Installing OpenStack on Debian Wheezy single node

Installing OpenStack on Debian Wheezy single node

In this article i will describe step by step how to do Installing OpenStack on Debian Wheezy single node
 

The First thing you need to do is adding the necessary repositories to your /etc/apt/sources.list

deb http://cdn.debian.net/debian/ wheezy main contrib non-free
deb-src http://cdn.debian.net/debian/ wheezy main contrib non-free
deb http://cdn.debian.net/debian/ sid main contrib non-free
deb-src http://cdn.debian.net/debian/ sid main contrib non-free

deb http://security.debian.org/ wheezy/updates main contrib non-free
deb-src http://security.debian.org/ wheezy/updates main contrib non-free

deb http://cdn.debian.net/debian/ squeeze-updates main contrib non-free
deb-src http://cdn.debian.net/debian/ squeeze-updates main main contrib non-free

Then upgrade your repositories by running:

apt-get update && apt-get upgrade -y

After this install the needed packages from new added repositories:

apt-get install mysql-server rabbitmq-server
apt-get install memcached keystone python-keystone python-keystoneclient euca2ools
apt-get install nova-api nova-api-metadata nova-cert nova-common nova-compute nova-compute-kvm nova-console nova-network nova-objectstore nova-scheduler nova-volume nova-xvpvncproxy glance glance-api glance-common glance-registry python-glance
apt-get install python-nova python-novaclient openstack-dashboard openstack-dashboard-apache python-openstack-common
apt-get install iscsitarget iscsitarget-dkms

enable iscsi by editing /etc/default/iscsitarget value:

ISCSITARGET_ENABLE=true

and create a lvm volume for your nova instances with right path of your empty second disk/partition:

pvcreate /dev/sdb
vgcreate nova-volumes /dev/sdb

in mysql config /etc/mysql/my.cnf edit your address binding value to:

bind-address = 127.0.0.1

configure your network interfaces in /etc/network/interfaces:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet static
address 5.0.0.2
netmask 255.255.255.255
gateway 5.0.0.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 8.8.8.8 8.8.4.4
dns-search bcnx.de

allow-hotplug eth1
iface eth1 inet manual
up ifconfig $IFACE 0.0.0.0 up
up ifconfig $IFACE promisc
down ifconfig $IFACE down

Safe your /etc/nova/nova.conf and replace it with following:

add your fixed network to database:

nova-manage network create private --fixed_range_v4=172.16.100.0/24 --network_size=256

and then your public ip range:

nova-manage floating create --ip_range=5.0.0.0/24

to use the nova api command line add this to your .bashrc in your home directory:

export OS_TENANT_NAME=openstack
export OS_USERNAME=admin
export OS_PASSWORD=REPLACEwithyourPASSWORD
export OS_AUTH_URL="http://127.0.0.1:5000/v2.0/"
export OS_AUTH_STRATEGY=keystone
export SERVICE_TOKEN=REPLACEwithyourADMINtoken
export SERVICE_ENDPOINT=http://127.0.0.1:35357/v2.0/
export S3_URL="http://127.0.0.1:3333"

and restart your system/services.
after this check if your openstack services running properly:

nova-manage service list

Finally you need to create your tenants, user, roles and endpoints.
I am not going to refer to it in this post.
Create the service users like described here: Configuring Service
or here: Identity management
