使用 mod_proxy 時出現許多 404 URLH時間__H噸米l_html

我想做的事

使所有http://cloud.example.com/>顯示為<http://webmail.example.com/cloud/

• http://cloud.example.com：目標網站
• http://webmail.example.com：使用 mod_proxy 執行 apache2 的網站，作為反向代理（但不僅限於，還有 webmail）。
• http://webmail.example.com/cloud>：我希望<http://cloud.example.com出現的 URL。

我是如何嘗試做到的

<VirtualHost  *:80>

 ServerName webmail.example.com
 DocumentRoot /var/www/roundcubemail-1.1.4
 Loglevel debug
 ErrorLog /var/log/apache2/roundcube.error
 # %t  : Time 
 # %a  : client ip 
 # %f  : filename
 # %T  : processing time 
 # %s  : status
 # %>s : Final status
 LogFormat "%t %a %{Referer}i -> %U%q, matches %f, %s>%>s(served in %{ms}T µs)" custom
 # was "combined"
 CustomLog /var/log/apache2/roundcube.access custom     

 ProxyPass  "/cloud/" "http://cloud.example.com/"
 ProxyPassReverse "/cloud/" "http://cloud.example.com/"

 # The ProxyRequests directive should usually be set off when using ProxyPass.
 # src:https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#proxypass
 ProxyRequests off

 # https://httpd.apache.org/docs/current/mod/mod_proxy.html#proxypreservehost  
 # This option should normally be turned Off.
 ProxyPreserveHost off

</VirtualHost>

日誌的第一行顯示請求“/cloud/”路徑成功從代理網站檢索資源，但所有後續資源都不是從雲伺服器獲取，而是從網路郵件伺服器本身獲取。

我該如何處理？

我啟用了 proxy_html。

正如@HBrijn 所建議的那樣，我添加了

 ProxyPass "/core/" "http://cloud.algerian-radio.dz/core/"
 ProxyPassReverse "/core/" "http://cloud.algerian-radio.dz/core/"

但是隨後伺服器收到了對 /index.php/apps/files/ 的請求，所以我也添加了它

 ProxyPass  "/index.php/apps/files/" "http://cloud.algerian-radio.dz/apps/file\
s/"
 ProxyPassReverse "/index.php/apps/files/" "http://cloud.algerian-radio.dz/app\
s/files/"

擺脫了所有 404 錯誤，但仍然無法讓 owncloud 工作。

http://webmail.example.com/cloud>重定向到<http://webmail.example.com/index.php/apps/files/顯示這個不錯的錯誤：

Fatal error: Class 'OCP\User' not found in /usr/local/nginx/html/owncloud/apps/files/index.php on line 33

編輯：固定！，owncloud 方面需要一些額外的配置，即trusted_proxies和overwritewebroot。
