Basic scenario

For this installation of the Iotronic Service we are considering a scenario with the following hosts and softwares:

• Controller ( Ubuntu linux): Mysql, Keystone, Rabbitmq
• Iotronic ( Ubuntu linux ): Iotronic-conductor, iotronic-wamp-agent, crossbar
• Board: iotronic-lightining-rod

Controller host setup

According to the Openstack Documentation install the following softwares on the controller host:

• SQL database
• Message queue
• Memcached
• Keystone

Creation of the database

On the dbms create the iotronic db and configure the access for the user iotronic:

MariaDB [(none)]> CREATE DATABASE iotronic;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON iotronic.* TO iotronic@'localhost' IDENTIFIED BY ‘IOTRONIC_DBPASS’;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON iotronic.* TO iotronic@'%' IDENTIFIED BY ‘IOTRONIC_DBPASS’;

Add the user and the enpoints on Keystone:

openstack service create iot --name Iotronic
openstack user create --password-prompt iotronic
openstack role add --project service --user iotronic admin
openstack role create admin_iot_project
openstack role create manager_iot_project
openstack role create user_iot
openstack role add --project service --user iotronic admin_iot_project

openstack endpoint create --region RegionOne iot public http://IP_IOTRONIC:8812
openstack endpoint create --region RegionOne iot internal http://IP_IOTRONIC:8812
openstack endpoint create --region RegionOne iot admin http://1IP_IOTRONIC:8812

Configuring Iotronic Host

Crossbar

Install crossbar on the Iotronic host:

apt install python-pip python3-pip libsnappy-dev libssl-dev libffi-dev python-dev
pip3 install python-snappy crossbar

Configuration:

mkdir /etc/crossbar
nano /etc/crossbar/config.json

config.json:

}

Create a systemd service file /etc/systemd/system/crossbar.service:

nano /etc/systemd/system/crossbar.service

Iotronic Installation

Get the source:

git clone https://github.com/openstack/iotronic.git

add the user iotronic:

useradd -m -d /var/lib/iotronic iotronic

and Iotronic:

cd iotronic
pip3 install -r requirements.txt
python3 setup.py install

create a log dir:

mkdir -p /var/log/iotronic
chown -R iotronic:iotronic /var/log/iotronic/

edit /etc/iotronic/iotronic.conf with the correct configuration:

nano /etc/iotronic/iotronic.conf

There is just one wamp-agent and it must be set as the registration agent:

register_agent = True

populate the database:

iotronic-dbsync

API Service Configuration

Install apache and the other components:

sudo apt-get install apache2 python-setuptools libapache2-mod-wsgi-py3

create log directory:

touch /var/log/iotronic/iotronic-api_error.log
touch /var/log/iotronic/iotronic-api_access.log
chown -R iotronic:iotronic /var/log/iotronic/

copy the config apache2 file:

cp etc/apache2/iotronic.conf /etc/apache2/sites-available/iotronic.conf

enable the configuration:

a2ensite /etc/apache2/sites-available/iotronic.conf

restart apache:

systemctl restart apache2

Starting

On the wamp agent:

systemctl enable iotronic-wamp-agent
systemctl start iotronic-wamp-agent

On the conductor:

systemctl enable iotronic-conductor
systemctl start iotronic-conductor

Board Side
