uwsgi upstart on amazon linux

amazon-ec2, flask, nginx, upstart, uwsgi

Solution

To fix this I did a few things. - Moved all scripts from the home directory to an /var/www/ - created an www group and www user and chown /var/www to www:www

Full Instructions

Create a user and group www and www

sudo groupadd www
sudo adduser www -g www

create a dir where your flask application will be ie /var/www/

sudo chown -R www:www /var/www
