h1. Introduction

This document refers to the installation manual of the main components of

OpenStack. The version of each component used can be found in the respective

sections of the components.

This document was produced by the Center for Scientific Computing, UNESP, with

funding from Intel and UNESP.

OpenStack OpenStack is a global collaboration of developers and cloud computing

technologists producing the ubiquitous open source cloud computing platform for 

public and private clouds. The project aims to deliver solutions for all types

of clouds by being simple to implement, massively scalable, and feature rich.

The technology consists of a series of interrelated projects delivering various

components for a cloud infrastructure solution.

The OpenStack project is divided into sub projects that have a specific role in

the big picture.

The main components are: Cloud Compute (Nova) Cloud Storage (Swift), Image 

registration and delivery (Glance), Identity (Keystone) and Dashboard

(Horizon).

Each component is independent of each other and can be installed on separate

machines, or all in one. In the environment of UNESP, OpenStack was installed in

seven machines, described in section "Environment used."

This document is modified version of OpenStack Install and Deploy Manual [1] 

with minor adjustments and changes to resolve problems encountered during 

installation and adjustment to the environment in which it was installed.

h1. OpenStack Core Components

OpenStack is a collection of open source technology that provides massively

scalable open source cloud computing software. Currently OpenStack develops two

related projects: OpenStack Compute, which offers computing power through

virtual machine and network management, and OpenStack Object Storage which is

software for redundant, scalable object storage capacity. Closely related to the

OpenStack Compute project is the Image Service project, named Glance. OpenStack

can be used by corporations, service providers, VARS, SMBs, researchers, and

global data centers looking to deploy large-scale cloud deployments for private

or public clouds.

The main components are: Cloud Compute (Nova) Cloud Storage (Swift), Image

registration and delivery (Glance), Identity (Keystone) and Dashboard

(Horizon).

They are presented here in an order for educational purposes only to a 

straightforward procedure for installation. But following a brief description of

each component.

h2. Keystone

Keystone is an OpenStack project that provides Identity, Token, Catalog and 

Policy services for use specifically by projects in the OpenStack family. It

implements OpenStack’s Identity API.

h2. Cloud Compute (Nova)

Nova is the project name for OpenStack Compute, a cloud computing fabric

controller, the main part of an IaaS system. Individuals and organizations can

use Nova to host and manage their own cloud computing systems. Nova originated

as a project out of NASA Ames Research Laboratory.

h2. Object Storage (Swift)

OpenStack Object Storage (Swift) is a system to store objects in a massively

scalable large capacity system with built-in redundancy and failover. Object

Storage has a variety of applications, such as backing up or archiving data,

serving graphics or videos (streaming data to a user's browser), storing

secondary or tertiary static data, developing new applications with data

storage integration, storing data when predicting storage capacity is difficult,

and creating the elasticity and flexibility of cloud-based storage for your web

applications.

h2. Image Service (Glance)

OpenStack Image Service (Glance) is a lookup and retrieval system for virtual

machine images. It can be configured in three ways: using OpenStack Object Store

to store images; using Amazon's Simple Storage Solution (S3) storage directly;

or using S3 storage with Object Store as the intermediate for S3 access.

h1. Environment Proposed

This document aims to guide you in setting up a test environment or development.

The original documentation suggests many machines. To install OpenStack here,

you will need only one or two machines.

You can install all services on one machine only (all-in-one). Or you can

install OpenStack controller (all services except the nova-compute) on machine A

and a compute cloud controller on machine B.

For a production environment it is advisable to separate the elements to ensure

a high availability and redundancy.

Settings used in this document:

 - Cloud Controller:

 - Cloud Computer Node:

All machines are installed with Ubuntu Server 12.04 LTS.

h1. Initial configuration

Before starting the installation and configuration of each component must first

to make some adjustments.

h2. Network Configuration

For both conserving network resources and ensuring that network administrators

understand the needs for networks and public IP addresses for accessing the APIs

and VMs as necessary, this section offers recommendations and required minimum

sizes. Throughput of at least 1000 Mbps is suggested.

