Setting Up A PXE Install Server For Multiple Linux Distributions On Debian Lenny

Post date: May 26, 2009, 10:05 Category: Miscellaneous Views: 7200 Comments
Tutorial quote: This tutorial shows how to set up a PXE (short for preboot execution environment) install server on Debian Lenny. A PXE install server allows your client computers to boot and install a Linux distribution over the network, without the need of burning Linux iso images onto a CD/DVD, boot floppy images, etc. This is handy if your client computers don't have CD or floppy drives, or if you want to set up multiple computers at the same time (e.g. in a large enterprise), or simply because you want to save the money for the CDs/DVDs. In this article I show how to configure a PXE server that allows you to boot multiple distributions (i386 and x86_64): Debian Lenny, Ubuntu 9.04, Fedora 10, CentOS 5.3, OpenSuSE 11.1, and Mandriva 2009.1.

Monitoring and Managing Linux Software RAID

Post date: April 15, 2005, 23:04 Category: System Views: 2773 Comments
Tutorial quote: Systems administrators managing a data center face numerous challenges to achieve required availability and uptime. Two of the main challenges are shrinking budgets (for hardware, software, and staffing) and short deadlines in which to deliver solutions. The Linux community has developed kernel support for software RAID (Redundant Array of Inexpensive Disks) to help meet those challenges. Software RAID, properly implemented, can eliminate system downtime caused by disk drive errors. The source code to the Linux kernel, the RAID modules, and the raidtools package are available at minimal cost under the GNU Public License. The interface is well documented and comprehensible to a moderately experienced Linux systems administrator.

In this article, I'll provide an overview of the software RAID implementation in the Linux 2.4.X kernel. I will describe the creation and activation of software RAID devices as well as the management of active RAID devices. Finally, I will discuss some procedures for recovering from a failed disk unit.

Tutorial quote: This tutorial shows how to set up a PXE (short for preboot execution environment) install server with Ubuntu 6.10 (Edgy Eft). A PXE install server allows your client computers to boot and install a Linux distribution over the network, without the need of burning Linux iso images onto a CD/DVD, boot floppy images, etc. This is handy if your client computers don't have CD or floppy drives, or if you want to set up multiple computers at the same time (e.g. in a large enterprise), or simply because you want to save the money for the CDs/DVDs. In this article I show how to configure a PXE server that allows you to boot multiple distributions: Ubuntu Edgy/Dapper, Debian Etch/Sarge, Fedora Core 6, CentOS 4.4, OpenSuSE 10.2, and Mandriva 2007.

Setting up yum on SUSE LINUX 10.0

Post date: October 16, 2005, 16:10 Category: System Views: 5453 Comments
Tutorial quote: Why should I use yum and not yast? Well, yast is nice, but has some disadvantages: It can#t check for gpg keys, you have to trust the mirrors you add. And, speaking about mirrors, yast has no real mirror management for one source. Especially in these times the most and best known SUSE mirrors are very slow or just closed down, so you have to add other sources in yast. But yast needs your clicks when a mirror is not reachable, and if you enter several sources just as mirrors, it checks every single source - that takes quite a long time!
A last reason (which is not important know because SUSE LINUX has a ugly workaround) is that yast is not able to handle packages for different architectures - it can only install packages for one architecture.

How To Set Up A Load-Balanced MySQL Cluster

Post date: March 31, 2006, 19:03 Category: Software Views: 3839 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.
