Details

An array of database names. E.g.,

$wgLocalDatabases = [ 'wikipedia', 'meta', 'news' ];

This is used for e.g. $wgConf (SiteConfiguration). Note that $wgConf->wikis should be the same as $wgLocalDatabases.

It is needed to run a wiki family , for example by using Extension:CentralAuth .

It is also in use by some maintenance scripts like:

User rights on other wikis on this site can be administered from a single developer account (permission: userrights-interwiki).

Troubleshooting

<translate> Tracked in [[<tvar name=1>phabricator:</tvar>|Phabricator]]</translate>
<translate> Task <tvar name=1>T289704</tvar></translate>

For unclear reasons, since this variable is empty as default, some maintenance scripts will do nothing as default. Some of these are:

• clearInterwikiCache.php - clear the interwiki cache
• rebuildmessages.php - clear messages
• cleanupSpam.php - delete pages with spam URLs

In fact, these scripts do operations on your "local databases" but $wgDBname is not considered one of them as default. A useful contribution would be to clarify this.
