Installing Ruby 1.8.6 from Source on Ubuntu
Installing Ruby from source is my preferred method, although in Ubuntu Feisty you can supposedly install it with apt-get install ruby
now. Here’s the essential packages needed to get a source build working right though and the process I just went through:
sudo apt-get install build-essential
sudo apt-get install libreadline-dev
sudo apt-get install libz-dev (this is necessary for RubyGems to install - amongst other things)
wget ftp://ftp.ruby-lang.org/pub/ruby/ruby-1.8.6.tar.gz
tar xzvf ruby-1.8.6.tar.gz
cd ruby-1.8.6
./configure
make
make install
And to install RubyGems..
wget http://rubyforge.org/frs/download.php/17190/rubygems-0.9.2.tgz
tar xzvf rubygems-0.9.2.tgz
cd rubygems-0.9.2
ruby setup.rb

一、创建View/login
在View/login下创建login.html.erb、index.html.erb、loginFail.html.erb
login.html.erb代码如下：
<h1>Welcome to login!</h1>
<% form_tag do %>
& ......
Prepare
1. Download 'OCI 1.x.x.rb' (it's VERY important - execution MUST be *.rb)
2. Download 'oci8lib.so'
Install
1. Copy 'OCI8.rb' to .../ruby/lib/ruby/site_ruby/1.8/DBD/OCI8
2. Copy 'oci8.rb' to .../ruby/lib/ruby/site_ruby/1.8

ruby中单引号和双引号的意义有所不同，双引号包围的字符作变量替换，单引号包围的变量不做替换
也可以使用 %q 和 %Q 来生成字符串对象。%q 相当于单引号，%Q相当于双引号。
举例如下：
irb(main):010:0> "show trsult: #{1*3}"
=> "show trsult: 3"
irb(main):011:0> 'show trsult: #{1*3}'
=> "show trs ......
