HaProxy 2 Apache servers => modjk => 2 tomcat servers

Help!
1

Hi,

I have the following config :

Server A and Server B

On server A and B I have Apache 2.2 Tomcat 6, 7 and 8.

I use HAPROXY to redirect to Server A and Server B :443

backend web-tcp-backend
mode tcp

balance roundrobin

    balance leastconn
    stick-table type ip size 1m expire 12h
    stick on src
    option ssl-hello-chk
    server serverA 192.168.2.22:443 check
    server serverB 192.168.2.33:443 check

I use mod_jk to forward request to tomcat with worker loadbalance:

Setting the First Tomcat Server web1 tomcat7 inst1

worker.web1tomcat7inst1.port=8719
worker.web1tomcat7inst1.host=serverA
worker.web1tomcat7inst1.type=ajp13
worker.web1tomcat7inst1.lbfactor=50
worker.web1tomcat7inst1.socket_keepalive=1

Setting the Second Tomcat Server web2 tomcat7 inst1

worker.web2tomcat7inst1.port=8719
worker.web2tomcat7inst1.host=serverB
worker.web2tomcat7inst1.type=ajp13
worker.web2tomcat7inst1.lbfactor=50
worker.web2tomcat7inst1.socket_keepalive=1

Setting the Load Balancer Worker

worker.loadbalancertomcat7inst1.type=lb
worker.loadbalancertomcat7inst1.balance_workers=web1tomcat7inst1, web2tomcat7inst1
worker.loadbalancertomcat7inst1.sticky_session=1

My question is:

Is my config OK or should I use HAProxy to check : serverA:8719 and serverB:8719 or let mod_jk loadbalancer do the job.

Thanks!
