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

Update hosts file

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

update Interface

In my environment I have a DHCP server and a DNS server on the lab network and all the install on the lab network are done by pxe boot and a preseed file that auto configure my first network interface. My interface file looks like the one below. If you do not have a DHCP or DNS server you can do this manually.

# The primary network interface
auto eno1
iface eno1 inet static
       address 10.192.16.38
       netmask 255.255.252.0
       network 10.192.16.0
       broadcast 10.192.19.255
       gateway 10.192.16.1
       # dns-* options are implemented by the resolvconf package, if installed
       dns-nameservers 10.192.16.2 10.192.16.4
       dns-search dfw.ppnet
# The secondery network interface
auto eno2
iface eno2 inet static
       address 10.192.0.75
       network 10.192.0.0
       netmask 255.255.255.0

Compute node

Update hosts file

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

Update interface

# The primary network interface
 auto eno1
 iface eno1 inet static
       address 10.192.16.67
       netmask 255.255.252.0
       network 10.192.16.0
       broadcast 10.192.19.255
       gateway 10.192.16.1
       # dns-* options are implemented by the resolvconf package, if installed
       dns-nameservers 10.192.16.2 10.192.16.4
       dns-search dfw.ppnet
# The secondery network interface
auto eno2
iface eno2 inet static
       address 10.192.0.73
       network 10.192.0.0
       netmask 255.255.255.0

Testing Network

From you controller node ping the compute node

ping compute.dfw.ppnet
PING compute.dfw.ppnet (10.192.16.67) 56(84) bytes of data.
64 bytes from compute.dfw.ppnet (10.192.16.67): icmp_seq=1 ttl=64 time=0.286 ms

From your compute node ping the controller node

ping controller.dfw.ppnet
PING controller.dfw.ppnet (10.192.16.38) 56(84) bytes of data.
64 bytes from controller.dfw.ppnet (10.192.16.38): icmp_seq=1 ttl=64 time=0.206 ms

Now that our environment is ready lest move to the OpenStack installation.

Controller node installation

Login to your controller node as root and copy the script below into you root directory.

Create a repertory called controller and download and upload all the files into the directory.

file to upload

File:Controllertar.zip

Note: I am using password=password1 for all passwords in this tutorial. You can use a different password.

Location where you need to use a password:

MYSQL passwword
RabbitMQ password
User keystone password
User glance password
User nova password
User neutron password

You need to change what is in red in the script to match your environment.

Before running the script

There are some settings that needs to change first in some of the files we upload to the /root/controller/ repertory. Navigate to the controller repertory

cd controller

lets start with the file keystone.conf.if you changed the default password in the controller-node.sh you need to change it also on line 643.

643 connection = mysql+pymysql://keystone:password1@controller/keystone

The next file is the glance-api.conf. if the password was changed too in the controller-node.sh use the same password on line 1735 and line 3190

1735 connection = mysql+pymysql://glance:password1@controller/glance
---
3190 password = password1

Next file: glance-registry.conf on line 1025

1025 connection = mysql+pymysql://glance:password1@controller/glance

OpenStack dashboard (Horizon) login

After the script complete with no error, login to the horizon by typing your_controller_IP_Address/horizon into your browser. In my case i am using the 10.192.0.0/24 network address to access horizon since the computer I am using for this tutorial is on that network.

http://10.192.0.75/horizon/

You have 2 options here to login: login with the user admin or with the user demo with the password you set. In my case i am going to use user=admin and password=password1

Compute node installation

Login to your compute node as root and copy the script below into you root directory. For the compute node, I am using also password=password1. You can change this with your own password.

vi install-compute-node.sh

#!/bin/bash
if [ "$(id -u)" != "0" ]; then
  echo "This script must be run as root" 1>&2
  exit 1
fi
PASSWORD=password1
CONFIG_DIR=/root/compute
echo "Enable the Openstack repository"
sleep 3
       apt -y install software-properties-common
       add-apt-repository -y cloud-archive:newton
       apt update && apt -y dist-upgrade
echo "Install the Openstack client"
sleep 3
       apt -y install python-openstackclient
echo "Install libvirt-bin"
sleep 3
       sudo apt-get -y install libvirt-bin
##Install nova compute
echo "Start to Install Nova"
sleep 3
       apt-get install -y nova-compute
       mv /etc/nova/nova.conf /etc/nova/nova.conf~
       cp $CONFIG_DIR/nova.conf /etc/nova
       chown nova:nova /etc/nova/nova.conf
       service nova-compute restart
sleep 3
##neutron installation
echo "Install the network components"
sleep 3
apt install -y neutron-linuxbridge-agent
mv /etc/neutron/neutron.conf /etc/neutron/neutron.conf~
cp $CONFIG_DIR/neutron.conf /etc/neutron/neutron.conf
chown root:neutron /etc/neutron/neutron.conf
mv /etc/neutron/plugins/ml2/linuxbridge_agent.ini /etc/neutron/plugins/ml2/linuxbridge_agent.ini~
cp $CONFIG_DIR/linuxbridge_agent.ini /etc/neutron/plugins/ml2/linuxbridge_agent.ini
service nova-compute restart
sleep 3
service neutron-linuxbridge-agent restart
sleep 3
