Open Source Document Management System | OpenKM

After installing from the OKMInstaller.jar, The last step is to start tomcat but getting error:
Job for tomcat.service failed because the control process exited with error code.
See "systemctl status tomcat.service" and "journalctl -xe" for details.


after doing journalctl -xe, I get :

Unit tomcat.service has begun starting up.

Thanks in advance

Did you have a previous tomcat installed in your computer ? Consider removing it before installing OpenKM. I think in community edition the installer still is creating a servivice script named tomcat at /etc/init.d. If you have previously installed tomcat from repositories then you already have an script with same name, might be here is the issue.

In future we have planned rename tomcat service to openkm service to do not get this kind of issues. Anyway is not a good idea have several tomcats sharing the same computer.
