我安装了 Apache 和 Tomcat7 的两个实例。一个在装有 Mountain Lion 的 Macbook Pro 上，另一个在装有 Ubuntu Server 12.10 的 Mac 上的 VirtualBox VM 中。两者具有相同的 VirtualHost 配置和 server.xml 配置。
在我的 Mac 上一切正常，但在 Ubuntu VM 上我收到“文件不存在”错误。
当我将 LogLevel 设置为 'debug' 时，日志输出看起来几乎相同。
有没有其他地方我可以看看为什么请求没有被代理到 Tomcat？
这是我的配置文件。

好的，两个想法。首先，在您的 Apache 配置中，为什么您有 3 个 URL 的 ProxyPass 设置，这些设置似乎都设置为存在
/portal/？如果可能的话，我建议将其简化为以下内容：
我还添加了这一点
mod_rewrite以确保添加了尾部斜杠：另外，因为
mod_proxy我这样做：这将全部加起来像这样的 Apache 虚拟主机配置。我还建议回滚
proxy.conf到您的默认设置。将所有需要的设置放在 VirtualHost 文件中，如下所示，这样你就不必做任何事情，但要确保配置文件在设置之间浮动，并且你不会将配置调整散布到所有类型的文件中：在连接 Java Web 服务和 Apache 配置的世界时，这种设置对我来说总是非常有用。
