When we need change the port, most of the time, it just need edit server.xml <pre> <Connector port=“8080” protocol=“HTTP/1.1” connectioTimeout=“20000” URIEncoding=“UTF-8”
redirectPort="8443" />
</pre>
But when I want to change it to 80, the tomcat can't start successfully. The tomcat doesn't support the port lower than 1024, so it need do some special work
vim /etc/default/tomcat6 AUTHBIND=yes
But this also not work on my vps, maybe the memory is not enough.
So the last solution is redirect to request on port 80 to 8080
sudo /sbin/iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
Horray, then it works.
