I have set up my RoR app on DO Ubuntu x64. On Nginx port 8080.
My config:
server {
listen 8080;
# server_name www.mydomain.com;
passenger
You need to relax permissions to that the Nginx worker process can access your application directory, by making the directory group- and world-executable:
sudo chmod g+x,o+x /root/myapp/public;
sudo chmod g+x,o+x /root/myapp;
sudo chmod g+x,o+x /root;
and it's done. Good Luck!
