Striping Across Four Storage Nodes With GlusterFS 3.2.x On CentOS 6.3

This tutorial shows how to do data striping (segmentation of logically sequential data, such as a single file, so that segments can be assigned to multiple physical devices in a round-robin fashion and thus written concurrently) across four single storage servers (running CentOS 6.3) with GlusterFS. The client system (CentOS 6.3 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Debian Wheezy Local Git Server With Git Lite Workflow

This howto describes a shared local git [1] server setup for a small team. This is a repository layout that is familiar to anyone used to working with a traditional version control system. One of the tutorial objectives is to show detailed steps to prepare the server and publish the code on a public service like Github, Gitorius et. al. A second objective is to introduce the Git Lite Workflow in team development. This serves as an introduction to gits powerful branch and merge features. Your personal favorite workflow may be different compared to this model.

Distributed Storage Across Four Storage Nodes With GlusterFS 3.2.x On CentOS 6.3

This tutorial shows how to combine four single storage servers (running CentOS 6.3) to one large storage server (distributed storage) with GlusterFS. The client system (CentOS 6.3 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Installing Debian Wheezy (testing) With debootstrap From A Grml Live Linux

This tutorial explains how to install Debian Wheezy (testing) with the help of debootstrap from a Grml Live Linux system (like it is used as a rescue system at Webtropia). This should work - with minor changes - for other Debian and Ubuntu versions as well. By following this guide, it is possible to configure the system to your needs (OS version, partitioning, RAID, LVM, etc.) instead of depending on the few pre-configured images that your server provider offers.

How To Automatically Add A Disclaimer To Outgoing Emails With alterMIME (Postfix On Debian Squeeze)

This tutorial shows how to install and use alterMIME. alterMIME is a tool that can automatically add a disclaimer to emails. In this article I will explain how to install it as a Postfix filter on Debian Squeeze.

How To Back Up MySQL Databases With mylvmbackup On Ubuntu 12.10

mylvmbackup is a Perl script for quickly creating MySQL backups. 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.

How To Install A Streaming Audio Server With Icecast 2.3.3 On CentOS 6.3 x86_64 Linux

This tutorial explains creating your own streaming audio server with Icecast (OGG/MP3). Icecast was designed to stream any audio file if a appropiate streaming client is available. For OGG/Vorbis you can use ices and for MP3 icegenerator. Here is a small tutorial how to set up Icecast for streaming OGG/Vorbis and MP3.

Creating An NFS-Like Standalone Storage Server With GlusterFS 3.2.x On Ubuntu 12.10

This tutorial shows how to set up a standalone storage server on Ubuntu 12.10. Instead of NFS, I will use GlusterFS here. The client system will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.
