Apache+jboss Cluster load Balancing based on reverse proxy (reprint)

Assume that the three machine IP is 172.29.128.100, 172.29.128.101, 172.29.128.102, all 32Bit Windows XP system, respectively installed Apache2.2, Jboss-4.2.3.ga, Jboss-4.2.3.ga.

The schema that will be deployed is as follows:

Apache (172.29.128.100)

JBoss Cluster

Configure load Balancing

Modify the Apache httpd.conf and release the comments before the following modules:

LoadModule Proxy_module modules/mod_proxy.so

LoadModule Proxy_ajp_module modules/mod_proxy_ajp.so

LoadModule Proxy_balancer_module modules/mod_proxy_balancer.so

LoadModule Proxy_connect_module modules/mod_proxy_connect.so

LoadModule proxy_ftp_module modules/mod_proxy_ftp.so LoadModule proxy_http_module modules/mod_proxy_http.so

Add in httpd.conf:

Proxyrequests off
