RVM and Bundler on Dreamhost

1 - setting up RVM.sh

#
# Step One - Installing RVM
#

curl -L https://get.rvm.io | bash -s stable --ruby

# Then, install ruby 1.8.7 -- you need to basically match the same version of Ruby as Dreamhost

rvm install ruby-1.8.7-p334

#
# I also create a gemset, although this is probably optional
#
rvm gemset create sinatra 
rvm use 1.8.7@sinatra

# My project has this very simple .rvmrc
rvm 1.8.7@sinatra


# Install bundler next:

gem install bundler

2 - setup Gemfile

#
# Step Three - Setup Gemfile
#

# In your Gemfile, you will need to match the version of rack being used on Dreamhost, which is currently 1.2.1:

gem "rack", "=1.2.1"

3 - setup config.ru

#
# Step Three - Setup config.ru
#

#!/usr/bin/env ruby

require 'rubygems'

ENV['GEM_HOME']="/home/username/.rvm/gems/ruby-1.8.7-p334@sinatra"
ENV['GEM_PATH']="/home/username/.rvm/gems/ruby-1.8.7-p334@sinatra:/home/username/.rvm/gems/ruby-1.8.7-p334@global"

require 'rubygems'
Gem.clear_paths

require 'bundler'
Bundler.require

require 'mufftweet'
run MuffTweet

4 - vendored bundle.sh

#
# Recently I had some problems with my apps on Dreamhost, and I switched to using 
# a vendored bundle. I ran this command within each of my projects:
#

bundle install --path vendor

# This installs the gems you need in a vendor/ folder within your project.

5 - running cron commands.sh

# Finally, if you need something to run in cron, you can do it like this:
# The ". ~/.bash_profile" bit loads in the RVM functions that you will need to run anything in cron.

*/10 * * * * . ~/.bash_profile; cd /home/username/appname; /home/username/appname/cron.rb
