While creating a solution I tried starting cygnus using RPMs on fiware image CentOS-7-x64 but I am unable to start it as a service, Here is my logs:
[centos@cygnus-mongo conf]$ sudo service cygnus start
Starting cygnus (via systemctl): Job for cygnus.service failed. See 'systemctl status cygnus.service' and 'journalctl -xn' for details.
[FAILED]
[centos@cygnus-mongo conf]$ sudo journalctl -xn

Actually the directory /var/run/cygnus was not created, is it going to be created automatically?

Edit: add logs after lunching cygnus as a standalone application:
