CentOS 5.9: ovvero RHEL 5.9

CentOS è una distribuzione Linux al 100% compatibile con Red Hat Enterprise Linux e perfettamente adeguata alle direttive di Red Hat riguardante la redistribuzione del proprio codice. CentOS è pensate per persone che hanno bisogno di sistemi enterprise molto stabili ma senza dover sostenere il costo di supporto e certificazione. La versione è pienamente compatibile con RHEL 5.9 e integra pacchetti sia per il ramo server che client.

Automatic File Replication Across 2 Storage Servers With GlusterFS On CentOS 6.3

This tutorial shows how to set up a high-availability storage with two storage servers (CentOS 6.3) 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 (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.

Using ATA Over Ethernet (AoE) On CentOS 6.3 (Initiator And Target)

This guide explains how you can set up an AoE target and an AoE initiator (client), both running CentOS 6.3. AoE stands for "ATA over Ethernet" and is a storage area network (SAN) protocol which allows AoE initiators to use storage devices on the (remote) AoE target using normal ethernet cabling. "Remote" in this case means "inside the same LAN" because AoE is not routable outside a LAN (this is a major difference compared to iSCSI). To the AoE initiator, the remote storage looks like a normal, locally-attached hard drive.

Abilitare gli aggiornamenti automatici in Centos 6 e Red Hat 6

In un precedente articolo abbiamo visto come Abilitare gli aggiornamenti automatici di sicurezza in Debian/Ubuntu , lo uso questa metodo sulla mia VPS Debian e devo dire che grazie a questo ho dimenticato le preoccupazioni per la sicurezza grazie agli aggiornamenti automatici, ma forse voi avete una Red Hat 6 o Centos 6 e volete anche voi dormire tranquilli? Non c’è nessun problema, oggi vedremo come ottenere lo stesso risultato su una macchina Centos 6.

Creating Virtual RedHat/CentOS/Fedora Appliances For KVM With BoxGrinder

BoxGrinder is a tool that allows you to build virtual machines (with RedHat, CentOS, Scientific Linux or Fedora as the OS) for multiple virtualization techniques. Currently it supports KVM, VMware, Amazon EC2, VirtualBox, and VirtualPC. This tutorial shows how to use BoxGrinder to create a CentOS 6 KVM guest on Fedora 17 and also how to deploy it to a remote KVM host.

Serving CGI Scripts With Nginx On CentOS 6.3

This tutorial shows how you can serve CGI scripts (Perl scripts) with nginx on CentOS 6.3. While nginx itself does not serve CGI, there are several ways to work around this. I will outline two solutions: the first is to proxy requests for CGI scripts to Thttpd, a small web server that has CGI support, while the second solution uses a CGI wrapper to serve CGI scripts.

Virtualization With KVM On A CentOS 6.3 Server

This guide explains how you can install and use KVM for creating and running virtual machines on a CentOS 6.3 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.

Virtualization With Xen On CentOS 6.3 (x86_64) (Paravirtualization & Hardware Virtualization)

This tutorial provides step-by-step instructions on how to install Xen (version 4.1.x) on a CentOS 6.3 (x86_64) system. Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other.

Installing Lighttpd With PHP5 (PHP-FPM) And MySQL Support On CentOS 6.3

Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on a Centos 6.3 server with PHP5 support (through PHP-FPM) and MySQL support. PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites. I use PHP-FPM in this tutorial instead of Lighttpd's spawn-fcgi.

The Perfect Server - CentOS 6.3 x86_64 (nginx, Dovecot, ISPConfig 3)

This tutorial shows how to prepare a CentOS 6.3 x86_64 server 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: nginx web server, Postfix mail server, MySQL, BIND nameserver, PureFTPd, SpamAssassin, ClamAV, Mailman, and many more. Since version 3.0.4, ISPConfig comes with full support for the nginx web server in addition to Apache; this tutorial covers the setup of a server that uses nginx, not Apache.
