node.js mysql error: ECONNREFUSED

Question

Why can't I connect to the mysql server?

On the same server an Apache/PHP server is running and it connects without problems!?

var mysql_link = {
    host : 'localhost',
    port : 3308,
    database: 'nodetest',
    user : 'root',
    password : 'xxx'
};

var connection = mysql.createConnection(mysql_link);

connection.connect(function(err){
    console.log(err);
    if(err != null){
        response.write('Error connecting to mysql:' + err+'\n');
    }
});

connection.end();

error

{ [Error: connect ECONNREFUSED]
  code: 'ECONNREFUSED',
  errno: 'ECONNREFUSED',
  syscall: 'connect',
  fatal: true }

Answer 1

I know this question has been answered, but for me the problem was that the mysql server listens on a Unix socket not on a tcp socket. So the solution was to add:

port: '/var/run/mysqld/mysqld.sock'

to the connection options.
