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 <https://docs.openstack.org/>`_ 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**::

    {
       "version": 2,
       "controller": {

                                }
                            }
                         ]
                      }
                   ]

                }
             ]
          }
       ]
    }

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

    nano /etc/systemd/system/crossbar.service

**crossbar.service**::

    [Unit]
    Description=Crossbar.io
    After=network.target

    Type=simple
    User=root
    Group=root
    StandardInput=null

    [Install]
    WantedBy=multi-user.target

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
