Installing Rails @ Amazon Linux

gistfile1.md

Steps

• Build tools:

    sudo yum groupinstall "Development Tools"
  

• Dependencies:

    yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel \
    libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison iconv-devel
  

• Install RVM

    bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
  

• Install Ruby

    rvm install 1.9.2
  

• Install Rails, Bundler (problem was here)

    gem install bundler --no-rdoc --no-ri
    gem install rails --no-rdoc --no-ri
  

• MySQL

    sudo yum install sqlite3-dev
  

• Node JS

    wget http://nodejs.org/dist/v0.6.15/node-v0.6.15.tar.gz
    tar -xf node-v0.6.15.tar.gz 
    cd node-v0.6.15
    ./configure
    sudo make install
  

Shortcut way to try out:

sudo yum localinstall --nogpgcheck http://nodejs.tchol.org/repocfg/fedora/nodejs-stable-release.noarch.rpm
sudo yum install nodejs

Problem #1:zlib

Symptoms

[ec2-user@domU-12-31-38-04-80-4D zlib]$ gem install rails --include-dependencies
    ERROR:  Loading command: install (LoadError)
        no such file to load -- zlib
    ERROR:  While executing gem ... (NameError)
        uninitialized constant Gem::Commands::InstallCommand

Solution

Originally taken from here

cd /home/ec2-user/.rvm/src/ruby-1.9.2-p320/ext/zlib
ruby extconf.rb --with-zlib-include=/usr/include --width-zlib-lib=/usr/lib
make 
sudo make install
gem install rails --include-dependencies

Problem #2: openssl

Originally taken from here

cd /home/ec2-user/.rvm/src/ruby-1.9.2-p320/ext/openssl
ruby extconf.rb
make
make install

Steps for CentOS(less painful btw):
Setup EPEL
rpm -Uhv http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
All Supplemental Packages
yum install gcc gcc-c++ mysql-devel libxml2-devel libxslt-devel libssl-devel zlib zlib-devel openssl
RVM install
bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
echo ' -s "$HOME/.rvm/scripts/rvm" && . "$HOME/.rvm/scripts/rvm" # Load RVM function'>>~/.bash_profile

Ruby install
rvm pkg install openssl
rvm install 1.9.3 --with-openssl-dir=$rvm_path/usr
rvm use ruby-1.9.3 --default
gem install bundle
gem install rails

In order to run the nokogiri gem, I also installed the xml libraries for Amazon Linux:

sudo yum install -y gcc ruby-devel libxml2 libxml2-devel libxslt libxslt-devel
