This page describes my SimpleFarm experience.
Installation edit
I use a MediaWiki 1.19.1 farm with the SimpleFarm 0.1rc extension that contains three wikis (PROJECT1, PROJECT2, PROJECT3) that share the same productive database. A second implementation contains the same wikis sharing a different test database for testing purpose. I keep all settings in a separate directory parallel to the mediawiki installation directory. Every wiki shall be called using a 'pretty' clean URL.
Installation Directories:
http://www.proddomain.com/wikiroot/mediawiki/ http://www.proddomain.com/wikiroot/settings/ http://www.proddomain.com/testroot → http://www.testdomain.com http://www.proddomain.com/testroot/wikiroot/mediawiki/ → http://www.testdomain.com/wikiroot/mediawiki/ http://www.proddomain.com/testroot/wikiroot/settings/ → http://www.testdomain.com/wikiroot/settings/
Wiki URL:
http://www.proddomain.com/project1/Main_page http://www.proddomain.com/project2/Main_page http://www.proddomain.com/project3/Main_page http://www.testdomain.com/project1/Main_page http://www.testdomain.com/project2/Main_page http://www.testdomain.com/project3/Main_page
Settings edit
Due to the redirect from www.proddomain.com/testroot/wikiroot to www.testdomain.com/wikiroot, I can use the same setup files with settings in both domains.
