PHP file_put_contents返回'Permission Denied'（由于SELinux设置）

Question

I know this is a common issue but I haven't been able to single out the problem for my specific use case, so bear with me.

I have a simple PHP script send_id which simply sends an ID number and saves it to a TXT file on my RHEL server running Apache 2.4.6 with PHP 5.4.

The error message: Warning: file_put_contents(/var/www/html/id.txt): failed to open stream: Permission denied in /var/www/html/send_id.php on line 6 '1' written to server

The PHP script itself:

<?php
$id=$_GET['id'];
$stringData = "$id";
$file = file_put_contents('/var/www/html/id.txt', $stringData.PHP_EOL , FILE_APPEND |LOCK_EX);
echo "'$stringData' written to server";
?>

chmodding to 777 didn't do anything. Additionally, I checked to see ownership rights and noticed that the id.txt file is owned by the root user at both user/group level, and PHP is being run at root level.

Anyone have any suggestions? If its any help, this seems to have happened after a yum update

Answer 1

I resolved this issue by simply running chcon -Rt httpd_sys_content_rw_t on the directory where my troubled PHP script lived in.

Additional note

ls -alZ *

The -Z switch will work with most utilities to show SELinux security contexts
