Devstack single node Installation on VM

Last three days, I want to install devstack on my virtual machine on Vmware Workstation.The VM'system is Ubuntu14.04. However,i met too many problem to install it successfully.When i cannot see the hope, i had to borrow a America VM from my workmate.This vm's system is also Ubuntu14.04.To my surprise, the same operation steps, this America vm installed successfully.Here is a picture which shows eventual installation:

Now,let me show my installation steps(thanks to SongPeng who is one of my emc workmate)

official documentation is here

1.update your system

$sudo apt-get update

2.reboot:make it work

3.install your git

$sudo apt-get install git

4.download devstack source code

$cd /usr/local/

$sudo git clone https://git.openstack.org/openstack-dev/devstack

5.in order to avoid permisstion denied, you can use create-stack-user.sh to create a user named stack and a group also named stack

$sudo /usr/local/devstack/tools/create-stack-user.sh

$sudo chown -R stack:stack /usr/local/devstack/

6.access stack

$sudo su stack

7.under the stack,you create a configuration file named 'localrc',there is the simplest configuration below,the official documentation is here:

stack@ubuntu:/usr/local/devstack$ vim localrc

ADMIN_PASSWORD=secrete
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
SERVICE_TOKEN=$ADMIN_PASSWORD
#solve ‘fatal: unable to connect to git.openstack.org’
GIT_BASE=${GIT_BASE:-https://git.openstack.org}

DEBUG=True
VERBOSE=True
DEST=/opt/stack
LOGFILE=$DEST/logs/stack.sh.log
SCREEN_LOGDIR=$DEST/logs/screen

SYSLOG=False
LOG_COLOR=False
LOGDAYS=7

8.start to install(notice that under the stack)

stack@ubuntu:/usr/local/devstack$ ./stack.sh

Till now,above is installation steps.Below are problems which i met and solutions.

grep -ir 'error|fail|usage|not found' /opt/stack/logs/stack.sh.log
grep -ir 'error|fail|usage|not found' /opt/stack/logs/screen/

A useful tip: when you see "error", scroll the log up until you find the root one.

Download dependency failed

Symptom:

1.

2.

 Cause:Network is not stable

 Solution:manual download relative dependency by yourself and install it

$cd /tmp/
$wget  https://pypi.python.org/packages/source/B/Bable-1.3.tar.gz
#verify md5 consistancy
$md5sum Bable-1.3.tar.gz 
$sudo pip install --upgrade Bable-1.3.tar.gz

Module version does not exist!

Symptom

:./stack.sh:68+sudo a2enmod version
ERROR: Module version does not exist!

The code location is in lib/apache:68. See the comment

Ensure mod_version enabled for . This is built-in statically on anything recent, but precise (2.2) doesn't have it enabled

So, feel free to ignore this error.

openstack role list raises unrecognized arguments: --group（thanks to Accelazh）

The first reason is that the python-openstackclient version is too old (openstack --version), upgrade it

sudo pip install --upgrade python-openstackclient

You need to add python-openstackclient to LIBS_FROM_GIT in local.conf, to make sure devstack uses the newest version of python-openstackclient. Note that, devstack will use master branch of python-openstackclient instead of stable/kilo.

# Add python-openstackclient to your LIBS_FROM_GIT
LIBS_FROM_GIT=python-openstackclient

The next step, since keystone v2.0 doesn't even have the concept "group", you need to force here to use keystone V3 api.
