SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:3306

Question

I'm using Sequelize as an ORM to my node js app and Mysql database , after following some tutorials i m adding this code to connect mysql to the node but after taping npm start i m getting this error : Unable to connect to the database: { SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:3306

 const Sequelize = require('sequelize');

 // Option 1: Passing parameters separately
 const sequelize = new Sequelize('Education', 'root','', {
 host: '127.0.0.1',
 dialect: 'mysql'
 } );

  //test db 
 sequelize
.authenticate()
.then(() => {
  console.log('Connection has been established successfully.');
})
 .catch(err => {
 console.error('Unable to connect to the database:', err);
});

Solution 1

Problem solved i was using port : 3307 in phpMyadmin instead of 3306

Solution 2

Add socketPath in the dialect options

Example code snippet:

// Option 1: Passing parameters separately
const sequelize = new Sequelize('Education', 'root', '', {
  host: '127.0.0.1',
  dialect: 'mysql',
  dialectOptions: {
    socketPath: '/Applications/MAMP/tmp/mysql/mysql.sock'
  }
});

Removing the port option could work only in your set-up. As the author mentioned afterwards, on their set-up their port was different than the default, and thus was the connection error.
