將jupyterlab註冊爲windows服務

簡介

新公司都是在windows辦公，嘗試了將好用的jupyterlab註冊成服務，成功後記錄一下

步驟

安裝依賴pywin32

在要做成notebook根目錄的目錄下創建install_service.py文件

import win32serviceutil
import win32service
import win32event
import servicemanager
import win32process
from win32process import CreateProcess
import os
import socket
import traceback
import getpass
import time

work_dir = os.path.abspath(os.path.dirname(__file__))
jupyterlab_path = r'E:\python38\Scripts\jupyter-lab.exe'


class Service(win32serviceutil.ServiceFramework):
    _svc_name_ = "JupyterLab"
    _svc_display_name_ = "JupyterLab Service"
    _svc_description_ = "JupyterLab Service"

    def __init__(self, *args):
        os.chdir(work_dir)
        super().__init__(*args)
        self.hWaitStop = win32event.CreateEvent(None,0,0,None)
        socket.setdefaulttimeout(60)

    def SvcStop(self):
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
        rc = win32event.WaitForSingleObject(self.handle[0], 1000)
        if not rc == win32event.WAIT_OBJECT_0:
            win32process.TerminateProcess(self.handle[0],0)
        self.ReportServiceStatus(win32service.SERVICE_STOPPED)
        win32event.setEvent(self.hWaiStop)

    def SvcDoRun(self):
        servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,
                                      servicemanager.PYS_SERVICE_STARTED,
                                      (self._svc_name_, ''))
        self.handle = CreateProcess(jupyterlab_path, '', None, None, 0,
                  win32process.CREATE_NO_WINDOW, None, None,
                  win32process.STARTUPINFO())
        rc = win32event.WaitForSingleObject(self.handle[0], 2)
        
        self.running = True
        # time.sleep(100)
        while self.running:
            rc = win32event.WaitForSingleObject(self.handle[0], 1000)
            if rc == win32event.WAIT_OBJECT_0 or rc == win32event.WAIT_FAILED:
                self.running = False
            time.sleep(3)



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

• 記得修改文件中的jupyterlab_path爲你本機實際地址

在有管理員權限的powershell中執行

python install_service.py --username ".\你windows用戶名" --password "你windows密碼" --startup=auto install

• 如果要刪除、更新就將install 改爲remove、delete
• 一定要停止服務之後再刪除，不然需要重啓電腦纔可以重新安裝

打開任務管理器，在服務面板啓動。或者重啓電腦也行。
