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 # ============ # Warn users who aren't on natty, but allow them to override check and attempt # installation with ``FORCE=yes ./stack`` if ! egrep -q 'natty|oneiric' /etc/lsb-release; then echo "WARNING: this script has only been tested on natty and oneiric" if [[ "$FORCE" != "yes" ]]; then echo "If you wish to run this script anyway run with FORCE=yes" exit 1 fi fi # Keep track of the current devstack directory.
