Verification

The purpose of the verification step is to confirm that the cloud is in working order and to discover some of the defaults used by MicroStack. Verification will consist of the following actions:

perform various OpenStack queries

create an instance

connect to the instance over SSH

access the cloud dashboard

Query OpenStack

To list the default image

sudo microstack.openstack image list

Outcome:

+--------------------------------------+--------+--------+
| ID                                   | Name   | Status |
+--------------------------------------+--------+--------+
| e6aebf13-e081-4cab-8323-61123a4f6033 | cirros | active |
+--------------------------------------+--------+--------+

.

To get the default list of flavors

sudo microstack.openstack flavor list

Outcome:

+----+-----------+-------+------+-----------+-------+-----------+
| ID | Name      |   RAM | Disk | Ephemeral | VCPUs | Is Public |
+----+-----------+-------+------+-----------+-------+-----------+

Create an instance

MicroStack comes with a convenient instance creation command called microstack launch. It uses the following defaults for its instances:

keypair ‘microstack’

flavor ‘m1.tiny’

floating IP address on subnet ‘10.20.20.0/24’

To create an instance named ‘test’ based on the ‘cirros’ image

sudo mkdir -p /home/root/snap/microstack/common

sudo microstack launch cirros -n test

Outcome:

Creating local "microstack" ssh key at /home/root/snap/microstack/common/.ssh/id_microstack
Launching server ...
Allocating floating ip ...
Server test launched! (status is BUILD)

Access it with `ssh -i /home/root/snap/microstack/common/.ssh/id_microstack cirros@10.20.20.26`

Pre-requisites for using OpenStack

There are a few basic pre-requisites you need to fulfill, before setting up OpenStack on your system.

• Ubuntu OS

• A minimum of 4 GB RAM

• Multi-core enabled processor

• At least 10GB of free hard disk space

• A good internet connection

There are some additional software requirements also, which you need to fulfill.

• Git

• A web browser

Steps to Install Openstack on Ubuntu with Devstack

Installing OpenStack on Ubuntu is a rather complex process. But it is made easy by Devstack. The steps to install it, are quite easy even if you’re not much proficient with the command line, simply follow the steps and get it up and running.

Step 1: Preparing the system

Update the system:

sudo apt-get update && sudo apt-get upgrade -y

The command will ask for root privileges. Enter your user password and wait for your system to upgrade. After the upgrade is done, reboot.

Step 2: Creating stack user with Sudo privileges

Create a new user named stack for our system to setup OpenStack, as it should be installed on a non-root user with sudo enabled.

Open a fresh terminal, and run the useradd command:

sudo useradd -s /bin/bash -d /opt/stack -m stack

Enable stack user to have root privileges and run without a password:

echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack

The Output will look like this:

Adding User – “stack”

Once you have created the stack user, log in to it using the following command:

sudo su - stack

It will log in you to bash, as stack user.

Logging-in as User “stack”

Step 3: Downloading Devstack

Assuming git is installed on your system. Enter the following command to download/clone devstack from its repository to your system:

git clone https://opendev.org/openstack/devstack

Devstack repo contains a script stack.sh , which will be used to setup OpenStack. It also contains templates for configuration files.

Step 4: Creating configuration (.conf) file for Devstack

Setup the configuration files for it.

Navigate to the devstack folder, by running:

cd devstack

Afterwards, create a local.conf file, by running:

vim local.conf

and paste the following content –

[[local|localr]]   ADMIN_PASSWORD=StrongAdminSecret DATABASE_PASSWORD=$ADMIN_PASSWOCinder RABBIT_PASSWORD=$ADMIN_PASSWORD SERVICE_PASSWORD=$ADMIN_PASSWORD

Paste using the mouse by right-clicking and clicking Paste and enter :x to save & exit.

Note:
1. StrongAdminSecret is the password we used here, you can change it with your choice.
2. A sample configuration file for local.conf can be found in the Samples directory under the Devstack repository.

Step 5: Installing Openstack with Devstack

Run OpenStack installation using the following command:

./stack.sh

The script will install the following features –

• Horizon – OpenStack Dashboard

• Keystone – Identity Service

• Nova – Compute Service

• Glance – Image Service

• Neutron – Network Service

• Placement – Placement API

• Cinder – Block Storage Service

The setup will take around 10 to 20 minutes, based on your system performance and internet speed, as many git trees and packages are installed during the process.

Upon completion, your terminal will look like the image below.

Devstack Installed

Now, we can see that it is saying that Horizon (Openstack Dashboard) is available at the given URL, it will vary from system to system.

Step 6: Accessing OpenStack using a web browser

Browse this URL –

1	https://server-ip/dashboard

Or try

1	https://localhost/dashboard

It will open up the OpenStack login page, as shown below.

