Fatal error when starting orion context broker

Question

My orion context broker does not start and when I enter the command /etc/init.d/contextBroker start I get this message

[root@context-broker ~]# /etc/init.d/contextBroker start
Starting contextBroker (via systemctl):  Job for contextBroker.service failed because the control process exited with error code. See "systemctl status contextBroker.service" and "journalctl -xe" for details.
                                                           [FAILED]

The systemctl status contextBroker.service commannd gives this message

[root@context-broker ~]# systemctl status contextBroker.service

Hint: Some lines were ellipsized, use -l to show in full.

Also the /tmp/contextBroker.log file looks like this

time=2019-05-24T11:41:12.971Z | lvl=FATAL | corr=N/A | trans=N/A | from=N/A | srv=N/A | subsrv=N/A | comp=Orion | op=rest.cpp[1753]:restStart | msg=Fatal Error (error starting REST interface)

I checked if mongodb is running and it is running correctly. UPDATE With some searching I realised I had to kill the pid of the process and after I did that the service successfully starts according to the messaags but I find it doesnt actually work. When I ask for the status I get the following:

[root@context-broker centos]# /etc/init.d/contextBroker status
● contextBroker.service - LSB: run contextBroker
   Loaded: loaded (/etc/rc.d/init.d/contextBroker; bad; vendor preset: disabled)

May 26 18:34:49 context-broker.novalocal contextBroker[16319]: Starting contextBroker...                         [  OK  ]

The log file has the same message as previously. With some searching again I believe the cause is that the service doesnt have a daemon(??). So if that is the case how do I add one?

Answer 1

Normally when getting the error starting REST interface, it's because there is already a broker running, which means the port is already taken. Make sure there is no broker already running.
