This tutorial describes the installation of a clustered web, email, database and DNS server to be used for redundancy, high availability and load balancing on Debian 6 with the ISPConfig 3 control panel.

You might know that beginning with MySQL 5.1.24, support for the NDBCLUSTER storage engine was removed from the standard MySQL server binaries built by MySQL. Therefore, here I'm using MySQL Cluster edition instead of MySQL Community edition.

LTSP-Cluster can scale up to several thousands thin clients providing an enterprise-class infrastructure (load balancing, high availability, central management, monitoring) as well as large-scale remote access (Citrix like) for thousands of users at a fraction of the cost of a proprietary equivalent using open source technologies.

This tutorial describes the installation of a clustered web, email, database and DNS server to be used for redundancy, high availability and load balancing on Debian 5 with the ISPConfig 3 control panel. GlusterFS will be used to mirror the data between the servers and ISPConfig for mirroring the configuration files.

This tutorial shows how to set up a two-node Apache web server cluster that provides high-availability. In front of the Apache cluster we create a load balancer that splits up incoming requests between the two Apache nodes. Because we do not want the load balancer to become another "Single Point Of Failure", we must provide high-availability for the load balancer, too.

This guide attempts to provide a Xen based test environment where you can practice setting up a two node cluster (cluster setup itself is not discussed here - I'm merely giving you what you need to set it up).

So, what is MySQL Cluster? It is a database solution which tries to solve high availability issues by using multiple synchronous masters (for the lack of a better phrase) in a shared-nothing environment. In order to solve a lot of the latency issues associated with multiple masters, it keeps all the indexed data in memory to enable fast processing of the data.

Now that I am done with the implementation of RHE Cluster with GFS2, I now need to setup monitoring. As you all know, monitoring is a vital part of any environment. Even though we have a cluster of nodes setup, we still need to be aware of what is happening. I created two new commands. The first command is to emulate clustat, but through python and SNMP.
