更新NSSM中的Python窗口服务

Question

我使用非吸吮服务管理器(NSSM)为python脚本创建了窗口服务。如果我必须对python .Do做一些更改，我只需要在NSSM启动的指定路径上替换更新过的python，还是也需要更新服务？如果服务需要更新，我如何才能做到？

Answer 1

我删除并重新创建服务(作为localadmin)：

sc.exe stop <servicename>
sc.exe delete <servicename>

您还可以使用nssm.exe：

nssm.exe stop <servicename>
nssm.exe remove <servicename>

随函附上一个powershell脚本，用于将python脚本设置为服务，您必须以localadmin的形式运行它：

    <#
    .SYNOPSIS
        Installing a python script as a service under windows
    .DESCRIPTION
        install a recent python https://www.python.org/ftp/python/3.10.1/python-3.10.1-amd64.exe
        add python to system path
        add a python venv to use (python.exe -m venv <directory to install vens on aka c:\\python\\venvs>)
        set $appexe (must have full path to the venv version), $name and $port
        You also need nssm.exe in the current directory see https://nssm.cc/download and https://nssm.cc/usage
    #>
    $pythonexe = "c:\\dist\\venvs\\gitlab-mobj-board\\Scripts\\python"
    $appexe = (Get-Command .\main.py).Source
    $name = "GitlabBoard"
    $pwd = (pwd).Path
    $port = 8000
    $ip = '0.0.0.0'
    write-host "pythonexe:$pythonexe"
    write-host "appexe:$appexe"
    write-host "name:$name"
    write-host "ip:$ip - port:$port"
    write-host "pwd:$pwd"
    $nssmexe = (Get-Command .\nssm.exe).Path
    $command = '"$nssmexe" install "$name" "$pythonexe" "$appexe" --ip=$ip --port=$port'
    iex "& $command"
    $command = '"$nssmexe" set "$name" AppDirectory "$pwd"'
    iex "& $command"
    $command = '"$nssmexe" set "$name" Start SERVICE_AUTO_START'
    iex "& $command"

    write-host "#start service: sc.exe start $name or Start-Service $name"
    write-host "#stop service: sc.exe stop $name or Stop-Service $name"
    write-host "#delete service: sc.exe delete $name"

下面是运行脚本的输出：

.\create-service.ps1
pythonexe:c:\\dist\\venvs\\gitlab-mobj-board\\Scripts\\python
appexe:C:\dist\work\gitlab-mobj-board\main.py
name:GitlabBoard
ip:0.0.0.0 - port:8000
pwd:C:\dist\work\gitlab-mobj-board
Service "GitlabBoard" installed successfully!
Set parameter "AppDirectory" for service "GitlabBoard".
Set parameter "Start" for service "GitlabBoard".
#start service: sc.exe start GitlabBoard or Start-Service GitlabBoard
#stop service: sc.exe stop GitlabBoard or Stop-Service GitlabBoard
#delete service: sc.exe delete GitlabBoard


.\nssm.exe dump gitlabboard
C:\dist\work\gitlab-mobj-board\nssm.exe install GitlabBoard c:\\dist\\venvs\\gitlab-mobj-board\\Scripts\\python
C:\dist\work\gitlab-mobj-board\nssm.exe set GitlabBoard AppParameters "C:\dist\work\gitlab-mobj-board\main.py --ip=0.0.0.0 --port=8000"
C:\dist\work\gitlab-mobj-board\nssm.exe set GitlabBoard AppDirectory C:\dist\work\gitlab-mobj-board
C:\dist\work\gitlab-mobj-board\nssm.exe set GitlabBoard AppExit Default Restart
C:\dist\work\gitlab-mobj-board\nssm.exe set GitlabBoard DisplayName GitlabBoard
C:\dist\work\gitlab-mobj-board\nssm.exe set GitlabBoard ObjectName LocalSystem
C:\dist\work\gitlab-mobj-board\nssm.exe set GitlabBoard Start SERVICE_AUTO_START
C:\dist\work\gitlab-mobj-board\nssm.exe set GitlabBoard Type SERVICE_WIN32_OWN_PROCESS


sc.exe query gitlabboard

SERVICE_NAME: gitlabboard
        TYPE               : 10  WIN32_OWN_PROCESS
        STATE              : 1  STOPPED
        WIN32_EXIT_CODE    : 1077  (0x435)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0

sc.exe start gitlabboard

SERVICE_NAME: gitlabboard
        TYPE               : 10  WIN32_OWN_PROCESS
        STATE              : 2  START_PENDING
                                (NOT_STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x7d0
        PID                : 21304
        FLAGS

然后我可以去http://localhost:8000，董事会在那里，它会自动启动:-)
