New Knime Server Ubuntu install

New to community. I need some help, I am following the server install guide
and did a fresh install. Everything is working almost great except these two problems.

Knime server/executor does not start when rebooting ubuntu. I cannot see the webpage

sudo cp -r <knime_server>/install-data/linux-runlevel-templates/systemd/. /
systemctl enable knime-server.service
systemctl enable knime-executor.service

Fresh install
Ubuntu 22 LTSC
No License, just playing around for now

Also the second problem is this, not sure if this is related to having a license or not.

Hi @kyoshi66,

Welcome to the KNIME community.

Good to hear that you were able to install the KNIME Server using our Guide almost without glitches.

Regarding the 2 issues: I am not sure if you replaced the <knime_server> placeholder with the path you installed the KNIME Server into. You can check if the services are installed in general by requesting their states:

systemctl status knime-server.service
systemctl status knime-executor.service

Looking at the output of both commands you should see something similar like the following if the services are properly installed:

● knime-server.service - KNIME Server

Mai 02 15:24:51 knimemr systemd[1]: Starting KNIME Server...
Mai 02 15:24:51 knimemr server[182799]: Tomcat started.
Mai 02 15:24:51 knimemr systemd[1]: Started KNIME Server.

Looking at the “Loaded” line of the output you will see an enabled if the autostart is activated before the preset part, otherwise a disabled.
Hint: The status requests as well as the enablement of the services might need administrator rights via sudo to work properly.

The blocked access to the webportal contents is -as you assumed already- caused by the not applied KNIME Server license. This would also cause the executor service to fail as it does not get the needed (and licensed) executor cores from the KNIME Server.

Feel free to reach out to us via Contact us | KNIMEContact Customer Care in case you would like to try out the KNIME Server on your own.


So it looks it the status for both server and executor shows enabled.
If you have any other ideas, followed the pdf to the tee.
Also made a support ticket
