我的项目做了很久了，可惜没有rails环境支持，迟迟没有上线。最近买了hostmonster的虚拟主机，买它之前据说它是支持ror的，搞了大半天，全是扯淡…还得自己动手。
首先，你要去hostmonster申请SSH，去提交个Ticket就行了，很快的。
首先用ssh登陆服务器，为rails application创建一个工作区，
xx@xx.com [~]# mkdir rails
xx@xx.com [~]# cd rails
xx@xx.com [~]# rails inlocals
xx@xx.com [~]# cd inlocals
接下来，建立一个子域名供这个程序运行。登入cPanel,，点击 ’subdomains’，在第一个文本框中输入’inlocals’点击’Add’即可。
删除inlocals子域名创建的文件夹。将inlocals应用的public目录设为inlocals.xx.com的根根目录。
xx@xx.com [~]# rm -r ~/public_html/inlocals
xx@xx.com [~]# cd ~/public_html/
xx@xx.com [~]# ln -s ~/rails/inlocals/public inlocals
打开inlocals.xx.com可以看到我的Ruby on Rails的欢迎语。接下来将你的代码全部上传到rails/inlocals目录，把rails/inlocals/public /dispatch.cgi的权限设为755，在public目录下新建一个.htaccess文件，内容如下：
   1. # General Apache options
   2. AddHandler fcgid-script .fcgi
   3. AddHandler cgi-script .cgi
   4. Options +FollowSymLinks +ExecCGI
   5.  
   6. # If you don't want Rails to look in certain directories,
   7. # use the following rewrite rules so that Apache won't rewrite certain requests
   8. #
   9. # Example:
  10. #   RewriteCond %{REQUEST_URI} ^/notrails.*
  11. #   RewriteRule .* - [L]
  12.  
  13. # Redirect all requests not available on the filesystem to Rails
  14. # By default the cgi dispatcher is used which is very slow
  15. #
  16. # For better performance replace the dispatcher with the fastcgi one
  17. #
  18. # Example:
  19. #   RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
  20. RewriteEngine On
  21.  
  22. # If your Rails application is accessed via an Alias directive,
  23. # then you MUST also set the RewriteBase in this htaccess file.
  24. #
  25. # Example:
  26. #   Alias /myrailsapp /path/to/myrailsapp/public
  27. #   RewriteBase /myrailsapp
  28.  
  29. RewriteBase /
  30. RewriteRule ^$ index.html [QSA]
  31. RewriteRule ^([^.]+)$ $1.html [QSA]
  32. RewriteCond %{REQUEST_FILENAME} !-d
  33. RewriteCond %{REQUEST_FILENAME} !-f
  34. RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
  35.  
  36. # In case Rails experiences terminal errors
  37. # Instead of displaying this message you can supply a file here which will be rendered instead
  38. #
  39. # Example:
  40. #   ErrorDocument 500 /500.html
  41.  
  42. ErrorDocument 500 "<h2>Application error</h2>Rails application failed to start properly"
打开浏览器，输入http://inlocals.xx.com，over了。
我将我自己的域名www.inlocals.com绑定到inlocals.xx.com,就可以使用www.inlocals.com访问偶的网站了…
注：
忘了一个问题，我打开网站，发现图片和css、js文件显示不正常，由于我的css、js、图片文件都放在特定的目录下，加上RewriteCond %{REQUEST_FILENAME} !-d设置当目录存在时重写规则对该目录无效。这样图片和风格就可以正常显示了。
