Apache 作为具有子域的 Tomcat 的代理

Question

尽管我在 SO 上发现了一些类似的报告，但没有任何建议可以解决我的问题。所以我决定自己提出一个问题。

我在 Ubuntu 上的 Tomcat 实例上将 Confluence(和 Jira)作为 WAR 运行。该应用程序可通过 http://localhost:8080/confluence 访问.我想将 apache 配置为代理以允许通过 http://confluence.<servername>.de 进行公共(public)访问.按照 https://confluence.atlassian.com/display/DOC/Using+Apache+with+mod_proxy#UsingApachewithmod_proxy-complex 上的说明进行操作我做了以下步骤:

• 附加属性proxyName="confluence.<servername>.de"和 proxyPort="80"到 /var/lib/tomcat7/conf/server.xml 中的连接器元素。
• 在/etc/apache2/sites-enabled/confluence.conf 中定义了一个虚拟主机

confluence.conf 包含以下内容:

<VirtualHost *:80>
  ServerName confluence.<servername>.de

  ProxyRequests Off
  ProxyPreserveHost On

  <Proxy *>
    Order deny,allow
    Allow from all
  </Proxy>

  ProxyPass / http://localhost:8080/confluence
  ProxyPassReverse / http://localhost:8080/confluence

  ProxyHTMLURLMap / /confluence/

  <Location />
    Order allow,deny
    Allow from all
  </Location>
</VirtualHost>

使用此配置我无法调用 http://localhost:8080/confluence由于这个 (wget) 输出:

--2014-12-23 08:38:13--  http://localhost:8080/confluence
Resolving localhost (localhost)... ::1, 127.0.0.1

HTTP request sent, awaiting response... 404 Not Found
2014-12-23 08:38:13 ERROR 404: Not Found.

如果我删除属性 proxyName 和 proxyPort，则可以进行此访问。但是，通过 http://confluence.<servername>.de 调用仍然会产生错误。 Apache 日志的输出表明 URL 重写已损坏:

我错过了什么吗？顺便说一句，如果我以 URL http://<servername>.de/confluence 的方式调整虚拟主机配置用作代理一切正常。

如有任何建议，我们将不胜感激。

我个人的偏好是在子文件夹中部署应用程序并像这样设置代理:

ProxyPass "/confluence/" "http://localhost:8080/confluence/"
ProxyPassReverse "/confluence/" "http://localhost:8080/confluence/"

不需要 ProxyHTMLURLMap，这可能就是您看到“AH00944:连接 http://localhost:8080/confluenceconfluence/ 到 localhost:8080”的原因

按照您的预期进行设置可能有点棘手，因为您需要机器的完全限定域名为 confluence.servername.de 并且您还需要在本地 DNS 中有一个 A 记录。我支持 Slash 的问题:你能 ping confluence.servername.de 吗？

解决了这个问题后，您可能还想根据需要研究使用这些指令:

ProxyRequests Off
ProxyVia Off
RemoteIPHeader X-Forwarded-For
RequestHeader    unset  Accept-Encoding
ProxyHTMLEnable On
ProxyHTMLExtended On
<Proxy *>
    Require all granted
</Proxy>
