How To Set Up WebDAV With MySQL Authentication On Apache2 (Debian Lenny)

This guide explains how to set up WebDAV with MySQL authentication (using mod_auth_mysql) on Apache2 on a Debian Lenny 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.

How To Set Up MySQL Database Replication On Fedora 10

This tutorial describes how to set up database replication in MySQL. 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. I will use Fedora 10 for the master and slave in this tutorial.

How To Add Two-Factor Authentication To phpBB

This document describes how to add WiKID two-factor authentication to phpBB through Apache using mod_auth_xradius. Given the recent attack against phpBB and the exposure of it's users' passwords, we thought two-factor authentication might be timely.

IP Address Geolocation From MySQL

In this short tutorial I will use a local MySQL database to do IP addresses geolocation.

Quick DB Setups With MySQL Sandbox

There are various reasons to set up quick "sandbox" instances of MySQL. You can use them to test different types of replication (such as master-master or various slave topologies), to test your code against different versions of MySQL, or to setup instances of MySQL on a per developer basis where each person has their own database running on a different port so they can breakdown/setup the DB easily or make schema changes without affecting other team members. A perfect tool to do all of these things easily is MySQL Sandbox.

Setting, Changing And Resetting MySQL Root Passwords

This tutorial explains how you can set, change and reset (if you've forgotten the password) MySQL root passwords. Time and again I see problems like mysqladmin:  connect to server at 'localhost' failed error: 'Access denied for user 'root'@'localhost' (using password: YES)'. So I thought it's time to remind you how to solve MySQL related password problems. If you are just looking for a quick fix how to reset a MySQL root password you can find that at the bottom of this tutorial.

Adding An ODBC Driver For MySQL On Ubuntu

Sometimes you may find the need to develop cross platform applications which make use of a database. ODBC can be a solution to your portability needs, but unfortunately it is not as easy to set up an ODBC connection on Linux as it is on Windows. This tutorial attempts to shed some light on this process by guiding you towards adding an ODBC driver on Ubuntu. The process described below has been tested on Ubuntu 8.04 and Ubuntu 8.10.

How To Back Up MySQL Databases With mylvmbackup On Ubuntu 8.10

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 8.10 server.

ZRM 2.1: Backing Up MySQL Partitioned Tables

MySQL 5.1 is generally available for production use. One of the key features of MySQL 5.1 is partitioning. This how to shows how to install and configure Zmanda Recovery Manager for MySQL (ZRM) 2.1 to perform backup and recovery of MySQL partitioned tables.

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

This tutorial explains how you can set up MySQL master-master replication on four MySQL nodes (running on Debian Etch). The difference to a two node master-master replication is that if you have more than two nodes, the replication goes in a circle, i.e., with four nodes, the replication goes from node1 to node2, from node2 to node3, from node3 to node4, and from node4 to node1.
