以root權限進行以下步驟，

======從這裡開始======

1.安裝所需的debian套件

# aptitude install ruby ruby-dev rubygems build-essential libopenssl-ruby apache2-mpm-prefork apache2-prefork-dev

2.以rubygems安裝ruby套件

# gem install rake
# gem install rails

3.建立程式link

# ln -s /var/lib/gems/1.8/bin/rake /usr/local/bin/rake
# ln -s /var/lib/gems/1.8/bin/rails /usr/local/bin/rails

4.建立rails應用程式

# cd /var/www
# rails test_ap

5.安裝Phusion Passenger

# gem install passenger

6.安裝apache2的passenger模組

# cd /var/lib/gems/1.8/gems/passenger-2.0.3/bin

此目錄下的檔案若未標示成可執行，先變更檔案屬性
# chmod +x passenger-*

# ./passenger-install-apache2-module

7.建立模組的定義檔案

# vim /etc/apache2/mods-available/passenger.load

輸入以下內容，
LoadModule passenger_module /var/lib/gems/1.8/gems/passenger-2.0.3/ext/apache2/mod_passenger.so

8.載入passenger模組

# a2enmod passenger

若無法執行a2enmod，可自行建立link
# ln -s /etc/apache2/mods-available/passenger.load /etc/apache2/mods-enabled/passenger.load

9.編寫apache2的設定檔

# vim /etc/apache2/sites-available/test_ap

輸入以下內容，
PassengerRoot /var/lib/gems/1.8/gems/passenger-2.0.3
PassengerRuby /usr/bin/ruby1.8

NameVirtualHost *

ServerName www.yourhost.com
DocumentRoot /somewhere/public


10.變更預設web server

# cd /etc/apache2/sites-enabled
# rm 000-default
# ln -s /etc/apache2/sites-available/test_ap 001-test_ap

11.重新啟動apache2

# /etc/init.d/apache2 restart

正常來說，此時連到apache2 server會看到rails的歡迎畫面。

======到這裡結束======

由於有一些gem在安裝時會進行complie，若沒有先安裝ruby-dev和build-essential的話，可以享有額外的一些安裝體驗……
