Mediawiki error: File upload not working

Question

I've installed Mediawiki v1.24.1 on my server which is running RHEL7. I've installed it under /var/www/foohelp/wiki. However, when I try to upload a file, I get the following error:

[f3eae72a] /foohelp/wiki/index.php/Special:Upload Exception from line 1871 of /var/www/foohelp/mediawiki-1.24.1/includes/filerepo/file/LocalFile.php: Could not acquire lock for 'User-default.png.'
Backtrace:
#0 /var/www/foohelp/mediawiki-1.24.1/includes/filerepo/file/LocalFile.php(1174): LocalFile->lock()

#9 /var/www/foohelp/mediawiki-1.24.1/index.php(46): MediaWiki->run()
#10 {main}

If I edit /includes/filebackend/FileBackendGroup.php and modify LockManager to

'lockManager' => 'fsLockManager',

and modify permissions as follows:

chown -R apache:apache images/
chown -R 755 images/

I get the following error:

(Could not create directory "mwstore://local-backend/local-public)

I've tried most of the forums and there is no solution that seems to fix my problem. Any help would be appreciated.

Answer 1

Try to set tmp directory:

$wgTmpDirectory = "/var/www/tmp/";

And grant rights:

chown -R apache:apache tmp/
chown -R 755 tmp/

Also try to add global vars:

putenv("TMP=/var/www/tmp/");
putenv("HOME=/var/www");

And if you use imagemagick:

$wgImageMagickTempDir = "/var/www/tmp/";
