  4. installs many of the extensions using `git clone ...`, making it easier to update in the future
  5. updates the vhost config to block access to git files, and more generally: ".*\.(svn|git|hg|bzr|cvs|ht)/.*"

  23. enable https via nginx
  24. enable cache via varnish
  25. moves LocalSettings.php outside the docroot, replaces the existing LocalSettings.php with a simple file that does a php include of the LocalSettings.php file outside the docroot.
  26. moves the ose logo into the uploads directory
  27. does a sed text replacement within the db data for all http strings to use https instead for 'https://www.youtube.com/embed/', 'https://static.issuu.com/webembed/', 'https://scrumy.com/', 'https://embed.ted.com/', & 'https://player.vimeo.com/'
  28. reduces the privileges of the wiki user on the db to only SELECT, INSERT, UPDATE, & DELETE
  29. adds an additional "superuser" db user with all permissions on the db for maintenance scripts (creds stored in keepass, not on the server)
  30. hardens the file permissions
  31. prevents the web server from executing php files in the uploads directory
  32. changes LocalSettings.php to ban IE6
  33. changes LocalSettings.php to make the max upload size 1M. It warns > 500k.
  34. changes LocalSettings.php to disable use of imagemagick as we don't let php exec()

  40. changes LocalSettings.php to use "MiserMode" to decrease db-heavy operations
  41. changes the caching settings of mediawiki to use APCU (via CACHE_ACCEL) for the MainCache & MessageCache. Else it uses the db, and therefore every load includes a cpPosTime cookie, which causes varnish to hit-for-pass on every page.
  42. changes the caching settings of mediawiki to use the DB for ParserCache
  43. changes the caching settings of mediawiki enable the SidebarCache
  44. changes the caching settings of mediawiki cache interface messages to files on disk outside the docroot ($IP/../cache/)