Openstack Login

Now, enter the credentials ie Admin/StrongAdminSecret

After logging in, your dashboard will look similar to this.

[openstack] Preinstalled-Openstack-VirtualBox-x64

 .

Preinstalled-Openstack-VirtualBox-x64

A Pre-installed Openstack CentOS 7 x64 image that can be directly imported onto VirtualBox. You can literally setup and test Openstack in under 10 minutes. There's no need to install Openstack using this VirtualBox (.vbox/.vdi) image.

Preface:

I have spent hours setting up every solution out there to test Openstack. None of them are actually easy considering the heavy PC requirements and the time taken to build the Openstack modules from scratch. This solution would absolutely remove the hassle of installing Openstack, before being able to test it out. This solution does not require you to install any other application other than VirtualBox on your PC/Laptop. Openstack uses a lot of CPU and Memory resources. Please ensure that all your other applications have been saved/closed before running this VM.

This method uses a pre-installed packstack Openstack binary. These binaries are installed on an IP address: 10.0.2.15, which is the default NAT IP that VirtualBox assigns a new machine using a NAT Adapter.

Minimum Requirements:

• x64 compatible PC/Laptop that supports x64 compatible Virtual hosts
• Latest VirtualBox application installed on your PC/Laptop
• Atleast 4 GB Hard Drive space
• 6 GB RAM
• 4 CPU cores (Quad Core)

Note: You can always increase the RAM, Hard Disk space and the CPU Cores based on your Openstack requirements. Higher configuration is required for running Virtual instances within Openstack smoothly.

Download the Centos-openstack compressed VirtualBox Image from: https://drive.google.com/open?id=0Bw59oF2-DxdEU2hrb3AwN2RicFk

Alternative: https://archive.org/download/centos-openstack

Installation Instructions:

1. Download and Extract the zip file onto "VirtualBox VMs" folder located under your Users/ folder in your PC.

2. Open VirtualBox application and import the contents of the zip file (Using Machine -> Add option). You should see the entry Centos-openstack in your VM after the import.

3. Quit all other applications running in your laptop/PC. Only then run this VM. The preset settings require you have a quad core x64 PC along with 6GB ram at least. Trust me, this isn't enough for Openstack still.

4. Ensure that the Centos-openstack -> Settings page does not have any invalid settings. Also ensure that the following configurations are properly in-place:

VM Settings:

a. Under Settings -> USB (turn off USB controller) if it shows up as invalid settings. Adjust your RAM to be at or below 80 % of your actual PC's Memory capacity.

b. Under Centos-openstack -> Settings -> Network, Check if the NAT Adapter is enabled. Ensure that your PC/Laptop running the VirtualBox application has internet connectivity.

c.Under Centos-openstack -> Settings -> Network -> Adapter 1 (NAT), Click the "Port Forwarding" button and check if the following Port Forwarding options are in-place, else configure them.

d. Check the Settings page of your Centos-openstack VM. It should more-or-less be having the following settings:

Now start the VM. Let it load. Use the following PC credentials:

username: openstack

password: openstack

In the console, run the following command: sudo dhclient enp0s3

[openstack@openstack ~]$ sudo dhclient enp0s3

Provide the "openstack" password.

Now, check if you have obtained the 10.0.2.15 IP for enp0s3 interface using the command: ifconfig

[openstack@openstack ~]$ ifconfig

This may not work properly if you get any other IP than 10.0.2.15. From your PC/Laptop's browser you should access the following website: http://localhost:8888

Note: Openstack components may take 5 - 10 minutes to load once the VM has booted up and IP has been configured. Please wait a few minutes or refresh the browser's page if you do not see the Openstack horizon web interface as soon as you put them in your browser for the first time.

Openstack's horizon web dashboard should appear with login credentials screen appearing first.

The credentials are:

username: admin

password: openstack

This should take to your Openstack console, where you can experiment with Openstack.

Debug:

If your Openstack web dashboard does not come up properly, check if your local port 8888 is not being blocked by your local firewall.

If the NAT IP obtained from dhclient was something other than 10.0.2.15, you can try this command and check if your Horizon web dashboard opens up from your PC after issuing this command:

[openstack@openstack ~]$ sudo ifconfig enp0s3 10.0.2.15 netmask 255.255.255.0

[openstack@openstack ~]$ sudo route add default gw 10.0.2.2 dev enp0s3

[openstack@openstack ~]$ sudo su

<Enter "openstack" password>

[openstack@openstack ~]# nameserver 8.8.8.8 >> /etc/resolv.conf

Try to open an ssh terminal from the host PC/Laptop's Putty or ssh client.

Use the command: ssh openstack@localhost -p 2222

If you cannot access the VM's ssh console, then the NAT Port Forwarding is not working properly.

Cheers trying out Openstack, the hassle-free way!

Let me know if you have improvements.
