python.exe-FastCGI进程意外退出 [英] python.exe - The FastCGI process exited unexpectedly

问题描述

我已经在这里和IIS论坛上阅读了有关此问题的所有文章，也将其发布到了Google的第二页上……仍然无法正常工作.

我想在Windows Server 2016上的IIS中运行Flask/Python应用，但我一直收到此错误:

  HTTP错误500.0-内部服务器错误C:\ Program Files \ Python38 \ python.exe-FastCGI进程意外退出详细的错误信息:模块FastCgiModule通知ExecuteRequestHandler处理程序FastCGI-Python错误代码0x00000002 

我设法使其在我的机器上运行(Windows 10)，但在服务器上不起作用.

• IIS 10
• Python 3.8
• wfastcgi 3.0.0

I have read all posts about this issue, here and on IIS forum, got it to the second page on Google too... and still can't get it to work.

I want to run Flask/Python app in IIS on Windows server 2016, but I keep getting this error:

HTTP Error 500.0 - Internal Server Error
C:\Program Files\Python38\python.exe - The FastCGI process exited unexpectedly

Detailed Error Information:
Module     FastCgiModule
Notification       ExecuteRequestHandler
Handler    FastCGI-Python
Error Code     0x00000002

I managed to get it work on my machine (Windows 10), but on server nope.

Environment

• Windows Server 2016
• IIS 10
• Python 3.8
• wfastcgi 3.0.0
• Flask 1.1.1

I tried different versions of Python (3.6, 3.7, 3.8). On my Windows 10 it's running Python 3.7 and it's working fine. I can't use Python 3.4.2, as it was suggested in one of the posts, because Flask runs on 3.5 and higher and apparently wfastcgi works fine with Python 3.7 on my machine.

I granted full permissions to my application pool and to IIS_IUSRS on my web app folder and Python folder.

I have installed Microsoft C++ Build Tools too.

And the configuration of IIS has been shared from my machine to server through "Shared Configuration", so everything is the same. I just adapted some paths in config file.

I tried also running web app on Flask WSGI server for development and it worked fine.

Does anyone has a clue what more I can do? Any advice would be nice.

Thanks :)

解决方案

You could follow the below steps to configure python flask application in iis:

1)First, you need to install the python,wfastcgi, and flask at your server.

You can download the python from below link:

https://www.python.org/downloads/

Note: if possible please use python version above 3.6.

2)after installing python install the wfastcgi. run the command prompt as administrator and run below command:

pip install wfastcgi

wfastcgi-enable

3)below is my flask example:

from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
    return "Hello from FastCGI via IIS!"
if __name__ == "__main__":
    app.run()

4)after creating an application to run it use below command:

python app.py

5)enable the cgi feature of iis:

6)open iis.

right-click on the server name and select add site.

enter the site name physical path and the site binding.

after adding site select the site name and select the handler mapping feature from the middle pane.

Click "Add Module Mapping"

executable path value:

C:\Python37-32\python.exe|C:\Python37-32\Lib\site-packages\wfastcgi.py

Click "Request Restrictions". Make sure "Invoke handler only if the request is mapped to:" checkbox is unchecked:

Click "Yes" here:

7)now go back and select the application setting feature.

click add from the action pane.

Set the PYTHONPATH variable(which is your site folder path):

And the WSGI_HANDLER (my Flask app is named app.py so the value is app.app — if yours is named site.py it would be site.app or similar):

8)Click OK and browse to your site.

Note: Do not forget to assign the iis_iusrs and iusr permission to the site folder and the python folder.
