允许子域指向计算机的Apache2配置：端口
我拥有域名“peterlee.com.cn”，我在我的域控制面板中添加了一个A Record：
RR Destination IP TTL rs.peterlee.com.cn 10.50.10.75 1 hour 我有一个运行于10.50.10.75:9051的RoR（Ruby on Rails）项目，这意味着用户可以通过http://10.50.10.75:9051访问我的RoR应用程序
我想让用户通过http://rs.peterlee.com.cn访问它，所以我添加了以下VirtualHost文件/站点：
ServerName rs.peterlee.com.cn DocumentRoot /usr/website/myapp/current/public PassengerEnabled off ProxyPass / http://127.0.0.1:9051/ ProxyPassReverse / http://127.0.0.1:9051/ RackEnv production RailsEnv production RewriteEngine On # Redirect all requests to the maintenance page if present RewriteCond %{REQUEST_URI} !\.(css|gif|jpg|png)$ RewriteCond %{DOCUMENT_ROOT}/system/maintenance.html -f RewriteCond %{SCRIPT_FILENAME} !maintenance.html RewriteRule ^.*$ /system/maintenance.html [L]
启用站点并重新启动Apache2后，我尝试了http://rs.peterlee.com.cn ，它给了我500个内部服务器错误：
Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. Apache/2.2.22 (Ubuntu) Server at rs.peterlee.com.cn Port 80
谢谢。
彼得
我在/var/log/apache2/error.log发现了以下警告：
[Thu Jul 19 10:22:20 2012] [warn] proxy: No protocol handler was valid for the URL /. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.

If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.
所以我启用了以下模块：
sudo a2enmod proxy proxy_balancer proxy_http
重启Apache2后，它运行了！
不管怎么说，还是要谢谢你。
顺便说一句：我使用Passenger启动服务：
passenger start -a 127.0.0.1 -p 9051 -e production -d
