Have you placed the WAR file in the folder? It seems it should be in /home/dhis/tomcat-dhis/ and I believe there you should see there a webapps folder and the WAR should be inside.

Yes it is inside webapps folder @jaime.bosque

Yes i have placed a war file inside the folder

Ok, checking at the logs again … it seems that your user dhis is not being able to authenticate on postgres. Can you double check that you created the user properly and that it matches your dhis.conf (user / password)?

Okay let me start the installation again
