'''Resumo:'''
 +
 
 +
O  ambiente  em  que  encontram-se  as  redes  de  computadores  está  em  frequente transformação,  evolução  e  consequentemente  a  massificação  dos  seus  recursos.
 +
Estes  sistemas  e  recursos  precisam  ser  dinâmicos,  gerenciáveis  e  elásticos  para poderem adequar-se às necessidades dos usuários. Diante deste cenário desenvolvese um ambiente de computação em nuvem no IFSC, aplicando o modelo infraestrutura
 +
como  serviço.  Que  possibilita  o  provisionamento  dos  recursos  computacionais (processamento,  armazenamento  e  rede de  computadores)  aos  usuários de forma simples, automatizada e remotamente controlada.  As  pesquisas e atividades foram
 +
em cima da plataforma aberta  OpenStack,  demonstrando-se então uma ferramenta completa e simples do ponto de vista do usuário.

'''Abstract:'''
 +
 
 +
The  current  environment  from  the  computer  networks  faces  frequent  changes, evolution  and  consequently  the  massification  of  its  resources.  These  systems  and resources need to be dynamic, manageable and elastic in order to adapt to the needs users.  In  this  scenario  has  been  developed  an  environment  of  cloud  computing  at IFSC,  applying  the  model  infrastructure  as  a  service.  It  lets  the  provisioning  of computers resources (compute, storage, networking) in a simple, automated, remotely controlled way to the users.  The research and activities were on  the open platform OpenStack,  demonstrating a complete and simple  tool from the point of view of the user.

Resumo:

O ambiente em que encontram-se as redes de computadores está em frequente transformação, evolução e consequentemente a massificação dos seus recursos. Estes sistemas e recursos precisam ser dinâmicos, gerenciáveis e elásticos para poderem adequar-se às necessidades dos usuários. Diante deste cenário desenvolvese um ambiente de computação em nuvem no IFSC, aplicando o modelo infraestrutura como serviço. Que possibilita o provisionamento dos recursos computacionais (processamento, armazenamento e rede de computadores) aos usuários de forma simples, automatizada e remotamente controlada. As pesquisas e atividades foram em cima da plataforma aberta OpenStack, demonstrando-se então uma ferramenta completa e simples do ponto de vista do usuário.

Abstract:

The current environment from the computer networks faces frequent changes, evolution and consequently the massification of its resources. These systems and resources need to be dynamic, manageable and elastic in order to adapt to the needs users. In this scenario has been developed an environment of cloud computing at IFSC, applying the model infrastructure as a service. It lets the provisioning of computers resources (compute, storage, networking) in a simple, automated, remotely controlled way to the users. The research and activities were on the open platform OpenStack, demonstrating a complete and simple tool from the point of view of the user.

Instalação

Controlador da nuvem (penny)

Configuração básica

Atualizando o sistema

apt-get update; apt-get upgrade; apt-get dist-upgrade</syntaxhighlight>

Configurando interfaces de rede - /etc/network/interfaces

auto lo iface lo inet loopback

  1. OpenStack - Rede de gerenciamento

auto p5p1 iface p5p1 inet static 

       address 192.168.88.251
       netmask 255.255.255.0
  1. OpenStack - Rede de configuração

auto p5p1:0 iface p5p1:0 inet static 

       address 192.168.89.251
       netmask 255.255.255.0
  1. OpenStack - IFSC

auto em1 iface em1 inet manual 

       up ifconfig $IFACE 0.0.0.0 up
       up ip link set $IFACE promisc on
       up ethtool -s em1 wol g
       down ip link set $IFACE promisc off
       down ifconfig $IFACE down

auto br-ex iface br-ex inet static 

      address 172.18.3.251
      netmask 255.255.192.0
      gateway 172.18.0.254
      dns-nameservers 8.8.8.8 8.8.4.4

</syntaxhighlight>

Instalando e configurando NTP server

sudo apt-get install -y ntp 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 </syntaxhighlight>

Instalando e configurando MySQL
Instalando pacotes.

