Instruction for running the app on DigitalOcean Django droplet

When logging into the server vis ssh, log into django not root user.

Install Anaconda Python 3.6 on the server

1. the labelling tool requires :

pip install --upgrade pip

sudo pip --no-cache-dir install scipy

If there are some problems with some packages use the no cache argument when installing scipy.

sudo pip install scikit-image

2. from image label tool directory run:

sudo python setup.py install

3. edit the django_project settings.py, url.py, admin.py, etc.

In settings.py:

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'django_project/static')

MEDIA_ROOT = os.path.join(BASE_DIR, 'django_project/media')
MEDIA_URL = '/media/'

4. add the example_labeller application in django_project directory: sudo python manage.py startapp example_labeller

5. edit the /usr/local/lib/python2.7/dist-packages/Image_labelling_tool-0.1.dev1-py2.7.egg/image_labelling_tool/labelling_tool_views.py file as follows:

Comment ->  from django.views import View
Add ->	from django.views.generic import TemplateView
And change -> class LabellingToolView (TemplateView):  # View to TemplateView

---

ONLY for slqlite:

6. Run:

sudo python manage.py migrate

7. copy static folder to django_project/django_project, also copy "jquery" folder from ext_static to static in django project

8. Run:

sudo python manage.py collectstatic

9. change the database from read only to read-write by -> sudo chown django:django db.sqlite3

10. Add some images:

1. make a folder in django/ e.g. 'images' and copy your images to it.
2. Run: sudo python manage.py populate ../images

11. sudo python manage.py createsuperuser ; and log in

Ensuring SLL and HTTPS: Get a domain name and set it up (in DigitalOcean and Domain service (like Google)). And just watch this video: https://www.youtube.com/watch?v=z0L3u2Vn3Wo

sudo apt-get update

sudo apt-get install git

cd /home/django/django_project/

git clone https://github.com/letsencrypt/letsencrypt

cd letsencrypt

sudo ./letsencrypt-auto --help

service nginx stop

sudo ./letsencrypt-auto certonly --standalone -d freeman.systems #the last argument is the domain name

sudo nano /etc/nginx/sites-available/django

	And change -> server {
			comment	->	#listen 80 default_server;
			comment	->	#listen [::]:80 default_server ipv6only=on;
			add	->	listen 443 ssl;

			add	->	server_name freeman.systems;
			add	->	ssl_certificate /etc/letsencrypt/live/freeman.systems/fullchain.pem;
			add	->	ssl_certificate_key /etc/letsencrypt/live/freeman.systems/privkey.pem;
		
                    At the end add: (use 4 spaces for indentation)
				server {
						listen 80;
						server_name freeman.systems;
						return 301 https://$host$request_uri;

				}

service nginx restart

DONE! HTTPS Encryption ENABLED

12. In settings.py add security exception -> X_FRAME_OPTIONS = 'ALLOW-FROM https://workersandbox.mturk.com' to allow the page to be displayed in the MTurk frame.

This is for sandbox mode.

IMPORTATNT: In produciton mode add the correct AMT address: 'ALLOW-FROM https://www.mturk.com'

13. PostgreSQL setup:

1. This should be already done by default, but somethings wrong: Disable Firewall on port 5432 -> sudo ufw allow 5432

2. Allow the TCP/IP through port 5432 on the host IP:

sudo find / -type f -name "pg_hba.conf"

nano pg_hba.conf

add this line to pg_hba.conf, where x.x.x.x is the host IP ->: host all all x.x.x.x/24 trust

nano postgresql.conf

add this line to postgresql.conf ->: listen_addresses = '*'
