EdWeb Pandemic Docs

We only have one live EdWeb distribution site, web.inf.ed.ac.uk.

The only common tasks are applying updates, be it feature updates or security updates. It is recommended that you don't just do vanilla Drupal updates, either via the web or via drush, and that you only apply official EdWeb distribution updates released by IS, which will contain any applicable security updates. If in doubt though, speak to the IS website support team, and they can advise you what can be updated outisde the usual procedures.

See the main docs on our use of the EdWeb distribution at SchoolEdWeb, which include a link to the disaster recover page at WebInfEdAcUKDisasterRecovery.


At the time of writing, web.inf.ed.ac.uk is hosted on a VM called clod.inf in Appleton Tower machine room.

A few #defines and the live/edweb-school.h header configure the instance. Those alone will not give you a working site, some initial manual configuration of a database is required, but that is not described in these pandemic docs.

The unique configuration, database, extra backups etc are all in /disk/data/ the EdWeb site itself is in /disk/data/edweb/.

Log files:

  • /var/lcfg/log/apacheconf.access (and .errors)
  • /var/lcfg/log/apacheconf.edweb.access (and .error)
  • /var/lcfg/log/apacheconf.edwebssl.access (and .error)
  • /var/log/httpd/modsec_audit.log

Apache configured via LCFG apacheconf, in the usual place /etc/httpd/

Like any drupal site, it requires MySQL/MariaDB to be up and running. We use MariaDB , though it is managed via the mysql component. The database is /disk/data/mysql/

The public pages are accessible via HTTP. Currently HTTPS is for authenticated access only via Cosign. Authorisation is done via EdWeb's own mechanisms.

There is a mirror site, web-dr.inf, which takes a mirror of the live site every couple of hours. It is not accessible outside our firewall by default.


If the site is down then check the basics, is the host up and reachable, is apache and mysql running?

See TraditionalWebTroubleshooting

Try rebooting.

The problem may be an "EdWeb" thing, in which case Sego from the InfComms team may be able to help.

If you've had a disaster, and the VM has been destroyed or is inaccessible for some reason, then follow the instructions on WebInfEdAcUKDisasterRecovery
