How to configure a low-cost load-balanced LAMP cluster

Post date: April 25, 2006, 11:04 Category: Network Views: 6008 Comments
Tutorial quote: The ubiquitous Linux, Apache, MySQL, and PHP/Perl/Python (LAMP) combination powers many interactive Web sites and projects. It's not at all unusual for demand to exceed the capacity of a single LAMP-powered server over time. You can take load off by moving your database to a second server, but when demand exceeds a two-server solution, it's time to think cluster.

Virtual Users And Domains With Postfix, Courier And MySQL (Debian Etch)

Post date: June 5, 2007, 23:06 Category: Installing Views: 2902 Comments
Tutorial quote: 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 will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses.

Setting Up Master-Master Replication With MySQL 5 On Debian Etch

Post date: October 25, 2007, 11:10 Category: Miscellaneous Views: 3168 Comments
Tutorial quote: Since version 5, MySQL comes with built-in support for master-master replication, solving the problem that can happen with self-generated keys. In former MySQL versions, the problem with master-master replication was that conflicts arose immediately if node A and node B both inserted an auto-incrementing key on the same table. The advantages of master-master replication over the traditional master-slave replication are that you do not have to modify your applications to make write accesses only to the master, and that it is easier to provide high-availability because if the master fails, you still have the other master.

Automatically Scan Uploaded Files For Viruses With php-clamavlib

Post date: January 14, 2007, 21:01 Category: Security Views: 4274 Comments
Tutorial quote: This guide describes how you can automatically scan files uploaded by users through a web form on your server using PHP and ClamAV. That way you can make sure that your upload form will not be abused to distribute malware. To glue PHP and ClamAV, we install the package php5-clamavlib/php4-clamavlib which is rather undocumented at this time. That package is available for Debian Etch and Sid and also for Ubuntu Dapper Drake and Edgy Eft.

How To Set Up suPHP With PHP4 And PHP5

Post date: June 17, 2006, 06:06 Category: Security Views: 3818 Comments
Tutorial quote: This tutorial shows how to install and use suPHP with PHP4 and PHP5. suPHP is a tool for executing PHP scripts with the permissions of their owners instead of the Apache user. With the help of suPHP you can also have PHP4 and PHP5 installed at the same time which I will describe at the end of this article.

Automated distributed backups for laptops

Post date: February 14, 2006, 21:02 Category: Network Views: 2584 Comments
Tutorial quote: This document will describe the setup I made for automating the backup tasks for all laptops here in the house. My servers use the same backup server and infrastructure, but right now they don't have the checks and scripts because they are online 24/7 and my backup server is triggering the backup process. This is however not true at all for the laptops.

Laptops can be at different places, powered down, suspended, put to sleep etc. So I needed a different approach for them.

OpenVZ On Debian Etch For Webservers

Post date: December 26, 2006, 21:12 Category: System Views: 3290 Comments
Tutorial quote: Virtualization is a good practice for servers, since it makes things more secure, scalable, replacable, and replicable, all this at the cost of little added complexity. This guide was written during an install of a Supermicro machine with two dual-core opterons (64-bit), two identical disks (for RAID) and a load of memory. Why OpenVZ and not XEN or the recent KVM kernel module? Well, XEN is not very stable for 64-bit architectures (yet), and it comes with quite a bit of overhead (every VM runs its own kernel) due to its complexity. KVM is very simple but restricts you to run a kernel as one process, so the VM cannot benefit from multi core systems.

Creating Encrypted FTP Backups With duplicity And ftplicity On Debian Etch

Post date: December 18, 2007, 12:12 Category: Miscellaneous Views: 3338 Comments
Tutorial quote: When you rent a dedicated server nowadays, almost all providers give you FTP backup space for your server on one of the provider's backup systems. This tutorial shows how you can use duplicity and ftplicity to create encrypted (so that nobody with access to the backup server can read sensitive data in your backups) backups on the provider's remote backup server over FTP. ftplicity is a duplicity wrapper script (provided by the German computer magazine c't) that allows us to use duplicity without interaction (i.e., you do not have to type in any passwords).

How To Create A Debian Wheezy (Testing) OpenVZ Template

Post date: September 15, 2011, 08:09 Category: Miscellaneous Views: 4358 Comments
Tutorial quote: This tutorial explains how to create an OpenVZ template for Debian Wheezy (Debian Testing) that you can use to create virtual Debian Wheezy machines under OpenVZ. I searched for a Debian Wheezy OpenVZ template, but couldn't find one, that's why I decided to create it myself. This guide can also be used for creating Debian Lenny templates and templates for recent Ubuntu versions.
