I have installed cygnus using RPMs on my CentOS 7.0 , but I can't started as service:
[centos@cygnus-mongo ~]$ sudo service cygnus start
Starting cygnus (via systemctl): Job for cygnus.service failed. See 'systemctl status cygnus.service' and 'journalctl -xn' for details.
[FAILED]
Here is the errors log:
