OpenStack Newton


14th release of OpenStack

Nova: Large scale deployment

Glance: Better security

Keystone: Easier hybrid cloud management

Swift: Improved operator capabilities

New Features

OpenStack Installation Environment


Major Steps

•Design the network (i.e. setup the IPs)

•Build the machines (i.e. the VMs)

•Start the control machine

• Install services

•For each service provided by other nodesConfigure those nodes

Verify control – and the other node config


Basic Services•MariaDB – backend mysql database

•RabbitMQ – queueing service

• Keystone – identity service

•Glance – image service

•Nova – compute service for cloud VMs

•Neutron – network service

•Horizon – dashboard and apache2

•Cinder – block storage linked into LVM2/26/2018 COMP4442 Cloud Computing Lab 06 © George Baciu 2018 9

Building the machines

•Build control node

• Install network, chrony, openstack client

•Clone control node to compute node

•Configure compute node network

•Build a new blockst node – disk partition

•Configure blockst node network and LVM


Install Services

•Back to control node

• Install mariaDB mysql database

• Install RabbitMQ

• Install Keystone

• Install Glance


Install Services (2)

•On the control node Install Nova compute service

•On the compute node Install Nova compute service

•On the control node Install Neutron network service

•On the compute node Install Neutron network service


Install Services (3)

•On the control node Install Horizon dashboard

•On the control node Install Cinder block storage service

•On the blockst node Install Cinder block storage service


Service Installation Loop


Register the service forauthentication in MariaDB

Start service

OKNOK

Verify installation Done

Get and installservice software

Set configuration parameters in/etc/<service>/*.conf

Sync the configurationin service DB

*** should perform this only ONCE!

Service Files

• /etc/<service>/*.conf

• /etc/<service>/plugins/*/*

• /var/log/<service>/*.log

• where <service> is one of:

rabbitmq, keystone, glance, nova, cinder, neutron, horizon


Use Virtual Share Folder

• For each node in {control, compute, blockst}

The service configuration files are in:

/media/vsh/SYS/UBU/config/<node>/<service>/etc/<service>

The service installation scripts are in:

/media/vsh/SYS/UBU/config/<node>/<service>/bsh/install

In each install folder, the main installation script is 00-install.bash


The Global Script

•For each VM, the main script for installing all

the services on the node is in:

/media/vsh/SYS/UBU/config/<node>/allinstall.bash


Final Notes!• Some steps require manual query in order to adjust the settings,

e.g. LVM in cinder service – must enquire the VM system to see

which device the LVM is on e.g. /dev/sda5

• Some steps should not be performed more than once e.g.

adding a DB/Table/User to the sql database.

• First read, then understand, then do!

• At last: every step should be verified!

• Problems: check the /var/log/<service>/* files


OpenStack Dashboard

•To access your cloud:Open a browser (Chrome, Firefox)

Type in the address bar:

http://10.10.10.10/horizon


Tools for VM Monitoring

• top # displays the top processes

• free –m # shows the memory allocation

• htop # a better version of all the above

•watch –n 5 free -m
