This document describes how to configure mod_jk for Apache / Tomcat on SLES 11 SP2.
NOTE:  mod_proxy, in conjunction with proxy ajp is the recommended approach for linking the Apache Web Server to Tomcat on Open Enterprise Server 11, but there are cases in which mod_jk needs to be used.  Even though it is NOT recommended, the steps outlined here for SLES11, are similar on an OES11 server.


This document outlines the steps needed to get mod_jk working with Apache and Tomcat on SLES11
1.) From YaST, install the mod_jk package for Tomcat, located in software, search on mod_jk
2.) In /etc/sysconfig/apache2 add JK module to APACHE_MODULES, it may go at the end of the line as such:
APACHE_MODULES="... ... ... ... ...jk"
3.) Create the following directory as the root user /etc/apache2/mod_jk/  
4.) Create the file /etc/apache2/mod_jk/mod_jk.conf  and add the following lines:
Add the following lines:
JkLogFile                       /var/log/apache2/mod_jk.log
JkWorkersFile           /etc/apache2/mod_jk/
JkShmFile                       /etc/apache2/mod_jk/mod_jk.shm
# Set the jk log level [debug/error/info]
JkLogLevel                      info
# Select the timestamp log format
JkLogStampFormat        "[%a %b %d %H:%M:%S %Y] "
# JK mount
JkMount /sample worker1
JkMount /sample/* worker1
5. ) Create the file/etc/apache2/mod_jk/ 
Add the following lines:
6.) Create the file: /var/log/apache2/mod_jk.log 
7.) Modify /etc/apache2/httpd.conf  to include the mod_jk.conf
Include /etc/apache2/mod_jk/mod_jk.conf  (Note: do NOT include the file, mod_jk.conf points at it, and will use it.  Trying to include it with the Apache config scripts will cause Apache to fail on loading)
8.) Run the rcapache2 restart command.

Additional Information

If a sample webapp (i.e. sample.war from the Apache Software Foundation) is being used, it can be placed here:  srv/tomcat6/webapps
Note: If the webapp being run through tomcat needs to be accessed via HTTPS on the Apache side, add the JkMount statements to the appropriate vhost file in /etc/apache2/vhosts.d just above the </VirtualHost> entry.
