php - 从 PHP 运行脚本

Question

我有一个关于PHP和Linux系统交互的问题。

我想从网页启动Steam，该页面的地址是

http://site.eu/cp/user/services/21/steaminstall

以及我运行命令所在网页的内部路径

/var/www/wwwuser/data/www/site.eu/panel.php?(here goes $_POST[''] data)

Steam 客户端是

/var/www/wwwuser/data/Steam/SteamInstall

问题是，我知道如何访问这个脚本，我也可以执行简单的

echo "Script is Runing"

但是当我的操作涉及到这段代码时

#!/bin/bash
wget -P /var/www/aftersoft/data/Servers/Steam/ http://media.steampowered.com/client/steamcmd_linux.tar.gz &&
tar xvfz /var/www/aftersoft/data/Servers/Steam/steamcmd_linux.tar.gz -C /var/www/aftersoft/data/Servers/Steam/ &&
sh /var/www/aftersoft/data/Servers/Steam/steamcmd.sh +login anonymous +quit &&
rm /var/www/aftersoft/data/Servers/Steam/steamcmd_linux.tar.gz &&
echo "Steam Installation and Update Completed"

如果我从网页运行它，它不会执行任何操作，但当我尝试在 SSH 用户下运行它时它会起作用(与具有写入此文件夹权限的 apache 用户相同)

所以我的问题是，我做错了什么？

更新: 我运行脚本的 php 代码是

if($path[2] === 'steaminstall')
{
    $InstallSteam = exec('/var/www/aftersoft/data/Servers/Steam/SteamInstall', $Output, $Error);
    if($Error === 0)
    {
      $Status = $DB->SteamStatus($_SESSION['username']);
      if($Status)
      {
         header('Location: /cp/'.$_SESSION['username'].'/services/');
      }
      else
      {
         $Smarty->assign('InstallStatus', 'Database Error Occured');
         $Smarty->display('steaminstall.tpl');
      }
    }
    if($Error === 2)
    {
       $Smarty->assign('InstallStatus', $Output);
       $Smarty->display('steaminstall.tpl');
    }
}

这是我的数据库查询功能

public function SteamStatus($Username)
{
    $Status = '1';
    $Statement = $this->DBConnection->prepare("UPDATE account set steaminstalled = ? where username = ?");
    $Statement->bindParam(1, $Status);
    $Statement->bindParam(2, $Username);
    $IStatus = $Statement->execute();
    if($IStatus)
    {
       return true;
    }
    else
    {
       return false;
    }
}

问题解决了，你只需要指定脚本的直接路径(就好像你不指定，脚本本身不知道在哪里下载和解压)

最终的 bash 脚本(PHP 部分完全没问题):

#!/bin/bash
wget -P /var/www/aftersoft/data/Servers/Steam/ http://media.steampowered.com/client/steamcmd_linux.tar.gz &&
tar xvfz /var/www/aftersoft/data/Servers/Steam/steamcmd_linux.tar.gz -C /var/www/aftersoft/data/Servers/Steam/ &&
sh /var/www/aftersoft/data/Servers/Steam/steamcmd.sh +login anonymous +quit &&
rm /var/www/aftersoft/data/Servers/Steam/steamcmd_linux.tar.gz &&
echo "Steam Installation and Update Completed"
