The configuration of Tomcat web server should be performed in addition to the workers configuration. The default port is 8009, but it can be changed on both sides: in server.xml on the Tomcat side and in the file worker.properties on the Apache HTTPD server side (look for 8009): When you will configure mod_jk on Apache HTTPD server using the following link you will see the connection: So if you have both HTTPD and Tomcat in the same machine, they fit nicely, as the ports used are different by default:ġ) Apache HTTPD server and the Tomcat web server can be connected using The Apache Tomcat Connector - mod_jk Keep in mind, HTTPD keeps care of his ports, Tomcat of his own ports and a port can be in listen only from a single application at a time. And as for your configuration, if you setup Tomcat to use HTTP S he will redirect requests in HTTP to the port configured. In Tomcat language those are connectors (as opposed to Listen in HTTPD). You can configure Tomcat for the ports in server.xml. You can configure the ports for HTTPS using Listen directives in it's configuration file, nf or files included from it.

Tomcat listens on port 8080 for HTTP, port 8443 for https and port 8009 for AJP. Now being more serious, by default, HTTPD listens on ports 80 for HTTP and port 443 for HTTPS. So HTTPD knows that there are two translators that can help him speak AJP with Tomcat, mod_jk ( ) and mod_proxy_ajp ( ). Sometimes costumers ask for stuff not present in the shop but when he knows Tomcat has it he calls Tomcat and asks him to bring the things.For speaking with Tomcat HTTPD can use international languages, HTTP and HTTP S, but often Tomcat is more happy to speak his own language, AJP.

The first two are the same as for Tomcat but HTTPD is not that eccentric prefering to use the normal agreed numbers, 80 for HTTP and 443 for HTTPS.

HTTPD has only two phones for recieving calls By International Common Law, it's port 8009. The third Tomcat's phone he uses it to recieve calls only from people that speak his own language, AJP (He lives in Java Application Server Country). By international agreements this port is 443, but as we said Tomcat is eccentric, he chooses for this port 8443. It happens that Tomcat being a bit eccentric preferes 8080 by default, so you can speak him HTTP at port 8080 by default.Īnother phone for recieving calls from international VIP people, which want to be ultra sure they are speaking with Tomcat and nobody can listen their call, so they speak the previous international language but switching words (encryption, HTTP S).

This phone has an international agreed subnumber (port) which is 80, but can be any number. One for recieving international calls in which he speaks the langauage spoken by most people in the (informatic) world, HTTP. Tomcat has three phones for recieving calls: In server.xml what is the purpose of redirectPort 8443?Ĭonsider Apache HTTPD and Apache Tomcat two friends (I'll call them in short HTTPD and Tomcat).Įach of them has means of comunicating with other people, let's say by mobile phone and lineland phone or IM. I think after Tomcat is started this port is available. But this is the port mentioned at apache2/conf/workers.properties. What is starting this AJP connector (Tomcat or Apache)?īecause even when Apache is started I am NOT seeing a socket listening at 8009. How is the 8009 port interrelated with the Apache and Tomcat ports? Does this mean how the requests are interchanged between the connector, Apache, Tomcat, etc.? (AJP connector is used for cases where you wish to invisibly integrate Tomcat 4 into an existing (or new) Apache installation) There is one more Connector port='8009' using the 'AJP/1.3' protocol.80 ports are used by Tomcat for HTTP and HTTPS requests respectively.80 and 443 ports are used by Apache for HTTP and HTTPS requests respectively.Through netstat and TOMCAT/conf/server.xml I understand that: I have few questions regarding the Apache HTTPD server and the Tomcat web server port configurations.

Apache tomcat error these ports use