For OpenStack Compute, networking is configured on multi-node installations

between the physical machines on a single subnet. For networking between virtual

machine instances, three network options are available: flat, DHCP, and VLAN.

Two NICs (Network Interface Cards) are recommended on the server running

nova-network.

Management Network (RFC1918 IP Range, not publicly routable): This network is

utilized for all inter-server communications within the cloud infrastructure.

Recommended size: 255 IPs (CIDR /24)

Public Network (Publicly routable IP range): This network is utilized for

providing Public IP accessibility to the API endpoints within the cloud

infrastructure. Minimum size: 8 IPs (CIDR /29)

VM Network (RFC1918 IP Range, not publicly routable): This network is utilized

for providing primary IP addresses to the cloud instances. Recommended size:

1024 IPs (CIDR /22)

Floating IP network (Publicly routable IP Range): This network is utilized for

providing Public IP accessibility to selected cloud instances. Minimum size:

16 IPs (CIDR /28)

In this installation we will use eth0 to public interface and eth1 for

management interface.

h2. Installing Network Time Protocol (NTP)

To keep all the services in sync, you need to install NTP, and if you do a

multi-node configuration you will configure one server to be the reference

server.

# apt-get install -y ntp

Set up the NTP server on your controller node so that it receives data by

modifying the ntp.conf file and restarting the service. As root:

# sed -i 's/server ntp.ubuntu.com/server ntp.ubuntu.com\nserver 127.127.1.0\

nfudge 127.127.1.0 stratum 10/g' /etc/ntp.conf

# service ntp restart

Set up the NTP client on your compute node so that the time between controller

node and compute node is synchronized. Do the following as a cron job on compute

node.

# ntpdate 'controllernode ip'

# hwclock -w

h2. Storage

Many cloud computing use cases require persistent remote storage. Storage

solutions are often divided into three categories: object storage, block

storage, and file storage.

Here we will use a "object storage" and a "block storage".

h3. Object storage (swift)

With object storage, files are exposed through an HTTP interface, typically with

a REST API. All client data access is done at the user level: the operating

system is unaware of the presence of the remote storage system. In OpenStack,

the Object Storage service provides this type of functionality. Users access and

modify files by making HTTP requests. Because the data accesss interface provided

by an object storage system is at a low level of abstraction, people often build

on top of object storage to build file-based applications that provide a higher

level of abstraction. For example, the OpenStack Image service can be configured

to use the Object Storage service as a backend. Another use for object storage

solutions is as a content delivery network (CDN) for hosting static web content

(e.g., images, and media files), since object storage already provides an HTTP

interface.

h3. Block storage (SAN)

With block storage, files are exposed through a low-level computer bus interface

such as SCSI or ATA, that is accessible over the network. Block storage is

synonymous with SAN (storage area network). Clients access data through the

operating system at the device level: users access the data by mounting the

remote device in a similar manner to how they would mount a local, physical disk

(e.g., using the "mount" command in Linux). In OpenStack, the nova-volume

service that forms part of the Compute service provides this type of

functionality, and uses iSCSI to expose remote data as a SCSI disk that is

attached to the network.

Because the data is exposed as a physical device, the end-user is responsible

for creating partitions and formatting the exposed disk device. In addition,

in OpenStack Compute a device can only be attached to one server at a time, so

block storage cannot be used for to share data across virtual machine instances

concurrently.

h1. Installation Assumptions

OpenStack Compute has a large number of configuration options. To simplify this

installation guide, we make a number of assumptions about the target

installation:

 * You have a collection of compute nodes, each installed with Ubuntu Server

12.04

 * You have designated one of the nodes as the Cloud Controller, which will run

all of the services (RabbitMQ, MySQL, Identity, Image, nova-api, nova-network,

nova-scheduler, nova-volume) except for nova-compute.

 * The disk partitions on your cloud controller are being managed by the Logical

Volume Manager (LVM)

 * Your Cloud Controller has an LVM volume group named "nova-volumes" to provide

persistent storage to guest VMs. Either create this during the installation or

leave some free space to create it prior to installing nova services.

