Setting up your OpenStack Havanafor testing and development

Workflow

● Install OpenStack through DevStack

● Configure the network

● Configure OpenStack to auto-assign IPs

● Add OpenStack to Mist.io and launch VMs

Install OpenStack with DevStack

Download DevStack through gitsudo apt-get install git

git clone https://github.com/openstack-dev/devstack.git

cp samples/localrc localrc

Configure the network

Edit localrc and configure the network by addingHOST_IP: our public ip

FLAT_INTERFACE: The best way is to assign br100 interface to it

FLOATING_RANGE: 159.253.138.184/29

PUBLIC_INTERFACE=bond1 (this is the interface for our internal network used by OpenStack services to communicate with each other)

Finish the installation

Finish the OpenStack installationcd devstack; ./stack.sh

To auto assign ips from the floating ips pool we have to configure it

sudo nova-manage floating create --pool pool_auto_assign --ip_range 159.253.138.184/29

Automate IP assignment

Set auto_assign_floating_ip = True in nova.confdefault_floating_pool = pool_auto_assignfloating_range = 159.253.138.184/29auto_assign_floating_ip = True

Restart nova-network and you’re set!

Add OpenStack to Mist.io

Fill in your username, password,

tenant name and Auth URL

Enjoy!

We can now create, destroy, reboot and monitor our virtual machines through Mist.io
