Welcome to the First Release OpenStack Install Scripts

This project aims to covert the steps in the OpenStack Install guide into useful/simple scripts. The goal is not to provide a complete automation solution. But the idea is to have simple building blocks which can help developers and enthusiasts experiment with OpenStack in a much simpler fashion.

Platform supported - Ubuntu

OpenStack version - Juno

OpenStack services installed

The following OpenStack services are installed as part these scripts:

  1. Keystone (Identity)
  2. Glance (Image)
  3. Nova (Compute)
  4. Neutron (Networking)
  5. Horizon (Dashboard)
  6. Ceilometer (Telemetry)

Download

You can use wget command to download the package. The links to ZIP and TAR.GZ files are given bewlo

Important Notes

  1. The installation installs only Open vSwitch packages by default. Installing Linux bridge can be done using a utility script provided in util directory.
  2. The Nova configuration includes a setting to use AllHostsFilter as the default filter for scheduler. If you want the default filters of Nova, remove this entry and restart Nova services on the controller.
  3. Many scripts detect the OpenStack Node Type automatically using util/detect-nodetype.sh script.

How to use the scripts step by step

  1. Update lib/config-parameters.sh script
    • Change the hostname to be used for controller. This name will be used in all configuration files.
    • You will need to use this name to update the /etc/hosts file for correct lookups. The util/update-etc-hosts.sh script can be used for this purpose.
    • Change passwords as necessary
  2. Install common packages
    • Execute sudo bash install.sh common
    • It is a good idea to reboot the system since kernel packages may have been updated.
  3. Install OpenStack packages depending upon the type of the node
    • If the node is of type controller, execute sudo bash install.sh controller
    • If the node is of type compute, execute sudo bash install.sh compute
    • If the node is of type networknode, execute sudo bash install.sh networknode
    • If the node is of type allinone, execute sudo bash install.sh allinone
    • Note - during the installation of MariaDB, you will be required to enter DB password manually
  4. Configure OpenStack packages using sudo bash configure.sh. The node type is detected automatically
    • Note - during the configuration of MariaDB, you will be required to confirm few DB clean up operations manually

Updating IP Address

The install scripts use a name for the controller (defined in config-parameters.sh script). This name needs to be updated in the /etc/hosts file. Also to view the VNC console of an instance, it is convenient to use IP address in the Nova configuration file. All these changes can be done using util/update-ip.sh script.

Usage: sudo bash util/update-ip.sh <controller-host-name> <controller-ip>.
The second parameter is used only for compute nodes.

Removing OpenStack packages

You can remove all the OpenStack packages using sudo bash remove.sh. The node type is detected automatically and the corresponding packagesa are removed.

Restarting OpenStack services

Restarting OpenStack services is needed at times - especially when config file entries are changed. You can execute sudo bash restart.sh to do this. The node type is detected automatically.

Updating /etc/hosts file

Since all configuration uses the name of the controller host, it is important to update /etc/hosts file on all the node to map an IP address to the controller host name. You can use the util/update-etc-hosts.sh script for this purpose.
