Changing the upload limit

See the MediaWiki documentation: https://www.mediawiki.org/wiki/Manual:Configuring_file_uploads#Set_maximum_size_for_file_uploads

php

The php upload limit is configured in the php.ini config file.

To find it:

$ php --ini

To edit it:

$ sudo nano /etc/php/7.4/cli/php.ini

And the search for:

• upload_max_filesize
• post_max_size

and change the values.

Then restart php:

$ sudo service php7.4-fpm restart

Localsettings.php

The MediaWiki upload limit is also configured in the LocalSettings file.

$ sudo nano /var/www/html/wiki/LocalSettings.php

Search for:

• $wgUploadSizeWarning
• $wgMaxUploadSize

and change the values.

The values are written in Bytes, this page can be used to convert mb's to bytes: https://www.gbmb.org/mb-to-bytes

nginx

Nginx also handles maximum file uploads. You can configure this maximum in the nginx conf file:

$ sudo nano /etc/nginx/sites-enabled/default

And then add in a server or location block:

client_max_body_size 5M;

Check if the nginx config is oke:

$ sudo nginx -t 

And if so, reload nginx:

$ sudo service nginx reload
