Django app with Nginx + uWSGI on Amazon EC2 - django

Question

I am trying to set a Django app on Amazon EC2 using Nginx + uWSGI.
Following basic these tutorials
https://uwsgi.readthedocs.org/en/latest/tutorials/Django_and_nginx.html
http://www.yaconiello.com/blog/setting-aws-ec2-instance-nginx-django-uwsgi-and-mysql/#sthash.TsdnEDM8.oK2geOwb.dpbs
Nginx welcome page appears ok, Instance is running, Loadbalancer is In Service, Route53 alias to loadbalancer. But I can't see my app...
It appears that the app is running. I have tested local and it works.
I typed on terminal
uwsgi --ini myproject_uwsgi.ini
And get this
[uWSGI] getting INI configuration from myproject_uwsgi.ini

And I try to see the error.log and I get nothing...

I have finally make my app works... first I made it works with TCP, test on port 8001 but the static files was getting error 404. So I want to have at least the app working through unix sockets even with no static files...
I started changing the nginx.conf and uwsgi.ini to sockets and started receiving error 502. Much better than yesterday errors (unable to connect).
Searching and reading through web and SO... found this 502 error with nginx + uwsgi +django
Can't vote neither comment. But thanks #zzart !!
So added to my uwsgi.ini
uid = www-data
gid = www-data
chmod-socket = 777
I have added yesterday the uid (www-data), gid(www-data) and chmod-socket = 664 or 644. But not worked for me on Amazon EC2. But 777 make it works and also static files working too.
Now I will drink a beer and tomorrow will change security groups, loadbalancer and route53.
Hope it helps others.

Simple Example used FastCGI Deamon in Amazon EC2
