Installation and Configuration

HP Helion OpenStack Community Edition

https://docs.hpcloud.com/helion/community/install-overview/

2 installation methods:

• Virtual installation for testing and proof-of-concept

use

• Multi-node, baremetal installation for small-scale

production

A Cloud On Your Laptop? Why Not Three?...

“Overcloud”

“Undercloud”

“Seed”

OpenStack on OpenStack (TripleO)

There are many fragmented ways of deploying OpenStack. This is an open

source method

TripleO reuses OpenStack services and APIs to deploy OpenStack on

hardware (Nova and Ironic)

Heat provides deployment orchestration for hardware nodes, and captures

hardware configurations for repeatable deployments

TripleO can be implemented/merged with existing deployment methods.

The TripleO Installation Process

1) Deploy the Seed VM

The Seed VM contains the minimum services required of OpenStack to be

able to provision physical hardware to deploy the Undercloud

2) Deploy the Undercloud

The Undercloud server is a single-node OpenStack installation used to

deploy, test, manage, and update the Overcloud servers by Cloud

Operators

3) Deploy the Overcloud

The Overcloud is the functional cloud available to end users for

running guest virtual machines and workloads

Includes:

Virtual Installation

1 Undercloud

1 Overcloud controller

2 Swift nodes (in current release)

1 Overcloud compute node

1 Tenant VM

Installer system requirements (per the documentation):

• At least 48 GB of RAM

• At least 200 GB of available disk space

Virtual Install Architecture

Seed VM – 4GB RAM

Undercloud – 4GB RAM

Overcloud Nova Compute

4GB RAM

Overcloud Controller

4GB RAM

Note: 2 more Nodes in v1.3

“Demo” VM Instance

512MB RAM

2 levels of virtualization

Hardware Requirements (unofficial)

At least 16GB RAM

Fast drive (to accommodate swapping and virtualization load)

Documentation recommends 200GB available, but realistically uses around 80GB for install

Virtualization Enabled in BIOS (must have this)

Step 1: Setup Base Hardware

Install Ubuntu 13.10 or 14.04 LTS**

• Minimal, clean install recommended

Install required packages

• qemu

• openvswitch

• libvirt

• python-libvirt

• openssh-server

$ sudo apt-get install -y libvirt-bin openvswitch-switch python-libvirt qemu-system-x86 qemu-kvm openssh-server

Reboot

Step 2: Generate Public/Private Key Pair

Login as root:

$ sudo su –

Generate a public SSH key (no passphrase – use <ENTER> at

prompts)

# ssh-keygen -t rsa

Step 3: Download the Installation File

Register and download the virtual install package from

https://helion.hpwsportal.com – the file is named

Helion_Openstack_Community.tar.gz (5.3GB)

Tip: Verify the checksum to confirm

package integrity

Releases to date:

Preview – Released May 2014

V1.2 – Released June 2014

V1.3 – Released July 2014 (Support

Available)

Step 4: Unpack the Installation File

Log in as root

$ sudo su -

Unpack the file

$ tar zxvf ~path/Helion_Openstack_Community.tar.gz

This results in creation of a tripleo/ directory in the root’s home

directory

At this point, the preparation process is complete

Step 5: Start the Seed VM

NOTE: All STEPS MUST BE REPEATED FROM THIS POINT FORWARD EACH TIME THE PHYSICAL MACHINE IS

REBOOTED

Use the following command to start the seed VM

# HP_VM_MODE=y bash -x ~root/tripleo/tripleo-incubator/scripts/hp_ced_start_seed.sh

This process can take 10 minutes or more

• The first time this is run, it will check to ensure all of the required packages are

installed. If you are prompted, accept all package installations

• You will see a lot of logging messages while the script runs

If the Seed VM start is successful, a message is displayed

Wed Aug 27 11:25:10 UTC 2014 --- completed setup seed

Step 6: Verify Seed VM Startup

Confirm the se ed VM is running by using the virsh list command

# virsh list

root@mymachine:~# virsh list

Id Name State

---

0 seed running

Note: The Seed VM continues with self-initialization after the

script has competed. Good idea to wait a few minutes…..

