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

Question

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

Answer 1

I tried changing the port from 8080 to 80 in the server.xml but it didn't work for me. Then I found alternative, update the iptables which i'm sure there is an impact on performance.

I use the following commands:

sudo /sbin/iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
sudo /sbin/service iptables save
