Infrastructure Design:<\/h2>\n

As for as infrastructure is concern, we are going to use OpenStack networking (neutron), total of three Ubuntu instance will be used here, will act as Controller, Network and Compute Node.<\/p>\n

OpenStack recommends below configurations for each node, with 64 bit host operating system.<\/p>\n

\u2022 Controller Node: 1 processor, 2 GB memory, and 5 GB storage
\n\u2022 Network Node: 1 processor, 512 MB memory, and 5 GB storage
\n\u2022 Compute Node: 1 processor, 2 GB memory, and 10 GB storage<\/p>\n

The following is the network configuration of each node.<\/p>\n\n\n\n\n\n\n
ROLE<\/th>\nNW CARD 1<\/th>\nNW CARD 2<\/th>\nNW CARD 3<\/th>\n<\/tr>\n
CONTROLLER NODE<\/th>\n192.168.12.21 \/ 24, GW=192.168.12.2
\n(MANAGEMENT NETWORK)<\/th>\n		NA<\/th>\nNA<\/th>\n<\/tr>\n
NETWORK NODE<\/th>\n192.168.12.22 \/ 24 GW=192.168.12.2
\n(MANAGEMENT NETWORK)<\/th>\n		192.168.11.22 \/ 24
\n(TUNNEL NETWORK)<\/th>\n		192.168.0.10 \/ 24 GW=192.168.0.1
\n(EXTERNAL NETWORK \u2013 DHCP ENABLED)<\/th>\n<\/tr>\n
COMPUTE NODE<\/th>\n192.168.12.23 \/ 24 GW=192.168.12.2
\n(MANAGEMENT NETWORK)<\/th>\n		192.168.11.23 \/ 24
\n(TUNNEL NETWORK)<\/th>\n		NA<\/th>\n<\/tr>\n<\/tbody>\n<\/table>\n

* Tunnel Network wont have a gateway ip in the configuration file, this network is used for internal communication between Network Node and Compute Node.<\/p>\n

Add a host entry, so that nodes can use hostname to communicate instead of ip address. Place it on all nodes.<\/p>\n

# nano .\/etc\/hosts\n\n# controller\n192.168.12.21 controller\n# network\n192.168.12.22 network\n# compute\n192.168.12.23 compute<\/pre>\n
Once you have done with configuring ip address, ping between nodes to verify the connectivity.<\/p>\n
NTP Server:<\/h2>\n
Install and configure NTP on Controller Node so that all other nodes can do time sync.<\/p>\n
# apt-get install ntp\n# service ntp restart<\/pre>\n
Client NTP Configuration<\/h2>\n
Install NTP package on both Network and Compute node<\/p>\n
# apt-get install ntp<\/pre>\n
Edit the below configuration file.<\/p>\n
# nano \/etc\/ntp.conf<\/pre>\n
Remove other ntp servers from the file, just hash out the lines that are starts with word server. Add below entry to get our nodes sync with controller node.<\/p>\n
server controller<\/pre>\n
Restart the NTP service.<\/p>\n
# service ntp restart<\/pre>\n
OpenStack packages:<\/h2>\n
Install the Ubuntu Cloud archive keyring and repository.<\/p>\n
# apt-get install ubuntu-cloud-keyring\n\n# echo \"deb http:\/\/ubuntu-cloud.archive.canonical.com\/ubuntu\" \"trusty-updates\/kilo main\" > \/etc\/apt\/sources.list.d\/cloudarchive-kilo.list<\/pre>\n
Upgrade your system.<\/p>\n
# apt-get update && apt-get dist-upgrade<\/pre>\n
Do the above two steps on all nodes.<\/p>\n
Install MySQL database:<\/h2>\n
OpenStack components uses MySQL database to store information, so install MySQL on the Controller Node.<\/p>\n
# apt-get install mariadb-server python-mysqldb<\/pre>\n
Installer invokes a command line tui to set MySQL root password.<\/p>\n
# nano \/etc\/mysql\/conf.d\/mysqld_openstack.cnf<\/pre>\n
Add the following values and ensure bind-address value is set to management ip address of controller node to allow other node can access MySQL instance.<\/p>\n
[mysqld]\n## Set to Management IP\nbind-address = 192.168.12.21\ndefault-storage-engine = innodb\ninnodb_file_per_table\ncollation-server = utf8_general_ci\ninit-connect = 'SET NAMES utf8'\ncharacter-set-server = utf8<\/pre>\n
Restart the MySQL.<\/p>\n
# service mysql restart<\/pre>\n
Install RabbitMQ:<\/h2>\n
RabbitMQ is used by OpenStack to coordinate operations and status information among services. Install it on controller node.<\/p>\n
# apt-get install rabbitmq-server<\/pre>\n
Add openstack user.<\/p>\n
# rabbitmqctl add_user openstack password<\/pre>\n
* Replace password with your own password.<\/p>\n
Allow openstack user to read, write and configuration access.<\/p>\n
# rabbitmqctl set_permissions openstack \".*\" \".*\" \".*\"<\/pre>\n
Next is to configure KeyStone (OpenStack identity) service.<\/p>\n","protected":false},"excerpt":{"rendered":"
