LocalSettings.php is code. The file autogenerated by the web installer is a simple
case, but it can be arbitrarily complex. You could keep your per-wiki configuration
in separate files and include them based on the hostname, or as we do use an array
of setting overrides based on site and language.

https://wikitech.leuksman.com/view/Wiki_farm - I have no need to to manage a
wiki farm with some data shared and some not. Nor do I want to create a series
of custom scripts that will require hand-crafted maintenance or at least
testing, when MediaWiki is upgraded and changes. This is not a solution for
best-practice orgs where sysadmin and development are ring-fenced.

main reccommendation does not satisfy the requirement to have the source just
once, with distinct LocalSettings.php. Later suggestions also talk about
hand-crafted creation of symlinks and clones of LocalSettings.php. Again, not a
reliable / quality recommendation.

What is required is a simple distinct wiki-farm mechanism, where a sysadmin can
associate a wiki with a virtual host. Our sysadmins will not hand-craft and
maintain a LocalSettings.php where a stray curly-brace error would cause issues
for all wikis etc. They want simple configuration - as I suggessted, an Apache
one-liner(3 words) in the virtual server, with no risk of changing / introducing
PHP errors for any other wiki.

<VirtualHost *>

...
SetEnv MEDIAWIKI alphawiki

</VirtualHost>

The attached patch on bug #4509 for index.php and config/index.php recognises
this environment setting, and solves the problem for everyone, without affecting
existing users. It works for Apache versions 1.2 - 2.2, and any webserver that
can set an environment variable.

Jeff
