Php error chmod operation not permitted

php error chmod operation not permitted

Queries related to “laravel PHP Warning: chmod(): Operation not permitted” · chmod(): Operation not permitted laravel · laravel chmod(): Operation. You got this error because your user is not the owner of /root folder. So you can't change the permission of your folder other than the root. An account can only chmod a file/folder that it is the owner of. You are right. But I have never encountered this as a problem. Is it an error.

Warning: chmod(): Operation not permitted in.

Postby barbaricht » 01. May 2014 20:34

when ever i access a local website i get this error message below in the browser viewpoint:
Warning: chmod(): Operation not permitted in /opt/lampp/htdocs/hottubsandportablespas/content/classes/class.ddm_view.php on line 687

My first thought was file permissions. So i tried changing the owner php error chmod operation not permitted "class.ddm_view.php" file and it's parent folder to "daemon": apache uses "daemon" for its user and group. And i changed the rights of course to rw for user and group. I also tried "nobody", and "root" but the error messages persist.

the "php_error_log" show the same error message:
PHP Warning: chmod(): Operation not permitted in /opt/lampp/htdocs/hottubsandportablespas/content/classes/class.ddm_view.php on essbase error 1042003 687



also on a side note. I attempted just to turn off the php errors. I course I know that turning off php errors will not fix the issue.
in the php.ini file i explicitly turn off display_errors and display_startup_errors but the error message still appears?

thank you for your help

PHP chmod(): Operation not permitted #3172

Still does not work, what we did so far:

  • install ubuntu
  • install a lamp stack
  • creating a virtualserver pointing to a windows-directory, wich resides on drive f (no, var/www or other wsl-directories are NOT an option, since we need to modify / create ecc files directly from windows)
  • installed Joomla
  • tried to install addons or other stuff
  • get a delete not permitted error, found out that it is due to a chmod operation performed before unlinking files within the joomla-core
  • mounted the f-drive wia drvfs with metadata enabled (mounted correctly, i've checked it)
  • tried to install joomla inside the directory directly from wsl (downloaded and unzipped with wget / unzip from the command line)
  • still does not work.
  • tried to install it to var/www/subdir, from there it works, but we cannnot create files directly from windows, since they are invisible to wsl / ubuntu

chmod

(PHP 4, PHP 5, PHP 7, PHP 8)

chmod — Changes file mode

Description

chmod(string, int): bool

Parameters

Path to the file.

Note that is not automatically assumed to be an octal value, so to ensure the expected operation, you need to prefix with a zero (0). Strings such as "g+w" will not work properly.

The parameter consists of three octal number components specifying access restrictions for the owner, the user group in which the owner is in, and to everybody else in this order. One component can be computed by adding up the needed permissions for that target user base. Number 1 means that you grant execute rights, number 2 means that you make the file writeable, number 4 means that you make the file readable. Add up these numbers jib, rfcthdthf cups client-error-not-possible specify needed rights. You can also read more about modes on Unix systems with 'man 1 chmod' and 'man 2 chmod'.

Return Values

Returns on success or on failure.

Errors/Exceptions

Upon failure, an is emitted.

Notes

Note:

The current user is the user under which PHP runs. It is probably not the same user application defined object error excel use for normal shell or FTP access. The mode can be changed only by user who owns the file on most php error chmod operation not permitted.

Note: This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.

chmod(): Operation not permitted - which user should be moodledata owner?

This discussion has php error chmod operation not permitted locked so you can no longer reply to it.

Hi all, I've been seeing these messages popping up for me occasionally and I think I've tracked down the cause. The full error is:

PHP Warning:  chmod(): Operation not permitted in /var/./lib/filestorage/file_storage.php on line 2194, referer: http://./course/delete.php?id=103

Looking at the code, that line performs a chmod on trash files: https://github.com/moodle/moodle/blob/master/lib/filestorage/file_storage.php#L2194

Our Moodledata directory is set to root:apache permissions with  0660 on the files. But even though the apache user is allowed to write the files, because it is not the owner, it's not allowed to chmod the files.

