1、install ruby
apt-get install irb libdbm-ruby1.8 libgdbm-ruby1.8 libmysql-ruby1.8 libmysqlclient14 libopenssl-ruby1.8 libruby1.8-dbg mysql-common ri ri1.8 ruby1.8-dev
2、install rubygem
#http://rubyforge.org/frs/?group_id=126&release_id=20667
wget http://rubyforge.org/frs/download.php/34638/rubygems-1.1.0.tgz
tar zxfv rubygems-1.1.0.tgz
cd rubygems-1.1.0
sudo ruby setup.rb
提示：
RubyGems installed the following executables:
/usr/bin/gem1.8
運行：gem1.8 update –system
3、install Rails and dependencies
sudo gem1.8 install rails –include-dependencies
4、intall Mongrel
sudo apt-get install build-essential
sudo gem1.8 install mongrel –include-dependencies
5、測試
rails 版本：
rails -v
Rails 2.0.2
建立測試應用：
rails cookbook
cd cookbook
./script/server
打開http://localhost:3000/即可看到首頁
注：
1、我在安裝時，運行sudo ruby setup.rb時出現如下錯誤：
./lib/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- rdoc/rdoc (LoadError)
from ./lib/rubygems/custom_require.rb:27:in `require'
from setup.rb:48
解決方法如下：sudo apt-get install -f rdoc
2、在運行./script/server時出現如下錯誤：

from ./script/server:3
出現此錯誤的原因是沒有安裝了libopenssl-ruby 的緣故
kokko@kokko-laptop:~/cookbook$ sudo apt-cache search libopenssl-ruby
libopenssl-ruby - OpenSSL interface for Ruby
libopenssl-ruby1.9 - OpenSSL interface for Ruby 1.9
ruby1.8 - Interpreter of object-oriented scripting language Ruby 1.8
libopenssl-ruby1.8 - OpenSSL interface for Ruby 1.8
這裡使用的是ruby1.8，運行 sudo apt-get install libopenssl-ruby1.8 即可。
