# **stack.sh** is an opinionated openstack developer installation.
|
||
|
||
# This script installs and configures *nova*, *glance*, *dashboard* and *keystone*
|
||
|
||
# This script allows you to specify configuration options of what git
|
||
# repositories to use, enabled services, network configuration and various
|
||
# passwords. If you are crafty you can run the script on multiple nodes using
|
||
# shared settings for common resources (mysql, rabbitmq) and build a multi-node
|
||
# developer install.
|
||
|
||
# To keep this script simple we assume you are running on an **Ubuntu 11.04
|
||
# Natty** machine. It should work in a VM or physical server. Additionally we
|
||
# put the list of *apt* and *pip* dependencies and other configuration files in
|
||
# this repo. So start by grabbing this script and the dependencies.
|
||
|
||
# Learn more and get the most recent version at http://devstack.org

# Sanity Check

# Settings
|

# ========

# want to override a setting you can either::
|
||
#
|
||
# export MYSQL_PASSWORD=anothersecret
|
||
# ./stack.sh
|
||
#
|
||
# You can also pass options on a single line ``MYSQL_PASSWORD=simple ./stack.sh``
|
||
#
|
||
# Additionally, you can put any local variables into a ``localrc`` file, like::
|
||
#
|
||
# MYSQL_PASSWORD=anothersecret
|
||
# MYSQL_USER=hellaroot
|
||
#
|
||
# We try to have sensible defaults, so you should be able to run ``./stack.sh``
|
||
# in most cases.
|
||
#
|
||
# We our settings from ``stackrc``. This file is distributed with devstack and
|
||
# contains locations for what repositories to use. If you want to use other
|
||
# repositories and branches, you can add your own settings with another file
|
||
# called ``localrc``
|
||
#
|
||
# If ``localrc`` exists, then ``stackrc`` will load those settings. This is
|
||
# useful for changing a branch or repostiory to test other versions. Also you
|
||
# can store your other settings like **MYSQL_PASSWORD** or **ADMIN_PASSWORD** instead
|
