            rewrite (.*) $1/index.html break;
        }
        if (-f $request_filename.html) {
            rewrite (.*) $1.html break;
        }
        if (!-f $request_filename) {
            proxy_pass http://thin;
            break;
        }
    }

Install thin service
sudo thin install
Installing thin service at /etc/init.d/thin ...
mkdir -p /etc/init.d
writing /etc/init.d/thin
chmod +x /etc/init.d/thin
mkdir -p /etc/thin

Configure thin to start at system boot
sudo /usr/sbin/update-rc.d -f thin defaults

Then put your config files in /etc/thin
sudo /usr/sbin/update-rc.d -f thin defaults
update-rc.d: warning: thin stop runlevel arguments (0 1 6) do not match LSB Default-Stop values (S 0 1 6)
 Adding system startup for /etc/init.d/thin ...
   /etc/rc0.d/K20thin -> ../init.d/thin
   /etc/rc1.d/K20thin -> ../init.d/thin
   /etc/rc6.d/K20thin -> ../init.d/thin
   /etc/rc2.d/S20thin -> ../init.d/thin
   /etc/rc3.d/S20thin -> ../init.d/thin
   /etc/rc4.d/S20thin -> ../init.d/thin
   /etc/rc5.d/S20thin -> ../init.d/thin

Create thin configuration
sudo thin config -C /etc/thin/<config-name>.yml -c <rails-app-root-path> --servers <number-of-threads> -e <environment>
</environment></number-of-threads></rails-app-root-path></config-name>

In my case,
sudo thin config -C /etc/thin/rails_app.yml -c /home/sandip/rails_app --servers 3 -e production
&gt;&gt; Wrote configuration to /etc/thin/rails_app.yml

thin configuration file will look like

Start/stop/restart Nginx &amp; thin server using command

sudo service nginx start|stop|restart
sudo service thin start|stop|restart
