Configuring Eucalyptus 3-devel

In my last entry, I explained how to checkout eucalyptus 3-devel and build it from source on Fedora 16.  This entry will explain how to follow that process with configuration and initialization of a single node cloud.

1) Configure environment variables.

export EUCALYPTUS=/opt/eucalyptus
export PATH=$PATH:$EUCALYPTUS/usr/sbin

2) Configure eucalyptus.conf -- Since this is a single node install on a network with DHCP, I am using SYSTEM mode for networking, which is the default.

EUCALYPTUS="/opt/eucalyptus"

HYPERVISOR="kvm"

USE_VIRTIO_DISK="1"
USE_VIRTIO_NET="1"
INSTANCE_PATH="/opt/eucalyptus/instances"
VNET_BRIDGE="br0"


3)  Set up proper file and directory permissions in the installed tree:

su -c "euca_conf --setup"

4) Initialize the database:

euca_conf --initialize

5) Create a bridge device and associate your primary NIC (this is specific to SYSTEM mode):

/etc/sysconfig/network-scripts/ifcfg-br0:
DEVICE=br0
TYPE=Bridge
BOOTPROTO=dhcp
ONBOOT=yes
DELAY=0
NM_CONTROLLED=no



/etc/sysconfig/network-scripts/ifcfg-em1:
DEVICE="em1"
ONBOOT=yes
BRIDGE=br0
NM_CONTROLLED=nothen restart your network

6) UPDATE: Start the CLC before getting credentials.

su -c "/opt/eucalyptus/etc/init.d/eucalyptus-cloud start"

7) Get credentials and source them:

euca_conf --get-credentials admin.zip

unzip admin.zip

source eucarc

8) Start the cloud components and register services:

euca_conf --register-walrus -H <hostname> -C walrus -P walrus

euca_conf --register-sc -H <hostname> -C SC_251 -P PARTI00

euca_conf --register-cluster -H <hostname> -C CC_251 -P PARTI00

su -c "/opt/eucalyptus/etc/init.d/eucalyptus-cc start"

euca_conf --register-nodes <hostname>

su -c "/opt/eucalyptus/etc/init.d/eucalyptus-nc start"

At this point, you should have a running cloud.  To verify the components:

euca-describe-walruses ; euca-describe-storage-controllers ; euca-describe-clusters

You should see something like:

WALRUS    walrus    walrus             192.168.51.251     ENABLED    {}
STORAGECONTROLLER    PARTI00  SC_251   192.168.51.251     ENABLED    {}
CLUSTER    PARTI00            CC_251   192.168.51.251     ENABLED    {}

And to ensure that the node controller is advertising resources:

euca-describe-availability-zones verbose

which shows:

AVAILABILITYZONE    PARTI00    192.168.51.251 arn:euca:eucalyptus:PARTI00:cluster:CC_251/
AVAILABILITYZONE    |- vm types    free / max   cpu   ram  disk
AVAILABILITYZONE    |- m1.small    0004 / 0004   1    128     2
AVAILABILITYZONE    |- c1.medium    0002 / 0002   1    256     5
AVAILABILITYZONE    |- m1.large    0001 / 0001   2    512    10
AVAILABILITYZONE    |- m1.xlarge    0000 / 0000   2   1024    20
AVAILABILITYZONE    |- c1.xlarge    0000 / 0000   4   2048    20

That's all for my second post.   Comments and corrections welcome.  See you on #eucalyptus !
