Django app deployment digitalocean stuck at nginx home page - django

Question

I have followed the DigitalOcean tutorial to deploy a django app at DigitalOcean, the guide is:
https://www.digitalocean.com/community/tutorials/how-to-deploy-a-local-django-app-to-a-vps
Question:
The problem is that when I go to the IP with the browser, I see the Welcome to nginx page and not my django app.
Tutorial important points
Respect the tutorial, I have not seen the following error as tutorial says: server_names_hash, you should increase server_names_hash_bucket_size: 32
Another important difference between what I did and tutorial is that gunicorn_django --bind yourdomainorip.com:8001 did not work for me.
I use this statement to start gunicorn:
web: gunicorn --chdir code/computationalMarketing computationalMarketing.wsgi --log-file -
My configuration
At /etc/nginx/sites-enabled I have symlink called computationalMarketing that refers to /etc/nginx/sites-available/computationalMarketing
This files has the following lines:
server {
listen 127.0.0.1;
server_name 159.65.18.211;
error_log /var/log/nginx/localhost.error_log info;
root /var/www/localhost/htdocs;
location /static/ {
alias /opt/computationalMarketing/static/;
}
location / {
proxy_pass http://127.0.0.1:8001;
proxy_set_header X-Forwarded-Host $server_name;
proxy_set_header X-Real-IP $remote_addr;
add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"';
}
}
I have a virtualenv at /opt/computationalMarketing and inside this I have another computationalMarketing folder with the Git repo file.
This repo has the following structure:
My installations are:
sudo pip3 install numpy==1.13.3
sudo pip3 install pandas==0.22.0
sudo pip3 install scikit-learn==0.19.1
sudo pip3 install pymysql==0.8.1
sudo pip3 install psycopg2==2.7.3.2
sudo pip3 install django==2.0.5
sudo pip3 install django-connection-url==0.1.2
sudo pip3 install whitenoise==3.3.1
sudo pip3 install gunicorn==19.7.1
The database is a Postgresql, which I can connect without problem.
Can anyone guess why I am seeing the nginx page and not my django app?

Answer 1

You've told nginx to listen for this particular config on the localhost only. Don't do that. Remove that listen line altogether.
There are a few other weird things in your question. The command you claim to be using to start gunicorn is a Procfile instruction, it's not something you could actually run at the command line. What command are you actually using to start gunicorn? Whatever you use, you do need to tell it to serve on the same port that nginx is proxying to - in your case 8001.
