Question

I am trying to use mod_proxy with httpd and tomcat. If I leave Tomcat ajp to run on 8009 in the server.xml of tomcat and in the httpd.conf of Apache httpd, everything works great, but once I change it to anything else and restart them both it does not work. I tried 8109,8209 and 8019, but the only thing that works is 8009.

Below is my setup that works:

<Proxy balancer://testcluster stickysession=JSESSIONID>
BalancerMember ajp://127.0.0.1:8009 min=10 max=100 route=node2 loadfactor=1
</Proxy>

ProxyPass /examples balancer://testcluster/examples

<Location /balancer-manager>
SetHandler balancer-manager
AuthType Basic
AuthName "Balancer Manager"
AuthUserFile "/etc/httpd/conf/.htpasswd"
Require valid-user
</Location>

If I change the port to anything in here, and the server.xml of Tomcat it does not work, but I can telnet the port so I know its up.

Below are the other libs settings I have:

It was a issue with Scientific Linux release 6.2 I had to tell it to stop blocking the port by doing the following command

setenforce 0

it works then.
