ubuntu_ROR_Apache2
==================

How To configure Apache to run ROR

1, Install LAMP and other packages

apt-get install apache2 mysql-server libapache2-mod-auth-mysql php5-mysql  php5 libapache2-mod-php5 php5-mcrypt

apt-get install libcurl4-openssl-dev apache2-threaded-dev libapr1-dev libaprutil1-dev

2, Remove old  Ruby

  apt-get remove ruby1.9.1

  apt-get remove ruby1.8

3 Install RVM (for ubuntu)

  apt-get --purge remove ruby-rvm

  rm -rf /usr/share/ruby-rvm /etc/rvmrc /etc/profile.d/rvm.sh

 env | grep rvm

  \curl -L https://get.rvm.io | bash -s stable --ruby --autolibs=enable --auto-dotfiles

source /usr/local/rvm/scripts/rvm

rvm

4, Install Rails

gem install rails

5, Ruby versions (by Feb. 15 2014)

  ruby 2.1.0p0 (2013-12-25 revision 44422) [i686-linux]
 
  gem 2.2.2
 
  irb 0.9.6(09/06/30)
 
  rvm 1.25.18 (stable)
 
  Rails 4.0.2
 
  rake (10.1.0)

6,install Phusion Passenger.

DO NOT USE APT-GET TO INSTALL PASSENGER, OTHERWISE, RUBY WILL BE DOWNGRADED TO LOWER VERSION, AND RAILS WILL NOT WORK.
  #apt-get install libapache2-mod-passenger

gem install passenger

passenger-install-apache2-module

passenger start

Please edit your Apache configuration file, and add these lines:

vim /etc/apache2/apache2.conf

   LoadModule passenger_module /usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.37/buildout/apache2/mod_passenger.so
   <IfModule mod_passenger.c>
     PassengerRoot /usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.37
     PassengerDefaultRuby /usr/local/rvm/gems/ruby-2.1.1/wrappers/ruby
   </IfModule>

7, update apache2 config file (assume your rails application path is /opt/ruby/demo/)

  vim /etc/apache2/sites-available/default

  <VirtualHost x.x.x.x:80>
        ServerAdmin xxng@gmail.com

        ServerName  3w.com
        ServerAlias www.3w.com

        RailsEnv development
        DocumentRoot /opt/ruby/demo/public

        <Directory /opt/ruby/demo/public>
               AllowOverride all
               Options -MultiViews
        </Directory>

  </VirtualHost>

8,    service apache2 restart
