负载平衡Apache Httpd，Mod_Jk 32位，Tomcat 7，Windows 2008 R2

Question

Please need help in configuring the Load Balancer with Apache HTTPD 2.4 and Tomcat 7. I have seen many posts on this topic and managed to configure to an extent.

The strange problem i am facing is if I start 2 instances of tomcat and try to browse the APP URL, I get "This webpage is not available" . If I stop one instance, I am able browse the App. Apache HTTPD and Tomcat servers are running on the same machine.

workers.properties

worker.list=router,status
worker.worker1.port=8109
worker.worker1.host=172.16.0.79
worker.worker1.type=ajp13
worker.worker1.lbfactor=1
worker.worker1.local_worker=1
worker.worker1.sticky_session=0
worker.worker2.port=8209
worker.worker2.host=172.16.0.79
worker.worker2.type=ajp13
worker.worker2.lbfactor=1
worker.worker2.local_worker=0
worker.worker2.sticky_session=0

worker.router.type=lb
worker.router.balanced_workers=worker1,worker2
worker.router.local_worker_only=1

worker.status.type=status

Httpd.conf

<IfModule mod_proxy.c>
<IfModule mod_proxy_ajp.c>

Please correct me if any issues in configuration. Thanks in advance.

Answer 1

Please send your virtualhost mapping also.

I think that httpd is not deciding to whom ajp connector, it should connect.

For simplicity take 2 different router

worker.list=router,router1,status
worker.worker1.port=8109
worker.worker1.host=172.16.0.79
worker.worker1.type=ajp13
worker.worker1.lbfactor=1
worker.worker1.local_worker=1
worker.worker1.sticky_session=0
worker.worker2.port=8209
worker.worker2.host=172.16.0.79
worker.worker2.type=ajp13
worker.worker2.lbfactor=1
worker.worker2.local_worker=0
worker.worker2.sticky_session=0

worker.router.type=lb
worker.router.balanced_workers=worker1
worker.router.local_worker_only=1
worker.router1.type=lb
worker.router1.balanced_workers=worker2
worker.router1.local_worker_only=1

worker.status.type=status
ex:- jkMount  /xyz/* router
jkMount  /abc/* router1

you can also make 2 virtualhost mapping for different domain or subdomain
