unable to start Fiware Cygnus as a service - fiware

Question

I installed fiware cygnus using RPM on my centOS 7 but I can't start it as service. I got the following error:
[root#localhost cygnus]# sudo service cygnus start
Starting cygnus (via systemctl): Job for cygnus.service failed. See 'systemctl status cygnus.service' and 'journalctl -xn' for details.

[root#localhost cygnus]# systemctl status cygnus.service -l

not sure what to put as name of the agent in the configuration file: cygnus_instance_1.conf since it did not reconize the agent name
# Name of the agent. The name of the agent is not trivial, since it is the base for the Fluleters
# naming conventions, e.g. it appears in .sources.http-source.channels=...
AGENT_NAME= mongo-channel
Here is my complete configuration files:

# one of them (this example shows how to configure 3 sink types at the same time). Even, you can define more than one
# sink of the same type and sharing the channel in order to improve the performance (this is like having

Looking to the above error I saw that it can't find the file "/var/run/cygnus/cygnus_1.pid" so I created an empty file to bypass this error but I got a new one:

Job for cygnus.service failed. See 'systemctl status cygnus.service' and 'journalctl -xn' for details.

Answer 1

According to your agent_1.conf configuration, the AGENT_NAME within cygnus_instance_1.conf must be cygnusagent. I.e.:
AGENT_NAME = cygnusagent
In addition, the CYGNUS_USER should be cygnus, since this is the user the RPM creates when installing the software.
