From https://wikitech.wikimedia.org/wiki/Delete_a_wiki:
[x] Remove the wiki from wikimedia's wiki configuration:
[x] Remove the wiki from all.dblist and any other dblists it exists in
[x] Add the wiki to deleted.dblist
[x] Remove all other references from CommonSettings and InitialiseSettings etc.
[x] Remove the logo from w/static/images/project-logos
[] Delete privacy sensitive data (cu_changes table, rc_ip field of recentchanges)
[] Cleanup wiki replica data: {T181925}
[] Delete the _p view as well as all other views on all replica servers. The database itself is not dropped.
[] Run maintain-meta_p --all-databases --purge on all replica database servers
[x] Clean up the centralauth database. If you don't do this, the result is T30393. For small wikis it should be possible to do this manually:
[x] Run sql centralauth
[x] SELECT COUNT(*) FROM localnames WHERE ln_wiki='wikidb';
[x] If this is less than say 20,000:
[x] DELETE FROM localuser WHERE lu_wiki='wikidb';
[x] DELETE FROM localnames WHERE ln_wiki='wikidb';
[x] Likewise, the globalimagelinks table can be cleaned up:
[x] Run sql commonswiki
[x] DELETE FROM globalimagelinks WHERE gil_wiki='wikidb';
[x] Any jobs in the job queue should be deleted via wmfManageJobs.php in WikimediaMaintenance/. This avoids T171371.
