ruby on rails win下安装发现新的技术ruby on rails，关于他一些介绍就不说了，我说下今天的我的安装过程！
首先是下载
http://rubyforge.org/projects/rubyinstaller/
我弄的是最新的！然后安装，跟安装其他软件一样
本地安装没学会，需要下载
gem
http://rubyforge.org/frs/?group_id=126
还要下载一个配套的apache，这个他采用的apache2，所以没有的话就装一个
http://www.neokeen.com/mornlee/="http://rubyforge.org/projects/rubyforapache/"
这个东西也要安装，主要是生成了一个一些东西，有用的就是2个so文件，是给apache加载用的，用来结实这个语言用的，虽然速度不好，稳定不好，但是现在基本能用，等真做服务器的时候在想办法吧，还有就是修改httpd.conf[文件了，跟php的加载差不多！
添加
LoadModule fastcgi_module modules/mod_fastcgi.so
<IfModule mod_fastcgi.c>
AddHandler fastcgi-script .fcgi
</IfModule>
注意so文件的位置
继续添加
AddDefaultCharset utf-8
LoadModule rewrite_module modules/mod_rewrite.so #注意so文件的位置
<VirtualHost *:80>
ServerName 127.0.0.1
DocumentRoot d:/web/demo/public/
ErrorLog d:/web/demo/log/apache.log
<Directory d:/web/demo/public/>
Options ExecCGI FollowSymLinks
AddHandler cgi-script .cgi
AllowOverride all
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
注意d:/web为你的虚拟目录
启动一个cmd
进入安装的ruby目录默认是c:\ruby\bin
输入 C:\ruby\bin>ruby -v
显示 ruby 1.8.2 (2004-12-25) [i386-mswin32]
输入 C:\ruby\bin>gem update
在这步的时候一定要注意代理的问题，如果不能连接网络会有错误提示，我弄了很久才成功，我有代理，我使用了一个代理软件来完成的，有人介绍了一些其他的方法，我没实验成功！我的代理软件的名称是sockscap
显示很多的东西，是让你选择要更新的选相，我选择的是2
输入 C:\ruby\bin>gem install rails
所有都输入 y
显示
C:\ruby\bin>gem install rails
C:\ruby\bin>"c:\ruby\bin\ruby.exe" "c:\ruby\bin\gem" install rails

基本上算是把环境搭建成功了！
建立一个demo，也就是一个测试
在目录c:\ruby\bin下运行下列语句：
输入 rails d:\web\demo 设置目录放置的位置，跟apache设置要统一
显示

create doc/README_FOR_APP
create log/server.log
create log/production.log
create log/development.log
create log/test.log
修改demo应用目录下的相关文件
依据rails习惯约定规则使用命令行(在当前demo应用目录下)
ruby -i.bak -pe 'gsub!("#!/usr/local/bin/ruby", "#!c:/ruby/bin/ruby")' public/dispatch.* script/*
将文件：
public/dispatch.cgi, public/dispatch.rb, public/dispatch.fcgi, script/breakpointer, script/console, script/generate, script/server
的文件开始部分的：
#!/usr/local/bin/ruby
改成:
#!c:/ruby/bin/ruby
一定要修改,否则FastCGI会出错.
重起apache，输入本机ip http://127.0.0.1/
出现页面为
Congratulations, you've put Ruby on Rails!Before you move on, verify that the following conditions have been met:
The log and public directories must be writable to the web server (chmod -R 775 log and chmod -R 775 public). The shebang line in the public/dispatch* files must reference your Ruby installation.
You might need to change it to #!/usr/bin/env ruby or point directly at the installation. Rails on Apache needs to have the cgi handler and mod_rewrite enabled.
Somewhere in your httpd.conf, you should have:
AddHandler cgi-script .cgi
LoadModule rewrite_module libexec/httpd/mod_rewrite.so
AddModule mod_rewrite.c Take the following steps to get started:
Create empty development and test databases for your application.
Recommendation: Use *_development and *_test names, such as basecamp_development and basecamp_test
Warning: Don't point your test database at your development database, it'll destroy the latter on test runs! Edit config/database.yml with your database settings. Create controllers and models using the generator in script/generate
Help: Run the generator with no arguments for documentation See all the tests run by running rake. Develop your Rails application! Setup Apache with FastCGI (and Ruby bindings), if you need better performance Remove the dispatches you don't use (so if you're on FastCGI, delete/move dispatch.rb, dispatch.cgi and gateway.cgi) Trying to setup a default page for Rails using Routes? You'll have to delete this file (public/index.html) to get under way. Then define a new route in config/routes.rb of the form:
map.connect '', :controller => 'wiki/page', :action => 'show', :title => 'Welcome'
Having problems getting up and running? First try debugging it yourself by looking at the log files.
Then try the friendly Rails community on the web or on IRC (FreeNode#rubyonrails).
