usermod -a -G rvm root
# TODO No longer works, new method of install
# Install RVM (system wide)
\curl -L https://get.rvm.io | sudo bash -s stable
# Add this line to the end of any user who needs access to RVM's .bash_profile
# this will add it to the end of the current user's profile
echo '[[ -s "/usr/local/lib/rvm" ]] && . "/usr/local/lib/rvm" # This loads RVM into a shell session.' >> ~/.bash_profile
source ~/.bash_profile
type rvm | head -1 # should print 'rvm is a function'
# I ran this to install ruby dependencies, as per instructions in `rvm notes`
sudo yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel
# Install Ruby 1.9.3
sudo rvm install 1.9.3

# Now, install Rails and Passenger
gem install rails passenger

rvmsudo passenger-install-nginx-module
# Set up a nginx init script -- I used the one found here: http://articles.slicehost.com/2009/2/2/centos-adding-an-nginx-init-script
# and modified the nginx and NGINX_CONF_FILE variables to point to my nginx install (which is in /opt/nginx)
cd /etc/init.d
sudo wget -O nginx http://bit.ly/8XU8Vl
sudo chmod +x nginx
# set nginx to start automatically when the server restarts
sudo /sbin/chkconfig nginx on
