Configuração NGINX (Rails)

default

# etc/nginx/sites-enabled/default
server {
	listen 80;

	server_name _;
	
	location / {
		proxy_pass http://localhost:3000;
		proxy_http_version 1.1;
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header Connection 'upgrade';
		proxy_set_header Host $host;
		proxy_cache_bypass $http_upgrade;
	}
}

tail -f /var/log/nginx/domain1.access.log

you can get your production.log working by starting your rails server like:

RAILS_ENV=production rails s >> log/production.log
