Apache-2.2

頁面不會直接在域下結束

  • April 16, 2013

我正在嘗試在 Ubuntu 伺服器上使用 Apache 和 tomcat 設置一個 java 頁面。我遇到的問題是該頁面最終不在域下，而是在域上的虛擬文件夾中，就像這樣。

example.com/example/

如果我輸入 example.com，則找不到該頁面。如何讓頁面顯示在 example.com 下？

這是我的站點可用配置

<VirtualHost *:8080>
       ServerName example.com
       DocumentRoot /www/example

       <Directory /www/example/>
               AllowOverride All
               Order allow,deny
               allow from all
       </Directory>

       JkMount /* worker1
</VirtualHost>

這是workers.properties

worker.list=worker1
worker.worker1.type=ajp13
worker.worker1.host=localhost
worker.worker1.port=8009

   # After setting JkStripSession to "On", mod_jk will
   # strip all ";jsessionid=..." from request URLs it
   # does *not* forward to a backend.
   # This is useful, if all links in a webapp use
   # URLencoded session IDs and parts of the static

   # IMPORTANT: Mounts and virtual hosts
   # If you are using VirtualHost elements, you
   # - can put mounts only used in some virtual host into its VirtualHost element 
   # - can copy all global mounts to it using "JkMountCopy On" inside the VirtualHost
   # - can copy all global mounts to all virtual hosts by putting
   #   "JkMountCopy All" into the global server
   # Since: 1.2.26

我通過在我的網頁目錄中創建一個名為 ROOT 的目錄並將所有內容移入其中來解決這個問題。不是一個完美的解決方案，但它有效。

只需將文件從 /www/example 移動到 /www 並更改 DocumentRoot 和 Directory 指令以匹配。
