connetti ECONNREFUSED - node js , sql

Conosco due modi per risolverlo:

1. In mysql.conf , commenta skip-networking .

2. Prova a impostare la presa in questo modo:

   var client = mysql.createClient({
   user: uuuu,
   password: pppp,
   host: '127.0.0.1',
   port: '3306',
   _socket: '/var/run/mysqld/mysqld.sock',});
