Apache fails to talk to Tomcat

[Barry Clarkson <Ba...@kcom.com>]

Hi all,

I have just installed Tomcat with mod_jk on the same machine and performed
the necessary configuration with workers.properties, server.xml etc.  I can
connect to the port directly with Tomcat (http://<ip address>:8090/dir) but
if I omit the port and go through Apache the jk.log indicates that "Tomcat
has forced a connection close for socket 17", "Tomcat is down or refused
connection. No response has been sent to the client (yet)" etc...

Any help would be greatly appreciated!

We're running:

Red Hat Linux AS 4
Mod_jk 1.2.18 (binary distribution mod_jk-apache-2.0.49-linux-i686.so)
Apache 2.0.52

workers.properties:

# workers.properties

# Define a worker
worker.list=ajp13

# Set the workers properties
worker.ajp13.port=8091
worker.ajp13.host=127.0.0.1
worker.ajp13.type=ajp13
worker.ajp13.cachesize=10
worker.ajp13.cache_timeout=600
worker.ajp13.socket_keepalive=1
worker.ajp13.socket_timeout=300
worker.ajp13.lbfactor=1

server.xml:

    <!-- Define an AJP 1.3 Connector on port 8091 -->
    <Connector className="org.apache.ajp.tomcat4.Ajp13Connector"
               port="8091" minProcessors="5" maxProcessors="75"
               acceptCount="10" debug="1"/>

Cheers,

Barry

Remove this directive.
I suppose you are using prefork mpm?

What is the number of StartServers in httpd.conf?
It might be its a higher number then maxProcessors, so
you will get connection refused errors.
