This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses.

This release combines the latest technologies along with many improvements to bring users the premier collection of Free Software for home and professional use. Special thanks to the KDE Quality Team for managing a comprehensive testing program for this release. Their work greatly assisted developers and played a key role in maintaining quality and stability.

This tutorial shows how to combine four single storage servers (running Ubuntu 12.10) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network.

This tutorial shows how to set up a standalone storage server on Debian 6.0, using GlusterFS and SAMBA, and custom scripts and settings to make life easier. The SAMBA share will reside on a GlusterFS share which consists out of two storage nodes for high-availability.

LAMP is short for Linux, Apache, MySQL, PHP. This tutorial shows how you can install an Apache2 webserver on a Fedora 18 server with PHP5 support (mod_php) and MySQL support.

This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 12.10) 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 (Ubuntu 12.10 as well) will be able to access the storage as if it was a local filesystem.

This howto describes a shared local git server setup for a small team. This is a repository layout that is familiar to anyone used to working with a traditional version control system. One of the tutorial objectives is to show detailed steps to prepare the server and publish the code on a public service like Github, Gitorius et. al.

mylvmbackup is a Perl script for quickly creating MySQL backups. It uses LVM's snapshot feature to do so. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. This article shows how to use it on an Ubuntu 12.10 server.
