I am using XAMPP and apache as webserver. I have permission problems with a website of mine that requires write access to a temporary folder in the project folder /htdocs/myProject/tmp
It think my problem is that my site runs on my localhost and I copied the project with my regular desktop user into the htdocs folder. Apache seems to lack write permissions.
My question is now: How do I found out which user group apache belongs to in order to make that group owner of the folder? That should fix my permission problem, shouldn't?
As far as I understand, the Apache (Webserver) has an own user called "www-data". Maybe an already answered question on SO has a solution, which you can use.
The used command relies on a linux-based system and that you navigated in a terminal to a directory, where /htdocs is located.
This command in the answer of the link below allows you as a humanoid user to write and work in this specified directory.
You add www-data (Apache) to use this directory, too.
New files of that chown'ed directory will 'inherit' the owners.

I am setting up a multimedia server on Debian 8.
I installed both Plex and Owncloud. I have set up /var/media as my Owncloud default folder. I decided to create a folder Library at the root of Owncloud. So the folder path is:
/var/media/admin/files/Library
I changed the permissions of media with:
chmod 770 -R /var/media
On top of that, all the files in /var/media are owned by www-data:www-data.
In order to make Plex see my medias, I have added the user plex to the group www-data. I would like to create a library watching my /var/media/admin/files/Library folder but I have a problem, Plex doesn't see neither the files or folders in /var/media. Here is a screenshot:
To finish, I have tried to connect on my server via ssh with the plex user, and it sees files and folders inside /var/media.
What am I doing wrong? Maybe it is not a permission issue?
Thanks
Update
If I change the ownership of /var/media to plex:www-data, it works. But I can't understand why it doesn't work for www-data:www-data. So it is well a permissions issue.
If I launch id plex, I have:
uid=107(plex) gid=33(www-data) groups=33(www-data)
Just to remind, here are the permissions of /var/media folder (full permissions for group...):
drwxrwx--- 4 www-data www-data 4096 Oct 30 09:01 media
I assume from your post that Plex, Linux OS, and your media are all contained on the same machine and that there are no separate computing devices being used here as that would mean additional steps are required.
In all likelyhood, plex won't be able to list your files because the mode 777 is required to list files in a directory even if the files themselves are set more restrictively than 777 e.g. 750. From what I can tell, your chmod command has set all the directory permissions to 770 which would break the listing capability. As it happens I've just yesterday written a guide over on Tech-KnowHow that covers this, and within that I have described how to set all your folders to 777 and your files to something else. That way it works with plex (and other systems for that matter). I've essentially chosen the same solutions as you in that I use the group to assign the permissions and make sure the everyone / other mode is set to apply no permissions.
There's a direct link to the article below, you'll need to click on the implementation page and look for the find command under the 'Apply correct modes' heading. I've also included how to keep your ownership consistent through samba which is useful when copying new files across. Let me know how that goes in the comments and I'll help you out where I can while it's still fresh in my mind. Good luck!

I know it is an old post, but I had the same issue and this was my solution :
After a
sudo service plexmediaserver status
I found the file used to launch the plex service /lib/systemd/system/plexmediaserver.service. This file contains the user and group which are used by plex.
So we can change the line Group=plex by your group.
PS: do not forget to restart the plex service with
sudo service plexmediaserver restart
I built the login functionality for a website on an AWS ec2 ubuntu with LAMP setup and it was working fine. The PHP files for this were located in /var/www/html. Then, to also allow login from an android device, I added and began working on the directory android_login_api in the /www folder. After adding several files and directories to this I noticed the website was no longer working and displayed "This webpage is not available" when I attempted to reach it. Despite completely removing android_login_api and attempting to revert the directory /www to just the way it was when it worked, this error remains.
I have spent a few days searching for a solution, but most answers pertain to the setup of apache which was already working fine for me. I tried restarting apache but neither index.php nor any other files I specify can be reached. I have also spent a lot of time trying to edit apache .conf files but with no luck.
Any ideas about what may have happened or if there is a specific path I need but may have accidentally altered would be greatly appreciated.
Most of access problems are caused by incorrect configuration of Virtual Hosts which seems like the problem here.
