Question

我有一个使用shell exec渲染视频文件的wesbite。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高管在其文件夹中都有自己的文件。单独地，它们执行正常，但是当它们同时运行时，第二个用户命令失败。是否有任何解决方案可以让服务器运行多个shell exec调用，或者我是否必须实现像gearrman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
