Apache, Tomcat, JK Configuration Example

Example of worker.properties:

worker.list=myWorker,yourWorker

worker.myWorker.port=7505
worker.myWorker.host=my.host.com
worker.myWorker.type=ajp13
worker.myWorker.secret=secretword

worker.yourWorker.port=7505
worker.yourWorker.host=your.host.com
worker.yourWorker.type=ajp13
worker.yourWorker.secret=yoursecretword

Example of httpd.conf

#
## httpd.conf -- Apache HTTP server main configuration file
##
## This is an attempt to make a minimal, generic and yet useful configuration
##
## For INTERNAL UBS IB users (read the comments #@).
## - See complete original file ./conf/original/httpd.conf with syntax comments.
## - More documentation: http://goto/apache and http://httpd.apache.org
##
## For EXTERNAL Hosted web servers, you MUST read and change all sections marked #@SECURITY
#
