Warning: Requests for images in your uploads directory should answer with the HTTP header X-Content-Type-Options: nosniff to protect browsers from potentially unsafe files.
It is highly recommended to configure appropriate response headers on your webserver before enabling uploads.

Upload security

Upload security - Manual:Security - MediaWiki
https://www.mediawiki.org/wiki/Manual:Security#Upload_security

<Directory "/...">
  # Tell browsers to not sniff files
  Header set X-Content-Type-Options nosniff
</Directory>

Dependency Check

For convenience:

sudo ln -s /var/www/html /www

Test php:

echo "<?php phpinfo(); ?>" > /www/phptest.php

http://x.x.x.x/phpinfo.php

Look for MySQL and obviously the processed php page.
