How To Set Up A Load-Balanced MySQL Cluster

Post date: March 31, 2006, 19:03 Category: Software Views: 4335 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.

Installing Ubuntu Or Fedora From A Windows Or Linux System With UNetbootin

Post date: October 7, 2007, 09:10 Category: Installing Views: 4500 Comments
Tutorial quote: UNetbootin is a tool that allows you to install various Linux distributions (Ubuntu, Fedora, Mandriva, OpenSuSE, Debian, ArchLinux) from a Windows or a Linux desktop over the internet (i.e., you do not need to burn the Ubuntu, Fedora, ... CDs). Unlike the Ubuntu installation with Wubi, real partitions are created during the installation. In the end, you have a dual-boot system (Linux/Windows or Linux/Linux).

Connecting to a Wireless LAN with Linux, Part 1

Post date: April 13, 2005, 19:04 Category: Hardware Views: 4197 Comments
Tutorial quote: Wireless hardware for Linux is a moving target. The wireless network adapter that worked fine with Linux yesterday may be released with an unsupported radio chipset today, and with no indication of the change. So buyer beware--always confirm the chipset before you buy. The good news is a lot of wireless adapters have native Linux support, and for those that don't, the NdisWrapper utility lets you use the Windows drivers on your Linux box.

Installing IRIX 6.5 Across a Network

Post date: May 21, 2005, 10:05 Category: Installing Views: 6796 Comments
Tutorial quote: Installing across a network may be desirable for a number of reasons, usually speed, convenience (disks/CDROM attached to remote system) or necessity. I've done network installs on O2s, Octanes and Indys; in each case, a remote disk file system contained local copies of all the relevant 6.5 media.

Nginx HTTP Server + PHP5 (With fast-cgi And xcache) On Ubuntu Feisty Fawn

Post date: October 10, 2007, 10:10 Category: Installing Views: 4851 Comments
Tutorial quote: Nginx HTTP Server + PHP5 (With fast-cgi And xcache) On Ubuntu Feisty Fawn

This HowTo describes the implementation of Nginx with php5 support (through FastCGI). The fast-cgi process will be initiated via spawn-fcgi. Nginx is a great replacement of Apache with very low memory footprint and contrary to Lighttpd, does not suffer from memory leak over time. You can then use all the memory left to unleash the power of mysql for instance by increasing the default query cache.

Ripping cds using FLAC

Post date: June 22, 2005, 13:06 Category: Multimedia Views: 39291 Comments
Tutorial quote: I'm a fan of sound quality, and since I have some disc space free, I decided to rip some CDs to the free lossless audio codec (FLAC) instead of ogg vorbis which I was using before. The compression rate is for now about 50%, depending on the content of the audio file. Also I found that FLAC encodes VERY fast (~60-140x on my Athlon XP 2400+).
