How to configure Tomcat to only listen to 127.0.0.1?

Question

The environment is Ubuntu 10.04.1 LTS running Tomcat 6 and Apache 2.2 from the repos. Apache is configured to proxy requests to Tomcat, so I really want to turn off Tomcat listening to requests on external IP addresses.

I found out how to change the port number in /etc/tomcat6/server.xml with the Connector tag, but this isn't what I need.

Answer 1

Inside the Service tag change:

<Connector port="8080" protocol="HTTP/1.1"
...

to:

<Connector address="127.0.0.1" port="8080" protocol="HTTP/1.1"
...

Answer 2

The default in a Tomcat 6 installation is to listen to localhost only.
