MySQL Master/Master replication will be used to replicate the MySQL client databases between the servers and Unison will be used to Sync the /var/www (websites) and /var/vmail (email account data) folders. falko Thu, 16 Feb 2012 11:54:34 GMT http://www.howtoforge.com/installing-and-configuring-openfiler-with-drbd-and-heartbeat Openfiler is a high performance operating system tailored for use as a SAN/NAS appliance. This configuration will enable two Openfiler appliances to work in an active/passive high availability scenario. falko Sun, 26 Oct 2008 13:31:26 GMT http://www.howtoforge.com/installing-the-galera-iworx-cluster This document describes the installation of the Galera/Interworx cluster. This cluster provides the default Load Balancing that is available within Interworx, and additionally MySQL loadbalancing through MySQL Galera Clustering. falko Thu, 27 Jun 2013 10:36:13 GMT http://www.howtoforge.com/setting-up-a-high-availability-load-balancer-with-haproxy-keepalived-on-debian-lenny This article explains how to set up a two-node load balancer in an active/passive configuration with HAProxy and keepalived on Debian Lenny. The load balancer sits between the user and two (or more) backend Apache web servers that hold the same content. Not only does the load balancer distribute the requests to the two backend Apache servers, it also checks the health of the backend servers. If one of them is down, all requests will automatically be redirected to the remaining backend server. In addition to that, the two load balancer nodes monitor each other using keepalived, and if the master fails, the slave becomes the master, which means the users will not notice any disruption of the service. HAProxy is session-aware, which means you can use it with a falko Tue, 16 Jun 2009 10:34:14 GMT http://www.howtoforge.com/the-perfect-load-balanced-and-high-availability-web-cluster-with-2-servers-running-xen-on-ubuntu-8.04-hardy-heron In this howto we will build a load-balanced and high-availability web cluster on 2 real servers with Xen, hearbeat and ldirectord. The cluster will do http, mail, DNS, MySQL database and will be completely monitored. This is currently used on a production server with a couple of websites. The goal of this tutorial is to achieve load balancing & high availability with as few real servers as possible and of course, with open-source software. More servers means more hardware & hosting cost. falko Sun, 12 Oct 2008 12:44:58 GMT
