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).
Goal
Setup a two node LVS cluster with Apache as the virtualised services, with only two 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
