我在将文件从 PHP 上传到 Centos 7.0 Apache 服务器时遇到问题

PHP 代码

  <html>
<head>
  <title>Upload your files</title>
</head>
<body>
  <form enctype="multipart/form-data" action="index.php" method="POST">
    <p>Upload your file</p>
    <input type="file" name="uploaded_file"></input><br />
    <input type="submit" value="Upload"></input>
  </form>
</body>
</html>
<?PHP
  if(!empty($_FILES['uploaded_file']))
  {
    $path = "/var/www/html/";
    $path = $path . basename( $_FILES['uploaded_file']['name']);
    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $path)) {
      echo "The file ".  basename( $_FILES['uploaded_file']['name']). 
      " has been uploaded";
    } else{
        echo "There was an error uploading the file, please try again!";
    }
  }
?>

请注意，file_uploads 在 php.ini 中是开启的

文件夹“/var/www/html/”的权限是0777，它的所有者是apache

我在stackoverflow中尝试了几乎所有的解决方案，

chmod -R 0777 /var/www/html

chown apache /var/www/html

find /var/www/html/ -type f -print0 | xargs -0 chmod -v 777

仍然文件上传失败，并在 HTTPD error_log 中出现此错误

[Tue Mar 19 10:34:21.257969 2019] [:error] [pid 27446] [client 172.20.20.41:61798] PHP Warning:  move_uploaded_file(/var/www/html/Scan.pdf): failed to open stream: Permission denied in /var/www/html/index.php on line 23, referer: http://10.104.25.70/index.php

输出

ls -l

是

drwxrwxrwx. 3 apache root 34 Mar 18 13:24 html

输出

stat html

是

【问题讨论】：

只是为了确保检查您尝试移动的文件的权限，而不是文件夹本身。

标签： php apache file-upload centos

【解决方案1】：

Selinux需要配置上下文

cd /var/www/html
mkdir upload
chown apache:apache upload
chcon -t httpd_sys_rw_content_t upload
ls -Z /var/www/html
