Why is node script failing a localhost connect to MySQL - mysql

Question

I can't figure out why a script to is failing to connect to the MySQL instance.
I can connect to the database from the mysql client on the command line, with the exact same credentials.
I can connect to the database from a remote client, using the same credentials.
The database connect script works fine if I set the parameters to a remote database.
Neither host or socket parameters works through the script.
I make dumb mistakes at times but if this is another one, I can't see it.
An outside observer would help me here.
==================== DB Connect code
var db = require('./config');
var mysql = require('mysql');
var connection = mysql.createConnection({
host: db.db_parms.host,
port: db.db_parms.port,
user: db.db_parms.user,
password: db.db_parms.password,
database: db.db_parms.context,
debug:true
});
connection.connect(function(err) {
if(err){
console.log("SQL CONNECT ERROR: " + err);
} else {
console.log("SQL CONNECT SUCCESSFUL.");
}
});
connection.query("SELECT now()", function(error,results,fields) {
console.log("Results:" + results);
console.log("Fields:" + fields);
});
exports.connection = connection;

I'm not sure if the error from the socket is a permissions issue or not and if that is relevant.

Answer 1

As it turns out, a check of the my.conf shows that the bind-addresss was set to the IP of the server and not to localhost.
Setting host: '<ip-address>' fixed the issue.
