Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Ubuntu 12.10
This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database. This tutorial is based on Ubuntu 12.10.
Running concrete5 On Nginx (LEMP) On Debian Squeeze/Ubuntu 12.10
This tutorial shows how you can install and run a concrete5 web site on a Debian Squeeze or Ubuntu 12.10 system that has nginx installed instead of Apache (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP). nginx is a HTTP server that uses much less resources than Apache and delivers pages a lot of faster, especially static files. concrete5 is a free and open-source content management system (CMS).
Encrypt Your Data With EncFS (Ubuntu 12.10)
EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. It is a pass-through filesystem, not an encrypted block device, which means it is created on top of an existing filesystem. This tutorial shows how you can use EncFS on Ubuntu 12.10 to encrypt your data.
The Perfect Desktop - Linux Mint 14 (Nadia)
This tutorial shows how you can set up a Linux Mint 14 (Nadia) 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.
How To Upgrade From Linux Mint 13 (Maya) To 14 (Nadia) With apt
This tutorial shows how you can upgrade from Linux Mint 13 (Maya) to Linux Mint 14 (Nadia) with apt. Please note that this is not the recommended way, and it might break your system, however, for me it worked fine.
A Beginner's Guide To btrfs
This guide shows how to work with the btrfs file system on Linux. It covers creating and mounting btrfs file systems, resizing btrfs file systems online, adding and removing devices, changing RAID levels, creating subvolumes and snapshots, using compression and other things. btrfs is still marked as experimental, but all those features make it a very interesting and flexible file system that should be taken into consideration when you look for the right file system.
Creating Simple Virtual Hosts With mod_mysql_vhost On Lighttpd (Ubuntu 12.10)
This guide explains how you can use mod_mysql_vhost to create simple virtual hosts on a lighttpd web server on Ubuntu 12.10. With mod_mysql_vhost, lighttpd can read the vhost configuration from a MySQL database. Currently, you can store the domain and the document root in the MySQL database which results in very simple virtual hosts. If you need more directives for your vhosts, you'd have to configure them in the global section of lighttpd.conf, which means they'd be valid for all vhosts. Therefore, mod_mysql_vhost is ideal if your vhosts differ only in the domain and document root.
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.
Virtual Hosting With vsftpd And MySQL On Ubuntu 12.10
Vsftpd is one of the most secure and fastest FTP servers for Linux. Usually vsftpd is configured to work with system users. This document describes how to install a vsftpd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine.
Rollback To A Working State With btrfs + apt-btrfs-snapshot On Ubuntu 12.10
This tutorial explains how you can revert failed apt operations (like apt-get upgrade) and roll back to the previous system state with apt-btrfs-snapshot on an Ubuntu 12.10 system that uses the btrfs file system. apt-btrfs-snapshot creates a snapshot of the system before the apt operation. Being able to easily restore the previous system state after a failed apt operation takes away much of the pain system administrators have to deal with normally and is one of the greatest features of the btrfs file system.
