I'm using the [http://www.mediawiki.org/wiki/MediaWiki MediaWiki] software from the WikiMedia Foundation to power my wikis. MediaWiki is written in PHP5, and thus precludes the use of a multi-threaded version of [http://www.apache.org Apache].

==Use with Apache==
By default (at least on Debian), MediaWiki's PHP is run within Apache's PHP module <tt>mod_php</tt>. This can only be safely run under the multiprocess [https://httpd.apache.org/docs/2.4/mod/prefork.html mpm_prefork] paradigm. To use the (generally superior) [https://httpd.apache.org/docs/2.4/mod/worker.html mpm_worker] or [https://httpd.apache.org/docs/2.4/mod/event.html mpm_event] modules, one ought employ [https://www.php.net/manual/en/install.fpm.php php-fpm], the PHP "fast process manager" (note that FastCGI is also a thing. I don't know much about it).

===System strings===
Most strings in e.g. sidebars can be edited in the Special:AllMessages area. To see what message key a string corresponds to, add "uselang=qqx" to a URI, e.g. https://nick-black.com/dankwiki/index.php?title=User:Dank&uselang=qqx.
