NOTE: this is still work in progress!

VM setup

Get CentOS 6.6 VM setup. Nothing fancy - Basic server, one interface.

After OS is installed, do yum upgrade 

# yum upgrade

# yum install git

# git clone https://github.com/openstack-dev/devstack.git -b stable/icehouse /opt/devstack

# cd /opt/devstack/
# tools/create-stack-user.sh 
# chown -R stack:stack /opt/devstack

Switch off SELinux and iptables: 

# vi /etc/sysconfig/selinux 
# setenforce 0
# getenforce 
# service iptables stop

Upgrade all packages to the latest (just to be up to date): 

# yum upgrade
# sudo -i -u stack

Get and set devstack

Create /opt/devstack/local.conf file 

[stack@devstack devstack] cd /opt/devstack
[stack@devstack devstack] vi local.conf

Below configuration file is based on this example 

[[local|localrc]]

Let’s stack it now 

[stack@devstack devstack] ./stack.sh

You will see this error: 

[stack@devstack devstack]$ ./stack.sh 
Loaded plugins: fastestmirror
Using mysql database backend
Traceback (most recent call last):
  File "/opt/devstack/tools/outfilter.py", line 24, in <module>
    import argparse
ImportError: No module named argparse

To fix it, install python-setuptools and argparse as was hinted in this post 

[stack@devstack devstack] sudo yum install python-setuptools -y
[stack@devstack devstack] sudo easy_install argparse

It will eventually fail again with the below: 

2014-11-25 11:22:20.797 | ERROR: openstack Unknown command ['project', 'create', 'admin']

Upgrade setuptools and try again. Hint came from here 

[stack@devstack devstack] sudo pip install --upgrade requests setuptools
[stack@devstack devstack] ./unstack.sh
[stack@devstack devstack] ./stack.sh

Bongo! 

Horizon is now available at http://10.0.2.15/
Keystone is serving at http://10.0.2.15:5000/v2.0/
Examples on using novaclient command line is in exercise.sh
The default users are: admin and demo
The password: devstack
This is your host ip: 10.0.2.15

Now run some tests: 

[stack@devstack devstack] ./exercise.sh 

<...skipped loads of output...>

SKIP marconi
SKIP sahara
PASS aggregates
PASS bundle
PASS client-args
PASS horizon
PASS sec_groups
PASS swift
PASS trove
FAILED boot_from_volume
FAILED client-env
FAILED euca
FAILED floating_ips
FAILED neutron-adv-test
FAILED volumes

CLI environment variables.

If you try to engage CLI at this stage, this is what you get: 

[stack@devstack devstack]$ glance image-list
You must provide a username via either --os-username or env[OS_USERNAME]

We need to setup environment variables to be able to use CLI.

If you scroll up after running the test script, you will see something like this: 

++ export OS_TENANT_NAME=demo
++ OS_TENANT_NAME=demo
++ export OS_USERNAME=demo
++ OS_USERNAME=demo
++ export OS_PASSWORD=devstack
++ OS_PASSWORD=devstack
++ export OS_NO_CACHE=1
++ OS_NO_CACHE=1
++ HOST_IP=10.0.2.15
++ SERVICE_HOST=10.0.2.15
++ SERVICE_PROTOCOL=http
++ KEYSTONE_AUTH_PROTOCOL=http
++ GLANCE_HOST=10.0.2.15
++ export OS_IDENTITY_API_VERSION=2.0
++ OS_IDENTITY_API_VERSION=2.0
++ export OS_AUTH_URL=http://10.0.2.15:5000/v2.0
++ OS_AUTH_URL=http://10.0.2.15:5000/v2.0

Based on OpenStack docs we will need the below ones defined: 

export OS_USERNAME=admin
export OS_PASSWORD=devstack
export OS_TENANT_NAME=demo
export OS_AUTH_URL=http://10.0.2.15:5000/v2.0

Open ~stack/.bashrc and add those line to the bottom of the file; save & exit; re-read .bashrc and off you go: 

[stack@devstack devstack]$ vi ~/.bashrc 
[stack@devstack devstack]$ . ~/.bashrc 
[stack@devstack devstack]$ glance image-list
