Ubuntu based OpenStack IceHouse Installation

[AmitKumarDas]

Start

• check memory of VM/box
• check capacity of VM/box
• use 64-bit version
• example assumes 3 node architecture
  • 1 controller, 1 network & 1 compute

Networking at controller

• configure 1st interface as management interface

  IP address: 10.0.0.11
  Network mask: 255.255.255.0 (or /24)
  Default gateway: 10.0.0.1

  set hostname of the node to controller
  edit /etc/hosts file to resolve controller, network & compute address

  remove the 127.0.0.1 line

Networking at network

• configure 1st interface as management interface
• configure 2nd interface as instance tunnels interface
• configure 3rd interface as the external interface
• external interface does not need an IP address configured
• replace INTERFACE_NAME with actual interface name e.g. eth2
  • edit /etc/network/interfaces

  # The external network interface
  auto INTERFACE_NAME
  iface INTERFACE_NAME inet manual
    up ip link set dev $IFACE up
    down ip link set dev $IFACE down

• restart network

  - service networking stop && service networking start

• name resolution @ /etc/hosts
  • remove 127.0.0.1 line entry

Networking at compute

• configure 1st interface as management interface
• configure 2nd interface as instance tunnels interface
• name resolution

Verify networking connectivity

  - verify internet connection
    - @ controller # ping -c 4 openstack.org
  - verify controller to network's management connection
    - @ controller # ping -c 4 network
  - verify controller to compute's management connection
    - @ controller # ping -c 4 compute

  - similarly do @ network
  - similarly do @ compute

Synchronize services across multiple machines

  - @ controller # apt-get install ntp

  - configure the other nodes to sync from controller node
    - install the ntp daemon as above
    - edit /etc/ntp.conf
      - change server directive to use controller node

Controller & mysql

  - apt-get install python-mysqldb mysql-server
    - remember the db root password

• edit /etc/mysql/my.cnf

  - [mysqld]
  bind-address = management IP of controller node

  - bind-address enables access to mysql from other nodes via management network

• verify /etc/mysql/my.cnf

  - default-storage-engine = innodb
  - collation-server = utf8_general_ci
  - init-connect = 'SET NAMES utf8'
  - character-set-server = utf8

• restart mysql

  - service mysql restart

• delete anonymous users that are created when db is first started

  - mysql_secure_installation
  - if above fails:
    - mysql_install_db
    - mysql_secure_installation

Other nodes & mysql

• install mysql python library

  - apt-get install python-mysqldb

OpenStack packages

• ubuntu cloud archive is a repo that allows to install newer releases of OpenStack
• on stable supported version of ubuntu

  - apt-get install python-software-properties
  - add-apt-repository cloud-archive:icehouse
  - apt-get update
  - apt-get dist-upgrade

  - reboot

Install message broker service

  - apt-get install rabbitmq-server

• default install creates guest for username & password
  • replace with a suitable password
  • mention the password in .conf files for all services

  - rabbitmqctl change_password guest <RABBIT_PASS>

Install identity service

  - apt-get install keystone

• update the MySQL database info at conf files
  • edit /etc/keystone/keystone.conf

  [database]
  connection = mysql://keystone:<KEYSTONE_DB_PASS>@controller/keystone

  - provide a suitable password for keystone user

• delete the default SQLite database which comes during Ubuntu installation

  - rm /var/lib/keystone/keystone.db

• create a keystone database user

  - mysql -u root -p
  - CREATE DATABASE keystone;
  - GRANT ALL PRIVILEDGES ON keystone.* TO 'keystone'@'localhost'  \
     IDENTIFIED BY 'KEYSTONE_DBPASS';
  - GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%'  \
     IDENTIFIED BY 'KEYSTONE_DBPASS';
