Nginx - 4021#0 - Problems setting up - django

Question

-I'm using a virtual machine with Ubuntu 12.04.3 LTS
-I'm doing a Django project with Uwsgi + nginx
-I added "192.168.33.50 myproject.com" to my hosts file
-I started uwsgi + supervisor + nginx process
-When I'm trying to access to myproject.com, I'm getting this error in /var/log/nginx/error.log:
2013/11/13 07:43:21 [crit] 14741#0: *1 connect() to
unix:/tmp/uwsgi_myproject.sock failed (2: No such file or
directory) while connecting to upstream, client: 192.168.33.1, s$
Edition 1
This is my uwsgi.ini:
[uwsgi]
module = myproject.wsgi:application
master workers = 3
logto = /vagrant/log/uwsgi.log
socket = /tmp/uwsgi_myproject.sock
pidfile = /tmp/uwsgi_myproject.pid chmod-socket = 666
auto-procname need-app vacuum
Edition 2
If I execute this command in console:
uwsgi --ini /vagrant/uwsgi.ini --chdir /vagrant/myproject/ --socket
/tmp/uwsgi_myproject.sock --pidfile /tmp/myproject.pid
With that command, uwsgi starts and I can access to myproject.com but it's supossed that uwsgi starts with supervisor of django
Edition 3
This is myproject.conf in /etc/nginx/conf.d/
server {
listen 80;
charset utf-8;
sendfile off;
# ONIX files
client_max_body_size 100M;
location /media/imagen {
include uwsgi_params;
#The uwsgi_pass must comply with the details in supervisord.conf
uwsgi_pass unix:/tmp/uwsgi_myproject.sock;
}
location /media/resources/protected {
root /vagrant/myproject/myproject;
internal;
}
location /media {
root /vagrant/myproject/myproject;
}
location /static {
root /vagrant/myproject/myproject;
}
location / {
include uwsgi_params;
#The uwsgi_pass must comply with the details in supervisord.conf
uwsgi_pass unix:/tmp/uwsgi_myproject.sock;
uwsgi_read_timeout 300;
}
}

Answer 1

The problem was in the configuration of the supervisor. The supervisor wasn't loading the uwsgi process well.
