Create /etc/httpd/conf/workers.properties

worker.list=worker1, worker2, loadbalancer, loadbalancerSSL, status

# Set properties for worker1 (ajp13)
worker.worker1.type=ajp13
worker.worker1.host=192.168.1.21

#worker.worker2.socket_timeout=10

# Set properties for worker(lb) which use worker1 and worker2
worker.loadbalancer.type=lb
worker.loadbalancer.sticky_session=1
worker.loadbalancer.balance_workers=worker2,worker1

worker.loadbalancerSSL.type=lb
worker.loadbalancerSSL.sticky_session=1
worker.loadbalancerSSL.balance_workers=worker2,worker1

# Status worker for managing load balancer
worker.status.type=status

Create file /etc/httpd/conf/uriworkermap.properties
