Another way to do this is to pass an argument (or define a variable) to the lms and nginx role which will cause the service to be started.

in the top playbook:
```
roles:
  - lms  lms_start=true
...
```


in the lms role, as either a handler or a task

```
- name: Start the LMS
  service: name=lms state=started
  when: lms_start is true

```

Also something similar for http auth.
