Tomcat's defaults are 8080 and 8443, for HTTP and HTTPS respectively.
The GIS Server is expecting Tomcat's ports to be bound to 80 and 443. In order to bind to ports this low in Linux, you'll need to use IPTables, authbind or something else to reroute. Don't run Tomcat as root.
Can you get to Tomcat on port 443?
Thanks Randall Williams, Tomcat is not getting up on 443 (https), and I am able to get up Tomcat on 8443. I am not running tomcat on root. Could you please guide how to re-route usiing IPTables / AuthBind?
Here's a resource - you'll need to run these commands to edit the iptables as root or as a member of the SUDOers group (you can't run sudo (Super-User-DO) unless you're in the SUDOers group).
sudo iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080
sudo iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 443 -j REDIRECT --to-port 8443
