Apache | Integrating with Tomcat (mod_proxy_ajp) | Stop Port 8080 and Check the AJP/1.3 Protocol

Tags:

To change access so it goes through Apache, prevent direct connections to Tomcat, which is currently running on port 8080.

For the configuration, open server.xml in {Tomcat installation directory}/conf with a text editor. Search for 8080, and you should find the following.

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

Comment out this entire section.

<!--
    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
-->

Now it is no longer possible to connect to Tomcat on port 8080.

After completing the configuration, restart Tomcat and try accessing http://localhost:8080/hello/helloworld in a browser.

Stop port 8080

Then search server.xml for the following content. It should appear when you search for AJP.

    <!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

Apache will connect to Tomcat on port 8009 using the AJP/1.3 protocol.
