QUESTION
========
SERVICES.1: There is talk about "services" which are called cms, lms, etc... Are these ubuntu upstart services? should they automatically be created by the playbooks?
SERVICES.2: How can we stop/start/restart "the services". is there a proposed procedure?

ANSWER
=============
SERVICES.1:

Yes, each role from the ansible playbooks provides different services, which are setup as Ubuntu upstart scripts. 

For example, the edxapp role creates the following upstart services, using templates in `playbooks/roles/edxapp/templates/*.conf.j2`

```
# ls playbooks/roles/edxapp/templates/*.conf.j2
playbooks/roles/edxapp/templates/cms.conf.j2                 playbooks/roles/edxapp/templates/edx-worker-lms.conf.j2  playbooks/roles/edxapp/templates/lms-preview.conf.j2
playbooks/roles/edxapp/templates/edx-worker-cms.conf.j2      playbooks/roles/edxapp/templates/edx-workers.conf.j2     playbooks/roles/edxapp/templates/lms-xml.conf.j2
playbooks/roles/edxapp/templates/edx-worker-lms-xml.conf.j2  playbooks/roles/edxapp/templates/edxapp.conf.j2          playbooks/roles/edxapp/templates/lms.conf.j2
```

These templates are evaluated and copied to `/etc/init` on the VM being configured.


SERVICES.2:

To stop a service:

```
# service <name> stop
```

To start a service:

```
# service <name> start
```

To restart:

```
# service <name> restart
```

Also, you can either start/stop the LMS & CMS services individually (ie, `service lms-xml restart`), or all at the same time using the `edxapp` service:

```
# service edxapp restart
```
