Part 1: Eucalyptus for building an Amazon EC2 compatible environment

This seriesof articles describes on how to deploy and use Eucalyptus- an Amazon EC2 compatible cloudplatform. The first part of the article guides you in setting up a Eucalyptus cloud platform for a testing

environment and the second part describes the internal detailsof the platform.What is Eucalyptus?

Eucalyptus is Amazons EC2/S3 API compatible cloud platform that was developed at the Department of

Computer Science, University of California, Santa Barbara. Eucalyptus Systems, Inc. was founded in

January 2009 to manage and continue development of Eucalyptus.

Although Eucalyptus has API compatibility with Amazons EC2/S3 services, unlike Amazons EC2 public

cloud, Eucalyptus is designed to provide a private cloud platform, and hence, some of the features of

Amazons EC2 public cloud (such as instance pricing) are not available with Eucalyptus.

Eucalyptus has been released as open source code under the GPLv3 license. For source commitments,

it is, however, necessary to accept and agree to the terms and conditions of Contributor License

Agreement (CLA). In addition, bug reports and patches are posted on the launchpad forums (https://

launchpad.net / eucalyptus) and community site ( http://open.eucalyptus.com)

This series of articles is based on version 1.6.2. Note that Version 2.0 was released on August 24th 2010.

Eucalyptus components

Eucalyptus must be installed on multiple hardware nodes. A Eucalyptus cloud setup, therefore,comprises various software units called components which are assigned different roles and are

categorized accordingly. The following diagram provides an overview of each component.

[Cloud Controller]

The Cloud Controller offers EC2-compatible interfaces as well as web management interfaces to users,

and it is responsible for managing the whole system. From here onwards, the Cloud Controller will be

referred to as CLC.

[Cluster Controller]

The Cluster Controller controls the network of Node Controllers and instances (virtual machines). From

here onwards, the Cluster Controller will be referred to as CC.

[Node Controller]

The Node Controller delegates the instructions from CC to the underlying hypervisor (Xen / KVM) to run

instances. From here onwards, the Node Controller will be referred to as NC.

[Storage Controller]

The Storage Controller offers EBS-style block-based storage to the instances. From here onwards, the

Storage Controller will be referred to as SC

[Walrus]Walrus offers S3-compatible interfaces and is also responsible for managing virtual machine images.

Installation RequirementsIn Eucalyptus, the availabilityof features depends on the configuration parameters and hardware setup.The following table, for instance, shows how the networking mode configuration parameter VNET_MODE

determines the availability of features.

The first part of this article omits details on feature availability for each networking mode. It focuses on

installing Eucalyptus cloud in MANAGED mode, since this mode is the most full-featured networking

mode.

Installation of Eucalyptus in MANAGED mode requires at least two physical machines (front-end and NC)

and a network hub. It is assumed that all Eucalyptus components except the NC (viz. CLC, CC, Walrus,SC) are co-located in a single machine referred to asthe front-end.Please note that the front-end should be located in the network segment which can be accessed from the

client machine as shown below. Moreover, make sure that a DHCP server is not in the network segment

shared by the NCs.

Installing the front-end (CLC/CC from here onwards) and NCs in the test environment does not require

high-spec machines, though for production environments, we recommend that you use machines with

decent hardware specifications. For reference, the following are the hardware specifications of the

servers used for testing purposes by the authors at work and home.

VT must be enabled to install Ubuntu Enterprise Cloud (UEC). However, in this series of articles thecloud setupwill assume a 64 bit CentOS 5.4 (Xen) that requires no VT-enabled CPUs. Installation and initial configuration of CentOS 5.4

During the installation of CentOS 5.4, disable the IPv6 support option and configure the network devices

as in the following diagram.

Pic01-01: Network devices configuration

As shown in the diagram, the authors prefer to exclude Desktop-Gnome packages not required for the

server installation. This is, however, a matter of personal choice, and we leave it to the readers to decide on whether to install these packages.

Modify the xen configuration parameters and restart the xend service in all the NC servers as follows.

{{{

EBS volumes as well as virtual machine instances consume loop-back devices. The followingcommands will increase the number of loop-back devices available.

{{{

# execute on both CLC/CC and NC

echo 'options loop max_loop=256' > /etc/modprobe.d/loop

for i in `seq 8 255`; do echo loop${i} >> /etc/udev/makedev.d/50-udev.nodes; done

}}}

The following commands will turn off servicesthat are unnecessary for setting up the Eucalyptus cloud.{{{

# Execute on both the CLC/CC and NC

chkconfig iptables off

chkconfig ip6tables off

#Execute on NC

chkconfig libvirtd off

}}}

After the OS has been configured, reboot the machine to make sure the above changes are reflected.

In addition, you should set up an NTP server to make sure all the servers that constitute the Eucalyptus

cloud and client machine system clocks are synchronized.

Installation and Configuration of Eucalyptus

The following packages are necessary for installing the CLC/CC server.

{{{
