OpenVZ is container-based virtualization for Linux. OpenVZ creates multiple secure, isolated containers (otherwise known as VE or VPS) on a single physical server enabling better server utilization and ensuring that applications do not conflict. Each container performs and executes exactly like a stand-alone server; a container can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.

Step 1. Installation:
An OpenVZ kernel and the vzctl and vzquota packages are available in the Debian Squeeze repositories, so we can install them as follows:

apt-get install linux-image-openvz-686  vzctl  vzquota

Step 2. Create a symlink from /var/lib/vz to /vz to provide backward compatibility:

ln -s /var/lib/vz /vz

Step 3. Open with your favorite editor (eg: nano, vim) /etc/sysctl.conf and edit as following :

net.ipv4.conf.default.proxy_arp = 0
kernel.sysrq = 1
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0

After you’ve edited /etc/sysctl.conf file run:

sysctl -p

The Debian project is pleased to announce the first update of its stable distribution Debian 6.0 (codename squeeze).
This update mainly adds corrections for security problems to the stable release, along with a few adjustment to serious problems.

Please note that this update does not constitute a new version of Debian 6.0 but only updates some of the packages included. There is no need to throw away 6.0 CDs or DVDs but only to update via an up-to-date Debian mirror after an installation, to cause any out of date packages to be updated.

Those who frequently install updates from won’t have to update many packages and most updates from are
included in this update.

New CD and DVD images containing updated packages and the regular installation media accompanied with the package archive respectively will be available soon at the regular locations.

Upgrading to this revision online is usually done by pointing the aptitude (or apt) package tool (see the sources.list(5) manual page) to one of Debian’s many FTP or HTTP mirrors. A comprehensive list of mirrors is available at:

Virtual hosts are used to run more than one web site on a single machine.
Virtual hosts can be “IP-based”, meaning that you have a different IP address for every web site, or “name-based”, meaning that you have multiple names running on each IP address.

I want to show you one of mine scripts for easy create virtual hosts in Debian Squeeze or ubuntu.


# Check if is root
if [ "$UID" -ne "$ROOT_UID" ]
echo “You must be root to run this script.”

if [ -n "$1" ]
echo “You must provide a full domain name for this site, i.e. ‘’ ”
echo -n “Run this script like ./script .”

#Create document root site folder
mkdir -p $WWW_ROOT/$DOMAIN
