# vargrant box add centos/7

Setup Environment

1. Create working directory

2. Create testing Vagrantfile

$ mkdir ~/OpenStackMeetUp$ cd ~/OpenStackMeetUP

OpenStack

- Open Source Cloud Computing Software - Software to control your cloud- Open source software for creating private and public clouds- One of the fastest growing open source community in the world

https://www.openstack.org/

RDO (RPM Distribution of OpenStack)

“... community-supported distribution of

OpenStack that runs on Red Hat Enterprise Linux

(RHEL) and its derivatives”

RDO (RPM Distribution of OpenStack)

“... community of users of cloud computing platform on Red Hat-based operating systems to get help and compare notes

on running OpenStack.”

OpenStack Components in RDO (Newton)

- Keystone: authentication, authorization and service discovery mechanisms - Glance: services for discovering, registering, and retrieving virtual machine

images.- Cinder: implement services and libraries to provide on demand, self-service

access to Block Storage resources.- Swift: distributed object storage system designed to scale from a single

machine to thousands of servers.- Nova: provides a cloud computing fabric controller, supporting a wide

variety of virtualization technologies, including KVM, Xen, LXC, VMware, and more.

OpenStack Components in RDO (Newton)

- Neutron: virtual network service for Openstack.- Heat: service to orchestrate multiple composite cloud applications using

templates, through both an OpenStack-native ReST API and a CloudFormation-compatible Query API.

- Ceilometer: project aims to become the infrastructure to collect measurements within OpenStack

- Gnocchi: project name of a TDBaaS (Time Series Database as a Service) project started under the Ceilometer program umbrella.

- Horizon: Django-based project aimed at providing a complete OpenStack Dashboard

OpenStack Components in RDO (Newton)

- Ironic: integrated OpenStack project which aims to provision bare metal machines instead of virtual machines.

- Trove: Database as a Service for OpenStack.- Sahara: aims to provide users with simple means to provision a Hadoop

cluster.- Tempest: set of integration tests to be run against a live OpenStack cluster.- Manila: shared filesystem management project for OpenStack.- Designate: OpenStack inspired DNSaaS.

Installation Method

RDO:

- Packstack- For PoC Environments- Using Puppet modules to deploy OpenStack

- TripleO (Next workshop? Please voted)- For Production Environments- Provision bare-metal machines then deploy production cloud environments- Undercloud → → Overclound

Packstack

“... is a utility that uses Puppet modules to deploy various

parts of OpenStack on multiple pre-installed servers over SSH

automatically. “

Packstack

Packstack currently only CentOS, Red Hat Enterprise Linux (RHEL) and compatible derivatives of both are supported.

Workshop: Prepare VirtualBox

- Get VagrantFile from “https://github.com/thamrongtawal/Openstack-Meetup-3-Vagrant”

- Vagrant up- Vagrant ssh

Packstack Requirements

- CentOS 7 (X86_64)- Repositories

- Base- Extras

- Hardware- 6+ GB RAM- 1 NIC- Virtualization enabled

- Network- Prefer Static IP

Workshop: Install Packstack

- Install Repo & Update OS

- Configure services

- Restart OS

# yum install -y centos-release-openstack-newton# yum update -y

# systemctl disable NetworkManager# systemctl disable firewalld# systemctl enable network

# reboot

Workshop: Install Packstack
