我对Wt和cgi的东西很新。我想要做的是用C++编写一个Web应用程序。这可能是由于在重量库：如何在我的本地apache服务器中显示我的Wt应用程序？
显然有两种模式：HTTP和FastCGI。前者直接使用：我编译我的代码并运行bin。这启动了某种Web服务器（我的词汇可能不准确，因为我是这个域中的一个大白菜）并输出服务器的地址和端口。在我最喜欢的浏览器中键入所有内容将显示我用C++编写的网页。
我对后者有一个很大的问题，这非常烦人，因为这是在托管远程服务器上部署软件的唯一方法。
要部署测试Web服务器，我使用了Wt库中的hello示例，并通过定义cmake变量EXAMPLES_CONNECTOR = wtfcgi将其与wtfcgi关联。
之后，我安装了apache2并进行了设置。我做了以下内容：
我安装了以下的Ubuntu软件包：
libapache2-mod-fastcgi
apache2
apache2-bin
apache2-data
apache2-utils
然后，
- 启用的mod_fastcgi的Apache与a2enmod
- 修改配置文件fastcgi.conf是这样的：
<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>
复制我的重量示例代码为/var/www/wt/hello.wt
的文件夹启用网站和重装阿帕奇
a2ensite wt service apache2 reload
然后，在这之后，/var/log/apache2/error.log给我
[Fri Jun 16 22:52:30.176846 2017] [core:notice] [pid 1676:tid 139808785006080] AH00094: Command line: '/usr/sbin/apache2'

在那之后，我跟着这个网页给出的建议是：
http://redmine.webtoolkit.eu/projects/wt/wiki/Fastcgi_on_apache
例如，我自己创建了/ var/run/wt并将其所有者更改为www-data。然后我得到这个日志：
AH00112: Warning: DocumentRoot [/var/www/html] does not exist

然后看起来很好。但是，当我现在在我的Firefox浏览器上显示地址127.0.1.1时，我仍然可以看到默认的apache2网页。为什么我没有看到hello示例？我该如何解决？我是否必须编写一个调用hello.wt的特殊html页面？这是如何运作的？
看起来好像有些东西已经开始，但不能继续运行。我在哪里可以找到那些日志？
在此先感谢！
