Install the prerequisite software and the Python package for each OpenStack client.

Most Linux distributions include packaged versions of the command-line clients that you can install directly, see . If you need to install the command-line packages source packages, the following table lists the software that you need to have to run the command-line clients, and provides installation instructions as needed.

Prerequisite software

Prerequisite	Description
Python 2.6 or later	Interpreter for the Python programming language.
setuptools package	Installed by default on Mac OS X. Many Linux distributions provide packages to make setuptools easy to install. Search your package manager for setuptools to find an installation package. If you cannot find one, download the setuptools package directly from https://pypi.python.org/pypi/setuptools. The recommended way to install setuptools on Microsoft Windows is to follow the documentation provided on the setuptools website. Another option is to use the unofficial binary installer maintained by Christoph Gohlke (http://www.lfd.uci.edu/~gohlke/pythonlibs/#setuptools).
pip package	To install the clients on a Linux, Mac OS X, or Microsoft Windows system, use pip. It is easy to use, ensures that you get the latest version of the clients from the Python Package Index, and lets you update or remove the packages later on. Since the installation process compiles source files, this requires the related Python development package for your operating system and distribution. Install pip through the package manager for your system: # easy_install pip Ensure that the C:\Python27\Scripts directory is defined in the PATH environment variable, and use the easy_install command from the setuptools package: C:\>easy_install pipAnother option is to use the unofficial binary installer provided by Christoph Gohlke (http://www.lfd.uci.edu/~gohlke/pythonlibs/#pip). # apt-get install python-dev python-pip Note that extra dependencies may be required, per operating system, depending on the package being installed, such as is the case with Tempest. A packaged version enables you to use yum to install the package: # yum install python-devel python-pip There are also packaged versions of the clients available in RDO that enable yum to install the clients as described in . A packaged version available in the Open Build Service enables you to use or zypper to install the package. First, add the Open Build Service repository: # zypper addrepo -f obs://Cloud:OpenStack:Kilo/SLE_12 Kilo Then install pip and use it to manage client installation: # zypper install python-devel python-pip There are also packaged versions of the clients available that enable zypper to install the clients as described in . You can install pip and use it to manage client installation: # zypper install python-devel python-pip There are also packaged versions of the clients available that enable zypper to install the clients as described in

When following the instructions in this section, replace PROJECT with the lowercase name of the client to install, such as nova. Repeat for each client. The following values are valid: ceilometer - Telemetry API cinder - Block Storage API and extensions glance - Image service API heat - Orchestration API neutron - Networking API nova - Compute API and extensions sahara - Database Processing API swift - Object Storage API trove - Database service API openstack - Common OpenStack client supporting multiple services The following CLIs are deprecated in favor of openstack, the Common OpenStack client supporting multiple services: keystone - Identity service API and extensions The following example shows the command for installing the nova client with pip. # pip install python-novaclient

Use pip to install the OpenStack clients on a Linux, Mac OS X, or Microsoft Windows system. It is easy to use and ensures that you get the latest version of the client from the Python Package Index. Also, pip enables you to update or remove a package. Install each client separately by using the following command: For Mac OS X or Linux: # pip install python-PROJECTclient For Microsoft Windows: C:\>pip install python-PROJECTclient

RDO, openSUSE and SUSE Linux Enterprise have client packages that can be installed without pip. On Red Hat Enterprise Linux, CentOS, or Fedora, use yum to install the clients from the packaged versions available in RDO: # yum install python-PROJECTclient For openSUSE, use zypper to install the clients from the distribution packages Service: # zypper install python-PROJECT For SUSE Linux Enterprise Server, use zypper to install the clients from the distribution packages in the Open Build Service. First, add the Open Build Service repository: # zypper addrepo -f obs://Cloud:OpenStack:Kilo/SLE_12 Kilo Then you can install the packages: # zypper install python-PROJECT

To upgrade a client, add the --upgrade option to the pip install command: # pip install --upgrade python-PROJECTclient To remove the a client, run the pip uninstall command: # pip uninstall python-PROJECTclient

Before you can run client commands, you must create and source the PROJECT-openrc.sh file to set environment variables. See .