As you mentioned, the readable directory was /var/www/html and then you tried to access /var/www/android_login_api, which is not accessible by default and is specified in your virtual host file for the website. Location: /etc/apache2/sites-available
If you have done it different to this article, it will be difficult for anyone to help you. Don't create hosts in apache.conf. Read it before reading my answer further.
When you make changes to the virtual host, don't forget to use sudo a2ensite yoursite.com.conf as well as restarting apache service with sudo service apache2 restart after enabling the site.
The last thing that you should know about setting up websites is www directory owner. When you done making changes to files via FTP or SSH, run sudo chown www-data:www-data /var/www -R. www-data is the username like root used by Apache to allow external access. Otherwise the fiels will be accessible only with 0755 permissions by any other user and not 0644.
This is just a bunch of things essential to make changes and work with HTTP servers. Though my answer is not clear and I'm unable to point out your issue, I believe I've given you additional knowlege/consideration points to troubleshoot your issue. Drop a comment for more specifics.
the default install of apache in CentOS or RHEL, looking at file system permissions for html directory in /var/www/
drwxr-xr-x. 2 root root 4096 Aug 13 2013 html
My website works, and I have no issues with it, however I would like to know why and when do we need to set the directory to apache:apache?
Thank you
Since Apache is not running as root (presumably, hopefully), it only has read permissions on the directory as part of the last o=rx. This is a good default, since it means that it cannot alter the directory, only passively read and serve files from it. Everything running under an Apache process (e.g. mod_php) thereby has the same restrictions. That prevents a lot of common rookie exploits, like allowing uploads of .php files into a public web folder; because Apache/PHP cannot write into the web folder.
You should assign directories that Apache/PHP/CGI should explicitly be able to write into to apache/www-data (depending on your OS/configuration). It's not typically a good idea to do this with any directory under /var/www, you should leave that read-only as much as possible. However, adding an application-specific folder to something like /usr/local/var/<my website> with write permissions for Apache and selectively sym-linking or mod_rewriting to it is fine.
When your website need permission to modify direction/file on web app folder, you have 2 choices: 1) chmod folder to 777/666 or 2) change owner of these folders/files to apache
Sometimes, change owner is prefer to chmod because of security reason.
I have a dropbox account which sync all my website folders. and it works well on windows using my apache to test, because apache can find the directory. I have another development computer using Ubuntu 13, and i changed the document root in apache to /home/jacques/dropbox but it cant find the directory , so i opened my home folder. i saw the directory there, so i tried to access it using the terminal, it said that the directory doesnt exist.
I did right click dropbox and that said that the directory is in /home/dropbox and /home/jacques/dropbox
am i missing something important here ?
There are a few things to check here -
First is that on Ubuntu the default Dropbox directory is
/home/username/Dropbox not /home/username/dropbox. Note the capital
'D', linux file systems are case-sensitive. Make sure that you specify it with the capital D in the DocumentRoot declaration.
The second is to check what user Apache is running as and making
sure that it has permissions to view your Dropbox directory. On
Ubuntu, the default is www-data, so you might want to add yourself
to the www-data group and change the group on the Dropbox folder to
be www-data.
Alternatively, you can change the user and group that Apache runs as by editing the /etc/apache2/envvars file and by making
these edits:
export APACHE_RUN_USER=jacques
export APACHE_RUN_GROUP=jacques
You will need to restart Apache after this, and you may need to update the owner of the /var/log/apache2 directory to be you also.
I So new to linux Ubuntu and moving from windows.
The problem I have is related to ftp. This is what I am trying to do.
My websites are located in /var/www. Each website has its own root for examle
/var/www/site1
/var/www/site2
This is what I am trying to do. I would like to have a user for each site (directory) so they can access their home directory through ftp.
Looks so easy, but can't make it work. Any help or direction is appreciated.
If you want a user per site you might need to create virtual hosts in apache so that instead of the sites being located in /var/www they will be located in the user's home directory.
You can then allow users to access their home folders via ftp. These are instructions that are available on the Ubuntu site. Access them here
alternatively you can add the users as FTP users with the right permissions to the folders located under /var/www/ . Documented well in the ProFTPd website.
