This mediawiki package supports multiple instances, sometimes also
called Wiki Farms or Wiki Families, but you can use it for a single
instance just as well.
This works by running mw-createinstance <path>, where <path> is the
new desired location of your wiki(s) like
mw-createinstance /srv/my.host/wiki
Note that the parent directories must exist.
You also need to create an Apache config entry (if you use Apache for
serving mediawiki) like
DocumentRoot /srv/my.host/wiki
Alias /skins /usr/share/mediawiki/skins
<Directory "/usr/share/mediawiki/skins">
AllowOverride None
Require all granted
</Directory>
<Directory "/srv/my.host/wiki">
SetEnv MW_INSTALL_PATH "/srv/my.host/wiki"
AllowOverride None
Require all granted
</Directory>
(this example is for short URLs, e.g. ones w/o a "/wiki/" in the URL)
