I wanted to get started with Ruby on Rails development and while there is a ruby package in the ubuntu repositories, I wanted to compile it from source. I feel more in control that way ;) These are the steps I went through to get up and running with a rails stack.
First, Install prerequisites:
sudo apt-get -y install build-essential libssl-dev libreadline5-dev zlib1g-dev
Downloaded ruby 1.8.7 source:
Extract the contents:
tar -xzf ruby-1.8.7-p174.tar.gz
Configure the source:
./configure --prefix=/usr/local/ruby-1.8.7 --with-openssl-dir=/usr/lib \ --with-readline-dir=/usr/lib --with-zlib-dir=/usr/lib
Test the Ruby interpreter. This will check whether the compiled Ruby Interpreter works well. If all went well you should see “test succeeded”:
sudo make install
Make a symlink to ruby:
sudo ln -s /usr/local/ruby-1.8.7/bin/ruby /usr/bin/ruby
Test ruby to make sure its working. You should get a “success” message.
ruby -ropenssl -rzlib -rreadline -e "puts :success"
Download Ruby Gems:
cd /tmp wget http://rubyforge.org/frs/download.php/60718/rubygems-1.3.5.tgz
tar -xzf rubygems-1.3.5.tgz
sudo ruby setup.rb
Make a symlink to gems:
sudo ln -s /usr/local/ruby-1.8.7/bin/gem /usr/bin/gem
sudo gem install rails
Make a symlink to rails:
sudo ln -s /usr/local/ruby-1.8.7/bin/rails /usr/bin/rails
Rails is now installed!
We still need to install a few more things. Rails by default uses sqlite as a database backend so make sure it’s installed:
sudo apt-get install sqlite3 libsqlite3-dev
Next we need to install the rake gem:
sudo gem install rake
Create a symlink to rake:
sudo ln -s /usr/local/ruby-1.8.7/bin/rake /usr/bin/rake
Now we need to install the ruby bindings for sqlite3 (NOTE: you may get a few warnings at this step but it still installs and runs fine)
sudo gem install sqlite3-ruby
That should be it! Your RoR stack on Ubuntu should be complete. Code away!