Possible Seed VM Start Errors

Run the script a second time if needed

• error: unsupported configuration: Domain requires KVM, but it is not

available -- Check that virtualization is enabled in the BIOS

• error: Failed to start domain seed

error: unsupported configuration: SATA is not supported with this

QEMU binary -- Change ‘sata’ to ‘ide’ in the seed machine template in

~/tripleo/tripleo-incubator/templates/vm.xml

Optional Aid: Seed VM Memory Management

Note: The Seed VM is configured to use 4096MB of RAM. It is

possible to reduce the VM memory allocation to conserve

resources in extreme cases, although this will increase the

load for swap files on your disk

• Open ~/tripleo/tripleo-

incubator/scripts/hp_ced_start_seed.sh

• Find MEMORY=${NODE_MEM:-4096} and change 4096

to the desired amount (ex. 2048)

Step 7: Connect to the Seed VM

Confirm logged in as root on the Ubuntu host (if needed)

$ sudo su -

Connect via SSH to the Seed VM (hLinux)

$ ssh 192.0.2.1

• Type yes to allow the SSH connection to proceed when

prompted for host authentication

• Ensure language environment is set (using the commands

referenced during SSH connection setup), or via other

methods*

*Setting Language Environments

To avoid an unsupported locale error when issuing Neutron

commands from within the Seed VM, run the following

root@hLinux:~# export LANG=C

Step 8: Start Undercloud and Overcloud install

On the Seed VM, launch the install script

root@hLinux:~# bash -x ~root/tripleo/tripleo-incubator/scripts/hp_ced_installer.sh

Learn patience 

v1.3 release includes informational comments in the script

- “this could take up to 15 or more minutes”

- “waiting for undercloud to stabililze”

- “waiting for the overcloud stack to be ready”

- “this could take up to 30 or more minutes”

- “this is the final step – expect to wait eight or more minutes”

Success = “HP - completed -Wed Aug 27 16:20:02 UTC 2014”

Step 9: Verify the Install – Demo Guest VM

On the Seed, setup the environment and list the running instance

root@hLinux:~# source ~root/tripleo/tripleo-overcloud-passwords

root@hLinux:~# TE_DATAFILE=tripleo/testenv.json

root@hLinux:~# source ~root/tripleo/tripleo-incubator/overcloudrc-user

root@hLinux:~# nova list

The nova list command shows the running demo VM

Record the IP address of the demo instance, and verify with PING and SSH*

Step 10: Verify the Install – Overcloud

On the Seed, access the overcloud and list the running instances

root@hLinux:~# source ~root/tripleo/tripleo-undercloud-passwords

root@hLinux:~# TE_DATAFILE=tripleo/testenv.json

root@hLinux:~# source ~root/tripleo/tripleo-incubator/undercloudrc

root@hLinux:~# nova list

The nova list command shows the running overcloud instances

NOTE: 2 instances using older releases, 4 instances using v1.3 (7/22)

Step 11: Connecting to the Horizon Console

Obtain the passwords for the demo and admin users

root@hLinux:~# grep OVERCLOUD_DEMO_PASSWORD ~root/tripleo/tripleo-overcloud-passwords

root@hLinux:~# grep OVERCLOUD_ADMIN_PASSWORD ~root/tripleo/tripleo-overcloud-passwords

Connect to the Horizon console

http://192.0.8.2 for v1.3 (7/22)

http://<IP of overcloud controller> for v1.2

Log in as demo or admin using the corresponding passwords

Horizon Interface

* Referenced in Step: 8 – Verify the Install – Demo Guest VM

Demo VM Instance IP Address for SSH (v1.3)

See PDF attachment for instructions for accessing Instances via SSH

Remote Connection to the Horizon Console

Establish a tunnel on the local system (Linux)

$ ssh -L 9999:<IP of overcloud controller>:80 <hostname or IP of remote system>

On Windows, you can use PuTTY

Expand SSH + Tunnels properties

Enter 9999 as Source Port

Enter the Horizon host IP as Destination

Click <Add>

Connect to the remote Horizon console from the local system

http://localhost:9999

Finished - Enjoy Your New HP Helion Cloud(s)!!!

Maintenance and Cleanup Notes

For best performance, cleanup VMs and environment

• Delete the KVM VMs and their storage volumes using virsh

commands

• Delete /tmp/seed_options and /var/lib/libvirt/images/

• Uninstall any packages that you no longer require (apt)

• Delete the downloaded .tar package to recover space
