How to Install OpenStack on VirtualBox via DevStack

DevStack Setup

I would like to share how to install OpenStack on your local VirtualBox using DevStack. Here are the steps as below. Hopefully you follow these steps to set up your own first OpenStack environment.

• 5 Step 5: Trouble Shooting

Step 1: Pre-requisition

Set up linux box

I tried ubuntu-12.04.4-server-amd64.iso, which you can get from here: http://releases.ubuntu.com/12.04/

Lunch Virtual Box, and add new drive for iso.

Set up Ubuntu machine

Login and run the commands below.

 sudo locale-gen en_US
 sudo apt-get -y update
 sudo apt-get -y upgrade
 sudo apt-get -y install git
 sudo apt-get install -q -y python-all-dev curl dos2unix aptitude python-setuptoolS
 sudo apt-get install -q -y python-pip
 sudo apt-get install apache2
 sudo apt-get install apache2.2-common
 sudo apt-get install -q -y build-essential swig
 sudo ufw disable
 sudo apt-get install libmysqlclient-dev

Make sure you set up proxy if you are in office.

Step 2: Preparation

2.1 add user: stack

sudo adduser stack

You have to put password and confirm again

sudo apt-get install sudo -y || yum install -y sudo

echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

PS: can #sudo vi /etc/sudoers

Insert the line "stack ALL=(ALL) NOPASSWD: ALL”

sudo su stack
sudo mkdir -p /opt/workspace
sudo chown -R stack:stack /opt/workspace
pushd /opt/workspace

sudo apt-get install git -y || yum install -y git
sudo git clone https://github.com/openstack-dev/devstack.git
sudo apt-get install git -y || yum install -y git

PS: if you can’t download, disconnect LAN and use direct wireless and refresh network connection

Step 3: Set up DevStack

cd opt/workspace/devstack
       sudo cp samples/local.conf local.conf
       sudo vi local.conf

 localrc
       FLOATING_RANGE=192.168.1.224/27
       FIXED_RANGE=10.11.12.0/24
       FIXED_NETWORK_SIZE=256
       FLAT_INTERFACE=eth0
       ADMIN_PASSWORD=secret
       MYSQL_PASSWORD=secret
       RABBIT_PASSWORD=secret
       SERVICE_PASSWORD=secret

PS: if you set up proxy, it’s better connect to company LAN and refresh connection

sudo chown -R stack:stack /opt/workspace/devstack

sudo su stack ./stack.sh

Run around 20-30 minutes, depending on download speed.

After installation, shut down machine

sudo shutdown –P now

Step 4: Modified Network Configuration

Set up three network adapters

1. Change adapter 1 from NAT to Bridge
2. Add local host adapter
3. Add NAT

Set up Network Adapter, ref: http://docs.openstack.org/training-guides/content/lab000-virtualbox-basics.html

VMnet0 is for bridge

VMnet1 is for host only

VMnet2 is for NAT

Boot the VM

Log in and cd to devstack directory

sudo su stack
cd /opt/workspace/devstack
sudo su stack ./unstack.sh
sudo su stack ./stack.sh

Regarding ending message; try username: admin and password: e.g: admin and secret

Step 5: Trouble Shooting

PS: refresh network connection

General networking restart

sudo /etc/init.d/networking restart

NIC restart (on the console - ie: not remotely):

ifdown eth0
ifup eth0

PS: if there is an error from nova login

HTTPConnectionPool(host='192.168.1.12', port=8774): Max retries exceeded with url: /v2/70a04e8259b04717bf1bdd4faaedbc0c/extensions (Caused by <class 'socket.error'>: [Errno 111] Connection refused)

Since it’s all in one DevStack, the worst case is run stack.sh again

sudo su stack ./stack.sh

after reboot your Ubuntu, you need to run script

sudo su stack ./rejoin-stack.sh 

to start services

Hopeful you have fun for this sharing.
