Can't launch Rails app with Nginx and passenger

Installed nginx, passenger 4.0.17, node, rails 4 and ruby 2, git and all gems.

nginx config:

server {
        listen 80;
        server_name  162.243.1.111;
	root /home/abachuk/myapp/public;
	passenger_enabled on;
	rails_env production;
}

tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      1828/nginx ```

what else is missing?
