安装使用railscasts（Rails3）

railscasts.com是著名的Rails视频播客网站，大概每周出一期节目。从2007年3月份至今已经出了270多集，作者Ryan Bates (rbates on Twitter and ryanb on GitHub)持之不懈的工作着实让人钦佩。我也是陆陆续续看过一些，今日再次光顾railscasts.com网站，发现已经改版，令人欣喜的是其About介绍页里也提供了源代码的链接，细看时发现已经升级到Rails3了，一时手痒决定安装测试下。下面是安装测试过程：

1、前提

RVM、Ruby1.9.2已经安装。由于我的虚拟机在早前就已经安装了Rails3的环境，此处也就略去了。需要的同学可搜索相关文章。

2、下载：使用git工具

代码仓库地址：https://github.com/ryanb/railscasts

$ cd projects

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

3、安装

3.1 生成配置文件，执行"script/setup"。

3.2 安装项目依赖gem包：

首先安装bundler，然后使用bundler自动安装其它依赖包。

ubuntu@ip-10-48-111-136:~/projects/railscasts$ gem install bundlerSuccessfully installed bundler-1.0.151 gem installed

以下是完整的安装日志：

4、配置

主要是修改config/database.yml文件中的数据库用户名与口令。

5、运行

独立测试运行：rails s，然后通过浏览器访问：http://<IP>:3000。正式使用时可在Apache2或nginx下通过passenger来部署运行。
