Storing Files/Directories In Memory With tmpfs

Post date: December 9, 2008, 12:12 Category: Miscellaneous Views: 2956 Comments
Tutorial quote: You probably know that reading from RAM is a lot of faster than reading files from the hard drive, and reduces your disk I/O. This article shows how you can store files and directories in memory instead of on the hard drive with the help of tmpfs (a file system for creating memory devices). This is ideal for file caches and other temporary data (such as PHP's session files if you are using session.save_handler = files) because the data is lost when you power down or reboot the system.

It makes it very easy to create and manage OpenVZ VMs even for people with little technical knowledge.

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

Post date: November 20, 2008, 12:11 Category: Miscellaneous Views: 2932 Comments
Tutorial quote: This tutorial explains how you can set up MySQL master-master replication on four MySQL nodes (running on Debian Etch). The difference to a two node master-master replication is that if you have more than two nodes, the replication goes in a circle, i.e., with four nodes, the replication goes from node1 to node2, from node2 to node3, from node3 to node4, and from node4 to node1.

How To Back Up An Ubuntu 8.10 System With SystemImager

Post date: November 13, 2008, 12:11 Category: Miscellaneous Views: 3293 Comments
Tutorial quote: SystemImager lets you create images of your Linux installations. To do so, you need an image server (should have enough disk space to store your images) and a so-called golden client (i.e., the system of which you want to make an image). This means that you have to install some software on your image server and on your golden client in order to run SystemImager. This tutorial shows how to install a SystemImager server and a SystemImager client, both using Ubuntu 8.10, and how to create/update/restore/delete images.

Using IPv6 On Debian Etch

Post date: November 6, 2008, 11:11 Category: Miscellaneous Views: 2782 Comments
Tutorial quote: This document describes how you can configure a Debian Etch system for IPv6 so that a) it can connect to other IPv6 hosts and b) other IPv6 hosts can connect to it. IPv6 should become more important in the future as recent estimates assume that there will be no more IPv4 addresses left by 2010 or 2011. Therefore it's time time to learn IPv6.
