It uses LVM's snapshot feature to do so. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. This article shows how to use it on an Ubuntu 12.10 server. falko Tue, 15 Jan 2013 11:19:30 GMT http://www.howtoforge.com/how-to-convert-an-ext3-ext4-root-file-system-to-btrfs-on-ubuntu-12.10 ext3 and ext4 file systems can be converted to btrfs. For non-root file systems, this can be done online (i.e., without reboot), while for root file systems we need to boot into some kind of rescue system or Live CD. This guide explains how to convert an ext3 or ext4 root file system into btrfs on Ubuntu 12.10 and how to roll back to ext3/ext4 again if desired. falko Tue, 27 Nov 2012 09:53:50 GMT http://www.howtoforge.com/how-to-upgrade-ubuntu-12.04-lts-precise-pangolin-to-12.10-quantal-quetzal-desktop-and-server The new Ubuntu 12.10 (Quantal Quetzal) has just been released. This guide shows how you can upgrade your Ubuntu 12.04 LTS desktop and server installations to Ubuntu 12.10. falko Fri, 19 Oct 2012 09:44:52 GMT http://www.howtoforge.com/the-perfect-desktop-ubuntu-12.10-quantal-quetzal This tutorial shows how you can set up an Ubuntu 12.10 desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge. falko Thu, 22 Nov 2012 09:32:18 GMT http://www.howtoforge.com/the-perfect-desktop-xubuntu-12.10-quantal-quetzal This tutorial shows how you can set up a Xubuntu 12.10 desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge. Xubuntu uses the lightweight XFCE desktop environment. falko Sun, 28 Oct 2012 10:37:06 GMT http://www.howtoforge.com/perfect-server-ubuntu-12.10-apache2-bind-dovecot-ispconfig-3 This tutorial shows how to prepare an Ubuntu 12.10 (Quantal Quetzal) server (with Apache2, BIND, Dovecot) for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache or nginx web server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This setup covers Apache (instead of nginx), BIND (instead of MyDNS), and Dovecot (instead of Courier). falko Tue, 23 Oct 2012 09:38:24 GMT http://www.howtoforge.com/vboxheadless-running-virtual-machines-with-virtualbox-4.2-on-a-headless-ubuntu-12.10-server This guide explains how you can run virtual machines with VirtualBox 4.2 on a headless Ubuntu 12.10 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI. falko Tue, 18 Dec 2012 14:17:35 GMT http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-mysql-and-squirrelmail-ubuntu-12.10 This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier, so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords. falko Tue, 06 Nov 2012 10:35:52 GMT http://www.howtoforge.com/virtualization-with-kvm-on-ubuntu-12.10 This guide explains how you can install and use KVM for creating and running virtual machines on an Ubuntu 12.10 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V. falko Tue, 13 Nov 2012 13:11:23 GMT
