I reinstalled my open meeting server with actual version. The manual is nearly perfect from Alvaros.
I missed the part to start the kms docker automatically after rebooting machine. It seems also that the tomcat3 script does not autostart. Can someone point me in the right direction. I´m running Ubuntu 20.04. Thanks Gerald Von: dww [mailto:[email protected]] Gesendet: Samstag, 12.

I checked all the log files I could find and the error below from the log file for the kms docker container is the only thing I could find but I followed the tutorial for applicationContext.xml. The only strange thing I saw was that in /opt/logs, I see log files openmeetings.log and like openmeetings.2020-08-30.0.log however they have not been written to since 8/31/2020. Any other suggestions? I would like to get this working for a small non-profit group so we can avoid using Zoom. Should I do a direct install of KMS instead of using the docker container? However, I surmise that alot of users got this to work.

I don't understand I followed the directions in the tutorial? Are they referring to the file: var/lib/docker/containers/{container no}\config.v2.json?

But there is no error in those as far as I can see. In syslog there was a problem with rabbitmq-server which I solved but I think is unrelated. Why am I seeing no OM or KMS log files?

I have OM and KMS installed on a Linode (VM) with 8GB, 4 Cores, 160 GB SSD storage, Network Transfer-5TB, Network In-40Gpbs, Network Out-5000Mbps 8GB might be not enough, start/stop params and logs need to be examined Can you check OM and KMS logs? are there any errors? Sorry to ask, but are the locations of the logs on the server? OM logs are here: ${OM_HOME}/logs/openmeetings.log KMS logs are in /var/log/kurento-media-server/ (I would recommend to stop KMS, clean log dir, start it and then try to reproduce) Additionally system logs can be checked something like: /var/log/syslog In case KMS is being disconnected it might be 1) KMS crash (usually being reported to /var/log/kurento-media-server/error* ) 2) system kill the process due to lack of resources (should be in system logs) 3) something else ...
