Configure the Apache HTTP Server Plug-In for your WebLogic Server cluster

Suppose, you have in your WLS domain 3 clustered managed servers and you want to install and configure the Apache plug-in for your cluster.
I executed this demo on an Oracle Linux 5.7 64-bit system.
To achieve this, you'll have to execute these steps:
(1) Install WLS + configure domain (admin server + managed servers + cluster) + install the necessary rpm's + define the correct properties in the file "/etc/hosts".

(2) Download the latest Apache installer for your OS (http://httpd.apache.org/download.cgi).

(3) Copy the file to the desired directory and unzip the file

(4) Configure Apache

(5) Make Apache

(6) Make Install Apache

(7) Copy the mod_wl_22.so file to the apache directory structure

(8) Open the file /opt/apache/conf/httpd.conf and edit some general parameters (like ServerName, User, Group etc)

(9) In the same file, load the mod_wl_22.so into Apache and define the properties of your WLS domain

(10) Log in as root to start or shut down Apache

P.S.: On Oracle Linux you can of course install Apache through yum.
