The error basically means that some other application is using those default ports. You can check that using :

sudo netstat -tulpn

Get the PID of the process that already using that port and send signal with kill command.

sudo kill -2 <PID>
sudo service nginx restart

In my case apache httpd was running on the same port and I didn't want to kill that process so I changed the default port for nginx to some other port. This is how my nginx.conf looks now.

server {
    listen       3000 default_server;
    listen       [::]:3000 default_server;
    server_name  _;
    root         /usr/share/nginx/html;

    # Load configuration files for the default server block.
    include /etc/nginx/default.d/*.conf;

    location / {
    }

    error_page 404 /404.html;
        location = /40x.html {
    }

    error_page 500 502 503 504 /50x.html;
        location = /50x.html {
    }
}

Also, make sure that in this file, user is set as the user you are logged in as ( for ex root ).

If this is not the case, you can try other options mentioned here.

You can use nginx -t to test that the file nginx.conf is in correct syntax.
