You must have Python 2.7 and Python pip installed on your CentOS 7 host before you can install OpenStack CLI. Python is available, by default, on a CentOS 7 host.

For some reason, if Python and pip are not already installed, you must install Python and pip first, and then install OpenStack CLI.

Use the following commands to install Python and pip.

yum install -y epel-release
yum install -y gcc openssl-devel python-pip python-wheel python-virtualenv python-virtualenvwrapper

Install OpenStack CLI

Once Python and pip are installed, you are ready to set up a virtual environment and install OpenStack CLI on the virtual environment.

Follow the steps given below to install OpenStack CLI.

  1. Load the virtualenvwrapper setup script into your current shell session.
    # location of
    source /usr/bin/
    # directory to store virtual environments
    export WORKON_HOME=$HOME/.virtenvs
  2. Create a new virtual environment.
    mkvirtualenv os_cli

    The context switches to the newly created virtual environment.</li>

  3. Upgrade pip.
    pip install pip --upgrade
  4. Run following command to set up Openstack CLI.
    pip install --upgrade --requirement --constraint
  5. </ol>

    OpenStack CLI is successfully installed, and ready to be used on the CentOS 7 host.
