Thanks Anam, but we are looking at to use mod proxy for Apache/Tomcat
Communication and session persistence. Can it be done using our requirement?


Thank you,

I would recommend HAProxy as a load balancer in your PHP + JSP application
environment. It will work as follows:


1. First HAProxy will accept client request.

2. It will forward those requests to two machines via round robin 

3. Each WebServer must use mod_jk as a connector (module) for Apache/Tomcat
communication and session persistence.

4. HAproxy also perform health checking for two servers.

Subject: [users@httpd] Apache + Tomcat Load Balancing




We have requirement for to load balance our PHP + JSP application. I need to
know that how can I load balance 2 Apache web Servers and 2 Tomcat Servers,
1st Web Server + Tomcat on 1st machine and 2nd Web Server + Tomcat on 2nd
machine. We want to use Proxy Load Balancer for Apache to tomcat

If we use single Apache Web Server and 2 tomcat instances on different
machines, it seems to be working and sharing session fine, but when we add
2nd apache web server to have fail over for PHP too, tomcat stops
replicating session? If anyone is running such type of setup then kindly do
let me know what could be the issues or anything missing. I am using Apache
WebServer as a load balancer for both Apache too.


Apache Webserver