Durante a instalação será pedido para inserir uma senha de root. sudo apt-get install -y python-mysqldb mysql-server</syntaxhighlight>

Mudando bind-address e aplicando a nova configuração

sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mysql/my.cnf service mysql restart </syntaxhighlight>

Criando banco de dados

mysql -u root -p <<EOF CREATE DATABASE nova; GRANT ALL PRIVILEGES ON nova.* TO 'novaUser'@'localhost' IDENTIFIED BY 'senha'; CREATE DATABASE cinder; GRANT ALL PRIVILEGES ON cinder.* TO 'cinderUser'@'localhost' IDENTIFIED BY 'senha'; CREATE DATABASE glance; GRANT ALL PRIVILEGES ON glance.* TO 'glanceUser'@'localhost' IDENTIFIED BY 'senha'; CREATE DATABASE keystone; GRANT ALL PRIVILEGES ON keystone.* TO 'keystoneUser'@'localhost' IDENTIFIED BY 'senha'; CREATE DATABASE quantum; GRANT ALL PRIVILEGES ON quantum.* TO 'quantumUser'@'localhost' IDENTIFIED BY 'senha'; FLUSH PRIVILEGES; EOF </syntaxhighlight>

Instalando servidor de fila de mensagem

sudo apt-get install rabbitmq-server rabbitmqctl change_password guest NovaSenha </syntaxhighlight>

OpenStack Identity Service (codenome Keystone)

Instalando Keystone

sudo apt-get install -y keystone python-keystone python-keystoneclient sudo rm /var/lib/keystone/keystone.db </syntaxhighlight>

Configurando Keystone

edit keystone files

Aplicando a nova configuração

service keystone restart keystone-manage db_sync </syntaxhighlight>

Criando tenants, usuários, roles, serviços e endpoints

  1. !/bin/bash
  1. Modify these variables as needed

ADMIN_PASSWORD=${ADMIN_PASSWORD:-senhaAdministrador} SERVICE_PASSWORD=${SERVICE_PASSWORD:-senhaServiço} export OS_SERVICE_TOKEN="C8gqDVqW99pAY7yXewUy" export OS_SERVICE_ENDPOINT="http://localhost:35357/v2.0" SERVICE_TENANT_NAME=${SERVICE_TENANT_NAME:-nomeDoServiço}

MYSQL_USER=keystone MYSQL_DATABASE=keystone MYSQL_HOST=localhost MYSQL_PASSWORD=password

KEYSTONE_REGION=IFSC-SJ-01 KEYSTONE_HOST_EXT=172.18.3.251 KEYSTONE_HOST_INT=192.168.88.251

  1. Shortcut function to get a newly generated ID

function get_field() { 

   while read data; do
       if [ "$1" -lt 0 ]; then
           field="(\$(NF$1))"
       else
           field="\$$(($1 + 1))"
       fi
       echo "$data" | awk -F'[ \t]*\\|[ \t]*' "{print $field}"
   done

}

  1. Tenants

ADMIN_TENANT=$(keystone tenant-create --name=admin | grep " id " | get_field 2) SERVICE_TENANT=$(keystone tenant-create --name=$SERVICE_TENANT_NAME | grep " id " | get_field 2)

Migrando Quantum para Neutron

Upgrades from Grizzly

Starting the neutron-server after upgrading code, but prior to migration will result in some database models being created without the proper migrations occurring. The following upgrade setups should be taken to ensure a properly upgraded database.

Ensure that the database is stamped for Grizzly prior to stopping service.quantum-db-manage --config-file /path/to/quantum.conf --config-file /path/to/plugin/conf.ini stamp grizzly Stop quantum-server and deploy the Neutron code Do not start the neutron-server at this time. Run Havana Migration neutron-db-manage --config-file /path/to/quantum.conf --config-file /path/to/plugin/conf.ini upgrade havana Start neutron-server </syntaxhighlight>
