How to host Python 3.7 flask application on Windows Server? - iis

Question

As wfastcgi module is not compatible with Python 3.7, What is the best way to host a python flask application on a Windows Server?

Answer 1

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/
after installing python download the wfastcgi:
pip install wfastcgi
run the command prompt as administrator and run this command.
wfastcgi-enable
run this command to enable wfastcgi.
below is my flask example:
app.py:
from flask import Flask
app = Flask(__name__)
#app.route("/")
def hello():
return "Hello from FastCGI via IIS!"
if __name__ == "__main__":
app.run()
after creating an application to run it use below command:
python app.py
now enable the cgi feature of iis:
now 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”
add below value:
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
request is mapped to:” checkbox is unchecked:
Click “Yes” here:
now go back and again select the server name and select fast CGI setting from the middle pane.
Double click it, then click the “…” for the Environment Variables
collection to launch the EnvironmentVariables Collection Editor:
Set the PYTHONPATH variable:
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):
Click OK and browse to your site:
Note: Do not forget to assign the iusr and iis_iusrs user permission to the flask site folder and python folder.
