Orion Context Broker doesn't start

I've been working with FIWARE for a school project, I had previously installed Orion and was able to post data to the Context Broker. I rebooted the system since I made some other changes to my set up and Orion has stopped working ever since.

I was trying to start the Context Broker from my command line and its starts. However it doesn't start the Context Broker. The netstat -tupln command doesn't display that the port 1026 is in use and the JSON file which had previously posted the data to FIWARE isn't displayed anymore.

Solution

  • have you checked that MongoDB is running ?

    have you checked the content of the /tmp/contextBroker.log file?

    Thanks
