LOAD BALANCING WITH APACHE WEB SERVER (PART 1)

Overview

This article quickly provides steps to configure load balancer while setting up a clustered environment in a distributed network.
However, this should not be considered as a full and final configuration for a full-fledged production stable configuration. To make a production stable load balancing server, several configurations need to be done.

This is just an illustration of how the basic configuration can be carried out with limited resource availability.

Assumption

1. Server 1: Exposed a web service or open for web requests.
2. Server 2: Expose a web service that is open for web request and also hosts a apache load balancer
3. Server 1 and 2 are running on a separate IPs
4. HTTP Port on Server 1: 8091
5. HTTP Port on Server 2: 8091
6. Apache HTTPD server port: 8090 setup on Server 2

Prerequisites

1. Server 1 setup for hosting SOAP service exposed on mule server with following
URI: http://<>:8091/hello?wsdl
2. Server 2 setup for hosting SOAP service exposed on mule server with following
URI: http://<>:8091/hello?wsdl
3. Apache httpd server configured on Server 2

Sequence of operation

1. Create and run web service on Server 1
2. Create and run web service on Server 2
3. Install and configure HTTPD Server as LB instance
  a. Configure httpd-proxy-balance.conf
  b. Configure httpd.conf
4. Assert LB activity
