Introduction

This is a supplementary article for the article Server Clustering Guide. Instead of running Apache 2 as the load balancer on a Linux-based system, we are going to use Windows-based Apache 2 instead. In this example, we are going to use Apache Lounge.

Deployment Guide

Download Apache Lounge

  1. Download Apache Lounge from http://www.apachelounge.com/download/
  2. Extract to your preferred location.

Server Clustering Guide

Please follow the steps in Server Clustering Guide except for Configure Load Balancer section.

Configure Load Balancer

Edit the file \Apache24\conf\httpd.conf.

Uncomment these lines to enable the necessary modules.

LoadModule headers_module modules/mod_headers.so
LoadModule lbmethod_byrequests_module modules/mod_lbmethod_byrequests.so
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule slotmem_shm_module modules/mod_slotmem_shm.so


Configure the variable SRVROOT to point to your working path.


Define SRVROOT "c:/Users/cat/Apache24"

Append these to the end of the file.

<VirtualHost *>
    ServerAdmin support@example.com
    ErrorLog "C:\Users\cat\Apache24\joget\logs\jwsite-error.log"
    CustomLog "C:\Users\cat\Apache24\joget\logs\jwsite-access.log" combined
    DirectoryIndex index.html index.htm
    <Proxy balancer://wscluster>
        BalancerMember ws://server1:8080 route=node01
        BalancerMember ws://server2:9090 route=node02
        Require all granted
    </Proxy>
    ProxyPass /jw/web/applog balancer://wscluster/jw/web/applog stickysession=JSESSIONID|jsessionid
    ProxyPassReverse /jw/web/applog balancer://wscluster/jw/web/applog
    <Proxy balancer://cluster>
        BalancerMember http://server1:8080 route=node01
        BalancerMember http://server2:9090 route=node02
        Require all granted
    </Proxy>
    ProxyPass /jw balancer://cluster/jw stickysession=JSESSIONID|jsessionid
    ProxyPassReverse /jw balancer://cluster/jw
    ProxyPreserveHost On
</VirtualHost>

Create a new folder at this location to host the log files.

Start the Apache server

httpd.exe

Once you have verified that it is working, you may consider to set it up as a Windows service, please see https://httpd.apache.org/docs/2.4/platform/windows.html#winsvc.
