Steps to configure Apache HTTP Server Plug-In with Weblogic Server

Considering the Apache HTTP Server [Apache2.2] is already running as Windows service on port 8089 we shall continue to configure Apache HTTP Server Plug-In with Weblogic Server.

I am making use of Apache 2.2 and Weblogic 10.3 for this Post and demonstrating to access the Weblogic Console via Apache HTTP Server.

Steps to configure Apache HTTP Server Plug-In with Weblogic server

1. Identify the plug-in shared object file for your version of Apache in below table.

Apache Version	Regular Strength Encryption	128-bit Encryption
Standard Apache Version 2.0.x	mod_wl_20.so	mod_wl128_20.so
Standard Apache Version 2.2.x	mod_wl_22.so	mod_wl128_22.so

2. Verify that the WebLogic Server Apache HTTP Server Plug-In mod_so.c module is enabled.

The Apache HTTP Server Plug-In will be installed in your Apache installation as a Dynamic Shared Object (DSO). DSO support in Apache is based on module mod_so.c, which must be enabled before mod_wl_20.so is loaded. If you installed Apache HTTP Server using the script supplied by Apache, mod_so.c is already enabled. Verify that mod_so.c is enabled by executing the following command:

%APACHE_HOME%\bin\httpd.exe -l

-- Where APACHE_HOME is the directory containing your Apache installation

3. Copy the appropriate Weblogic Proxy plug-ins from Weblogic Installation to Apache installation.

Windows: %WEBLOGIC_HOME%\server\plugin\win\32\mod_wl_22.so to %APACHE_HOME%\modules\10.3\mod_wl_22.so

Solaris:  $WEBLOGIC_HOME/server/plugin/solaris/sparc/mod_wl_22.so to %APACHE_HOME%/modules/10.3/mod_wl_22.so

Note: To differentiate the version of Weblogic proxy plug-ins, create a directory named with Weblogic version under %APACHE_HOME%/modules

4. Install the Apache HTTP Server Plug-In module for Apache by adding the following line to your APACHE_HOME/conf/httpd.conf file manually:

#Weblogic Module 

LoadModule weblogic_module modules/mod_wl_20.so

5. Modify the below configuration and add it to the same APACHE_HOME/conf/httpd.conf to redirect calls to Weblogic instances as per your requirement. In my example below I am trying to access Weblogic console via Apache re-direction.

<IfModule mod_weblogic.c>
  WebLogicCluster     weblogicserver.com:7002
  Match Expression    *
  Debug                    ON
  WLLogFile               c:/tmp/global_proxy.log
  WLTempDir             "c:/myTemp"
  DebugConfigInfo     On
  KeepAliveEnabled     ON
  KeepAliveSecs         15
</IfModule>
<Location /console>
  SetHandler weblogic-handler
  PathTrim /console
</Location>

The Apache HTTP Server Plug-In recognizes the parameters listed in General Parameters for Web Server Plug-Ins. To modify the behavior of your Apache HTTP Server Plug-In, define these parameters: 

-- In a Location block, for parameters that apply to proxying by path, or 

-- In an IfModule block, for parameters that apply to proxying by MIME type  

6. Verify if the recently added configurations in the APACHE_HOME\conf\httpd.conf file is accurate with the following command:

%APACHE_HOME%\bin\httpd.exe -t 

The output of this command reports any errors in your httpd.conf file or returns:

Syntax OK 

7. Restart Apache HTTP Server.

8. Test the plug-in by opening a browser and setting the URL to the Apache Server + ":" + port + “/console”, which should bring up the default WebLogic Server HTML page, welcome file, or default servlet, as defined for the default Web Application on WebLogic Server. 
For example: 

http://apacheserver.com:8089/console

That's it.
