start mysql and drupal

wait a minute or so to let EC2 catch up

$ ensemble deploy --repository=principia mysql

Connect the two services

Once both the mysql and the drupal services both show a started status, add the relation between the two to activate and couple the services.

$ ensemble add-relation mysql drupal
2011-06-01 20:13:15,326 INFO Connecting to environment.
2011-06-01 20:13:21,644 INFO Added mysql relation to all service units.
2011-06-01 20:13:21,645 INFO 'add_relation' command finished successfully

now status should show

Find the drupal instance's address

ensemble status tells you which instance drupal is installed on. In the above example, drupal is installed on machine 2 or ec2-174-129-114-51.compute-1.amazonaws.com.

Open in a browser to complete the Drupal install

Open a browser to

http://<drupal instance address>/drupal6/install.php

In the above example, this would look like

http://ec2-174-129-114-51.compute-1.amazonaws.com/drupal6/install.php

More Instances - Rinse and Repeat

Scale out your drupal service by adding more units to your ensemble.

Start with a working drupal service that's already been related to a mysql service as in the example above. Then

$ ensemble add-unit drupal

will add another drupal instance and relate it to the common mysql service.

Then status shows

$ ensemble status

Now connect to the new drupal unit in a browser

http://ec2-75-101-203-234.compute-1.amazonaws.com/drupal6

and you see the same content created in the first one.
