[MediaWiki-l] Permission and file ownership

[Daryl Rose]

I just recently migrated the wiki to a new environment.  It was on a SLES
11 SP4 server running in a lampp and installed via Bitnami.  Because of
security issues, I built a new server, CentOS 7.x.  This is a MediaWiki
v1.25.2 environment.

What should the owner and group be set to?  Currently, they're set to
root/daemon.  That was what Bitnami had the owner and group set to in the
initial installation.  I copied the entire site to the new system retaining
the permissions.  Now users are getting errors uploading images.

The errors that users are receiving are similar to:

[a10a3fd5] /mediawiki/Special:Upload MWException from line 1856 of
/var/www/html/mediawiki/includes/filerepo/file/LocalFile.php: Could not
acquire lock for 'Andorra.png.'

Research keeps pointing to permission issues, but the permissions are the
same in both environments.

I do have another environment that was set up on another server.  It still
uses lampp, but it does not use Bitnami.  After the experience with
Bitnami, I decided to eliminate it, and just install MediaWiki directly.
Anyway, the ownership and permissions are a bit different on that
installation.  Owner and group are both root, and the permission on the
images directory are 777.   I personally think that wide open permission on
the images directory is a bad idea and will not set those same permissions
on the new installation.  But, I've read a number of times in different
forums that was what resolved this for others having the same errors.

I hesitate just changing the owner and group on the wiki to root/root and
open up the images directory to the world.  So, what are the best
permission settings?  What should the owner and group be, and what
permissions does the images directory have to be?

Thanks

Daryl

What username does the web service use? www? Whatever user account it uses
needs write permission to the images diectory.

I see.   httpd.conf file has the user and group set to apache/apache.
Simple resolution.  I'm able to upload images.

Thanks John.
