it's part of mod_jk as I can assume that you have got mod_jk loaded and installed, working correctly for one server I shall begin ...
In your workers.properties you will find an entry titled worker.list this will probably look like worker.list=ajp13 You will then find the definition of ajp13 looking something like ... worker.ajp13.port=8009 worker.ajp13.host=localhost worker.ajp13.type=ajp13 worker.ajp13.lbfactor=1 The section of loadbalancer will look like ... worker.loadbalancer.type=lb worker.loadbalancer.balanced_workers=ajp13, ajp12 Now... Let us assume that you have 3 servers and they are all the same spec. So you want to balance the load evenly.. ( I am also assuming that you only have one apache server.) ie your machines looks like : +------+ |Apache| +------+ | +--------+---------+ | | | +-----+ +-----+ +-----+ | TC1 | | TC2 | | TC3 | +-----+ +-----+ +-----+ You need to define entries for your 3 tomcat servers... ( change the IP's to match yours..) worker.TC1.port=8009 worker.TC1.host=192.168.10.1 worker.TC1.type=ajp13 worker.TC1.lbfactor=1 worker.TC2.port=8009 worker.TC2.host=192.168.10.2 worker.TC2.type=ajp13 worker.TC2.lbfactor=1 worker.TC3.port=8009 worker.TC3.host=192.168.10.3 worker.TC3.type=ajp13 worker.TC3.lbfactor=1 change these to match the above : worker.loadbalancer.balanced_workers=TC1,TC2,TC3 worker.list=loadbalancer And Bingo you have a working loadbalanced trio of Tomcat servers. If you have 3 apache servers ie like +-----+ +-----+ +-----+ | A 1 | | A 2 | | A 3 | +-----+ +-----+ +-----+ | | | +--------+---------+ | | +--------+---------+ | | | +-----+ +-----+ +-----+ | TC1 | | TC2 | | TC3 | +-----+ +-----+ +-----+ you just need to setup the same workers.properties on all the apache servers...
