Install Ruby with apt-get
1. Make sure the universe repository in /etc/apt/sources.list is uncommented:
deb
http://us.archive.ubuntu.com/ubuntu/ edgy universe
deb-src
http://us.archive.ubuntu.com/ubuntu/ edgy universe
Also uncomment the security lines
deb
http://security.ubuntu.com/ubuntu edgy-security universe
deb-src
http://security.ubuntu.com/ubuntu edgy-security universe
2. Make sure you are up to date:
sudo apt-get update
sudo apt-get dist-upgrade
3. Install the ruby and mysql base packages:
sudo apt-get install ruby ri rdoc mysql-server libmysql-ruby
4. We need to grab the latest ruby gems from rubyforge. You may need to modify this command if a version after 0.9.2 is available.
sudo wget
http://rubyforge.org/frs/download.php/17190/rubygems-*.*.*.tgz
tar -xvzf rubygems-*.*.*.tgz
cd rubygems-*.*.*.tgz
sudo ruby setup.rb
5. Now let's install Ruby on Rails!
sudo gem install
rails --include-dependencies
[edit] Install Ruby and Rails from source
1. Download source code of Ruby, RubyGems
wget
ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.7-p22.tar.bz2
wget
http://rubyforge.org/frs/download.php/35283/rubygems-1.1.1.tgz
tar -zxvf ruby-1.8.7-p22.tar.bz2 --directory=~/dev.dir/ruby/
tar -zxvf rubygems-1.1.1.tgz --directory=~/dev.dir/ruby/
2. Install Ruby
cd ~/dev.dir/ruby/ruby-1.8.7-p22
./configure
make
make test
sudo make install
To verify that you have a current version of Ruby, run the command ruby --version
3. Install RubyGems
cd ~/dev.dir/ruby/rubygems-1.1.1
sudo ruby setup.rb config
sudo ruby setup.rb setup
sudo ruby setup.rb install
4. Install Rails.
sudo gem install rails --include-dependencies
5. Issues you may ran into... If you get some output like:
[...] /usr/local/lib/ruby/site_ruby/1.8/rubygems/remote_fetcher.rb:4:in `require’: no such file to load — zlib (LoadError) [...]
The fix:
To be on the safe side be certain that zlib is installed:
$ sudo apt-get install zlib zlib-devel
$ cd ~/dev.dir/ruby/ruby-1.8.7-p22/ext/zlib/
$ ruby extconf.rb --with-zlib-include=/usr/include --with-zlib-lib=/usr/lib
$ make
$ make install
Then re-install RubyGems, the issue may solved.
