Initial steps

Before we can install OpenStack, some work must be done to prepare the system for a successful installation.

Updating the system

Before packages can be downloaded, run the following apt-get command to update package lists on all hosts:

# apt-get update

Permissions

OpenStack services can be installed either as root or as a user with sudo permissions. The latter may require that the user be added to the sudoers file on each host. For tips on configuring sudoers, visit https://help.ubuntu.com/community/RootSudo.

Note

For this installation, all commands should be run as root, unless specified otherwise.

Configuring the OpenStack repository

Installation of OpenStack on Ubuntu 14.04 LTS uses packages from the Ubuntu Cloud Archive repository when installing versions of OpenStack that are newer than what the operating system shipped with. To enable the Cloud Archive repository, download and install the Ubuntu-cloud-keyring package on all hosts:

# apt-get install ubuntu-cloud-keyring
