为什么 apache 在系统根目录而不是项目目录中查找文件，我得到像 FileNotFound 这样的错误
Why apache find files on system root directory instead of project directory, I got error like FileNotFound
Apache 在我的 /var/www/web_app_video_synopsis 项目目录中找不到文件，但在系统根目录 '/'
中找到了 files/directories
当我提示 URL http://<server IP:5000>
Apache 获取错误cat /var/log/apache2/error.log
