How to Deploy a WAR File to Apache Tomcat ? | Tomcat | KK HindiGyan

I do the same steps and as same deploye on tomcat server but I didn't get appropriate results. It give 404 not found error.
Is there any other configurations in STS or in tomcat server which I miss except in this video????

External tomcat me database ke confirmation bhe add karna hota hai, tabhi application database se connect hoga
