Aegir

half-way through a big refactor. todo; move things from here to other places.

Aegir is a site management distribution.

• Aegir
• Aegir file system structure
• Aegir contexts

Overview

Aegir uses Drupal multisite features to share one Drupal codebase install as a 'platform' between sites. Distributions are equal to platform+site, i.e., turnkey solutions. Content can be shared (migrated) between sites using an updated or different platform (with the same content modules, natch).

A platform and site distribution is created from a .make and .info by the Drush Provision plugin that powers the backend of Aegir. The Profiler library is installed with the .make and uses a .info file to specify modules to be initialised, including site sections/etc. from the Features module plus configuration settings via the Strongarm module. Provision initialises a site on that platform and installs the platform+site in Aegir.

Features and theme are stored using Git, --working-copy can be used to build a dev site then content can be migrated from live for testing. Dev platform is perfected, then rebuilt as live without --working-copy.

todo; use hosting_site_git and working-copy patch

Dev/production workflow

• Drupal deployments & workflows with version control, drush_make, and Aegir (mig5, Oct 28 2009)
• Using drush hosting-import to auto-create your platform node (and other entities) (mig5, Jan 11 2011) - Updated workflow on Aegir mailing list
• From Zero to Distribution using Features, Profiler, and Drush Make (dimitri, March 9, 2011)

Provision

• Provision - the Aegir backend
• API reference
• purge option for platforms (--force)

php /var/aegir/drush/drush.php @hostmaster hosting-cron --debug

• Manage your Aegir system from the command-line

Hostmaster

• Migrate sites from one Aegir to another (Apache)

• remote_import - Drush extension that allows you to fetch remote sites from remote Aegir servers
  • http://drupal.org/project/hosting_remote_import hosting_remote_import] - module that provides a UI for remote_import

Backups

• http://drupal.org/project/provision_reinstall
  • http://drupal.org/project/hosting_reinstall

• http://drupal.org/project/hosting_backup_gc - allows you to specify how long Aegir should retain backups for

Migration between Aegirs

• Remote import - Provision, Remote import - Hostmaster - Drush extension allows you to fetch remote sites from remote Aegir servers.

Managing workflow

• http://drupal.org/project/hosting_queue_runner - tasks are run as soon as possible instead of waiting for a cron run. This makes Aegir appear much more responsive. [1]

• https://github.com/computerminds/aegir_make_working_copy - provides git working copy option un hostmaster gui for dev sites. - broken [2]

• http://drupal.org/project/hosting_site_git - hostmaster+provision
• http://drupal.org/project/provision_git - backend only

• Hosting Features - provides a Task to Hostmaster that provides integration with a site's Features. It is currently in development but works for the most important task: Update & Commit Features
