Installation

By hand installation

These instructions assume a debian-based (JESSIE) install (raspbian, ubuntu, etc) on the pi or BBB.

Debian Setup

• sudo apt-get update
• sudo apt-get upgrade -y
• sudo apt-get install libpq-dev python-dev postgresql postgresql-client nginx supervisor python-virtualenv -y --force-yes

For BBB

• sudo apt-get install build-essential python-setuptools python-pip python-smbus -y

Create a virutalenv for kriek

• sudo mkdir /opt/kriek
• sudo chown pi /opt/kriek
• virtualenv /opt/kriek/env-kriek

clone the source code

• cd /opt/kriek/
• git clone https://github.com/jsproull/kriek.git

pip requirements

• /opt/kriek/env-kriek/bin/pip install -r /opt/kriek/kriek/requirements.txt

We use either wiringpi or Adafruit_BBIO depending on the platform

for Pi

• /opt/kriek/env-kriek/bin/pip install wiringpi

for BBB

• /opt/kriek/env-kriek/bin/pip install Adafruit_BBIO

Configure postgres

• sudo su postgres -c /opt/kriek/kriek/shell/psql.sh

Configure the django kriek installation

• cd /opt/kriek/kriek
• ./manage.py syncdb --noinput
• echo "from django.contrib.auth.models import User; User.objects.create_superuser('pi', 'pi@example.com', 'pi')" | ./manage.py shell
• sudo ./manage.py collectstatic

then set up gunicorn, supervisord and nginx

• sudo rm /etc/nginx/sites-enabled/default
• sudo cp -R /opt/kriek/kriek/conf/ngnix/* /etc/nginx/
• sudo cp -R /opt/kriek/kriek/conf/supervisor/conf.d/* /etc/supervisor/conf.d/

And set up the required modules

For Pi

• sudo sh -c "echo '#one wire\ndtoverlay=w1-gpio\n' >> /boot/config.txt"

Automatic installation

• sh < <(curl -s "https://raw.githubusercontent.com/jsproull/kriek/master/shell/install.sh”)

Common part for both methods

For BBB
