I am trying to stream audio using using nginx, unicorn, and rails 4. I am using following these two links : one and two and this is what I have got so far -->

nginx.conf 

 location /protected/ {
            internal;
            alias /$1/;     #should end up evaluating the same thing
    }

    location / {
            proxy_redirect off;
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Sendfile-Type X-Accel-Redirect;
            proxy_set_header X-Accel-Mapping ^/*=/protected/$1;
            proxy_pass http://127.0.0.1:<port>/;
    }

I send file from my controller as : 

send_file(/home/full/path/file.mp3, 
            :filename => "filename.mp3",
            :type => "audio/mpeg",
            :disposition => "inline",
            :stream => 'true',
            :buffer_size  => 4096)

Now, using unicorn and nginx I am able to listen to the song, but not seek. This was happening with out nginx as well. I want to be able to seek. This I found that putting these two lines in production.rb will solve the issue :

So now, in my production.rb I have :

config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # specifically for nginx
config.middleware.insert 0, Rack::Sendfile, config.action_dispatch.x_sendfile_header # make sure it loads before any other middleware

But now I get 403 Forbidden error. Any help anyone ?

Got the solution .. So basically Nginx works within the directory, so if yo cant cd to that directory with the nginx user, then you will get a 403 forbidden error. You can confirm by using stat.

sudo -u www-data stat /path

It will fail if nginx user cant get to that path. Then, you can use gpasswd command to add user to a group and solve the issue.