I'm thinking now the proper ownership on the moodledata directory be apache:apache, What are people's thoughts?

If that's the apache owner on your server then, yes, it's apache:apache. If the machine isn't shared you could just chmod -R 0777 your moodledata.

It should be possible to have root oops a system error has occurred restarting the owner of the moodledata directory, provided that you give the apache-user full write permissions in moodledata. What does show? In your case it should print something like (X means don't care).

> But even though the apache user is allowed to write the files, because it is not the owner, it's not allowed to chrome c runtime error the files.

A bit of a confusion there - your apache-user and apache-group both are called apache!

Anyway, could the problem a) missing x in moodledata, I mean instead of ? Or, not right?

Hi Visvanath, 

Good note about differentianting between apache-user and apache-group.

We've been running with it set to root:apache-group for a number of years, the moodledata folder itself has permissions drwxrws--- 

Config.php has $CFG->directorypermissions = 02770;

I just did test though, and on my system, CentOS 7, group write permissions on a file do not let you chmod it. An account can only chmod a file/folder that it is the owner of. 

This would explain all the historical reports of chmod() operation not permitted, because unless the actual apache/web server user is the owner of the files in the moodledata folder, it will not be allowed to run chmod on the files and the errors will be generated.

And actually looking at the recommendations for file system permissions in the docs: https://docs.moodle.org/31/en/Security_recommendations#Most_secure.2Fparanoid_file_permissions

It does state it should be owned by apache-user and group set to apache-group. Looks like I've been running it incorrectly for a while. Atleast now I know! smile

1. moodledata directory and all of its contents (and subdirectories, includes sessions):

owner: apache user (apache, httpd, www-data, whatever; see above) group: apache group (apache, httpd, www-data, whatever; see above) permissions: 700 on directories, 600 on files

2. moodle directory and all of its contents and subdirectories (including config.php):

owner: root group: root permissions: 755 on directories, php error chmod operation not permitted, 644 on files.

If you allow local logins for regular users, then 2. should be:

owner: root group: apache group (apache, httpd, www-data, whatever; see above) permissions: 750 on directories, 640 on files.

In my opinion Moodle does allow a number of combinations for the owner, group and permissions of the moodledata directory and its contents. mp160 error 22 ru us limit the discussion to moodledata/, leave moodle/ out.) In fact I have Moodle instances running where the owner of moodledata/ is not the apache-user.

You are right. But I have never encountered this as a problem, php error chmod operation not permitted. Is it an error or just a warning? Do you have any idea why Moodle needs to change the permissions of files/directories within moodledata/ _after_ they have been created? php error chmod operation not permitted mapservermng file load error mu online php error chmod operation not permitted

> Is it an error or just a warning? Do you have any idea why Moodle needs to change the permissions of files/directories within moodledata/ _after_ they have been created?

It states PHP Warning, php error chmod operation not permitted, and it looks to be in the "deleted_file_cleanup" function. You can see the code here: https://github.com/moodle/moodle/blob/master/lib/filestorage/file_storage.php#L2194

I'm not quite php error chmod operation not permitted why that piece of code changes permissions on file it's deleting, but it's been there since before 2010 and that's as far back as I can go in the Github history. Seems to have been in place for Moodle 2.0, not sure if earlier.

PHP chmod( ):Operation not permitted, safe_mode deprecation involved?

I'm struggling a bit to grasp the concept of from PHP as the course I'm currently taking is a bit outdated and involves safe_mode. It states that as safe_mode is turned off, the restrictions to modify permissions with to a file when the owner is not the same as the one executing the command are removed. I'm working with PHP 5.5.9 in conjuncture with XAMPP, I've verified that the flags are turned off (just in case), but can't seem to get it working. As I execute the following PHP script:

I receive the following output :

My permissions for the file are the following

And I've executed to confirm that the my webserver is operating under the user "daemon" .

As I change the file ownership to daemon:

Everything works, I do not understand why as I had understood that with safe_mode turned off, file ownership would mean nothing, php error chmod operation not permitted, instead file permissions were the way to handle access.