 * Ensure that the server can resolve its own hostname, otherwise you may have

problems if you are using RabbitMQ as the messaging backend (RabbitMQ is the default

messaging back-end on Ubuntu, on Fedora the default backend is Qpid).

 * 192.168.69.1 is the primary IP for our controller host on eth0 and

192.168.69.2 is the primary IP for our computer node on eth0.

 * FlatDHCP with a single network interface.

 * KVM as the hypervisor.

 * Ensure the operating system is up-to-date by running apt-get update and

apt-get upgrade prior to the installation.

 * Ensure that all hosts are with ntp and correct time.

This installation process walks through installing a cloud controller node and a

compute node using a set of packages that are known to work with each other.

The cloud controller node contains all the nova- services including the API

server and the database server. The compute node needs to run only the

nova-compute service. You only need one nova-network service running in a

multi-node install.

h1. Keystone

The OpenStack Identity service manages users, tenants (accounts or projects) and

offers a common identity system for all the OpenStack components.

The Identity services has two primary functions:

 1. User management: keep track of users and what they are permitted to do

 2. Service catalog: Provide a catalog of what services are available and where

their API endpoints are located.

h2. User management

The three main concepts of Identity user management are:

* Users

* Tenants

* Roles

A user represents a human user, and has associated information such as username,

password and email.

A tenant can be thought of as a project, group, or organization. Whenever you

make requests to OpenStack services, you must specify a tenant. For example, if

you query the Compute service for a list of running instances, you will receive

a list of all of the running instances in the tenant you specified in your

query.

A role captures what operations a user is permitted to perform in a given tenant.

h3. Service management

The two main concepts of Identity service management are:

* Services

* Endpoints

The Identity service also maintains a user that corresponds to each service

(e.g., a user named nova, for the Compute service) and a special service tenant,

which is called service.

h3. Installing Keystone

O Keystone é um projeto que provê serviços de "Identidade", "Token", "Catalog" and "Policy" para os componentes do OpenStack. O pacote *_keystone_* foi instalado no servidor _educloud01_.

Este software é feito em python, e por sua vez instala a dependencia *_keystone-python_*, uma biblioteca em python para uso do próprio keystone.

Os arquivos de configuração do keystone ficam em /etc/keystone e hoje ele está utilizando como um backend para armazenar os usuários uma base sqlite3, mas ele também permite que seja utilizado uma base LDAP.

Além do daemon (servidor) foi instalado o cliente (também feito em python) *_python-keystoneclient_*.

h2. Instalando e configurando o keystone

<pre>

# apt-get install keystone

</pre>

Delete the keystone.db file created in the /var/lib/keystone directory.

<pre>

# rm /var/lib/keystone/keystone.db

</pre>

Install mysql:

<pre>

# apt-get install python-mysqldb mysql-server

</pre>

Use sed to edit /etc/mysql/my.cnf to change bind-address from localhost

(127.0.0.1) to any (0.0.0.0) and restart the mysql service, as root:

<pre>

# sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mysql/my.cnf

# service mysql restart

</pre>

To configure the MySQL database, create the keystone database.

<pre>

# mysql -u root -p

mysql> CREATE DATABASE keystone;

mysql> GRANT ALL ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'keystonepass';

mysql> FLUSH PRIVILEGES;

mysql> quit;

</pre>

Edit _*keystone.conf*_ to use mysql:

<pre>

[sql]

connection = mysql://keystone:keystonepass@192.168.69.1/keystone

</pre>

Change in _*keystone.conf*_ the ADMIN_TOKEN:

<pre>

admin_token = 012345SECRET99TOKEN012345

</pre>

Restarte o keystone e inicialize o banco:

<pre>

# service keystone restart

# keystone-manage db_sync

</pre>

h2. Configuring Services to work with Keystone

Crie o arquivo _*/root/openstackrc*_, com o seguinte conteudo:

<pre>

export SERVICE_ENDPOINT=http://192.168.69.1:35357/v2.0/

export SERVICE_TOKEN=012345SECRET99TOKEN012345

</pre>

Estas variaveis de ambiente sao uteis para evitar ficar passando as opcoes --token e --endpoint para os utilitarios de linha de comando. 

