Documentation

Aegir master install goes in /var/aegir. Not as tuned and featured as the Octopus Aegir install. Best practice is to use Octopus for production.

Caching

  • Redis is an open source, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.

New system uses only Redis cache and the same configuration for all Drupal 6 and Drupal 7 platforms. This new system doesn't require any extra module to be enabled in any site. Complete integration is already enabled by default for every platform/site installed by default and for every custom platform as before - the next day after first site on the custom platform has been created. You can disable this caching layer using the same modules/cache/NO.txt control file as before. While there is just one cache engine (Redis) used, there is also an automatic, instant failover to standard database caching, just in case Redis is not available for some reason. You can also disable Redis cache on the fly for debugging by adding ?noredis=1 to any URL.
