Can you provide detailed steps for setting up a load balancer for a jboss cluster using mod_proxy_ajp module of apache HTTP Server

There are something to supp. for my case,

My webapps contain some browser redirect (HTTP return code302), and I find that the 302 sometime fail to “stick” to the same machine. To soft this, append “nofailover=On” to the ProxyPass command, and add also the ProxyPassRequest, it work find for the 302 redirect.

here is my example,

ProxyPass /gateway2/ balancer://ajpCluster/gateway2/ stickysession=JSESSIONID nofailover=On ProxyPassReverse /gateway2/ balancer://ajpCluster/gateway2/

How can I implement mod_proxy_ajp with regular expresion, without using rewite rules?

My configuration is two Tomcat servers serving the web site on port 80. / is the application root.

I tried this:

BalancerMember ajp://10.10.81.154:80 route=LB1 BalancerMember ajp://10.10.81.155:80 route=LB2

ProxyPass balancer://myCluster/myApp stickysession=JSESSIONID



    SetHandler balancer-manager

but when I deleted “myApp” it did not work

I had the same problem. My solution was to deploy on my production servers as ‘production’, thus ajp://prodserver01:8009/production/index.jsp and ajp://prodserver02:8009/production/index.jsp and the test servers as ‘test’, thus ajp://testserver01/test/index.jsp and ajp://testserver01/test/index.jsp.

The only other solutions I can think of are: 1) Get Apache to rewrite the Urls in the pages that your application returns. This is probably not feasible. 2) Be very careful about creating URLs in your application. Everything should be relative to ‘app’, which means you cannot start any URLs with ‘/’.

Did you have answer for your question? I am having the same issue here and very much interested in knowing the solution.

Thanks Yan

I saw your post about using the new mod_proxy_ajp instead of mod_jk and it works great. Now I am trying to use apache for balance two java web applications (each one in diferent clusters), the two are the same but in different phases, one for developing and one for testing. the first is in devserver:5000/app/home.jsp and devserver2:5001/app/home.jsp and the otrher is in testserver:5000/app/home.jsp and testserver:5001/app/home.jsp

and I want the apache server be the entry point for both, something like: http://balanceServer/dev/app/home.jsp and http://balanceServer/test/app/home.jsp and depending on the “dev” ot “test” prefix redirects to each cluster.

My problem is how to rewrite the url links comming from the cluster to insert them the “dev” or “test”? because right now it is sending me to the correct cluster but when trying a submit, the browser resolves to balanceServer/app/submitionpage.jsp, do you have idea?

Thank you, this is the first time I use Apache.
