I follow steps from the blog. Some steps cause me lot of troubles. So move to One-click Install Ruby On rails droplet. It works with the default project. But I want to run my project, using the sites-enabled conf.

All file are uploaded to :
1- /var/www/metribook/epicure-app
2- in /etc/nginx/sites-enabled I changed the default site config to the one in 1)
3- I got the same error when I restart nginx service with sudo: sudo service nginx restart
error: Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

I got the same error with the first Droplet. I already install Nginx with Passenger many times on EC2 but I cannot resolve this issue. Need some help.
