安裝使用railscasts（Rails3）

railscasts.com是著名的Rails視頻播客網站，大概每周出一期節目。從2007年3月份至今已經出了270多集，作者Ryan Bates (rbates on Twitter and ryanb on GitHub)持之不懈的工作著實讓人欽佩。我也是陸陸續續看過一些，今日再次光顧railscasts.com網站，發現已經改版，令人欣喜的是其About介紹頁裡也提供了源代碼的鏈接，細看時發現已經升級到Rails3了，一時手癢決定安裝測試下。下面是安裝測試過程：

1、前提

RVM、Ruby1.9.2已經安裝。由於我的虛擬機在早前就已經安裝了Rails3的環境，此處也就略去了。需要的同學可搜索相關文章。

2、下載：使用git工具

代碼倉庫地址：https://github.com/ryanb/railscasts

$ cd projects

$ git clone https://github.com/ryanb/railscasts.git

3、安裝

3.1 生成配置文件，執行"script/setup"。

3.2 安裝項目依賴gem包：

首先安裝bundler，然後使用bundler自動安裝其它依賴包。

1. Ubuntu@ip-10-48-111-136:~/projects/railscasts$ gem install bundler
2. Successfully installed bundler-1.0.15
3. 1 gem installed

4、配置

主要是修改config/database.yml文件中的數據庫用戶名與口令。

5、運行

獨立測試運行：rails s，然後通過浏覽器訪問：http://<IP>:3000。正式使用時可在Apache2或nginx下通過passenger來部署運行。
