Load-balancing devices are becoming more common to support high-traffic Web sites that can’t process all requests on a single server.

Rather than move to more powerful hardware, it makes sense to create clusters, or farms, of servers. In fact, with new functionality that can send traffic to a given server or farm based on the URL, it’s possible to have a single Web site that is spread across several different clusters of servers.

Speed up your hard drive
Many Linux distributions are installed in such a way that the 32-bit input/output (I/O) and DMA capabilities of today’s UltraATA/66 hard drives are not fully exploited.

The Dynamic Host Configuration Protocol (DHCP) allows you to specify network parameters on a server and have client computers query the server for their information such as IP, netmask, gateway, DNS, etc. In addition to not having to statically assign network information to numerous clients, you also do not need to specify the IP of the DHCP server as this discovery is done via broadcast packets; the caveat to this is that you must have one DHCP server per broadcast domain. In case it’s not blatantly obvious, the power of DHCP is that if anything changes on your network such as the IP of a DNS server, you only need to edit one configuration file even if you have hundreds of clients.

Note: I have not only the Microsoft MN-730 Wireless G Card on an Athlon Desktop machine, but I also have the matching MN-700 “Base Station”/router.

Note 2: Microsoft networking cards use the broadcom chipset. So THEY WILL work in linux and work very well with strong signal.

One of the most confusing issues for Windows defector is that of file permissions. Home-user Windows systems have no concept of file ownership, which depending on your situation, can be a good or bad thing. You need to keep in mind that Linux is at heart a Unix system, and Unix is built to support multiple users. Even on a home computer permissions are a useful feature which allow you to block sensitive files from being edited, or even read by non-authorized people.

This tutorial is written in two ways. One way is for the compiled MySQL and one for the installed MySQL by RPM [tested only in Fedora]. It’s not big deal, but I hope it is accessible also to newbies because the directory’s change in both examples.

Cron comes from the word chronos, the Greek word for time. Cron is a utility that can help with automating certain tasks in Linux. For example if you would like to create backups of certain files or directories each night while you are sleeping, you can use Cron to automate this.

How to Use the Cron and Crontab commands
The ‘Cron’ Command

The cron command starts a process that executes commands at specified dates and times. Regularly scheduled commands can be specified according to instructions found in the crontab files in the directory /var/spool/cron/crontabs. Users can submit their own crontab files via the crontab command.

Notes
You MUST have a third server as a managment node but this can be shut down after the cluster starts. Also note that I do not recommend shutting down the managment server (see the extra notes at the bottom of this document for more information). You can not run a mysql cluster with just two servers.

First, you need a sane build environment. In the open source world, that means GNU tools. Make sure you have the following tools installed. If not, get them from your nearest RPM repository, or from the GNU site.

autoconf
automake
binutils
gcc (I used version 2.95.3)
glib
gzip
libtool
make
wget
zlib
Install all of the packages listed above.
