Server Monitoring With munin And monit On Debian Lenny
======================================================

In this article I will describe how you can monitor your Debian Lenny server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.

Fully Utilizing Your X-Core CPU
===============================

Almost all systems sold nowadays have at least a dual-core CPU, even triple- or quad-cores are getting cheaper and getting standard in the near future. But how to utilize your shiny x-core to it's full potential, with applications that are only utilizing one core ? With Linux, which has strong multitasking capabilities as all unixoid operating systems, there is an easy possibility to parallelize tasks which are normally only using one core of an x-core CPU.

High-Availability Storage With GlusterFS On Fedora 12 - Automatic File Replication (Mirror) Across Two Storage Servers
======================================================================================================================

This tutorial shows how to set up a high-availability storage with two storage servers (Fedora 12) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Fedora 12 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Distributed Storage Across Four Storage Nodes With GlusterFS On Fedora 12
=========================================================================

This tutorial shows how to combine four single storage servers (running Fedora 12) to one large storage server (distributed storage) with GlusterFS. The client system (Fedora 12 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Installing Lighttpd With PHP5 And MySQL Support On Fedora 12
============================================================

Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on a Fedora 12 server with PHP5 support (through FastCGI) and MySQL support.

Using WebDAV With ISPConfig 3 On Ubuntu 9.10
============================================

This guide explains how to set up and use WebDAV on a web site created with ISPConfig 3 on an Ubuntu 9.10 server. WebDAV stands for Web-based Distributed Authoring and Versioning and is a set of extensions to the HTTP protocol that allow users to directly edit files on the Apache server so that they do not need to be downloaded/uploaded via FTP. Of course, WebDAV can also be used to upload and download files.

Changing From SquirrelMail To RoundCube On Your ISPConfig3 Server
=================================================================

This tutorial has been created for those who have installed The Perfect Server - CentOS 5.4 x86_64 [ISPConfig 3] and do not like SquirrelMail as webmail client. Here's a guide to replace SquirrelMail with RoundCube, which is more visually attractive and easier to manage for our clients.
