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

 

D:\>gem install rails -v 2.3.8
Fetching: rake-0.9.2.gem (100%)
Fetching: activesupport-2.3.8.gem (100%)

Fetching: actionpack-2.3.8.gem (100%)

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

      create  log/production.log
      create  log/development.log
      create  log/test.log

 

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。
