I am trying to deploy my website to aws ec2. It's in python/django and I want to learn how to deploy websites myself. I had some issues with aws's EBS so first I'd like to know how to do that manually. I decided to use gunicorn and nginx for this.
I can run the website using gunicorn on a virtual env and I created the following script in /home/ec2-user/gunicorn_start.bash:
#!/bin/bash
NAME="davidbiencom" # Name of the
application
DJANGODIR=/home/ec2-user/davidbien # Django project directory
SOCKFILE=/home/ec2-user/virtual/run/gunicorn.sock
USER=ec2-user
GROUP=ec2-user
NUM_WORKERS=3
DJANGO_SETTINGS_MODULE=davidbiencom.settings
DJANGO_WSGI_MODULE=davidbiencom.wsgi
echo "Starting $NAME as `whoami`"
# Activate the virtual environment
cd $DJANGODIR
source /home/ec2-user/virtual/bin/activate
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DJANGODIR:$PYTHONPATH
# Create the run directory if it doesn't exist
RUNDIR=$(dirname $SOCKFILE)
test -d $RUNDIR || mkdir -p $RUNDIR
# Start your Django Unicorn
# Programs meant to be run under supervisor should not daemonize themselves (do$
exec gunicorn ${DJANGO_WSGI_MODULE}:application \
--name $NAME \
--workers $NUM_WORKERS \
--user=$USER --group=$GROUP \
--bind=unix:$SOCKFILE \
--log-level=debug \
--log-file=-
This runs fine I believe as there are no errors. Next I install nginx and start the service. I confirm it's running as I get the welcome page. Next I do the following:
Go to /etc/nginx/nginx.conf and add the following to http
include /etc/nginx/sites-enabled/*.conf;
I then create two folders in /etc/nginx/ sites-available and sites-enabled. I create a file davidbien.conf and enter the following inside(UPDATED):
upstream app_server {
# fail_timeout=0 means we always retry an upstream even if it failed
# to return a good HTTP response
# for UNIX domain socket setups
server unix:/home/ec2-user/virtual/run/gunicorn.sock fail_timeout=0;
# for a TCP configuration
# server 192.168.0.7:8000 fail_timeout=0;
}
server {
listen 80;
server_name 35.176.185.50;
#Max upload size
client_max_body_size 75M; # adjust to taste
location /static/ {
root /home/ec2-user/davidbien/static;
}
location / {
# checks for static file, if not found proxy to app
try_files $uri @proxy_to_app;
}
location @proxy_to_app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
# enable this if and only if you use HTTPS
# proxy_set_header X-Forwarded-Proto https;
proxy_set_header Host $http_host;
# we don't want nginx trying to do something clever with
# redirects, we set the Host: header above already.
proxy_redirect off;
proxy_pass http://app_server;
}
}
I save this file and run the following command:
ln -s /etc/nginx/sites-available/davidbiencom.conf /etc/nginx/sites-enabled/davidbiencom.conf
After this is done I restart nginx and I when I enter the ip address I get 502 bad gateway error.
What could be wrong here? Thank you.

You're telling nginx that it has to forward the request to 127.0.0.1:3031 but from what I see from the script to start gunicorn, gunicorn is binded to a socket, if you will start your gunicorn worker on 127.0.0.1:3031 it should work
