Question

Which OS are you trying to start your app.? You may need Sudo access to start a process under 1024 in linux based systems. http://stackoverflow.com/questions/10182798/why-are-ports-below-1024-privileged — Praneeth Ramesh, May 10 '17 at 16:45

On U/LINUX systems you are not allowed to open ports < 1024 as non root user. You can run your app as root (i would not recommed this) or put something as a proxy in front of your app (e.g. Apache).

Also I suppose that you can add some iptable rules to redirect the traffic from 80 to the port of your application, but I would not go this way.

When i deploy in achape-tomcat it not allowing tomcat to startup, it is working fine on my local system using sudo. – Santosh May 10 '17 at 17:35
Yes, by using sudo you actually run the process with super user (root) rights. You can not run your tomcat on ports < 1024 as not root user either. – thopaw May 10 '17 at 17:37
