Скрипт python как служба windows

This answer is plagiarizer from several sources on StackOverflow — most of them above, but I’ve forgotten the others — sorry. It’s simple and scripts run «as is». For releases you test you script, then copy it to the server and Stop/Start the associated service. And it should work for all scripting languages (Python, Perl, node.js), plus batch scripts such as GitBash, PowerShell, even old DOS bat scripts.
pyGlue is the glue that sits between Windows Services and your script.

'''
A script to create a Windows Service, which, when started, will run an executable with the specified parameters.
Optionally, you can also specify a startup directory

To use this script you MUST define (in class Service)
1. A name for your service (short - preferably no spaces)
2. A display name for your service (the name visibile in Windows Services)
3. A description for your service (long details visible when you inspect the service in Windows Services)
4. The full path of the executable (usually C:/Python38/python.exe or C:WINDOWS/System32/WindowsPowerShell/v1.0/powershell.exe
5. The script which Python or PowerShell will run(or specify None if your executable is standalone - in which case you don't need pyGlue)
6. The startup directory (or specify None)
7. Any parameters for your script (or for your executable if you have no script)

NOTE: This does not make a portable script.
The associated '_svc_name.exe' in the dist folder will only work if the executable,
(and any optional startup directory) actually exist in those locations on the target system

Usage: 'pyGlue.exe [options] install|update|remove|start [...]|stop|restart [...]|debug [...]'
Options for 'install' and 'update' commands only:
        --username domain\\username : The Username the service is to run under
        --password password : The password for the username
        --startup [manual|auto|disabled|delayed] : How the service starts, default = manual
        --interactive : Allow the service to interact with the desktop.
        --perfmonini file: .ini file to use for registering performance monitor data
        --perfmondll file: .dll file to use when querying the service for performance data, default = perfmondata.dll
Options for 'start' and 'stop' commands only:
        --wait seconds: Wait for the service to actually start or stop.
                If you specify --wait with the 'stop' option, the service and all dependent services will be stopped,
                each waiting the specified period.

Now there’s a bit of editing and you don’t want all your services called ‘pyGlue’. So there’s a script (build.sh) to plug in the bits and create a customized ‘pyGlue’ and create an ‘.exe’. It is this ‘.exe’ which gets installed as a Windows Service. Once installed you can set it to run automatically.

#!/bin/sh
# This script build a Windows Service that will install/start/stop/remove a service that runs a script
# That is, executes Python to run a Python script, or PowerShell to run a PowerShell script, etc

if [ $# -lt 6 ]; then
        echo "Usage: build.sh Name Display Description Executable Script StartupDir [Params]..."
        exit 0
fi

name=$1
display=$2
desc=$3
exe=$4
script=$5
startDir=$6
shift; shift; shift; shift; shift; shift
params=
while [ $# -gt 0 ]; do
        if [ "${params}" != "" ]; then
                params="${params}, "
        fi
        params="${params}'$1'"
        shift
done

cat pyGlue.py | sed -e "s/pyGlue/${name}/g" | \
        sed -e "/_svc_name_ =/s?=.*?= '${name}'?" | \
        sed -e "/_svc_display_name_ =/s?=.*?= '${display}'?" | \
        sed -e "/_svc_description_ =/s?=.*?= '${desc}'?" | \
        sed -e "/service_exe =/s?=.*?= '$exe'?" | \
        sed -e "/service_script =/s?=.*?= '$script'?" | \
        sed -e "/service_params =/s?=.*?= [${params}]?" | \
        sed -e "/service_startDir =/s?=.*?= '${startDir}'?" > ${name}.py

cxfreeze ${name}.py --include-modules=win32timezone

Installation — copy the ‘.exe’ the server and the script to the specified folder. Run the ‘.exe’, as Administrator, with the ‘install’ option. Open Windows Services, as Adminstrator, and start you service. For upgrade, just copy the new version of the script and Stop/Start the service.

Now every server is different — different installations of Python, different folder structures. I maintain a folder for every server, with a copy of pyGlue.py and build.sh. And I create a ‘serverBuild.sh’ script for rebuilding all the service on that server.

# A script to build all the script based Services on this PC
sh build.sh AutoCode 'AutoCode Medical Documents' 'Autocode Medical Documents to SNOMED_CT and AIHW codes' C:/Python38/python.exe autocode.py C:/Users/russell/Documents/autocoding -S -T

Introduction

If you want to run a Python script as a Windows service you can use the Non-Sucking Service Manager to create the service.
This application allows you to easily create a service using any executable or batch script that gets
treated as a proper Windows service that you can manage Windows services by running services.msc or by going to the Services tab from the Task Manager.

The most common use case for running a Python script as a service is to ensure an application is always run
and starts running when you log in.
For example, if you have a web application that you want to stay running whenever the computer is up.
I have used this method to run Flask applications and other utilities.

Setup

Download nssm and extract nssm.exe.
NSSM is a single file nssm.exe that does not need any special installation.

For convenience, you may want to place the file inside a directory in your %PATH%
environment variable, otherwise you will need to execute it using the full path.
To learn how to set environment variables in Windows, check out my tutorial
Set Environment Variables in Windows.

You will also need Python installed.

I recommend creating a virtual environment. I usually create at least one virtual environment in
my user’s home directory in a directory named venv. Then I can be sure Python is available in C:\Users\<my_user>\venv\Scripts\python.exe.
To learn how to setup a Python virtual environment, check out my tutorial
Python Virtual Environments Tutorial.

IMPORTANT: When running nssm commands, tou need to run the Command Prompt as an Adminstrator. Right click on Command Prompt and choose Run as Administrator.

Create Windows service to run Python script

To create a custom service, you simply need to run nssm install and tell it the name of your new service
and what program you want to run. In this case we are calling Python from the virtual environment
and running a Python script from my user’s home directory.

nssm.exe install "MyCustomService" "C:\Users\nanodano\venv\Scripts\python.exe" "C:\Users\nanodano\myscript.py"

You should see a message that says something like:

Service "MyCustomService" installed successfully!

It will default to have Startup type: Automatic. This means it will start automatically when the computer restarts.

Start and stop your custom service

You can use the normal Services manager services.msc or you can use NSSM from the Command Prompt.
You can start and stop the service like this:

nssm.exe start MyCustomService
nssm.exe stop MyCustomService

Delete the service

If you no longer want the service you can remove it with the following command:

nssm.exe remove "MyCustomService"

Conclusion

After reading this, you should understand how to create your own custom Windows service to run a Python script using NSSM.
You should understand how to create the service and remove it as well as how to start, stop, and restart it.
You should understand how to run a specific Python interpreter to run a Python script.
