==Objective==
+
==Cloud computing di Ubuntu==
  
−
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.

Ubuntu menyederhanakan komplexitas [[cloud computing]]. [[Cloud]] dapat dibuat untuk dapat di integrasikan dengan Amazon EC2 atau membuat private cloud dengan [[hardware]] sendiri. Edisi [[Server]] [[Ubuntu]] menolong kita untuk membuat dan mengontrol ke dua-nya.
  
 +
Sepertinya target Eucalyptus membuat sistem seperti Amazon EC2, Eucalyptus sendiri menggunakan Libvirt. Kelebihannya di [[clustering]] dan kompatibel dengan Amazon EC2.
  
 +
Kalau tidak perlu [[clustering]] naga-naganya virsh dan virt-manager masih lebih ringan dan mudah, sama-sama bisa kontrol Xen dan Qemu/KVM, pada akhirnya semua tergantung kebutuhan yang ada juga.

==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”.
 
−
 
 
−
[[Image:Bootscreen.png|center|200px|thumb]]
 
−
 
 
−
* The installer will detect if any other Eucalyptus components are present.
 
−
 
 
−
[[Image:Uec1.png|center|200px|thumb]]
 
−
 
 
−
* You can then choose which components to install, based on your chosen topology.
 
−
 
 
−
[[Image:Uec2.png|center|200px|thumb]]
 
−
 
 
−
* It will ask two other cloud-specific questions during the course of the install:
 
−
 
 
−
** Name of your cluster, e.g. cluster1.
 
−
 
 
−
[[Image:Uec3.png|center|200px|thumb]]
 
−
 
 
−
** 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.
 
−
 
 
−
[[Image:Uec4.png|center|200px|thumb]]
 
−
 
 
−
 
 
−
 
 
−
==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.
 
−
 
 
−
# Boot from the same ISO on the node(s)
 
−
# Select “Install Ubuntu Enterprise Cloud”
 
−
# It should detect the Cluster and preselect “Node” install for you
 
−
# Confirm the partitioning scheme
 
−
# 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:
 
−
 
 
−
# Public SSH keys have been exchanged properly
 
−
# The services are configured properly
 
−
# The services are publishing their existence
 
−
# The appropriate uec-component-listener is running
 
−
# 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.
 
−
 
 
−
 
 
−
===Publish===
 
−
 
 
−
Now start the publication services.
 
−
 
 
−
* Walrus Controller:
 
−
 
 
−
sudo start eucalyptus-walrus-publication
 
−
 
 
−
* Cluster Controller:
 
−
 
 
−
sudo start eucalyptus-cc-publication
 
−
 
 
−
* Storage Controller:
 
−
 
 
−
sudo start eucalyptus-sc-publication
 
−
 
 
−
* Node Controller
 
−
 
 
−
sudo start eucalyptus-nc-publication
 
−
 
 
−
 
 
−
===Start the Listener===
 
−
 
 
−
On the Cloud Controller and the Cluster Controller(s), run:
 
−
 
 
−
sudo start uec-component-listener
 
−
 
 
−
 
 
−
===Verify Registration===
 
−
 
 
−
cat /var/log/eucalyptus/registration.log

−
 
 
−
 
 
−
==STEP 5: Obtain Credentials==
 
−
 
 
−
After installing and booting the Cloud Controller, users of the cloud will need to retrieve their credentials. This can be done either through a web browser, or at the command line.
 
−
 
 
−
===From a Web Browser===
 
−
 
 
−
* From your web browser (either remotely or on your Ubuntu server) access the following URL:
 
−
 
 
−
https://<cloud-controller-ip-address>:8443/
 
−
 
 
−
Important! You must use a secure connection, so make sure you use "https" not "http" in your URL. You will get a security certificate warning. You will have to add an exception to view the page. If you do not accept it you will not be able to view the Eucalyptus configuration page.
 
−
 
 
−
* Use username 'admin' and password 'admin' for the first time login (you will be prompted to change your password).
 
