# 
# Ubuntu 14.04 based web server installation script
# Run this by executing the following from a fresh install of Ubuntu 14.04 server:
# 
#     bash -c "$(curl -fsSL https://gist.githubusercontent.com/simkimsia/0fe0a5eb9c7504ead53c/raw/58438c9a7c132be94fe5d6687b6f9623968b927f/ubuntu14.04-rails4.sh)" <mysqlPassword>
# 
# Be sure to replace <mysqlPassword> with your intended MySQL Password.
# Also, run this as root, unless you enjoy failing.
# 
# Its handy to install 'screen' if you want to ensure your remote connection to
# a server doesn't disrupt the installation process. If you want to do this, just
# do the following before running the main bash command:
# 
#     apt-get install screen -y
#     screen
# 
# To recover your session if you are disconnected, ssh to your server as root again,
# and type:
# 
#     screen -x
# 
# Dependencies:
# - curl
# 
# Todo:
# - SSL Configuration
#

## Install RVM first 
## Note the backslash before “curl” (this avoids potential version conflicts).
## The "—ruby" flag will install the newest version of Ruby.
########################################
\curl -L https://get.rvm.io | bash -s stable --ruby

########################################
## To start using RVM you need to run `source /usr/local/rvm/scripts/rvm`
## in all your open shell windows, in rare cases you need to reopen all shell windows.

## The JavaScript runtime is required to compile code for the Rails asset pipeline.
########################################

########################################
## If you install Rails at this point, you will install it into the global gemset.
## Instead, make a gemset just for the current stable release:

gem install rails
