Apache2的配置，允许一个子域指向一个机器：端口

我自己的域名，“peterlee.com.cn”，我在我的域名控制面板添加一条A记录：Apache2的配置，允许一个子域指向一个机器：端口

RR     Destination IP TTL 
rs.peterlee.com.cn 10.50.10.75  1 hour

我有一个回报率（Ruby on Rails的）项目上10.50.10.75:9051运行，这意味着用户可以通过http://10.50.10.75:9051

我想让用户通过http://rs.peterlee.com.cn参观访问我的RoR应用程序，所以我增加了以下虚拟主机文件/网站：

<VirtualHost *:80> 
    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 

    <IfModule mod_rewrite.c> 
     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] 
    </IfModule> 

</VirtualHost>

使网站和重新启动的Apache2后，我试图http://rs.peterlee.com.cn，它给了我500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.

感谢。

我发现下面的警告在/var/log/apache2/error.log：

[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.

所以我启用以下模块：

sudo a2enmod proxy proxy_balancer proxy_http

重新启动的Apache2后，它的工作！

无论如何。

BTW：

passenger start -a 127.0.0.1 -p 9051 -e production -d

：我使用客运启动服务
