Hi,
I have been setting up quite a few Mediawikis in both Windows and Linux, and
it occurred to me it would be handy to know a bit about how the wikipedia is
set up. Is there any up to date information about how which versions of
software it runs (assuming that's not considered a security risk), and what
it prefers?
The particular info I was pondering:
* I know they use APC, but do they use FastCGI or just mod_php? Is there a
good page on hints as to how best configure this?
* Mysql - is there a central cluster for updates, and then a bunch of
slaves, I looked at this page:
https://wikitech.leuksman.com/view/Server_roles but could work out if there
were multiple machines as master, or just a single machine master, with lots
of slaves for a single wiki eg EN.
* Mysql - they still use 4, is this for stability, performance or some other
reason?
* Do they use a standard linux flavour eg ubuntu or Red Hat, or are the
servers all on a custom kernel.
* How do they manage upgrading the software, do different servers run on
different versions. Presumably there is a test environment, but do they have
to go read only at all?
Many thanks for any insights into managing this complex environment,
Alex Powell
