Please, ANSWER this question AT https://stackoverflow.com/questions/32989596/fiware-can-not-start-cygnus-as-service

Question:
Fiware: can not start cygnus as service

Description:
I installed cygnus using RPMs on fiware image CentOS-7-x64 and I can't 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?

Here is my configuration files:

agent_mongo.conf

cygnusagent.sources = http-source
cygnusagent.sinks = mongo-sink
cygnusagent.channels = mongo-channel

#=============================================

1. source configuration
2. channel name where to write the notification events
   cygnusagent.sources.http-source.channels = mongo-channel
3. source class, must not be changed
   cygnusagent.sources.http-source.type = org.apache.flume.source.http.HTTPSource
4. listening port the Flume source will use for receiving incoming notifications
   cygnusagent.sources.http-source.port = 5050
5. Flume handler that will parse the notifications, must not be changed
   cygnusagent.sources.http-source.handler = com.telefonica.iot.cygnus.handlers.OrionRestHandler
6. URL target
   cygnusagent.sources.http-source.handler.notification_target = /notify
7. Default service (service semantic depends on the persistence sink)
   cygnusagent.sources.http-source.handler.default_service = def_serv
8. Default service path (service path semantic depends on the persistence sink)
   cygnusagent.sources.http-source.handler.default_service_path = def_servpath
9. Number of channel re-injection retries before a Flume event is definitely discarded (-1 means infinite retries)
   cygnusagent.sources.http-source.handler.events_ttl = 10
10. Source interceptors, do not change
    cygnusagent.sources.http-source.interceptors = ts gi
11. TimestampInterceptor, do not change
    cygnusagent.sources.http-source.interceptors.ts.type = timestamp
12. GroupinInterceptor, do not change
    cygnusagent.sources.http-source.interceptors.gi.type = com.telefonica.iot.cygnus.interceptors.GroupingInterceptor$Builder
13. Grouping rules for the GroupingInterceptor, put the right absolute path to the file if necessary
14. See the doc/design/interceptors document for more details
    cygnusagent.sources.http-source.interceptors.gi.grouping_rules_conf_file = /usr/cygnus/conf/grouping_rules.conf

1. ============================================
2. OrionMongoSink configuration
3. sink class, must not be changed
   cygnusagent.sinks.mongo-sink.type = com.telefonica.iot.cygnus.sinks.OrionMongoSink
4. channel name from where to read notification events
   cygnusagent.sinks.mongo-sink.channel = mongo-channel
5. FQDN/IP:port where the MongoDB server runs (standalone case) or comma-separated list of FQDN/IP:port pairs where the MongoDB replica set members run
   cygnusagent.sinks.mongo-sink.mongo_hosts = 127.0.0.1:27017
6. a valid user in the MongoDB server (or empty if authentication is not enabled in MongoDB)
   cygnusagent.sinks.mongo-sink.mongo_username =
7. password for the user above (or empty if authentication is not enabled in MongoDB)
   cygnusagent.sinks.mongo-sink.mongo_password =
8. prefix for the MongoDB databases
   cygnusagent.sinks.mongo-sink.db_prefix = kura_
9. prefix pro the MongoDB collections
   cygnusagent.sinks.mongo-sink.collection_prefix = kura_
10. true is collection names are based on a hash, false for human redable collections
    cygnusagent.sinks.mongo-sink.should_hash = false

#=============================================

1. mongo-channel configuration
2. channel type (must not be changed)
   cygnusagent.channels.mongo-channel.type = memory
3. capacity of the channel
   cygnusagent.channels.mongo-channel.capacity = 1000
4. amount of bytes that can be sent per transaction
   cygnusagent.channels.mongo-channel.transactionCapacity = 100

cygnus_instance_mongo.conf :

1. Who to run cygnus as. Note that you may need to use root if you want
2. to run cygnus in a privileged port (<1024)
   CYGNUS_USER=cygnus

1. Where is the config folder
   CONFIG_FOLDER=/usr/cygnus/conf

1. Which is the config file
   CONFIG_FILE=/usr/cygnus/conf/agent_mongo.conf

1. Name of the agent. The name of the agent is not trivial, since it is the base for the Flume parameters
2. naming conventions, e.g. it appears in .sources.http-source.channels=...
   AGENT_NAME=cygnusagent

1. Name of the logfile located at /var/log/cygnus. It is important to put the extension '.log' in order to the log rotation works properly
   LOGFILE_NAME=cygnus.log

1. Administration port. Must be unique per instance
   ADMIN_PORT=8081

1. Polling interval (seconds) for the configuration reloading
   POLLING_INTERVAL=30

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