When I try to create a Python file (.py) in my Django application, I get an error 500. The file is created, and the code isn't the problem. I can create a text file or any other format. It would need to be a Python file because I need it for further steps.
I am using Windows 10 and running the Django application on IIS. Windows, IIS and Django are all up-to-date.
I already tried to add permission to the folder I will edit. I tested around with some other settings but haven't figured out the problem yet. I think it should be something with permission of IIS or Django.
This is my error message:
d:\django\virtualenv0\scripts\python.exe - The FastCGI process exited unexpectedly
Most likely causes:
IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.
IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.
IIS was not able to process configuration for the Web site or application.
The authenticated user does not have permission to use this DLL.
The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.
Things you can try:
Ensure that the NTFS permissions for the web.config file are correct and allow access to the Web server's machine account.
Check the event logs to see if any additional information was logged.
Verify the permissions for the DLL.
Install the .NET Extensibility feature if the request is mapped to a managed handler.

I was able to solve my problem. I switch from IIS to Apache which didnt had any problem with creating a .py file anymore. After that I got an empty models file. The only thing left to do was to add in the absolute path python in the os.system(command).
Now everything works fine.
you need to check some below settings:
1)you enable iis CGI feature.
2)ensure pip and setup tools are fully upgraded:
python -m pip install pip --upgrade && pip install setuptools --upgrade
3)install the virtualenv tool:
pip install virtualenv
4)Activate the virtualenv so all our commands affect this interpreter.
C:\inetpub\wwwroot\mydjangoproject\> venv\scripts\activate
5)Configured the WFast CGI in iis.
6)"d:\django\virtualenv0\" path has iis_iusrs and iusr full control permission.
7)check iis application pool identity which server Django project.
for more detail, you could refer this link.
and please share your web.config file for more detail about the issue.

I have set up a Python flask through IIS. I have set up IIS and wfastcgi. I have verified below -
Install IIS and CGI
Install wfastcgi
Created webconfig file
Configure IIS directories and permissions

What I am missing please help
System:
Windows 10 x64 (enterprise computer with some restrictions)
Apache 2.4 64-bit
Python 3.7.1 64-bit
mod_wsgi (built today from github using python setup.py install)
I am working on getting an Apache server with Python on a Windows machine and I have the server configured correctly in order to get the Hello World! example from mod_wsig documentation working.
If I simply launch C:\Apache24\bin\httpd.exe, this works and I see Hello World at http://localhost:5000/
Then I wanted to get it running as a service, so I call
httpd.exe -k install
In the ApacheMonitor I start the new Apache2.4 service but I get a failed to start error. In the Windows system event log it says Event ID: 7024 with a service specific error: Incorrect function.
When I run httpd.exe -k start -n "Apache2.4" -t it says Syntax OK
What I can't find is any more information about the service error. Nothing populates in the error.log file and I don't know where else to look, and I am asking for any further information on how to diagnose this.
Before I started configuring Apache to use mod_wsgi, launching the service was successful, so this happened after doing that, and I haven't configured anything else at this point.
Go to the Command Prompt move to the apache/bin folder and type
>httpd -t
This will give you more information about the error preventing Apache from start.
I was getting this error after updating my httpd.conf file. The problem was that my final xml tag in httpd.conf was unclosed </directory without the closing >.
This days I was facing the same situation, windows 10, apache24, django app, python3.8, failing to start as service, service events showing error 7024...
So, after a lot of struggling and research, I would like to add my solution even this is an old question.
The solution was to add two environment variables, no in httpd.conf, not in python code/conf but at SO level (windows > environment variables)
PYTHONHOME = c:\your\path\to\installed\python
PYTHONPATH = c:\your\path\to\installed\virtualenv
And magic! apache now works as service and the django app is always available on localhost
I was able to configure the FastCGI service so that whenever the client requests any call it will create only one process and serve all the requests.
This service is working only If the wfastcgi.py file present in python root directory.
If I install that python module (wfastcgi) using pip install wfastcgi, it will go to python(root)/site-packages/wfastcgi/wfastcgi.py file.
If I specify the above path (python(root)/site-packages/wfastcgi/wfastcgi.py) in web.config file, it is not taking it. default IIS/FastCGI error is throwing by saying that...
500 Internal Server error: <handler> scriptProcessor could not be found in <fastCGI> application configuration
We wanted to place this file in the installed directory itself meaning under site-packages.
My question here is how can we specify the site-packages location to the FastCGI service (There are no folder permission errors).
I had a Python Flask website that ran fine when I ran the app pool as my own account. When I tried changing this to a service account (which should have permissions), I get the following error

If I change it back to run as my own account, it works. Any thoughts?
FYI after some tinkering, I changed the app pool to run with Managed Pipeline mode of "Classic" instead of "Integrated" and it worked.
I have an Azure web app with a Flask template. I want it to connect to a SQL database. I made one. I installed pymssql. For testing purposes I added to the views.py in the root folder:
import pymssql
conn = pymssql.connect(server='mydb.database.windows.net', user='mydbnameadmin#mydb', password='secret', database='mydb')
I first tested locally on my kubuntu box. To make sure I was getting a connection, I entered the wrong password, and the server threw an error. I entered it correctly and the error disappeared. Cool. Also the SQL dashboard on the azure portal reported sucessfull connections. So then I pushed my changes (including updating the requirements.txt) to my github repo and it was sucked into my web application. When I tried running the web app, on the index page:
The page cannot be displayed because an internal server error has
occurred.
After turning on and inspecting the detailed logs all I get it:
HTTP Error 500.0 - Internal Server Error
The page cannot be displayed because an internal server error has occurred.

IIS. What's that doing here? I thought MS was trendy and hosted this service on a linux box 0_0
I remove the second line
conn = pymssql.connect(server='mydb.database.windows.net', user='mydbnameadmin#mydb', password='secret', database='mydb')
and the error disappeared. If I run a server locally, which still uses the Azure SQL server, I don't have any issues.
This seems to be the same issue I have:

but they say whether they actually got it working with a SQL database...
what do people think?
Thanks
my requirements.txt
alembic==0.7.7
azure==0.11.1
Flask==0.10.1
Flask-Migrate==1.5.0
Flask-Script==2.0.5
Flask-SQLAlchemy==2.0
futures==3.0.3

pymssql==2.1.1

Werkzeug==0.10.4
wheel==0.24.0
Per my understanding, Azure Web sites are hosted on Windows Server 2012 VM by default, which would not install FreeTDS and also we don't have permission to install it. And the pymssql is based on FreeTDS.
So we can use pyodbc to connect the Azure SQL as a workaround way to handle it in ease.
I was able to successfully connect my Python code to a SQL Database on Azure using the pymssql 2.1 library.
I don't know if this is what is causing the problem but I did include a couple of extra parameters in my connection string... maybe that will help. I specified the driver explicitly and the Encrypt parameter since SSL is always enabled for SQL Azure (I believe)
myConnection = pyodbc.connect('Driver={SQL Server};'
'Server=tcp:1234567.database.windows.net,1433;'
'Database=MyAzureDatabase;'
'Uid=geekgirl#123456;Pwd=abcdef;'
'Encrypt=yes')
If that doesn't work, maybe try adding some error handling around the connect statement to try and get a more specific error message.
Fingers crossed!
I had this problem, but I eventually realized it was because I was using the 64-bit version of Python in Visual Studio, but Azure only supports the 32-bit version.
I was seeing:
DLL load failed: %1 is not a valid Win32 application.
Once I switched to installing and using the 32-bit version I was able to use Flask and pyodbc with no problems.