Carrege o arquivo:

<pre>

# source /root/openstackrc

</pre>

Crie os *tenants* _openstackDemo_ e _service_:

<pre>

# keystone tenant-create --name openstackDemo --description "Default Tenant"  --enabled true

# keystone tenant-create --name service --description "Service Tenant"  --enabled true

</pre>

Crie o *user* _admin_, substitua o tenant_id pelo tentant_id do openstackDemo, criado no item anterior:

<pre>

# keystone user-create --tenant_id 9c401c9d2b9d41bcabda6919d4aec63a --name admin --pass adminpass --enabled true

</pre>

Crie os *roles* _admin_ e _user_:

<pre>

# keystone role-create --name admin

# keystone role-create --name user

</pre>

Adicione o *user* _admin_ ao *role* _admin_, fazendo as devidas substituicoes:

<pre>

# keystone user-role-add --user [admin_user_id] --tenant_id [openstackDemo_tenant_id] --role [admin_role]

</pre>

Crie um usuario para cada servico, e substitua o tenant_id pelo id do tenant *service*:

<pre>

# keystone user-create --tenant_id 92920816c7704a8a95c916d34dc7a05c --name glance --pass glancepass --enabled true

# keystone user-create --tenant_id 92920816c7704a8a95c916d34dc7a05c --name nova --pass novapass --enabled true

# keystone user-create --tenant_id 92920816c7704a8a95c916d34dc7a05c --name swift --pass swiftpass --enabled true

</pre>

Adicione os users acima ao *role* _admin_, fazendo as devidas substituicoes:

<pre>

# keystone user-role-add --user [glance_user_id] --tenant_id [service_tenant_id] --role [admin_role]

# keystone user-role-add --user [nova_user_id] --tenant_id [service_tenant_id] --role [admin_role]

# keystone user-role-add --user [swift_user_id] --tenant_id [service_tenant_id] --role [admin_role]

</pre>

h2. Definindo os servicos:

Ate agora, apenas criamos: tenants, users e roles. O Keystone tambem gerencia os servicos e seus endpoins. Desta forma os componentes do openstack consulta o keystone onde determinado servico encontra-se.

Crie os servicos:

<pre>

# keystone service-create --name keystone --type identity --description "Keystone Identity Service" 

# keystone service-create --name nova --type compute --description "Nova Compute Service"

# keystone service-create --name volume --type volume --description "Nova Volume Service"

# keystone service-create --name glance --type image --description "Glance Image Service"

# keystone service-create --name swift --type object-store --description "Object Storage Service"

</pre>

Crie os endpoints para os respectivos servicos:

<pre>

# keystone endpoint-create --region RegionOne --service_id [keystone_service_id] --publicurl http://192.168.69.1:5000/v2.0 --internalurl http://192.168.69.1:5000/v2.0 --adminurl http://192.168.69.1:35357/v2.0

# keystone endpoint-create --region RegionOne --service_id [compute_service_id] --publicurl 'http://192.168.69.1:8774/v2/%(tenant_id)s' --internalurl 'http://192.168.69.1:8774/v2/%(tenant_id)s' --adminurl 'http://192.168.69.1:8774/v2/%(tenant_id)s'

# keystone endpoint-create --region RegionOne --service_id [volume_service_id] --publicurl 'http://192.168.69.1:8776/v1/%(tenant_id)s' --internalurl 'http://192.168.69.1:8776/v1/%(tenant_id)s' --adminurl 'http://192.168.69.1:8776/v1/%(tenant_id)s'

# keystone endpoint-create --region RegionOne --service_id [glance_service_id] --publicurl http://192.168.69.1:9292/v1 --internalurl http://192.168.69.1:9292/v1 --adminurl http://192.168.69.1:9292/v1

