Overview

This tutorial covers UEC installation by adding the Eucalyptus packages to previously installed Ubuntu 9.10 servers where you want to have separate servers for the following services:

• 1 Cloud Controller (CLC - eucalyptus-cloud) server
• 1 Walrus Controller (WS3 - eucalyptus-walrus) server
• N Cluster Controller (CC - eucalyptus-cc) + Storage Controller (EBS - eucalyptus-sc) servers
• N Node Controller (NC - eucalyptus-nc) servers on a dedicated network connected to on of the CC+EBS server

Objective

From this tutorial, you will learn how to install, configure, register and perform several operations on a advanced UEC setup that results in a cloud as described in the above section. This topology is recommended if you would like to build a generic purpose scalable cloud. Our current testing indicate that a given cluster should limit itself to the management of up to 250 instances.

Tutorial

STEP 1: Prerequisites

To deploy a minimal cloud infrastructure, you’ll need at least 4 dedicated systems:

• 1 CLC
• 1 WS3
• 1 CC + EBS
• 1 NC

<<Include(UEC/SystemRequirementsSeparate)>>

STEP 2a: Install the Cloud Controller Server

<<Include(UEC/BaseServerIntall)>>

1. Install the eucalyptus-cloud package on the server

sudo apt-get install eucalyptus-cloud

Answer debconf's questions as follow:

• Configure postfix for internet delivery

1. Make sure process eucalyptus-cloud is running

ps -ef | grep eucalyptus-cloud

STEP 2b: Install the Cluster Controller Server(s)

<<Include(UEC/BaseServerIntall)>>

1. Install the eucalyptus-cc and eucalyptus-sc packages on the server

sudo apt-get install eucalyptus-cc eucalyptus-sc

Answer debconf's questions as follow:

• Configure postfix for internet delivery
• Name your cluster
• e.g. cluster1
• Add a list of available IP addresses on your external (public) network
• e.g. 192.168.1.200-192.168.1.249

1. Configure the second network interface

sudo apt-get install bridge-utils vtun
interface=eth1
bridge=br1
sudo sed -i "s/^iface $interface inet \(.*\)$/iface $interface inet manual\n\nauto $bridge\niface $bridge inet \1/" /etc/network/interfaces
sudo tee -a /etc/network/interfaces <<EOF
        bridge_ports $interface
        bridge_fd 9
        bridge_hello 2
        bridge_maxage 12
        bridge_stp off
EOF
sudo /etc/init.d/networking restart

1. Edit /etc/eucalyptus/eucalyptus.conf so that

• br1 is the internal (private) interface and the bridge interface
• eth0 the external (public) interface
• you provide the correct address of the cloud controller (CLC) that you just installed in place of <CLC_ipaddress>

by editing the following 3 variables, the third one (VNET_CLOUDIP) needing to be added manually:

VNET_PUBINTERFACE="eth0"
VNET_PRIVINTERFACE="br1"
VNET_CLOUDIP="<CLC_ipaddress>"

1. Edit /etc/eucalyptus/eucalyptus-ipaddr.conf so that the following variable are set to the internal (private) ip address of the server

CC_IP_ADDR="<CC_ipaddress>"
SC_IP_ADDR="<CC_ipaddress>"

1. Restart the service with a config reinitialisation

sudo restart eucalyptus-cc CLEAN=1
sudo restart eucalyptus-sc

1. Make sure processes eucalyptus-cc and eucalyptus-sc are running

ps -ef | grep eucalyptus-

STEP 2c: Install the Walrus Controller Server

<<Include(UEC/BaseServerIntall)>>

1. Install the eucalyptus-walrus package on the server

sudo apt-get install eucalyptus-walrus

STEP 3: Install and Configure the Node Controller(s)

Installing the Eucalyptus Node Service on a running Ubuntu system consists of doing the following on one or more systems: <<Include(UEC/BaseServerIntall)>> <<Include(UEC/NodeInstallationSeparate)>>

STEP 4: Register the Cluster, Storage, and Walrus Servers

The cloud controller must be aware the storage (SC, WS3) and of the clusters controllers, so you will need to allow password-less authentication between the CLC and the other server and then register them.

SSH Key Authentication Setup

<<Include(UEC/SSHKeyAuthSetup)>>

Registration

To register the controllers on the CLC:

1. Register the WS3 server:

sudo euca_conf --no-rsync --register-walrus <WS3_ipaddresss>

1. Then for each of your CC:

sudo euca_conf --no-rsync --register-cluster <CC_name> <CC_ipaddress>
sudo euca_conf --no-rsync --register-sc <CC_name> <CC_ipaddress>

Note: If you get prompted for passwords, or receive errors from scp, you may need to revisit the key synchronization instructions at SSH Key Authentication Setup

1. Then edit the /etc/eucalyptus/eucalyptus-ipaddr.conf to fill the 3 following variables appropriately with the ip address of the respective service, replacing the "$addr" value. If you have multiple CC and SC, you can specify multiple IP addresses separating them with a space.

CC_IP_ADDR="$addr"
WALRUS_IP_ADDR="$addr"
SC_IP_ADDR="$addr"

1. Finally restart the eucalyptus service on the CLC

 sudo service eucalyptus restart

Verify Registration

Verify that the registration process was successful by running the following commands

sudo euca_conf --list-walruses
sudo euca_conf --list-scs
sudo euca_conf --list-clusters

STEP 5: Register the Node(s)

<<Include(UEC/NodeRegistration)>>

STEP 6: Obtain Credentials

<<Include(UEC/Credentials)>>

STEP 7: Install an image from the store

<<Include(UEC/GetAnImageFromStore)>>

STEP 8: Run an Image

<<Include(UEC/RunningImages)>>
