I have a 4 node setup of openstack liberty. 1 controller , 2 compute node
and 1 network node. I did a apt-get barbican-api barbican-worker
barbican-keystone-listener and installed the components. The deployment is
pointing to the ubuntu liberty repository. The database used by all the
services is mariadb.

After modifying the barbican.conf, I did barbican-db-manage upgrade and
restarted the services.

These are the status of the services
root at controller1:~# service barbican-keystone-listener status
barbican-keystone-listener stop/waiting
root at controller1:~# service barbican-worker status
barbican-worker stop/waiting
root at controller1:~# service barbican-api status
barbican-api start/running, process 36754

This is a section of the barbican-api.log file

ImportError: No module named barbican.api.app
OOPS ! failed loading app in worker 1 (pid 6677) :( trying again...
worker respawning too fast !!! i have to sleep a bit (2 seconds)...
Respawned uWSGI worker 1 (new pid: 6748)
