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 classmate.This vm‘s system is also Ubuntu14.04.To my surprise, the same operation steps, this America vm installed successfully.Here is 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
$sudo su stack
7.under the stack,you create a configuration file named ‘localrc‘,there is the simplest configuration below,the official documentation is here:
[email protected]:/usr/local/devstack$ vim localrc
ADMIN_PASSWORD=secrete
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
SERVICE_TOKEN=$ADMIN_PASSWORD
#https协议打头是指通过http协议+TLS协议来克隆源码，
#解决碰到fatal: unable to connect to git.openstack.org的问题
GIT_BASE=${GIT_BASE:-https://git.openstack.org}
DEBUG=True
VERBOSE=True
DEST=/opt/stack
LOGFILE=$DEST/logs/stack.sh.log
SCREEN_LOGDIR=$DEST/logs/screen
SYSLOG=False
LOG_COLOR=False
LOGDAYS=7
8.start to install(notice that under the stack)
[email protected]:/usr/local/devstack$ ./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.

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.
