php - move_uploaded_file 失败但权限似乎正确

Question

我正在将我的网站从共享主机迁移到 VPS。在我的 VPS 上进行测试时，我发现突然间我无法再通过网络表单上传文件了。

错误:警告:move_uploaded_file(/uploads/logoklein.jpg):无法打开流:/var/www/vhosts/denkproducties.nl/httpdocs/denkproducties/upload.php 中第 26 行警告中没有这样的文件或目录警告:move_uploaded_file (): 无法在第 26 行的/var/www/vhosts/denkproducties.nl/httpdocs/denkproducties/upload.php 中将“/tmp/php01nhmx”移动到“/uploads/logoklein.jpg”

SO 上有很多关于此的问题，它们几乎都涉及正确设置权限。我将 TMP 和上传目录修改为 0777(不寒而栗)，但无济于事。我知道 0777 不是明智之举，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，我认为问题一定出在服务器上。我想也许网络服务器正在以“无人”身份运行，所以它无法访问 tmp 文件夹。我跑了:

ps aux | grpe httpd

这告诉我:

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

顺便说一句，我的服务器正在运行 fCGI。

为了完整起见，我制作了一个带有网络表单的小型上传脚本:

$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 :(. }

我在这里错过了什么？

Louis Huppenbauer 在评论中对我的类似问题给出了正确的答案。

使用相对路径是行不通的，它需要一个完整路径。尝试将/uploads/更改为主机的完整目录，例如:D:\InetPub\Vhosts\website.com\website2.com\uploads\
