Best Practise for using apache mod_jk and F5 version 9.4.3

Given the flexibility of iRules, iControl and even just the out of the box features of the BIG-IP, there's an incredible amount you can do with the systems. However, it would be much easier to answer your question if you gave some specifics. What is it you're trying to do? If you tell us more specifically what you're trying to accomplish, we'll likely be able to tell you whether or not it's possible via the BIG-IP.

 

 

Thanks!

Colin,

 

Thanks for your quick response. What I am trying to achieve to is replace mod_jk (software loadbalancer) with F5 (hardware loadbalancer) to achieve round robin load balancing and fail over.

 

The mod_jk files contain the following files that perform round robin load balancing and fail over.

 

1. workers.properties file

 

2. uriworkermap.properties file

 

Here is the lay out for workers.properties file

 

 

 

workers.properties

 

 

 

In Unix, we use forward slashes:

 

ps=/

 

 

Define list of workers that will be used

 

for mapping requests

 

worker.list=loadbalancer,status

 

 

------------------------

 

First tomcat server

 

------------------------

 

worker.tomcatAUS1.port=41009

 

worker.tomcatAUS1.host=170.13.57.56

 

worker.tomcatAUS1.type=ajp13

 

worker.tomcatAUS1.lbfactor=1

 

worker.tomcatAUS1.cachesize=100

 

 

------------------------

 

Second tomcat server

 

------------------------

 

worker.tomcatAUS2.port=41009

 

worker.tomcatAUS2.host=170.13.57.57

 

worker.tomcatAUS2.type=ajp13

 

worker.tomcatAUS2.lbfactor=1

 

worker.tomcatAUS2.cachesize=100

 

 

Load-balancing behaviour

 

worker.loadbalancer.type=lb

 

worker.loadbalancer.balance_workers=tomcatAUS1,tomcatAUS2

 

worker.loadbalancer.sticky_session=1

 

 

Status worker for managing load balancer

 

worker.status.type=status

 

 

The purpose of this file is to load balancing web trafffic between two tomcats node using round robin with session affinity.

 

 

uriworkermap.properties look like this:

 

Simple worker configuration file

 

 

Mount the Servlet context to the ajp13 worker

 

/jmx-console=loadbalancer

 

/jmx-console/*=loadbalancer

 

 

/web-console=loadbalancer

 

/web-console/*=loadbalancer

 

 

/fnmcreditmanager=loadbalancer

 

/fnmcreditmanager/*=loadbalancer

 

 

/ausws=loadbalancer

 

/ausws/*=loadbalancer

 

 

/amnetdtd=loadbalancer

 

/amnetdtd/*=loadbalancer

 

 

/iqueh-web=loadbalancer

 

/iqueh-web/*=loadbalancer

 

 

 

/iquea-web=loadbalancer

 

/iquea-web/*=loadbalancer

 

 

This file is to do url redirect.

 

 

These two files are the key files for mod_jk along with mod_jk.conf.

 

 

My question is if I plan to use F5 to replace mod_jk in front of apache, is there any equivant files that I can modify for F5?

 

 

Thanks,

 

 

Bill

I would be interested in knowing this since I'm about to embark on this very same voyage. My company is looking to deploy 2 Apache/mod_jk servers and if I can leverage the BIGIP F5 hardware to perform the very same functions, I can convince management to conserve resource and have the F5 do all the dirty work.
