无法从终端运行fastcgi脚本。这个脚本应该由Apache执行。通常，您在Apache配置文件中的
ScriptAlias
指令中配置了它。

通常，您应该使用
mod\u fastcgi
和类似的配置：

<VirtualHost *:8091>
  ServerName helloworld.local
  DocumentRoot /home/fe/work/flipflop
  FastCgiServer /home/fe/work/flipflop/run.py
  ScriptAlias / /home/fe/work/flipflop/run.py
    <Location />
      Options none
    </Location>
</VirtualHost>


ServerName helloworld.local
文档根/主/fe/工作/触发器
FastCgiServer/home/fe/work/flipflop/run.py
ScriptAlias//home/fe/work/flipflop/run.py
选项无
因此，它将使您的脚本以FastCgi的形式运行，但我不熟悉触发器，无法使其工作

但如果您不限于
flipflop
，您可以使用
uwsgi
运行应用程序，
mod_wsgi
使用
Apache
运行应用程序（请参阅中的更多详细信息），或者使用
Flask Script
runserver
命令在调试服务器中运行应用程序（请参见《第一件事》中的示例，看起来您已经有一些应用程序在端口5000上运行/侦听。 您可能希望使用
sudosockstat | grep5000
查找哪个，然后配置Apache，或者使用
localhost:5000
终止进程/服务

其次，您的虚拟主机似乎未被考虑/未完全配置 
from flask import Flask
