  6. Drush: (Very) Quick Tour • Stands for DRUpal SHell • A command line shell interface to Drupal • Allows an administrator to execute commands against a Drupal site without opening a browser

  7. Multi-Site Drupal • “Multi-site allows you to share a single Drupal installation (including core code, contributed modules, and themes) among several sites.” - d.o • Each site gets a directory in the sites/ directory • Each site has its own database, therefore its own content/users/settings/etc. • Only upgrade the code once

  17. How AEgir works • A system account is created for AEgir to run drush command via cron job • This looks at the task queue and performs tasks • Apache is configured to include configs within the AEgir directory • AEgir user account has privilege to reload Apache • A privileged database account is stored and used to create databases and site accounts

  18. Real world problems • Installing is hard (but easier now with install script) • Adds large complexity • File permission issues • Libraries installed in sites/all/libraries • No module handling • A lot of stuff can go wrong!

  19. Advanced usage • Use drush make to create a new platform (build) for each site (application) • Support for multiple servers • Sever to server site migration and cloning • Client roles allow users to administer their own sites • Dave Hall (http://davehall.com.au/) has ~2100 sites running one AEgir instance
