Opengrid website

Opengrid website. Needs flask (http://flask.pocoo.org/).

Installation on the droplet

Install uWSGI:

apt-get install uwsgi uwsgi-plugin-python

Configure it by adapting the path in the file opengrid.uwsgi.ini and then:

• Copy the file to /etc/uwsgi/apps-available/opengrid.ini
• Symlink it in /etc/uwsgi/apps-enabled

Flask will be run as the user www-data, therefore the following needs to be taken care of:

• Make sure the root path is rw by www-data, e.g.:

# ls -ld /usr/local/src/website/
drwxrwxr-x 5 root www-data 4096 May  4 19:54 /usr/local/src/website

• Make sure /path/to/hp_anonymous.pkl is writeable by www-data, e.g.:

# ls -ld /usr/local/src/website/hp_anonymous.pkl 
-rw-rw-r-- 1 root www-data 40472 May  4 19:47 /usr/local/src/website/hp_anonymous.pkl

Start uWSGI:

# service uwsgi start opengrid

Configure nginx by putting the following lines in the server block of /etc/nginx/sites-available/default:

location / {
	# First attempt to serve request as file, then
	# pass it to flask 
	try_files $uri @opengrid-flask;
	autoindex on;
}

location @opengrid-flask {
  include uwsgi_params;
  uwsgi_pass unix:/var/run/uwsgi/app/opengrid/socket;
}

# Serve /static/ from the directory of the website
location /static/ {
  root /usr/local/src/website;
}

Make sure the path to the website's code correct.
