我對Wt和cgi的東西很新。我想要做的是用C++編寫一個Web應用程序。這可能是由於在重量庫：如何在我的本地apache服務器中顯示我的Wt應用程序？
顯然有兩種模式：HTTP和FastCGI。前者直接使用：我編譯我的代碼並運行bin。這啓動了某種Web服務器（我的詞彙可能不準確，因爲我是這個域中的一個大白菜）並輸出服務器的地址和端口。在我最喜歡的瀏覽器中鍵入所有內容將顯示我用C++編寫的網頁。
我對後者有一個很大的問題，這非常煩人，因爲這是在託管遠程服務器上部署軟件的唯一方法。
要部署測試Web服務器，我使用了Wt庫中的hello示例，並通過定義cmake變量EXAMPLES_CONNECTOR = wtfcgi將其與wtfcgi關聯。
之後，我安裝了apache2並進行了設置。我做了以下內容：
我安裝了以下的Ubuntu軟件包：
libapache2-mod-fastcgi
apache2
apache2-bin
apache2-data
apache2-utils
然後，
- 啓用的mod_fastcgi的Apache與a2enmod
- 修改配置文件fastcgi.conf是這樣的：
<IfModule mod_fastcgi.c>; AddHandler fastcgi-script .wt FastCgiIpcDir /var/lib/apache2/fastcgi FastCgiConfig -idle-timeout 100 -maxClassProcesses 1 -initial-env WT_APP_ROOT=/tmp FastCgiServer /var/www/wt/hello.wt </IfModule>
<Directory /var/www/wt/> Allow from all Options +ExecCGI </Directory>
複製我的重量示例代碼爲/var/www/wt/hello.wt
的文件夾啓用網站和重裝阿帕奇
a2ensite wt service apache2 reload
然後，在這之後，/var/log/apache2/error.log給我
[Fri Jun 16 22:52:30.176846 2017] [core:notice] [pid 1676:tid 139808785006080] AH00094: Command line: '/usr/sbin/apache2'

在那之後，我跟着這個網頁給出的建議是：
http://redmine.webtoolkit.eu/projects/wt/wiki/Fastcgi_on_apache
例如，我自己創建了/ var/run/wt並將其所有者更改爲www-data。然後我得到這個日誌：
AH00112: Warning: DocumentRoot [/var/www/html] does not exist

然後看起來很好。但是，當我現在在我的Firefox瀏覽器上顯示地址127.0.1.1時，我仍然可以看到默認的apache2網頁。爲什麼我沒有看到hello示例？我該如何解決？我是否必須編寫一個調用hello.wt的特殊html頁面？這是如何運作的？
看起來好像有些東西已經開始，但不能繼續運行。我在哪裏可以找到那些日誌？
在此先感謝！
