I'm having issues while setting up nginx and Gunicorn on my local computer (not the server). I have a Django project and I want to be able to access it via http://localhost:8000/. Before my nginx was functional, my Gunicorn server was able to start successfully. However, once I got my nginx server configured, now my Gunicorn server won't start because nginx is already running on my localhost on port 8000. When I visit http://localhost:8000/ I get 500 - Internal Server Error. When I visit http://localhost:80/, however, I get Welcome to nginx! web page.
To configure nginx and Gunicorn, I followed this guide, skipping steps 5 to 7 (inclusive). I have to note that in my /etc/nginx the sites-available and sites-enabled directories didn't exist, so I had to make them.
I have only two files in my /etc/nginx/sites-available directory - default and mydjangoproject. Both have the same contents and both have their symbolic links in /etc/nginx/sites-enabled. Their contents are:
server {
listen 8000;
server_name 127.0.0.1;
location = /favicon.ico { access_log off; log_not_found off; }
location /production_static/ {
root /home/john/Documents/Django_projects/mydjangoproject/Version_2/mydjangoproject;
}
location / {
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://127.0.0.1:8000;
}
}
Here are the relevant parts of my Django project's settings.py file:
DEBUG = False
ALLOWED_HOSTS = ['*', '127.0.0.1', 'localhost']
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'production_static/')
MEDIA_ROOT = os.path.join(BASE_DIR,'media')
MEDIA_URL = '/media/'
STATICFILES_DIRS = [
BASE_DIR / "static",
]
Here is the error log from /var/log/nginx/error.log:

I Googled these errors, but came up with nothing. Can someone tell me why is my nginx displaying 500 - Internal server error and how can I get both Gunicorn and nginx to run on the same address and port (if that's even possible)?
As @iklinac mentions, you cant have two ports config to the same id. The port should be 80 like in the tutorial you mentioned. Not 8000 as you have in the original post.
server {
listen 80;
server_name server_domain_or_IP;
}
