Running "journalctl -l -x -u opennms.service" should give you the full output to see why its failing to start.

Javier,

Debugging why OpenNMS isn’t starting is going to take a little more effort, and right now we don’t have a whole lot of information to go on. Here are some general ideas to start with, and if you can provide further details we should be able to continue to assist you.

1. Check that all of your xml files are well formed. If you run "/opt/opennms/bin/config-tester -a -v” that should test that OpenNMS can open all files and parse their contents. Another simpler way is to use the “xmllint” command to test each xml file individually.

2. Check the OpenNMS logs under /opt/opennms/logs/. On my RHEL 7 system, this is where they are. If your not on RHEL 7 or a derivative of it, then I’m not sure where the logs would be.

3. Check the manager.log. When OpenNMS starts up, this log contains the startup output for that component. If you don’t see any entries, then you could try changing its logging level in /opt/opennms/etc/log4j2.xml to DEBUG, and then you should see it log information as it cycles through initializing and starting all services.

4. Check the ends of all of the other log files to see if any of them show an error.


Good luck!

Ron
