Introduction

This guide is a brief explanation on getting a two node director/real server setup going using LVS and keepalived.

This is an adaptation of the information at Ultra Monkey: Streamline High Availablility and Load Balancing to work with keepalived.

It is primarily targeted at RHEL3/4 (RedHat Enterprise Linux).

Goals

Setup a two node LVS cluster with Apache as the virtualised services, with both nodes operating as both directors and real servers.
Setup healthchecking of services (httpd).
Setup lvs-syncing of connections (ipvsadm sync daemon).

Knowledge Required

Understanding of Layer 3 load balancing.
Understanding of Linux LVS.
Understanding of Apache configuration.

Components Required

Base installation of RHEL3/4.
RPM Packages for httpd.
RPM Packages for keepalived.
RPM Packages for ipvsadm.