−
* Then follow the on-screen instructions to update the admin password and email address.
 
−
* Once the first time configuration process is completed, click the 'credentials' tab located in the top-left portion of the screen.
 
−
* Click the 'Download Credentials' button to get your certificates
 
−
* Save them to ~/.euca
 
−
* Unzip the downloaded zipfile into a safe location (~/.euca)
 
−
 
 
−
unzip -d ~/.euca mycreds.zip
 
−
 
 
−
 
 
−
===From a Command Line===
 
−
 
 
−
Alternatively, if you are on the command line of the Cloud Controller, you can run:
 
−
 
 
−
mkdir -p ~/.euca
 
−
chmod 700 ~/.euca
 
−
cd ~/.euca
 
−
sudo euca_conf --get-credentials mycreds.zip
 
−
unzip mycreds.zip
 
−
ln -s ~/.euca/eucarc ~/.eucarc
 
−
cd -
 
−
 
 
−
 
 
−
===Extracting and Using Your Credentials===
 
−
 
 
−
Now you will need to setup EC2 API and AMI tools on your server using X.509 certificates.
 
−
 
 
−
* Install the required cloud user tools:
 
−
 
 
−
sudo apt-get install euca2ools
 
−
 
 
−
* To validate that everything is working correctly, get the local cluster availability details:
 
−
 
 
−
. ~/.euca/eucarc
 
−
euca-describe-availability-zones verbose
 
−

==STEP 6: Install an image from the store==
 
−
 
 
−
 
 
−
The following is by far the simplest way to install an image. However, advanced users may be interested in learning how to [[UECBundlingImages | Bundle their own image]].
 
−
 
 
−
The simplest way to add an image to UEC is to install it from the Image Store on the UEC web interface.
 
−
 
 
−
* Access the web interface at the following URL (Make sure you specify https):
 
−
 
 
−
https://<cloud-controller-ip-address>:8443/
 
−
 
 
−
* Enter your login and password (if requested, as you may still be logged in from earlier)
 
−
* Click on the Store tab
 
−
 
 
−
[[Image:Private-store-cr.png|center|200px|thumb]]
 
−
 
 
−
* Browse available images
 
−
* Click on install for the image you want
 
−
 
 
−
 
 
−
Once the image has been downloaded and installed, you can click on "How to run?" that will be displayed below the image button to view the command to execute to instantiate (start) this image. The image will also appear on the list given on the Image tab.
 
−
 
 
−
[[Image:Private-images-cr.png|center|200px|thumb]]
 
−
 
 
−
==STEP 7: Run an Image==
 
−
 
 
−
There are multiple ways to instantiate an image in UEC:
 
−
 
 
−
* Use the command line
 
−
* Use one of the UEC compatible management tools such as Landscape
 
−
* Use the ElasticFox extension to Firefox
 
−
 
 
−
Here we will describe the process from the command line:
 
−
 
 
−
* Before running an instance of your image, you should first create a keypair (ssh key) that you can use to log into your instance as root, once it boots. The key is stored, so you will only have to do this once. Run the following command:
 
−
 
 
−
if [ ! -e ~/.euca/mykey.priv ]; then
 
−
    mkdir -p -m 700 ~/.euca
 
−
    touch ~/.euca/mykey.priv
 
−
    chmod 0600 ~/.euca/mykey.priv
 
−
    euca-add-keypair mykey > ~/.euca/mykey.priv
 
−
fi
 
−
 
 
−
Note: You can call your key whatever you like (in this example, the key is called 'mykey'), but remember what it is called. If you forget, you can always run euca-describe-keypairs to get a list of created keys stored in the system.
 
−
 
 
−
* You must also allow access to port 22 in your instances:
 
−
 
 
−
euca-authorize default -P tcp -p 22 -s 0.0.0.0/0
 
−
 
 
−
* Next, you can create instances of your registered image:
 
−
 
 
−
euca-run-instances $EMI -k mykey -t m1.small
 
−
 
 
−
Note: If you receive an error regarding image_id, you may find it by viewing Images page or click "How to Run" on the Store page to see the sample command.
 
