Ubuntu Enterprise Cloud

Objective

From this Tutorial you will learn how to install, configure, register and perform several operations on a basic UEC setup that results in a cloud with a one controller "front-end" and one or several node(s) for running Virtual Machine (VM) instances. You will also use examples to help get you started using your own private compute cloud.

Download

• Download iso Ubuntu Server dari

STEP 1: Prerequisites

To deploy a minimal cloud infrastructure, you’ll need at least two dedicated systems:

• a front end
• one or more node(s)

The following are recommendations, rather than fixed requirements. However, our experience in developing this documentation indicated the following suggestions.

Front End

Use the following table for a system that will run one or more of:

• the cloud controller (clc)
• the cluster controller (cc)
• walrus (the S3-like storage service)
• the storage controller (sc)

Hardware	Minimum	Suggested	Notes
CPU	1GHz	2 x 2GHz	for an all-in-one front end, it helps to have at least a dual core processor
Memory	2GB	4GB	the Java web front end benefits from lots of available memory
Disk	5400rpm IDE	7200rpm SATA	slower disks will work, but will yield much longer instance startup times
Disk Space	40GB	200GB	40GB is only enough space for only a single image, cache, etc., Eucalyptus does not like to run out of disk space
Networking	100Mbps	1000Mbps	machine images are hundreds of MB, and need to be copied over the network to nodes

Node(s)

The other system(s) are nodes, which will run:

• the node controller (nc)

These systems will actually run the instances. You will need one or more systems with:

Hardware	Minimum	Suggested	Notes
CPU	VT extensions	VT, 64-bit, Multicore	64-bit can run both i386, and amd64 instances; by default, Eucalyptus will only run 1 VM per CPU core on a Node
Memory	1GB	4GB	additional memory means more, and larger guests
Disk	5400rpm IDE	7200rpm SATA or SCSI	Eucalyptus nodes are disk-intensive; I/O wait will likely be the performance bottleneck
Disk Space	40GB	100GB	images will be cached locally, Eucalyptus does not like to run out of disk space
Networking	100Mbps	1000Mbps	machine images are hundreds of MB, and need to be copied over the network to nodes

STEP 2: Install the Cloud/Cluster/Storage/Walrus Front End Server

• Download the 10.04 Server ISO
• When you boot, select “Install Ubuntu Enterprise Cloud”.

• The installer will detect if any other Eucalyptus components are present.

• You can then choose which components to install, based on your chosen topology.

• It will ask two other cloud-specific questions during the course of the install:

• • Name of your cluster, e.g. cluster1.

• • A range of public IP addresses on the LAN that the cloud can allocate to instances, e.g. 192.168.1.200-192.168.1.249.

STEP 3: Install the Node Controller(s)

The node controller install is even simpler. Just make sure that you are connected to the network on which the cloud/cluster controller is already running.

1. Boot from the same ISO on the node(s)
2. Select “Install Ubuntu Enterprise Cloud”
3. It should detect the Cluster and preselect “Node” install for you
4. Confirm the partitioning scheme
5. The rest of the installation should proceed uninterrupted; complete the installation and reboot the node

STEP 4: Register the Node(s)

As of Ubuntu 10.04 LTS, all component registration should be automatic, assuming:

1. Public SSH keys have been exchanged properly
2. The services are configured properly
3. The services are publishing their existence
4. The appropriate uec-component-listener is running
5. Verify Registration.

Steps a to e should only be required if you're using the UEC/PackageInstall method. Otherwise, if you are following the UEC/CDInstall method, these steps should already be completed automatically for you, and therefore you can skip a to e.

Exchange Public SSH Keys

The Cloud Controller's eucalyptus user needs to have SSH access to the Walrus Controller, Cluster Controller, and Storage Controller as the eucalyptus user.

Install the Cloud Controller's eucalyptus user's public ssh key by:

• On the target controller, temporarily set a password for the eucalyptus user:

sudo passwd eucalyptus

• Then, on the Cloud Controller:

sudo -u eucalyptus ssh-copy-id -i /var/lib/eucalyptus/.ssh/id_rsa.pub eucalyptus@<IP_OF_NODE>

• You can now remove the password of the eucalyptus account on the target controller, if you wish:

sudo passwd -d eucalyptus

Configure the Services

On the Cloud Controller:

• For the Cluster Controller Registration:
  • Define the shell variable CC_NAME in /etc/eucalyptus/eucalyptus-cc.conf
  • Define the shell variable CC_IP_ADDR in /etc/eucalyptus/eucalyptus-ipaddr.conf, as a space separated list of one or more IP addresses.

• For the Walrus Controller Registration:
  • Define the shell variable WALRUS_IP_ADDR in /etc/eucalyptus/eucalyptus-ipaddr.conf, as a single IP address.

On the Cluster Controller:

• For Storage Controller Registration:
  • Define the cluster name in the shell variable CC_NAME in /etc/eucalyptus/eucalyptus-cc.conf
  • Define the shell variable SC_IP_ADDR in /etc/eucalyptus/eucalyptus-ipaddr.conf, as a space separated list of one or more IP addresses.
