This document describes how to install and set up ownCloud on CentOS 6.2 on an nginx web server and php-fpm with postgreSQL database as backend. For other distributions there might be minor changes as to the software prerequisites installation procedures. This guide will not only help install the product, but also understand why certain points are done the way they are done.

This tutorial shows how to set up a high-availability storage with two storage servers (Debian Squeeze) 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 (Debian Squeeze 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.

This tutorial shows how you can set up a Linux Mint 13 (Maya) desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge.

This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.

Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on an Ubuntu 12.04 server with PHP5 support (through PHP-FPM) and MySQL support. PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites. I use PHP-FPM in this tutorial instead of Lighttpd's spawn-fcgi.

This tutorial describes how you can install Apache2 with mod_fcgid and PHP5 on CentOS 6.2. mod_fcgid is a compatible alternative to the older mod_fastcgi. It lets you execute PHP scripts with the permissions of their owners instead of the Apache user.

Nginx (pronounced "engine x") is a free, open-source, high-performance HTTP server. Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption. This tutorial shows how you can install Nginx on an Ubuntu 12.04 LTS server with PHP5 support (through PHP-FPM) and MySQL support (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP).

This tutorial describes how you can set up a single dedicated server as a virtual multiserver environment using OpenVZ with dedicated Web & MySQL, Email and DNS servers on Debian Squeeze. Also, you will learn how to maintain all these servers. As an addition, you will learn how to install some very useful packages on all of them, how to protect them and how to monitor them. At the end you will have a fully functional virtual multiserver environment, ready for shared hosting.

This tutorial shows how you can set up an Ubuntu Studio 12.04 desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge. Please note that Ubuntu Studio 12.04 uses Xfce as the default desktop environment.

This document describes how to add WiKID two-factor authentication to Apache 2.2.22 using mod_auth_radius on Ubuntu 12.04. It is also recommended that you consider using mutual https authentication for web applications that are worthy of two-factor authentication. Strong mutual authentication means that the targeted website is authenticated to the user in some cryptographically secure manner, thwarting most man-in-the-middle attacks. The use of cryptography is key. While some sites use an image in an attempt to validate a server, it should be noted that any man-in-the-middle could simply replay such an image.

Backups are usually made in one of two ways - either file-based which means that single files are backed up, often via synchronization and on an external disk, or image-based which means that a whole partition is stuffed into an image file that can be restored on the partition, containing everything there was on it. This tutorial covers image-based backups using Partimage from a live desktop environment.

This tutorial shows how you can install and run OXID eShop Community Edition (version 4.5.9) on a Debian Squeeze or Ubuntu 11.10 system that has nginx installed instead of Apache (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP). OXID eShop is a feature-rich ecommerce platform; I will use the Community Edition here which is licensed under an open source certified license (GPL v3.0). nginx is a HTTP server that uses much less resources than Apache and delivers pages a lot of faster, especially static files.

(R)?ex is a server orchestration and configuration management tool. With (R)?ex you can manage all your boxes from a central point through the complete process of configuration management and software deployment. In this guide I will show you with the help of a project how to use (R)?ex to configure your servers and how to deploy software.

This tutorial shows how to set up a standalone storage server on Debian Squeeze. Instead of NFS, I will use GlusterFS here. The client system 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.

This tutorial shows how you can set up a Xubuntu 12.04 desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge.

LAMP is short for Linux, Apache, MySQL, PHP. This tutorial shows how you can install an Apache2 webserver on an Ubuntu 12.04 LTS server with PHP5 support (mod_php) and MySQL support.

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 a Debian Squeeze server.

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, so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV. I will also show how to install SquirrelMail as a webmail interface.

EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. It is a pass-through filesystem, not an encrypted block device, which means it is created on top of an existing filesystem. This tutorial shows how you can use EncFS on Debian Squeeze/Ubuntu 11.10 to encrypt your data.

This tutorial shows how to prepare an Ubuntu 12.04 LTS (Precise Pangolin) server (with nginx, BIND, Dovecot) for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache or nginx web server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This setup covers nginx (instead of Apache), BIND (instead of MyDNS), and Dovecot (instead of Courier).