−
 
 
−
* The first time you run an instance, the system will be setting up caches for the image from which it will be created. This can often take some time the first time an instance is run given that VM images are usually quite large. To monitor the state of your instance, run:
 
−
 
 
−
watch -n5 euca-describe-instances
 
−
 
 
−
In the output, you should see information about the instance, including its state. While first-time caching is being performed, the instance's state will be 'pending'.
 
−
 
 
−
* When the instance is fully started, the above state will become 'running'. Look at the IP address assigned to your instance in the output, then connect to it:
 
−
 
 
−
IPADDR=$(euca-describe-instances | grep $EMI | grep running | tail -n1 | awk '{print $4}')
 
−
ssh -i ~/.euca/mykey.priv ubuntu@$IPADDR
 
−
 
 
−
* And when you are done with this instance, exit your SSH connection, then terminate your instance:
 
−
 
 
−
INSTANCEID=$(euca-describe-instances | grep $EMI | grep running | tail -n1 | awk '{print $2}')
 
−
euca-terminate-instances $INSTANCEID
 
−
 
 
−
 
 
−

==Glossary==
 
−
 
 
−
The Ubuntu Enterprise Cloud documentation uses terminology that might be unfamiliar to some readers. This page is intended to provide a glossary of such terms and acronyms.
 
−
 
 
−
* Cloud - A federated set of physical machines that offer computing resources through virtual machines, provisioned and recollected dynamically.
 
−
* Cloud Controller (CLC) - Eucalyptus component that provides the web UI (an https server on port 8443), and implements the Amazon EC2 API. There should be only one Cloud Controller in an installation of UEC. This service is provided by the Ubuntu eucalyptus-cloud package.
 
−
* Cluster - A collection of nodes, associated with a Cluster Controller. There can be more than one Cluster in an installation of UEC. Clusters are sometimes physically separate sets of nodes. (e.g. floor1, floor2, floor2).
 
−
* Cluster Controller (CC) - Eucalyptus component that manages collections of node resources. This service is provided by the Ubuntu eucalyptus-cc package.
 
−
* EBS - Elastic Block Storage. http://aws.amazon.com/ebs/
 
−
* EC2 - Elastic Compute Cloud. Amazon's pay-by-the-hour, pay-by-the-gigabyte public cloud computing offering.
 
−
* EKI - Eucalyptus Kernel Image.
 
−
* EMI - Eucalyptus Machine Image.
 
−
* ERI - Eucalyptus Ramdisk Image.
 
−
* Eucalyptus - Elastic Utility Computing Architecture for Linking Your Programs To Useful Systems. An open source project originally from the University of California at Santa Barbara, now supported by Eucalyptus Systems, a Canonical Partner.
 
−
* Front-end - Physical machine hosting one (or more) of the high level Eucalyptus components (cloud, walrus, storage controller, cluster controller).
 
−
* Node - A node is a physical machine that's capable of running virtual machines, running a node controller. Within Ubuntu, this generally means that the CPU has VT extensions, and can run the KVM hypervisor.
 
−
* Node Controller (NC) - Eucalyptus component that runs on nodes which host the virtual machines that comprise the cloud. This service is provided by the Ubuntu package eucalyptus-nc.
 
−
* S3 - Simple Storage Service. Amazon's pay-by-the-gigabyte persistent storage solution for EC2. http://aws.amazon.com/s3/
 
−
* Storage Controller (SC) - Eucalyptus component that manages dynamic block storage services (EBS). Each 'cluster' in a Eucalyptus installation can have its own Storage Controller. This component is provided by the 'eucalyptus-sc' package.
 
−
* UEC - Ubuntu Enterprise Cloud. Ubuntu's cloud computing solution, based on Eucalyptus.
 
−
* VM - Virtual Machine.
 
−
* VT - Virtualization Technology. An optional feature of some modern CPUs, allowing for accelerated virtual machine hosting.
