Question

我试图在网络机器上的端口上运行一个非常简单的烧瓶应用程序。我当前的服务器代码如下所示：

123.123.123.123

说我网络上的机器的IP是5000，我想在端口HTTP上运行我的应用程序。我希望能够在浏览器中导航或向123.123.123.123:5000/my_route发出简单的JSON请求并获得500 Internal Server响应。

我试图关注mod_wsgi Flask documentation但未成功。在使用如下指令编辑httpd.conf后，我收到Listen 5000 NameVirtualHost *:5000 <VirtualHost *:5000> ServerName gcr_app WSGIDaemonProcess gcr_app user=apache threads=5 WSGIScriptAlias / /var/www/gcr_app/gcr_app.wsgi <Directory /var/www/gcr_app> WSGIProcessGroup gcr_app WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory> </VirtualHost>错误：

httpd

并重新启动$ /usr/sbin/httpd -v Server version: Apache/2.2.15 (Unix) Server built: Feb 4 2016 08:22:15服务。

我在这里做错了什么？其他信息：

Answer 1

感谢所有评论此问题的人。事实证明，我在运行Flask时使用的Python版本和mod_wsgi的Python版本存在问题。由于我使用的是RHEL 6.7，mod_wsgi已经安装了Python 2.7，而我使用Python 3.4编写了我的应用程序。这意味着mod_wsgi无法导入我正在使用的模块。

除此之外，我还没有正确导入我的Flask应用。我在我的.wsgi文件中有这个：

import my_app as application

而不是：

from my_app import app as application

将一些Python代码更改为2.7兼容并修复我的.wsgi文件后，我能够在我想要的端口上运行Flask应用程序。

如果使用我的Python 3.4版本的mod_wsgi安装pip来运行使用Python 3.4的Flask应用程序，我将更新此答案。

可以在特定端口上运行带有mod_wsgi的Flask应用程序吗？
