Apache Libcloud is a standard Python library that abstracts away differences among multiple cloud provider APIs. At the moment it can be used to manage four different kinds of cloud services: servers, storage, loadbalancers and DNS. Here are the steps to install Libcloud on a machine running CentOS 6:
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm yum install python-pip pip-python install apache-libcloud
The first step installs the Extra Packages for Enterprise Linux (EPEL) repository. This repository contains the pip command, which is a package manager for Python. If you want to deploy nodes on the different clouds, you need an additional package:
yum install gcc python-devel pip-python install paramiko
The paramiko package adds SSH capabilities to Python and allows the Libcloud library to SSH into your nodes and perform initial configuration.
