How Do I Deploy a Python Web Application in Windows Server?


Scott Campbell

Deploying a Python web application on a Windows Server can be a daunting task, but with the right steps and tools, it can be done smoothly. In this tutorial, we will walk you through the process of deploying your Python web application on a Windows Server. Let’s get started!

Step 1: Prepare your Windows Server

Before we begin the deployment process, make sure you have a Windows Server up and running. Ensure that you have installed Python on your server and set up the necessary environment variables. You can download Python from the official website and follow their installation instructions.

Step 2: Install and Configure Web Server

In order to serve your Python web application, you need to install a web server. One popular option is Internet Information Services (IIS). To install IIS on your Windows Server, follow these steps:

  1. Open the Server Manager.
  2. Select Add Roles and Features.
  3. In the wizard, select Web Server (IIS).
  4. Choose the components you want to install (such as ASP.NET) and click Next.
  5. Review the installation summary and click Install.

Note: Make sure to enable CGI feature in IIS if your Python web application requires it.

Step 3: Configure IIS for Python Web Applications

To configure IIS for serving Python web applications, follow these steps:

  1. Open the Internet Information Services (IIS) Manager.
  2. Select your server from the Connections pane.
  3. Double-click on the Handler Mappings feature.
  4. In the right-hand pane, click Add Module Mapping.
  5. Enter the following details:
    • Request path: *.py
    • Module: FastCgiModule
    • Executable: C:\Python\python.exe (replace with your Python installation path)
    • Name: Python FastCGI
  6. Click OK to save the module mapping.

Step 4: Deploy Your Python Web Application

You are now ready to deploy your Python web application on the Windows Server. Here’s how you can do it:

  1. Create a new folder in your web server’s directory to host your application files.
  2. In this folder, copy all the files and directories of your Python web application.
  3. Create a new file named “” (or any name you prefer) in the root of your web application folder. This file will act as an entry point for your application.
  4. #
    from myapp import app
    if __name__ == "__main__":

    In the above example, we assume that your Flask application object is named “app”. Modify it according to your application setup.

    Note: If you are using a different web framework like Django, adjust the code accordingly.

  5. Open the Internet Information Services (IIS) Manager.
  6. Double-click on the Sites feature.
  7. Right-click on the default website or create a new website if needed.
  8. Select Add Application.
  9. In the Alias field, enter a name for your application (e.g., “myapp”).
  10. In the Physical path field, browse and select the folder where you copied your application files.
  11. Click OK to save the application settings.


You have successfully deployed your Python web application on a Windows Server. Now, you can access your application by visiting your server’s IP address or domain name in a web browser. Make sure that you have any necessary firewall rules or port forwarding set up to allow access to your web server from external networks.

I hope this tutorial has been helpful in guiding you through the deployment process. Happy coding!
