将 PM2 安装为 Windows 服务 [已关闭]

Question

我在 Windows 上使用 PM2 来启动 Nodejs 应用程序。
我希望 PM2 在 Windows 启动（引导、重新启动等）时也启动。

我尝试使用 pm2-windows-service 将 PM2 设置为 Windows 服务，但没有成功。

如何将 PM2 设置为服务？

Answer 1

使用 pm2-service-install 来变量 Pm2 进行服务 将以下脚本（ps1）放入源代码文件夹中

# Deploys application as an app within a PM2 service
# Run from root of Node application

param(
    [string] $Pm2Home = $env:PM2_HOME,
    [string] $AppStart = "app.js"
)
    
$ErrorActionPreference = "Stop"

function Install-Node-Modules
{
    Write-Host "Running npm install"
    & "npm" i
}

function Create-Pm2-Home
{
    Write-Host "Attempting to create $Pm2Home and give FullControl to LOCAL SERVICE"
    New-Item -ItemType Directory -Force -Path $Pm2Home

    $rule = New-Object System.Security.AccessControl.FileSystemAccessRule(
        "LOCAL SERVICE", "FullControl", "ContainerInherit, ObjectInherit",
        "None", "Allow")

    try {
      $acl = Get-Acl -Path $Pm2Home -ErrorAction Stop
        $acl.SetAccessRule($rule)
        Set-Acl -Path $Pm2Home -AclObject $acl -ErrorAction Stop
        Write-Host "Successfully set FullControl permissions on $Pm2Home"
    } catch {
        throw "$Pm2Home : Failed to set permissions. Details : $_"
    }
}

function Install-Pm2-Service
{
    $UserPath = $env:userprofile
    Write-Host "Installing pm2"
    & "npm" i "pm2@latest" "-g"
    Write-Host "Installing pm2-windows-service npm module"

    # Create wrapper log file, otherwise it won't start
    $wrapperLogPath = "$(npm config get prefix)\node_modules\pm2-windows-service\src\daemon\pm2.wrapper.log"
    
    if (Test-Path $wrapperLogPath) {
        Write-Debug "PM2 service wrapper log file already exists"
    } else {
        Out-File $wrapperLogPath -Encoding utf8
    }

    param([string] $ConfigPath, [string] $CmdPath)

    $configContent = @"

[Environment]::SetEnvironmentVariable("PM2_HOME", $env:PM2_HOME, "Machine")
[Environment]::SetEnvironmentVariable("PM2_SERVICE_SCRIPTS", $env:PM2_SERVICE_SCRIPTS, "Machine")

& Install-Node-Modules
& Create-Pm2-Home
& Create-Pm2-Service-Config -ConfigPath $env:PM2_SERVICE_SCRIPTS -CmdPath $AppStart
& Install-Pm2-Service
& Change-Pm2-Service-Account

执行以下命令。

.\install.ps1 -Pm2Home "C:\Users\Admin\.pm2" -AppStart "C:\SourceCode\app.js"

In it:
C:\Users\Admin\.pm2  : .pm2 path
C:\SourceCode\app.js : App.js path

在提示中输入以下内容。

? Perform environment setup (recommended)? Yes 
? Set PM2_HOME? Yes 
? PM2_HOME value (this path should be accessible to the service user and should not contain any “user-context” variables [e.g. %APPDATA%]): c:\etc\.pm2\ 
? Set PM2_SERVICE_SCRIPTS (the list of start-up scripts for pm2)? No 
? Set PM2_SERVICE_PM2_DIR (the location of the global pm2 to use with the service)
? [recommended] Yes ? Specify the directory containing the pm2 version to be used by the service C:\USERS\<USER>\APPDATA\ROAMING\NPM\node_modules\pm2\index.js
