问题
So i have read all the documentation and followed the tutorial on MySQL persistence but i can't still presist any kind of data on MySQL database.
Even though i'm puting the presistence mode = row it doesn't create any database nor table.
What am i doing wrong?
My Subscription:
python2.7 SetSubscription.py bustest4 http://localhost:5050/notify
Output:

EDIT:
So after some changes i got the log file to work and i found out that the 8081 port was already in use. Can you explain me what the ADMIN_PORT is used for, what port is it recommended to be?

Even though i set the admin port to be 8085 on the cygnus agent configuration it tries to bind to the 8081, is that normal?

回答1:
As I can see in the log, most probably Cygnus is running but not starting any Flume component (any source, channel or sink). This is due to some configuration errors.
Regarding agent_a1.conf file:
- It is missing the list of sources, channels and sinks:
cygnusagent.sources = http-source cygnusagent.sinks = mysql-sink cygnusagent.channels = mysql-channel cygnusagent.sources.http-source.channelsvalue should bemysql-channel
Regarding cygnus_instance_c1.conf:
AGENT_NAMEvalue must becygnusagent
Which version have you installed? Are you reunning Cygnus as a service or as an standalone process?
In adition, you could try to start Cygnus in DEBUG mode? Simply edit the /usr/cygnus/conf/log4j.properties file.
Do the proposed changes and see how the log evolves! :)
EDIT 1
Such a "fatal error" is not so fatal. It was a bug appearing in Cygnus 0.7.1, currently fixed. Anyway, even in 0.7.1 it did not affect the normal behaviour of Cygnus since the management port is only used for retrieving the version, nothing important.
Did you try to send some update context to Orion in order a notification is received by Cygnus? Even by simulating the notification? Please, see the Cygnus Quick Start Guide for an example about how to make such a simulation.
EDIT 2
Cygnus packages names es.tid.fiware.fiwareconnectors.cygnus... were replaced by com.telefonica.iot.cygnus... from release 0.8.0 (or maybe 0.9.0).
