When Deploying web app directory tomcat application server got hanged ?

I was trying to install Tomcat application server(Apache Tomcat/7.0.61) in an Ubuntu server(Ubuntu 15.9).
When I started the tomcat server during deployment stage, it got hanged and after that I tried running http://localhost:8080 on mozilla browser,but It’s taking long time to load and nothing happened.I have java version "1.7.0_79" installed on my system. I have searched this query on various -Link Removed By Moderator- but I didn’t get appropriate solutions. Looking for a correct solution here ..

You should take a look at catalina.out for errors.
