Run Tomcat as a normal identity

1: The Tomcat port is forwarded using iptables because the non-root user cannot use the following port 1024

iptables-t nat-a prerouting-p tcp-m tcp--dport 80-j REDIRECT--to-ports 8080
Iptables-t nat-a prerouting-p udp-m UDP--dport 80-j REDIRECT--to-ports 8080

2: Change site permissions

Chown-r tomcat:tomcat/usr/local/tomcat/

3: Write a service startup script to specify who the Tomcat service is running
