See Heterogeneous deployment for now

Operating on current server

• sync-common
  • syncs /home/wikipedia/common -> /apache/common on this server

Operating on mediawiki-installation boxes via dsh

These scripts all sync to: apaches, image scalers, and misc other hosts running apache (search servers, live html snapshot browsers, the secure server, etc)

• sync-common-all
  • syncs /home/wikipedia/common -> /apache/common
• sync-common-file
  • syncs a given file from /home/wikipedia/common -> /apache/common
• sync-dblist
  • syncs *.dblist from /home/wikipedia/common -> /apache/common
• sync-docroot
  • syncs /home/wikipedia/common/docroot -> /apache/common/docroot
• sync-file
  • Checks PHP syntax and syncs a given file from /home/wikipedia/common/wmf-deployment -> /apache/common/wmf-deployment
• scap
  • Checks PHP syntax, rebuilds localization caches and texvc, and syncs /home/wikipedia/common/wmf-deployment -> /apache/common/wmf-deployment

Operating on apaches and image_scalers dsh groups

• sync-apache
  • Syncs /home/wikipedia/conf/httpd to /apache/conf
    • note these files are not in /home/wikipedia/common and are *not* copied by sync-common family

Mysterious or obsolete things?

• scap14, scap14-1, scap14-2
  • obsolete from MediaWiki 1.4 days
• scap15, scap15-1, scap15-1skins
  • 'scap15' is actual script for 'scap' currently; probably could use cleanup
• sync-file13, sync-file14
• sync-file-log14 ?
• sync-to-seoul
• sync-common-allphp
• sync-common-clean
• sync-common-it
• sync-common-php
• sync-common-php-x

No idea what these are

• sync-mirror-dag.sh
• sync-mirror-fedora.sh
• sync-users-and-groups.sh
• syncout
• sync-cgibin

Example apache sync

1. cd /home/wikipedia/bin on fenari
2. (optionally) run ./sync-apache-simulated which just has an "-n" added to the rsync commands. (--dry-run | show what would have been transferred)
3. if that looks fine, actually sync: ./sync-apache
4. connect to a single random "srv" server, confirm the expected change has arrived here, and restart Apache to check your change did not break things.
5. if that also looks fine, use apache-graceful-all to restart all Apaches
6. This is an example from a case that just added 2 redirects, so depooling/ repooling was not necessary but it might be in other cases. Make sure first and please add a link here that describes depooling / repooling.
7. After this you might want to purge a URL from Squid cache. Also see Squids.
