How to change the port of Tomcat from 8080 to 80?

Question

I want to execute my web app as http://localhost.

Answer 1

Running the command below worked with. Tried changing server.xml and the conf file but both didn't work.

/sbin/iptables -A INPUT -i eth0 -p tcp --dport 80 -j ACCEPT

/sbin/iptables -A INPUT -i eth0 -p tcp --dport 8080 -j ACCEPT

/sbin/iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080
