nginx can't link uwsgi - django

I have installed nginx successfully and uwsgi work well but when I want to link nginx with uwsgi.it's wrong
This is my nginx.conf and uwsgi.ini
server {
listen 80;
server_name localhost;
#charset koi8-r;
charset utf-8;
#access_log logs/host.access.log main;
location / {
include uwsgi_params;
uwsgi_pass 127.0.0.1:8000;
root html;
index index.html index.htm;
}
and
http=127.0.0.1:8000
#socket=/root/project/learning_log/nginx_uwsgi.socket
chdir=/root/project/learning_log/
#chmod-socket=664
master=true
processes=4
threads=2
module=learning_log.wsgi
#wsgi-file=uwsgi_test.py
#stats=127.0.0.1:8000
./nginx & uwsgi3 --ini /root/project/learning_log/uwsgi.ini
when I access 127.0.0.1,it's wrong
and the access.log:
127.0.0.1 - - [15/Jan/2018:18:06:13 +0800] "GET / HTTP/1.1" 504 537 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0"
the error.log:
2018/01/15 18:06:13 [error] 12986#0: *13 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", upstream: "uwsgi://127.0.0.1:8000", host: "127.0.0.1"

Nginx: 502 BAD GATEWAY while deploying django to AWS EC2 instance

I am trying to deploy a django website on aws EC2 instance with Nginx. I am getting the following error.
*1 connect() failed (111: Connection refused) while connecting to upstream, client: **.***.***.***, , server: **.**.***.*, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8000/", host: "*.amazonaws.com"
In /etc/nginx/sites-available folder I have a file with the following configurations
server{
listen 80;
server_name your_public_ip;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
root /home/ubuntu/mySiteFolder;
}
location / {
include proxy_params;
proxy_pass http://127.0.0.1:8000;
}
}
Where is the mistake that I am committing? Thank you in advance.

DigitalOcean add domain to django instance with nginx and gunicorn

I've setup the one click install django on digitalocean and added a domain to it. I'm also trying to add a sub domain before the site goes live. I've edited the nginx conf file as below
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
root /usr/share/nginx/html;
index index.html index.htm;
client_max_body_size 4G;
server_name beta.kazi-connect.com;
keepalive_timeout 5;
# Your Django project's media files - amend as required
location /media {
alias /home/django/django_project/django_project/media;
}
# your Django project's static files - amend as required
location /static {
alias /home/django/django_project/django_project/static;
}
# Proxy the static assests for the Django Admin panel
location /static/admin {
alias /usr/lib/python2.7/dist-packages/django/contrib/admin/static/admin/;
}
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
proxy_buffering off;
proxy_pass http://app_server;
}
}
upstream app_server {
server unix:/home/django/gunicorn.socket fail_timeout=0;
}
and restarted both nginx and gunicorn however when I visit the sub domain I get a 502 bad gateway error.
Nginx log states there's an issue with gunicorn.

Samuel's answer was right. The problem is that the domain names are not included in the ALLOWED_HOSTS. In the django_project/settings.py, search for the code below.
# Discover our IP address
ALLOWED_HOSTS = ip_addresses()
Add your domain name to ALLOWED_HOSTS, e.g.
ALLOWED_HOSTS.extend(["xyz.com"])

Django gunicorn nginx "connection reset by peer while reading response header"

trying to set up django with gunicorn and nginx, getting some weird errors from nginx:
2015/10/07 06:17:22 [error] 28817#0: *12 connect() to

nginx config:

location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
root /home/david/StockSearch/stocksearch;
}
location / {
include proxy_params;
proxy_pass http://unix:/home/david/StockSearch/stocksearch/stocksearch.sock;
}
}
gunicorn config:
start on runlevel [2345]
stop on runlevel [!2345]
respawn
setuid david
setgid www-data
chdir /home/david/StockSearch/stocksearch
exec /home/david/Env/ssenv/bin/gunicorn --workers 3 --bind unix:/home/david/StockSearch/stocksearch/stocksearch.sock stocksearch.wsgi:application

I'm very new to nginx and gunicorn, but i think you can't do that:
proxy_pass http://unix:/home/david/StockSearch/stocksearch/stocksearch.sock;
this is achived with fastCGI not with proxypass:
include fastcgi_params;
fastcgi_pass unix:/var/run/php5-fpm.sock;
astcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_nam$
I can tell how i configure my nginx and gunicorn in my server, i hope my configuration helps:
server {
server_name XX.XX.XX.XX;
access_log /webapps/Project/log/acces.log;
error_log /webapps/Project/log/error.log warn;
location /static/ {
root /webapps/Project;
}
location / {
proxy_pass http://127.0.0.1:8001;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM N$
}
}
then i start my gunicorn server in my local machine like:
gunicorn Project.wsgi:application --bind 127.0.0.1:8001

The above solution is not helping me.Can someone please help me.
Am stuck for a long time now.
Thanks

This means that your Thin servers are not running. Try this:
curl -v http://localhost:3000
It is probably not working. Look at your Thin logs (stdout/stderr.log) to identify further problems.
Thin is a separate process and it should be restarted individually. It is common to have it setup within your Rails app in the same bundle. In that case you need to run it like:
bundle exec thin start
See: http://code.macournoyer.com/thin/usage/
If you installed your Gems as root including the thin gem, then it should have installed an init script in /etc/init.d. In that case you can restart thin with the service command.
When you deploy new code, you only need to restart your thin servers and not nginx.

nginx+gunicorn+supervisor throwing intermittent HTTP 500 Errors

I have an application running nginx,django 1.5, gunicorn.
Scenario 1
When I load my application one time - it will show the page file with an underlying 200 HTTP response.
Scenario 2
However, if I reload this same page right after, it will show my HTTP 500 Default, but custom page.
Scenario X
If I reload again, it either will show Scenario 1 or Scenario 2 upon subsequent page reloads.
I looked at my access.log for nginx and...
it is showing information like for the 500 error page:
[05/Oct/2013:03:26:07 +0000] "GET / HTTP/1.1" 500 460 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:24.0) Gecko/20100101 Firefox/24.0"
