The Ubuntu developers are moving quickly to bring you the latest and greatest software the Open Source Community has to offer. This is the Ubuntu 9.10 beta release, which brings a host of exciting new features. Note: This is a beta release. Do not install it on production machines. The final stable version will be released on October 29th, 2009. Full Story
VBoxHeadless - Running Virtual Machines With VirtualBox 3.1.x On A Headless Fedora 12 Server
VBoxHeadless - Running Virtual Machines With VirtualBox 3.1.x On A Headless Fedora 12 Server
This guide explains how you can run virtual machines with Sun VirtualBox 3.1.x
on a headless Fedora 12 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.
Distributed Replicated Storage Across Four Storage Nodes With GlusterFS On Fedora 12
Distributed Replicated Storage Across Four Storage Nodes With GlusterFS On Fedora 12
This tutorial shows how to combine four single storage servers (running Fedora 12) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network.
If you lose one server from replication1 and one from replication2,
the distributed volume continues to work. The client system (Fedora 12
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 Lighttpd With PHP5 And MySQL Support On Fedora 12
Installing Lighttpd With PHP5 And MySQL Support On Fedora 12
Lighttpd is a secure, fast, standards-compliant web server designed
for speed-critical environments. This tutorial shows how you can
install Lighttpd on a Fedora 12 server with PHP5 support (through
FastCGI) and MySQL support.

Using WebDAV With ISPConfig 3 On Ubuntu 9.10
This guide explains how to set up and use WebDAV on a web site
created with ISPConfig 3 on an Ubuntu 9.10 server. WebDAV stands for Web-based Distributed Authoring and Versioning
and is a set of extensions to the HTTP protocol that allow users to
directly edit files on the Apache server so that they do not need to be
downloaded/uploaded via FTP. Of course, WebDAV can also be used to
upload and download files.
Fully Utilizing Your X-Core CPU
Almost all systems sold nowadays have at least a dual-core CPU, even
triple- or quad-cores are getting cheaper and getting standard in the
near future. But how to utilize your shiny x-core to it's full
potential, with applications that are only utilizing one core ? With
Linux, which has strong multitasking capabilities as all unixoid
operating systems, there is an easy possibility to parallelize tasks
which are normally only using one core of an x-core CPU.
High-Availability Storage With GlusterFS On Fedora 12 - Automatic File Replication (Mirror) Across Two Storage Servers
High-Availability Storage With GlusterFS On Fedora 12 - Automatic File Replication (Mirror) Across Two Storage Servers
This tutorial shows how to set up a high-availability storage with two storage servers (Fedora 12) that use GlusterFS.
Each storage server will be a mirror of the other storage server, and
files will be replicated automatically across both storage servers. The
client system (Fedora 12 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.
Changing From SquirrelMail To RoundCube On Your ISPConfig3 Server
Changing From SquirrelMail To RoundCube On Your ISPConfig3 Server
This tutorial has been created for those who have installed The Perfect Server - CentOS 5.4 x86_64 [ISPConfig 3]
and do not like SquirrelMail as webmail client. Here’s a guide to
replace SquirrelMail with RoundCube, which is more visually attractive
and easier to manage for our clients.
Server Monitoring With munin And monit On Debian Lenny
Server Monitoring With munin And monit On Debian Lenny
In this article I will describe how you can monitor your Debian
Lenny server with munin and monit. munin produces nifty little graphics
about nearly every aspect of your server (load average, memory usage,
CPU usage, MySQL throughput, eth0 traffic, etc.) without much
configuration, whereas monit checks the availability of services like
Apache, MySQL, Postfix and takes the appropriate action such as a
restart if it finds a service is not behaving as expected. The
combination of the two gives you full monitoring: graphics that lets
you recognize current or upcoming problems (like "We need a bigger
server soon, our load average is increasing rapidly."), and a watchdog
that ensures the availability of the monitored services.
