How to install Openstack Newton

For this tutorial, we will be installing Openstack Newton on Ubuntu 16.04 (Xenial). You can use the same tutorial also on Debian 8 (Jessie) but this will install Openstack Mitaka. This tutorial is to help people that wants to start to learn Openstack.

Prerequisites

To complete this tutorial, you'll need the following:

• 1 controller node

• 1 compute node

Hardware requirements

According to the Openstack Documentation, to run several CicrOS instances you will need:

• Controller Node: 1 processor, 4 GB memory, and 5 GB storage
• Compute Node: 1 processor, 2 GB memory, and 10 GB storage

This this tutorial I am using:

• Controller Node: 2 processors, 16 GB memory, 2x250GB disks in a Raid1 configuration and 2 NIC's (eno1 and eno2)
• Compute Node: 2 processors, 16 GB memory, 2x350GB disks in a Raid1 configuration and 2 NIC's (eno1 and eno2)

Your environment doesn't have to have 2 disks in Raid1 configuration, 1 disk will be okay.

Networking

I am using a Cisco switch to setup 2 VLAN's

• manegment VLAN
• Provider VLAN ( Internet)

If you don't have a Cisco switch, you can use two 4 port switches

Controller node

Make sure the node has Ubuntu 16.04 installed with all updates. If you do not have a DNS server in your environment manually update the hosts file

/etc/hosts

controller mgmt_IP_address controller.your_domain_name controller compute mgmt_IP_address computer.your_domain_name compute

example

10.192.16.38 controller.dfw.ppnet controller 10.192.16.67 compute.dfw.ppnet computer

In my case I have a DNS server in my environement so my /etc/hosts file looks like this:

127.0.0.1       localhost
10.192.16.38     controller.dfw.ppnet   controller

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
