我正在尝试将 apache 配置为充当某些子域的代理。我几乎已经配置好了，但是有一个问题。
使用此配置，我设法让 www.mywebsite.com 正常服务（无代理/默认 apache 配置），同时通过代理为 localhost 端口 8080 提供 subdomain.mywebsite.com。我遇到的问题是请求到 index.html 以外的文件获取代理错误 502。
ServerAdmin [email protected]
ServerName subdomain.mywebsite.com
DocumentRoot "/opt/www/subdomain"
<Proxy *>
Order allow,deny
Allow from all
</Proxy>
ProxyPass / http://127.0.0.1:8080
ProxyPassReverse / http://127.0.0.1:8080
如何配置 apache 以通过代理服务所有文件？
我刚才建立了一个站点在端口 8080 上工作，并复制配置，仅更改根目录和端口，我希望在端口 8082 上提供另一个站点，但它失败了：Error 102 (net::ERR_CONNECTION_REFUSED): The server refused the connection.
这是所有相关的配置文件，如果有遗漏的，我可以发布更多。

我在 openvz 虚拟主机上，因此此处报告的内存使用情况top来自整台机器。s 占用了我的sshd大部分可用内存 - 为什么有这么多？我需要它们吗？
互联网上是否有资源，我可以在其中下载 ubuntu 服务器安装所需的单个文件？
/etc/grub.d/00_header在这种情况下，我需要Ubuntu 服务器 12.04的干净版本。有时我想为特定的 linux 版本获取文件的干净版本。
除了在其他地方再次安装 ubuntu 并从那里复制文件之外，我将如何获取我需要的文件？
我做了apt-get upgrade一个新版本的 grub 替换有问题的版本的希望，并得到了这个错误。据我了解，更新后的 grub 应该替换旧的（我选择使用 /etc/defualt/grub 的包维护者版本），因此解析后出现的错误与新的 grub 版本有关，而不是我的本地版本版本。那是对的吗？

我收到 Mailer Daemon 消息说某些电子邮件发送失败。我的域是itaccess.org由 Google 应用程序管理的。有什么方法可以确定谁在从我的域发送电子邮件，以及他们是如何发送电子邮件的，而无需我为他们创建帐户？
