ruby_on_rails_2.3.x_安装_手记
周末看书，总想试验一把，可总不能跑到公司去吧~
所以，还得在win下安装一下ruby on rails
基本上按照这个步骤参考为http://rubyonrails.org/download
?
#1 安装ruby
1.8.7
?
#2 安装gem（好像1.9之后不用此步骤了）
1.8.5（公司用的1.3.7）
结果gem的1.8.5版本和rails2.3.8不兼容，下一篇写写gem的事情
?
#3 安装rails
2.3.8
?

测试安装成功否：
D:\>rails -v
Rails 2.3.8
?
其他的包也大致安装吧。

#4 创建一个helloapp
1）装mysql数据库
?
2）生成一个database
mysql> create database hello;
?
3）安装mysql的gem包
D:\>gem install mysql
?
4）生成一个rails app
D:\workruby>rails helloapp

5）配置rails连接数据库
config/database.yml文件
此处为了简单测试，把test和production都配置成了一个，实际的项目应该分开~
?
development:
? adapter: mysql
? database: hello
? pool: 5
? timeout: 5000
? username: root
? password: fantaxy
? host: localhost
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
? adapter: mysql
? database: hello
? pool: 5
? timeout: 5000
? username: root
? password: fantaxy
? host: localhost
production:
? adapter: mysql
? database: hello
? pool: 5
? timeout: 5000
? username: root
? password: fantaxy
? host: localhost
?
6）写ActionPack
#I 在app/controllers目录下新建一个文件hello_controller.rb
class HelloController < ApplicationController
? def index
??? @name = "fantaxy"
??? @now = Time.new
? end
end
?
#II 在app/views目录下新建文件夹hello
#III 在app/views/hello下新建一个view文件index.html.erb
<html>
<head>
? <title>hello</title>
</head>
<body>
<p>Hello <%= @name %></p>
<p>It's now <%= @now.to_s(:db) %></p>
</body>
</html>
?
7）启动server
D:\workruby\helloapp>ruby script\server
=> Booting WEBrick
=> Rails 2.3.8 application starting on http://0.0.0.0:3000
?
8）观察结果
浏览器输入：http://localhost:3000
看见rails的欢迎界面。
可以点击 About your application’s environment 连接看下自己主机的环境
如果有错误，看下后台，比如没有安装mysql的gem包等，会有提示
?
浏览器输入：http://localhost:3000/hello
看见结果：
Hello fantaxy
It's now 2011-07-02 22:35:24

先到此吧。记得找个自己喜欢的ide比较方便。
