache
Please edit your Apache configuration file, and add these lines:
LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.2-p180/gems/passenger-3.0.7/ext/apache2/mod_passenger.so
PassengerRoot /usr/local/rvm/gems/ruby-1.9.2-p180/gems/passenger-3.0.7
PassengerRuby /usr/local/rvm/wrappers/ruby-1.9.2-p180/ruby
terminará con un mensaje similar a este
Suppose you have a Rails application in /somewhere. Add a virtual host to your
Apache configuration file and set its DocumentRoot to /somewhere/public:
<VirtualHost *:80>
ServerName www.yourhost.com
DocumentRoot /somewhere/public # <-- be sure to point to 'public'!
<Directory /somewhere/public>
AllowOverride all # <-- relax Apache security settings
Options -MultiViews # <-- MultiViews must be turned off
</Directory>
</VirtualHost>
And that's it! You may also want to check the Users Guide for security and
optimization tips, troubleshooting and other useful information:
moverse al archivo de los mods de apache
$ cd /etc/apache2/mods-available
crear el archivo passenger.conf y agregar las lineas antes mostradas
y passenger.load
LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.2-p180/gems/passenger-3.0.7/ext/apache2/mod_passenger.so
subir el modulo y reiniciar apache
$ sudo a2enmod passenger
$ sudo /etc/init.d/apache2 restart
crear el archivo de virtualhost
<VirtualHost *:80>
ServerName www.yourhost.com
DocumentRoot /somewhere/public # <-- be sure to point to 'public'!
<Directory /somewhere/public>
AllowOverride all # <-- relax Apache security settings
Options -MultiViews # <-- MultiViews must be turned off
</Directory>
</VirtualHost>
Este es un punto importante, public debe ser el directorio public de la aplicación creada por rails.
