Can Python Scripts Run as Windows Services?

Can Python Scripts be Executed as Windows Services?

To manage a set of programs sharing database objects, you're considering Python and Django for a service that provides higher-level operations. However, you need to determine whether Python programs can run as Windows services for optional support.

Running Python as a Windows Service

Yes, it is possible to execute Python programs as Windows services. This involves utilizing the pythoncom libraries included in ActivePython or PyWin32. Below is a basic skeleton for a simple service:

import win32serviceutil
import win32service
import win32event
import servicemanager
import socket

class AppServerSvc(win32serviceutil.ServiceFramework):
    ...  # class definition omitted for brevity

if __name__ == '__main__':
    win32serviceutil.HandleCommandLine(AppServerSvc)

The service's main functionality should be placed in the main() method, typically involving an infinite loop that can be terminated by checking a flag set in the SvcStop method.

Windows Service Awareness and Management

Upon registering the service, Windows becomes aware of its existence. To manage the service, use the following utilities:

• Service Manager (services.msc): View, start, stop, and manage installed services.
• Command Prompt: Use the net command with flags like start, stop, and status to control the service.
• PowerShell: Employ cmdlets like Get-Service, Start-Service, and Stop-Service to manage services.

Equivalent to /etc/init.d on Windows

On Windows, the Functionality provided by /etc/init.d on Linux is handled through:

• Service Control Manager API: Allows programmatic control of services.
• System Configuration Utility: Used to configure services that run at system startup.
