MediaWiki

MediaWiki is the wiki software we use for Sasara. It's also used on Wikimedia Foundation projects like Wikipedia and Wikimedia Commons.

Change homepage

Update link on MediaWiki:Mainpage to point to the new target home page.

Image uploads

Enabling uploads

Open LocalSettings.php, and change this option:

$wgEnableUploads = true;

Make sure the uploads folder is writable by the web server process. We run ours in a separate zfs dataset with execution off and quotas for security:

zfs create $DATASET/wiki/uploads
zfs set exec=off $DATASET/wiki/uploads
zfs set quota=1G $DATASET/wiki/uploads

Improve quality

The default quality setting for image compression is 80, which isn't great.

Open LocalSettings.php, and add the following option under wgEnableUploads:

$wgJpegQuality = 96;

Increasing size

Open php.ini, and change this to what you want:

upload_max_filesize = 8M

If you run nginx, you may need to add this to your nginx.conf file to prevent HTTP 413 Entity Too Large errors:

http {
    client_max_body_size 8M;
}
