Eucalyptus Private Cloud SetupI t is not always poss ible for an organizat ion to m ove into the pu bl ic cloud. Most organizat ionsdo n ot want to or hesi tate moving their organization's data into the cloud. However, cloud

deployments can signi f icant ly bring do wn the operat ion costs o f an organizat ions.

To ful ly ut i l ize the resources, organizat ions h ave started dr i f t ing towards the private clous.

Acco rding to a Gartener Research, the market for p rivate clouds w i l l double by year 2015

leading to more private cloud deployments in organizat ion facing ineff ic ient and

underut i l izat ion o f resources.

There are already a num ber of open s ource cloud platforms that can con vertany datacenter into a private cloud withou t any expenses. Opensource projects l ike

Eucalyptus, Opennebula an Openstack are among th e most p romising open

source ini t iat ives bringing the industry s tandard cloud standards to the private cloud.Whi le

sett ing up p rivate clouds is not ro cket science, migrat ion from datatcenter to a private cloud

is a complex task.

In this post, I wi l l provide the setup for Eucaluptus Commmuntiy Edi t i ion , one of the most

popu lar open-source cloud computing framework.

The instal lat ion step fo r eucalyptus are brief ly described b elow.

Eucalyptus Front-end Installation

Installation from source: On a linux distribution, eucalyptus can be

easily installed from source.(Assuming eucalyptus source and dependencies

package are in home directory)

export VERSION=2.0.1

##### Install the eucalyptus dependencies.

apt-get install gcc make apache2-threaded-dev ant openjdk-6-jdklibvirt-dev libcurl4-dev dhcp3-server vblade apache2 unzip curlvlan bridge-utils libvirt-bin kvm sudo vtun##### Untar eucalyptus-source

Eucalyptus Node Controller Installation

To install from source, follow the steps used for installing eucalyptus.(or use the installation script for installation eucalyptus)

Tail the /var/log/eucalyptus/nc.log file to check if the eucalyptus-nc is

communicating with the eucalyptus-cc. The nc.log file updates continuously

with each line added when Eucalyptus-CC invokes describeResources() on the

Eucalyptus-NC.

At this point, the machine is configured with Xen and Eucalyptus NodeController.

The default user id and password is admin. Log in and change the password

and provide a valid email address at which you want to receive the

approval mails. Download the credentials file to the local machine. The

name of the file should be euca2-admin-x509.zip.

Source the .eucarc file from the zip.
