Install Multiple Linux Distributions Via PXE (The Easy Way)

The following script will set up a PXE config on your server, making it possible to install major Linux distributions via netboot.

Installing PHP 5.3, Nginx And PHP-fpm On Ubuntu/Debian

Since Apache is most of the time a memory hungy process, people started to look for different ways to host their website. Apache is clearly not the only webserver available. A few good examples are lighttpd and nginx. In this tutorial I will show you how to install it on your Ubuntu server. This tutorial also applies to Debian, though. There is only a very small difference.

How To Set Up MySQL Database Replication With SSL Encryption On Ubuntu 9.10

This tutorial describes how to set up database replication in MySQL using an SSL connection for encryption (to make it impossible for hackers to sniff out passwords and data transferred between the master and slave). MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. This is not a backup policy because an accidentally issued DELETE command will also be carried out on the slave; but replication can help protect against hardware failures though.

Setting Up A PXE Install Server On Ubuntu 9.10

This tutorial shows how to set up a PXE (short for preboot execution environment) install server with Ubuntu 9.10 (Karmic Koala). A PXE install server allows your client computers to boot and install a Linux distribution over the network, without the need of burning Linux iso images onto a CD/DVD, boot floppy images, etc. This is handy if your client computers don't have CD or floppy drives, or if you want to set up multiple computers at the same time (e.g. in a large enterprise), or simply because you want to save the money for the CDs/DVDs.

VBoxHeadless - Running Virtual Machines With VirtualBox 3.1 On A Headless Ubuntu 9.10 Server

This guide explains how you can run virtual machines with Sun VirtualBox 3.1 on a headless Ubuntu 9.10 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.

Installing mod_geoip for Apache2 On Ubuntu 9.10

This guide explains how to set up mod_geoip with Apache2 on an Ubuntu 9.10 system. mod_geoip looks up the IP address of the client end user. This allows you to redirect or block users based on their country. You can also use this technology for your OpenX (formerly known as OpenAds or phpAdsNew) ad server to allow geo targeting.

Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Ubuntu 9.10 (Karmic Koala)

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.

Striping Across Four Storage Nodes With GlusterFS On Ubuntu 9.10

This tutorial shows how to do data striping (segmentation of logically sequential data, such as a single file, so that segments can be assigned to multiple physical devices in a round-robin fashion and thus written concurrently) across four single storage servers (running Ubuntu 9.10) with GlusterFS. The client system (Ubuntu 9.10 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.

How To Set Up A Terminal Server In Linux Using Ubuntu 9.10 And FreeNX

FreeNX is an open source implementation of NoMachine's NX Server. It is a bit more akin to Microsoft's RDP protocol that the usual VNC, so while keeping bandwidth to a minimum, it maintains good visual quality and responsiveness.

How To Set Up An SSL Vhost Under Apache2 On Ubuntu 9.10/Debian Lenny

This article explains how you can set up an SSL vhost under Apache2 on Ubuntu 9.10 and Debian Lenny so that you can access the vhost over HTTPS (port 443). SSL is short for Secure Sockets Layer and is a cryptographic protocol that provides security for communications over networks by encrypting segments of network connections at the transport layer end-to-end. We use the mod_ssl Apache module here to provide strong cryptography for Apache2 via SSL by the help of the Open Source SSL toolkit OpenSSL.
