User-Mode Linux

Post date: December 8, 2005, 13:12 Category: Software Views: 4597 Comments
Tutorial quote: One of the largest efforts involved with software engineering is testing the software to make sure that it works as designed. Testing can require several different types of system configurations and could require multiple instances of Linux. One way to create this type of environment is to use a virtual machine.

User-Mode Linux (UML) is a fully functional Linux kernel. It runs its own scheduler and virtual memory (VM) system, relying on the host kernel for hardware support. It includes virtual block, network, and serial devices to provide an environment that is almost as full-featured as a hardware-based machine. UML cannot destroy the host machine. Furthermore, the UML block devices, also called disks, can be files on the native Linux file system, so you cannot affect the native block devices. This is very useful when you're testing and debugging block operations.

Using a jail as a virtual machine

Post date: April 12, 2005, 18:04 Category: System Views: 4468 Comments
Tutorial quote: This article shows you how I created a jail for the OSW website. It runs in a jail on the same system as this website. I originally did this install back in November 2003 and the notes from that session form the basis of this article. I have need to recreate the jail now as we recently had an HDD failure.

A jail is useful for many purposes. In my case, I wanted to give the OSW project a place to run their websites, mailing lists, etc, but at the same time keep them isolated from the rest of the machine. In short, it gives them a virtual machine, and it gives me peace of mind knowing that I have less to worry about with respect to the rest of the machine.

Setting Up Master-Master Replication With MySQL 5 On Debian Etch

Post date: October 25, 2007, 11:10 Category: Miscellaneous Views: 3840 Comments
Tutorial quote: Since version 5, MySQL comes with built-in support for master-master replication, solving the problem that can happen with self-generated keys. In former MySQL versions, the problem with master-master replication was that conflicts arose immediately if node A and node B both inserted an auto-incrementing key on the same table. The advantages of master-master replication over the traditional master-slave replication are that you do not have to modify your applications to make write accesses only to the master, and that it is easier to provide high-availability because if the master fails, you still have the other master.

How To Set Up Database Replication In MySQL On Ubuntu 9.10

Post date: January 12, 2010, 12:01 Category: Miscellaneous Views: 3653 Comments
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.
