How to view Tomcat log file?

Question

I'm getting errors while deploying Headwind MDM. How can I get the details?

Answer 1

On Tomcat 9, you can view logs by the command

journalctl -u tomcat9.service

This will display logs in a viewer like "less".

To follow logs, use the command

journalctl -f -u tomcat9.service

To write the full log into a file, use the command

journalctl -u tomcat9.service > tomcat-log.txt

If you're using an older version (Tomcat 8), you can get the log file by the following path:

/var/lib/tomcat8/logs/catalina.out
