How to set up a home DNS server

Post date: December 17, 2006, 17:12 Category: Network Views: 10164 Comments
Tutorial quote: In the first part of this series on the Domain Name System (DNS), we set up a caching nameserver that allowed our clients to take advantage of faster network operations by caching frequently requested DNS queries. In this article, we will extend our caching nameserver to a master nameserver that is responsible for managing the authoritative information for our internal client hostnames.

Tutorial quote: djbdns is a very secure suite of DNS tools that consists out of multiple parts: dnscache, a DNS cache that can be used in /etc/resolv.conf instead of your ISP's name servers and that tries to sort out wrong (malicious) DNS answers; axfrdns, a service that runs on the master DNS server and to which the slaves connect for zone transfers; and tinydns, the actual DNS server, a very secure replacement for BIND.

How To Back Up MySQL Databases Without Interrupting MySQL

Post date: May 12, 2007, 23:05 Category: System Views: 3632 Comments
Tutorial quote: This article describes how you can back up MySQL databases without interrupting the MySQL service. Normally, when you want to create a MySQL backup, you either have to stop MySQL or issue a read lock on your MySQL tables in order to get a correct backup; if you do not do it this way, you can end up with an inconsistent backup. To get consistent backups without interrupting MySQL, I use a little trick: I replicate my MySQL database to a second MySQL server, and on the second MySQL server I use a cron job that creates regular backups of the replicated database.

Tunneling MySQL connections through SSH

Post date: January 2, 2007, 20:01 Category: Security Views: 3482 Comments
Tutorial quote: This is a description of how to set up a secure tunnel between your MySQL Server and a locally running MySQL Administrator using Putty. By creating a secure tunnel to your MySQL server using Putty, you can grant localhost access to powerful applications like MySQL Administrator while at the same time, make your server appear as if it isn't even there. In effect, make your MySQL server disappear from the outside world.

How To Set Up A Load-Balanced MySQL Cluster

Post date: March 31, 2006, 19:03 Category: Software Views: 3847 Comments
Tutorial quote: This tutorial shows how to configure a MySQL 5 cluster with three nodes: two storage nodes and one management node. This cluster is load-balanced by a high-availability load balancer that in fact has two nodes that use the Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster).

In this document I use Debian Sarge for all nodes. Therefore the setup might differ a bit for other distributions. The MySQL version I use in this setup is 5.0.19. If you do not want to use MySQL 5, you can use MySQL 4.1 as well, although I haven't tested it.

This howto is meant as a practical guide; it does not cover the theoretical backgrounds. They are treated in a lot of other documents in the web.
