Steps to install RVM + Ruby 1.9.2 + Rails + nginx + Passenger on CentOS (tested on v5.5)
# Steps to install RVM + Ruby 1.9.2 + Rails + nginx + Passenger on CentOS (tested on v5.5)
# Install git and curl, if not already installed
sudo yum install git
sudo yum install curl
# Create the rvm group and add any users who will be using rvm to the group
sudo su -
groupadd rvm
# Start by adding the root user (required to install RVM)
usermod -a -G rvm root
# Then add any other users who need access to to the rvm group and logout of the superuser account
logout
# Install RVM (system wide)
sudo bash < <( curl -L http://bit.ly/rvm-install-system-wide )
# Logout, then log back in (I found that my user did not belong to the RVM group until I did this)
logout
# Now that you have RVM installed, follow post-install instructions here: http://rvm.beginrescueend.com/rvm/install/
# * but change the RVM path to /usr/local/lib/rvm
# 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 1.9.2
sudo rvm install 1.9.2
# Set the RVM default to 1.9.2
rvm --default use 1.9.2
ruby -v # should return the version of ruby we're using
# Now, install Rails and Passenger
gem install rails -v '3.1.1' -no-rdoc --no-ri passenger
# Install nginx with Passenger support. Press 1 when prompted
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
# the mysql gem requires mysql-devel
sudo yum install mysql-devel
gem install mysql
# the pg gem requires postgresql-devel
sudo yum install postgresql-devel
gem install pg
