Unix+clones How To Set Up Database Replication In MySQL
Post date: December 14, 2005, 14:12 Category: Software Views: 81
Tutorial quote: 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.

In this tutorial I will show how to replicate the database exampledb from the master with the IP address 192.168.0.100 to a slave. Both systems (master and slave) are running Debian Sarge; however, the configuration should apply to almost all distributions with little or no modification.
Linux The PartImage Handbook
Post date: May 21, 2005, 11:05 Category: Software Views: 43
Tutorial quote: - Partition Image is a Linux/UNIX partition imaging utility: it saves partitions formatted using the Ext2FS (the linux standard), ReiserFS (a new journaled and powerful file system), JFS IBM journaled file systems from AIX, NTFS (Windows NT File System), FAT16/32 (DOS & Windows file systems), or HPFS (OS/2 file system) file system formats to an image file. Only used blocks are copied. The image file can be compressed in the GZIP/BZIP2 formats to save disk space, and split into multiple files to be copied on removable media (ZIP for example), or burned on a CD-R ...

- This allows the user to save a full Linux/Windows system, with a single operation. When problems occur (viruses, crash, error, ...), you just have to restore, and after several minutes, all your system is restored (boot, files, ...), and fully working.

- This is very useful when installing the same software on many machines: just install one of them, create an image, and then restore the image on all other machines. After the first one, each subsequent installation can be made automaticaly, and only requires a few minutes.
Debian Building A Virtual Server (VPS) With Debian 3.1 (Sarge) And OpenVZ
Post date: March 20, 2006, 15:03 Category: System Views: 36
Tutorial quote: In this HowTo I will describe the steps to be taken to prepare a server for OpenVZ virtual machines on Debian 3.1 (Sarge) 32Bit Linux. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernal patch is licensed under the GPL license, and the user-level tools are under the QPL license.
Gentoo Bandwidth limiting howto
Post date: June 12, 2005, 22:06 Category: Network Views: 120
Tutorial quote: Linux has a very powerful mechanism for controlling network bandwidth usage. As being powerful inevitably implies being complex, this feature is documented in lengthy and exhaustive documents in great details. These documents however can prove to be excessive in their length and language to users who are looking for simple solutions for simple questions. This guide aims to give a short and practical introduction on how to solve some common issues that users tend to experience on an everyday basis.

Linux Performance Tools for Optimizing Linux: Process-Specific CPU
Post date: June 1, 2005, 03:06 Category: Optimizing Views: 140
Tutorial quote: The tools to analyze the performance of applications are varied and have existed in one form or another since the early days of UNIX. It is critical to understand how an application is interacting with the operating system, CPU, and memory system to understand its performance. This chapter will help you understand where the bottleneck in your system is occuring, and how to fix it.

I went through that myself, and I decided to write a howto to ease your pain ;)
Linux The Linux /proc Filesystem as a Programmers' Tool
Post date: June 22, 2005, 05:06 Category: Programming Views: 137
Tutorial quote: My entry into systems programming was guided by my desire to understand further the operating systems I was working with daily as a contract UNIX and, later, Linux system administrator. The result of this was ifchk, a packet sniffer detector I wrote in C and released in June of 2003. ifchk initially was written under IRIX and then ported to Linux, mostly under the 2.4 kernel. The current ifchk revision, beta 4, recently was released and beta 5 is on the way.

My work on ifchk has allowed me to examine programmatically several areas of operating system functionality. Examples include the Linux netlink(7) and rtnetlink(7) facilities, device control--that is, network interfaces--via ioctl(2), signals and proc, the process filesystem. Proc and its ability to display a wide array of data concerning the runtime state of a system are the focus of our discussion here.
Linux Mastering the Enterprise Volume Management System
Post date: April 13, 2005, 15:04 Category: System Views: 62
Tutorial quote: The Enterprise Volume Management System, or EVMS, is a disk, partition, and file system manager for Linux that claims to be a comprehensive tool for all disk management tasks. I ran across EVMS and found the idea appealing, so I decided to try it out. I've been working with it for a couple of weeks now, and this article describes what I found.
