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. http://www.ziobudda.net/notizie/virtualization-kvm-centos-64-server#comments HowtoForge centos kvm Libvirt Virt-Manager virtual machine virtualization Thu, 18 Apr 2013 10:30:33 +0200 falko 219072 at http://www.ziobudda.net http://www.ziobudda.net/notizie/perfect-server-centos-64-x8664-nginx-dovecot-ispconfig-3 This tutorial shows how to prepare a CentOS 6.4 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. http://www.ziobudda.net/notizie/perfect-server-centos-64-x8664-nginx-dovecot-ispconfig-3#comments HowtoForge amavisd bind centos clamav dovecot fpm ispconfig lemp mysql nginx php postfix pureftpd spamassassin Tue, 02 Apr 2013 11:43:17 +0200 falko 218763 at http://www.ziobudda.net http://www.ziobudda.net/notizie/virtual-usersdomains-postfix-courier-mysql-squirrelmail-centos-63 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. http://www.ziobudda.net/notizie/virtual-usersdomains-postfix-courier-mysql-squirrelmail-centos-63#comments HowtoForge amavisd centos clamav courier mysql postfix spamassassin squirrelmail Sun, 24 Mar 2013 11:12:09 +0100 falko 218602 at http://www.ziobudda.net http://www.ziobudda.net/notizie/perfect-server-centos-64-x8664-apache2-dovecot-ispconfig-3 This tutorial shows how to prepare a CentOS 6.4 x86_64 server for the installation of ISPConfig 3, and how to install ISPConfig 3.

This feature works with PHP-FPM (starting with PHP 5.3) and FastCGI (all PHP 5.x versions). This tutorial shows how to build PHP 5.3 and PHP 5.4 as a PHP-FPM and a FastCGI version on a CentOS 6.3 server. These PHP versions can be used together with the default PHP (installed through yum) in ISPConfig. http://www.ziobudda.net/notizie/using-multiple-php-versions-phpfpm-fastcgi-ispconfig-3-centos-63#comments HowtoForge apc centos fastcgi ispconfig pear pecl php php-fpm Thu, 14 Mar 2013 10:59:16 +0100 falko 218409 at http://www.ziobudda.net http://www.ziobudda.net/notizie/selinux-impedisce-la-lettura-dei-siti-web Benvenuti ad un’altra putanta su SELinux il Super Sistema di Sicureza che blocca anche se stesso. L’altro giorno dopo aver configurato alcuni siti web su un server. Restartando il servizio Apache mi sono accorto che andando su i nuovi siti mi dava Access Denied. Ho pensato subito ad un problema di permessi ( owner / group ) ma questi erano settati giusti. Allora mi è sorto subito il dubbio dello zambino di SELinux. http://www.ziobudda.net/notizie/selinux-impedisce-la-lettura-dei-siti-web#comments *BSD centos linux SELinux Thu, 31 Jan 2013 00:21:30 +0100 lightuono 217622 at http://www.ziobudda.net http://www.ziobudda.net/notizie/apache-modproxy-%E2%80%98error-13permission-denied%E2%80%99-error-su-centos Oggi a lavoro dopo aver configurato il Proxy_ajp tra Apache e JBoss il VirtualHost non ne voleva proprio di partire.

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. http://www.ziobudda.net/notizie/centos-59-ovvero-rhel-59#comments Distribuzioni centos RHEL Sat, 19 Jan 2013 11:10:36 +0100 ice00 217420 at http://www.ziobudda.net http://www.ziobudda.net/notizie/automatic-file-replication-across-2-storage-servers-glusterfs-centos-63 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. http://www.ziobudda.net/notizie/automatic-file-replication-across-2-storage-servers-glusterfs-centos-63#comments HowtoForge centos cluster filesystem gluster glusterfs high-availability storage Sun, 23 Dec 2012 15:09:48 +0100 falko 217066 at http://www.ziobudda.net http://www.ziobudda.net/notizie/using-ata-over-ethernet-aoe-centos-63-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. http://www.ziobudda.net/notizie/using-ata-over-ethernet-aoe-centos-63-initiator-and-target#comments HowtoForge aoe ata over ethernet centos filesystem storage Sun, 16 Dec 2012 12:46:01 +0100 falko 216957 at http://www.ziobudda.net
