New combined CLI tool installation
[name@server ~]$ sudo apt-get install python-dev python-pip
[name@server ~]$ pip install python-openstackclient
see [http://docs.openstack.org/cli-reference/common/cli_install_openstack_command_line_clients.html]
To install on a machine (ACENET specifically without admin privileges) use:
[name@server ~]$ pip install --user python-openstackclient
which installs to ~/.local/lib/pythonX.Y/site-packages/ so by adding export PYTHONPATH=${HOME}/.local/lib/python2.7/site-packages/:${PYTHONPATH} to your .bashrc file if you are using Python major version X=2, and minor version Y=7.
It seems that the new openstack command line client, works more interactively? If I run the command
[name@server ~]$ openstack
starts up an interactive prompt and get get a list of available commands by typing help</cod> at the openstack prompt.
