Hi List,
I am newbee to set up the HAProxy. I wanted to set up the HAProxy between
the httpd apache web server & tomcat apps server as a load balancer.
Currently we are using sticky session for the load balancing. However,
HAProxy, we can use the round robin method to balance all the request
coming from the web server to the apps server and properly utilizing all
the apps. server in terms of request handling and load balancing. As of now
sometimes one apps server is heavily loaded while the other one is not
serving a single request or very less request handling.
I wanted to set up with one httpd web server & 3 tomcat apps server
Example Network
192.168.1.68: Web server
192.168.1.45: App server 1
192.168.1.46: App server 1
192.168.1.47: App server 1
192.168.1.50: HAProxy host
Will below config works. Kindly add your inputs.
