Q:

Ip4address not working for node-mysql connection ubuntu

I am able to open phpmyadmin with both localhost as well as my IP4 address:

http://localhost/phpmyadmin 
http://192.168.3.72/phpmyadmin
http://127.0.0.1/phpmyadmin/

All the above Works
But when i try to apply IP4 address to this 
var mysql      = require('mysql');
var connection = mysql.createConnection({
  host     : 'localhost',
  user     : 'me',
  password : 'secret'
});

Reference : https://github.com/felixge/node-mysql/#introduction
I get error as :   
{ [Error: connect ECONNREFUSED]
  code: 'ECONNREFUSED',
  errno: 'ECONNREFUSED',
  syscall: 'connect',
  fatal: true }

What am i doing wrong?
Ports which are used are:
Active Internet connections (only servers)

I tried with netstat -nlt | grep 3306
But i get blank output instead of :
mysqld  1046  mysql  10u  IPv4  5203  0t0  TCP  xxx.xxx.xxx.xxx:3306 (LISTEN)

When tried with this post:
 Remote Connections Mysql Ubuntu
But when tried with : netstat -tulpn | grep :3306
I get output as:
tcp        0      0 192.168.3.72:3306       0.0.0.0:*               LISTEN      -  

Can anybody please assist with this... 

A:

I finally was able to solve the problem :-)

I logged in as root using sudo su
Edited subl /etc/mysql/my.cnf & Replace bind-address with my IP4 address
Run :  service mysql restart

Finally it gave me result as:
mysql stop/waiting
mysql start/running, process 12210

And now i am able to login successfully using IP4 address from external sources.
Thanks for all :-)