# keystone endpoint-create --region RegionOne --service_id [swift_service_id] --publicurl 'http://192.168.69.1:8888/v1/AUTH_%(tenant_id)s' --adminurl 'http://192.168.69.1:8888/' --internalurl 'http://192.168.69.1:8888/v1/AUTH_%(tenant_id)s'

</pre>

h2. Verificando a instalacao:

<pre>

# sudo apt-get install curl openssl

</pre>

Faca uma requisicao REST para a API do keystone usando o curl:

<pre>

# curl -d '{"auth": {"tenantName": "openstackDemo", "passwordCredentials": {"username": "admin", "password": "adminpass"}}}' -H "Content-type: application/json" http://192.168.69.1:35357/v2.0/tokens  | python -mjson.tool

</pre>

O retorno deve conter todos os servicos, endpoins e um token que expira em 24 horas:

<pre>

h1. Installing OpenStack Object Storage - Swift

[Descrever o Swift aqui]

Como neste ambiente de desenvolvimento temos apenas um no para storage e este sera o mesmo no que estara instalado o swift-proxy, todos os passos abaixo, sao executados na mesma maquina: _educloud01_.

Em um ambiente de producao aconselha-se ter pelo menos 05 object storage nodes e 01 object proxy node.

h2. Instalando e configurando o swift

<pre>

# apt-get install swift python-xattr python-memcache rsync memcached python-netifaces

</pre>

Infelizmente no momento da escrita deste manual o pacote do swift nao automatiza algumas tarefas, como por exemplo, a criacao dos arquivos de configuracao. Teremos que fazer isso manualmente:

<pre>

# mkdir /etc/swift

</pre>

Crie o arquivo de configuracao _/etc/swift/swift.conf_:

<pre>

[swift-hash]

# random unique string that can never change (DO NOT LOSE)

swift_hash_path_suffix = fLIbertYgibbitZ

</pre>

h2. Instalando e configurando os "object nodes"

<pre>

# apt-get install swift-account swift-container swift-object xfsprogs

</pre>

Cada "Object node" pode ter muitos dispositivos ligados a eles. 'E necessario que seja utilizado o sistema de arquivos xfs. 

<pre>

# fdisk /dev/sdb (set up a single partition)

# mkfs.xfs -i size=1024 /dev/sdb1

</pre>

Este dispositivo deve estar montando em /srv/node/

<pre>

echo "/dev/sdb1 /srv/node/sdb1 xfs noatime,nodiratime,nobarrier,logbufs=8 0 0" >> /etc/fstab

mkdir -p /srv/node/sdb1

mount /srv/node/sdb1

chown -R swift:swift /srv/node

</pre>

h2. Configure o _rsyncd.conf_

<pre>

uid = swift

gid = swift

log file = /var/log/rsyncd.log

pid file = /var/run/rsyncd.pid

address = 192.168.69.1

[account]

max connections = 2

path = /srv/node/

read only = false

lock file = /var/lock/account.lock

[container]

max connections = 2

path = /srv/node/

read only = false

lock file = /var/lock/container.lock

[object]

max connections = 2

path = /srv/node/

read only = false

lock file = /var/lock/object.lock

</pre>

Edite o _/etc/default/rsync_:

<pre>

RSYNC_ENABLE = true

</pre>

Restarte o rsync:

<pre>

service rsync restart

</pre>

Crie o _/etc/swift/account-server.conf_:

<pre>

[DEFAULT]

bind_ip = 192.168.69.1

workers = 2

[pipeline:main]

pipeline = account-server

[app:account-server]

use = egg:swift#account

[account-replicator]

[account-auditor]

[account-reaper]

</pre>

Crie o _/etc/swift/container-server.conf_:

<pre>

[DEFAULT]

bind_ip = 192.168.69.1

workers = 2

[pipeline:main]

pipeline = container-server

[app:container-server]

use = egg:swift#container

[container-replicator]

[container-updater]

[container-auditor]

</pre>

Crie o _/etc/swift/object-server.conf_:

<pre>

[DEFAULT]

bind_ip = 192.168.69.1

workers = 2

[pipeline:main]

pipeline = object-server

[app:object-server]

use = egg:swift#object

[object-replicator]

