Php Web服务器上的Shell Exec

我有一个wesbite，它使用shell exec渲染视频文件。它执行以下php代码：

shell_exec('powershell -File C:\Render\templater.ps1 -v "CC 2017" -m);
shell_exec('powershell -File C:\Render1\templater.ps1 -v "CC 2017" -m);

两个shell执行器的文件夹中都有自己的文件。单独执行时，它们执行良好，但当同时运行时，第二个用户命令失败。是否存在允许服务器运行多个shell exec调用的变通方法，或者我是否必须实现像gearman这样的队列管理器

Templater.ps1代码如下：

Param (
    [string]$v = " ",
    [switch]$ui = $false,
    [switch]$m  = $false,
    [switch]$h  = $false
)

$usage = @'
    Desc:   
        Launches Templater for Adobe After Effects
        from the command line.  A supported version of
        After Effects is required to be installed on this 
        machine for this launcher to work properly.
    Usage:
        .\templater.ps1 -v 'ae_version_string' [-ui] [-m]
    Options:
        -h
        Shows this documentation
        -v | --version 'ae_version_string'
        The version of AE you want to use with Templater, 
        where 'version_string' can be any ofthe following: 
        'CC 2017' 'CC 2015.3' 'CC 2015' 'CC 2014' 'CC' 'CS6' 'CS5.5' 'CS5'
        -ui 
        If specified, Adobe After Effects will launch with its
        graphical user interface
        -m
        If included, this causes AE to launch as a new, seperate,
        process.  This is useful if you want to simultaneously
        execute two or more versioning jobs with Templater.
    Examples:
        Launch without AE user interface

          > .\templater.ps1 -v 'CC 2015'
          > .\templater.ps1 -v 'CS5'


        Launch with AE user interface

          > .\templater.ps1 -v 'CC 2015' -ui
          > .\templater.ps1 -v 'CS5' -ui
        Launch new instance of AE without its user interface
          > .\templater.ps1 -v 'CC 2015' -m

您是否意外地让多个用户使用相同的输入或输出文件运行该命令？这将大错特错。您需要渲染到不同的文件，并且可能来自不同的输入。不，所以当我进行测试时，我同时使用以下两个命令进行测试：shell_exec（'powershell-File C:\render\templater.ps1-v“CC 2017”）；shell_exec（'powershell-文件C:\Render2\templater.ps1-v“CC 2017”）；所以它们是类似的命令，但每个命令都在自己的文件夹中。所以这并不是说他们使用的是相同的文件。php是否允许运行多个shell_exec调用（来自不同用户），前提是他们使用的文件不同？还是所有调用都转到同一个shell_exec？是否确定.ps1文件不同时使用这两个文件？您可能需要编辑问题以添加PS1文件，以便我们为您提供帮助。感谢您迄今为止的帮助。我已经添加了ps1代码。当我同时在命令行上（在不同的shell中）运行上述两个命令时，效果很好，因此我认为这与共享文件无关。
