Install OpenStack Juno on CentOS 7 / RHEL 7

openstack
OpenStack is a free and open source cloud computing platform developed as a joint project of Rackspace Hosting and NASA. Users primarily deploy it as an Infrastructure as a Service (IaaS) solution. OpenStack cloud consists of many well know technologies like: Linux KVM, LVM, iSCSI, MariaDB (MySQL), RabbitMQ or Python Django.

OpenStack architecture overview:

  1. Horizon: web browser user interface (dashboard) based on Python Django for creating and managing instances (virtual machines)
  2. Keystone: authentication and authorization framework
  3. Neutron: network connectivity as a service
  4. Cinder: persistent block storage for instances based on LVM
  5. Nova: instances management system based on Linux KVM
  6. Glance: registry for instance images
  7. Swift: file storage for cloud
  8. Ceilometer: metering engine for collecting billable data and analysis.
  9. Heat: orchestration service for template-based instance deployment

In this tutorial we will install OpenStack Juno release from RDO repository on two nodes (controller node & compute node) based on CentOS 7 / RHEL 7.

Environment used:
public network (Floating IP network): 192.168.2.0/24
internal network: no IP space, physical connection only (eth1)
public controller IP: 192.168.2.4 (eth0)
public compute IP: 192.168.2.5 (eth0)
