移动\u上载的\u文件失败，但权限似乎正确

Question

我正在将我的网站从共享主机移动到VPS。当我在VPS上测试时，我注意到突然之间我再也无法通过网络表单上传文件了。

错误：警告：move_uploaded_file（/上传/logoklein.jpg）：未能打开流：在第26行 /var/www/vhosts/denkproducties.nl/httpdocs/denkproducties/upload.php中没有这样的文件或目录警告：move_uploaded_file（）：无法将/tmp/php01nhmx移动到/上传/<##################################################################################################################################################

关于这一点有很多问题，它们几乎都涉及到设置正确的权限。我将TMP和uploads目录都添加到0777（抖动），但没有任何效果。我知道0777不是一件明智的事情，但我想确保这不是这些文件夹的权限问题。

由于唯一改变的是VPS，我想问题一定出在服务器上。我想可能是web服务器以“无人”身份运行，所以它无法访问tmp文件夹。我跑：

ps aux | grpe httpd

这让我明白：

root   27371   0.0  2.3   340860   24726  ?   SNs   12:57   0:00   /usr/sbin/httpd

root   27817   0.0  0.0   103244     824 tty1 S+    13:40   0:00   grep httpd

顺便说一下，我的服务器正在运行fCGI。

为了完整起见，我用一个web表单制作了一个小的上传脚本：

$allowed_filetypes = array('.jpg','.gif','.bmp','.png'); // These will be the types of file that will pass the validation.
   $max_filesize = 1024000; // Maximum filesize in BYTES (currently 1MB).
   $upload_path = '/uploads/'; // The place the files will be uploaded to (currently a 'uploads' directory).


   $filename = $_FILES['userfile']['name']; // Get the name of the file (including file extension).
   $ext = substr($filename, strpos($filename,'.'), strlen($filename)-1); // Get the extension from the filename.

   // Check if the filetype is allowed, if not DIE and inform the user.
   if(!in_array($ext,$allowed_filetypes))
      die('The file you attempted to upload is not allowed.');

   // Now check the filesize, if it is too large then DIE and inform the user.
   if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize)
      die('The file you attempted to upload is too large.');

   // Check if we can upload to the specified path, if not DIE and inform the user.
   //if(!is_writable($upload_path))
   //   die('You cannot upload to '. $upload_path .'the specified directory, please CHMOD it to 777.');

   // Upload the file to your specified path.
   if(move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename)){
         echo 'Your file upload was successful, view the file here'; // It worked.
     } else {
         echo 'There was an error during the file upload.  Please try again.'; // It failed :(.
 }

我错过了什么？

Louis Huppenbauer在评论中对我的类似问题给出了正确的答案。

使用相对路径无效，它需要完整路径。尝试更改/上载/到主机的完整目录，例如：D:\InetPub\Vhosts\website。com\website2。com\上传\
