folder permission issue 1

[synergywei]

I'm having issue with media wiki image upload folder permission. I'm not sure if this is the right place to post the question, but hopefully some linux guru can help me out on this.

I'm running:
media wiki 1.15
mysql Ver 14.14 Distrib 5.1.48
Apache/2.2.16 (Unix)
php version 5.3.3 OS: F
Linux 2.6.34.6-54.fc13.i686.PAE

I got error message "The upload directory (public) is not writable by the webserver."
I'd like to know
1. which folder is the image uploader tries write to? Is it the 'images' folder located in /var/

http://www/html/wiki

? /var/

http://www/html

is my default web folder.
2. I have already set the folder and sub folder permission for 'images' to 777, but i still can't upload anything. the folder is owned by root but 777 should allow anyone to write anything to it?
3. which user is actually running the apache process? can i assume it's apache? do i need to set the folder ownership and group all to 'apache'?

many thanks.

1. That's correct. You'll find a README file in that directory that confirms your suspicion. As you've noticed, it actually creates subdirectories under there to store the images. Unless, of course, the location has been changed by modifying $wgUploadPath in your LocalSettings.php.

2. Perhaps one of the parent directories (/var, /var/www, or /var/www/html) has some more restrictive permissions that are preventing... although, nah, ignore that, or else it wouldn't even be able to display your wiki. See below.

3. Type ps -fC httpd and look at the first column to see which user your Apache server is running under.

When you have the answer to 3, try su-ing to that user and creating a file and/or directory in that location and let us know how you go.

It may be worth moving this to the Apache forum
if you have 777 permisions & still cant wright to the directory it sounds like something is missing in the Apache settup (Web_dav support?) but I am not experienced enough to advise further.


I do not Have A.D.D. im just easily, Hey look a Squirrel!

try chown apache.apache <directoryname>

That makes the owner and group of the directory apache, and unless there are more restrictive permissions above it might help. (if you look in your /etc/httpd/httpd.conf file it should tell you who apache is running as. - that file location may vary, but locate httpd.conf should find it - )

thanks guys for the reply..

I've confirmed both methods that apache server is running as apache of group apache. i've changed ownership of the folder 'images' to apache and folder permission to 777 starting from /var/

http://www/html

--> wiki --> images, but still not working.

there is no variable $wgUploadPath in Localsettings.php, I added in with the path /var/

http://www/html/wiki/images,

still not working.

I created a password for user apache and 'su' as apache. I got this error message:

[luw@southpole images]$ su apache
Password:
This account is currently not available.

Could this be the root of the problem? how do i fix it?

many thanks.

User "apache" is probably set for "nologin" in its profile. Usually the system accounts are not set up to be logged into.

Just for fun, change the owner of the "wiki" directory to apache for testing.

Also go into both your wiki and images directory and do an ls -la to list everything. Look for files called .htaccess and if they are present temporarily rename them --> mv .htaccess .htaccess-saved. If that fixes your problem there are restrictive access restrictions in one of those files.

Just a few more ideas I would try for testing....

still not working... I have set owner, group to apache, permission 777.

would you please take a look at the LocalSettings.php file, if you see anything wrong with it? many thanks.

problem solved. SE LINUX is blocking http to access the folder
once I set SE linux to permissive or blocked, then upload is working.
