[Mysql] Error: connect ECONNREFUSED 127.0.0.1:3306

Error: connect ECONNREFUSED 127.0.0.1:3306

 

 

mysql 이 실행되지 않을 때, 연결되지 않아서 발생하는 오류 

mysql을 제대로 설치하고 실행까지 잘 완료했는지 확인 필요

 

 

 

변수로 빼봄 > 안됨 

 

const mysql = require('mysql')

const connection = mysql.createConnection({
    host: process.env.DB_HOST,
    user: process.env.DB_USER,
    password: process.env.DB_PASSWORD,
    database: process.env.DB_DATABASE
})
connection.connect();