[object-updater]

[object-auditor]

</pre>

h2. Instale e configure o swift-proxy

<pre>

# apt-get install swift-proxy memcached

</pre>

Crie o certificado SSL auto assinado:

<pre>

cd /etc/swift

openssl req -new -x509 -nodes -out cert.crt -keyout cert.key

</pre>

Modifique o memcached para ouvir na interface da sua rede interna. Edite a seguinte linha no /etc/memcached.conf, mudando

<pre>

-l 127.0.0.1

to

-l 192.168.69.1

</pre>

Restart o memcached:

<pre>

service memcached restart

</pre>

Crie o arquivo _/etc/swift/proxy-server.conf_:

<pre>

[DEFAULT]

bind_port = 8888

user = swift

[pipeline:main]

pipeline = catch_errors healthcheck cache authtoken keystone proxy-server

[app:proxy-server]

use = egg:swift#proxy

account_autocreate = true

[filter:keystone]

paste.filter_factory = keystone.middleware.swift_auth:filter_factory

operator_roles = admin, swiftoperator

[filter:authtoken]

paste.filter_factory = keystone.middleware.auth_token:filter_factory

# Delaying the auth decision is required to support token-less

# usage for anonymous referrers ('.r:*').

delay_auth_decision = 10

service_port = 5000

service_host = 192.168.69.1

auth_port = 35357

auth_host = 192.168.69.1

auth_token = 012345SECRET99TOKEN012345

admin_token = 012345SECRET99TOKEN012345

auth_protocol = http

[filter:cache]

use = egg:swift#memcache

set log_name = cache

[filter:catch_errors]

use = egg:swift#catch_errors

[filter:healthcheck]

use = egg:swift#healthcheck

</pre>

Create the account, container and object rings. The builder command is basically creating a builder file with a few parameters. The parameter with the value of 18 represents 2 ^ 18th, the value that the partition will be sized to. Set this "partition power" value based on the total amount of storage you expect your entire ring to use. The value of 1 represents the number of replicas of each object, with the last value being the number of hours to restrict moving a partition more than once.

<pre>

cd /etc/swift

swift-ring-builder account.builder create 18 1 1

swift-ring-builder container.builder create 18 1 1

swift-ring-builder object.builder create 18 1 1

</pre>

For every storage device on each node add entries to each ring:

<pre>

swift-ring-builder account.builder add z<ZONE>-<STORAGE_LOCAL_NET_IP>:6002/<DEVICE> 100

swift-ring-builder container.builder add z<ZONE>-<STORAGE_LOCAL_NET_IP_1>:6001/<DEVICE> 100

swift-ring-builder object.builder add z<ZONE>-<STORAGE_LOCAL_NET_IP_1>:6000/<DEVICE> 100

</pre>

Como no nosso caso, apenas temos uma zona, em um storage node e com um device (sdb1), o comando acima ficaria:

<pre>

swift-ring-builder account.builder add z1-192.168.69.1:6002/sdb1 100

swift-ring-builder container.builder add z1-192.168.69.1:6001/sdb1 100

swift-ring-builder object.builder add z1-192.168.69.1:6000/sdb1 100

</pre>

Verify the ring contents for each ring:

<pre>

swift-ring-builder account.builder

swift-ring-builder container.builder

swift-ring-builder object.builder

</pre>

Rebalance the rings:

<pre>

swift-ring-builder account.builder rebalance

swift-ring-builder container.builder rebalance

swift-ring-builder object.builder rebalance

</pre>

Altere as permissoes dos arquivos de configuracao:

<pre>

# chown -R swift:swift /etc/swift/

</pre>

Inicie o swift-proxy:

<pre>

swift-init proxy start

</pre>

Inicie todos os servicos:

<pre>

swift-init main start

swift-init rest start

</pre>

h2. Verificando a instalacao

O arquivo _/root/openstackrc_ vai receber novas variaveis de ambiente, ele deve ficar assim:

<pre>
