Intergating apache and tomcat with jk_mod.so

bittus · 08-26-2011, 01:14 AM

I am trying to integrate Apache 2.2.8 and Tomcat 6.0.33

The steps that I have done.

Downloaded and compiled mod_jk
Edited the worker.properties file like :

worker.list=worker1
worker.worker1.type=ajp13
worker.worker1.host=localhost
worker.worker1.port=8009
Edited the httpd.conf
LoadModule jk_module /usr/local/apache2/modules/mod_jk.so
JkWorkersFile /etc/httpd/conf/workers.properties
JkShmFile /var/log/httpd/mod_jk.shm
JkLogFile /var/log/httpd/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkMount /examples/* worker1

As per the configuration, if I try http://localhost/examples, I should be getting the tomcat apllication. Instead, I get a message "File does not exist: /var/www/html/ABC/examples" in the httpd error_log.

Anyone, any clue on this

Shouldn't that be /var/www/html/examples

What is your distro?
I guess from the docroot path, that it's RHEL based. If that's the case I would suspect a selinux permissions problem.

Your are right. It's RHEL based.
Do you have any idea of the required SElinux context ?

Hi,

I'm not a rhel fan, so I know little about selinux. Anyway you should try to disable it temporarily and see if that's the case. Run

Code:

setenforce 0

and check.
If it's selinux, relabel the docroot as in the example here.

@bathory,
Thanks for the feedback and sorry for the late update.
I was wondering how I missed, SElinux is disabled on the server. So that should not be the issue

I will brief my requirement again.
Now, in order to reach the tomcat service we should type in http://192.168.1.102:4455/examples/m...1034&room=chat
I would like to access the service by just typing in http://www.mydomain.com/tc/examples/...1034&room=chat

Any suggestions are welcome.

I would also like to know, if mod_rewrite will help !!!

Hi,

You can use mod_proxy or mod_proxy ajp for this.
Take a look at this howto for details.
