Install ruby 1.9.3-p125 from source

On ubuntu server 10.04 you might want to avoid rvm and rbenv and just go straight for installing ruby on your server.

Install openssl development libraries and prerequisites.

sudo apt-get -y install build-essential libssl-dev libreadline5-dev zlib1g-dev

Install yaml

#!/bin/bash cd /usr/srcsudo wget http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gzsudo tar xvzf yaml-0.1.4.tar.gzcd yaml-0.1.4sudo ./configure --prefix=/usr/localsudo make sudo make install

Install ruby

#!/bin/bash cd /usr/srcsudo wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p125.tar.gzsudo tar xvzf ruby-1.9.3-p125.tar.gzcd ruby-1.9.3-p125sudo ./configure --prefix=/usr/local --enable-shared --disable-install-doc --with-opt-dir=/usr/local/lib --with-openssl-dir=/usr --with-readline-dir=/usr --with-zlib-dir=/usrsudo makesudo make install

Install rubygems

  !#/bin/bash   cd /usr/src   sudo wget http://production.cf.rubygems.org/rubygems/rubygems-1.8.17.tgz  sudo tar xvzf rubygems-1.8.17.tgz  cd rubygems-1.8.17  sudo ruby setup.rb

This is applicable if you want to run a certain version of ruby globally on your production server. If there is alreadt a version of ruby installed, check /usr/bin/ruby, /usr/bin/gem and /usr/bin/bundle and update the links accordingly.

eg.

  sudo rm /usr/bin/ruby; sudo ln -s /usr/local/bin/ruby /usr/bin/ruby  sudo rm /usr/bin/gem; sudo ln -s /usr/local/bin/gem /usr/bin/gem  sudo gem install bundler --pre  sudo rm /usr/bin/bundle; sudo ln -s /usr/local/bin/bundle /usr/bin/bundle

Happy compiling!
