启动我的 node.js 应用程序时出现错误 connect ECONNREFUSED 127.0.0.1:3306

Question

When I start my node.js app I get this error:

SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:3306

What I was doing:

 - create a user:
CREATE USER 'main'@'localhost' IDENTIFIED BY 'myPass';

 - give this user all privileges
GRANT ALL PRIVILEGES ON *.* TO 'main'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;

I then try to connect through my code on production and it gives me an error: connect ECONNREFUSED 127.0.0.1:3306.

But in my localhost environment it connects well. And when I try to connect to DB using command line on VPS it works too: mysql -umain -p

I can't connect with code. But on my localhost it connects. Double checked my loggin and pass for DB user in .env.

Answer 1

尝试重新启动 MySQL 服务。

Answer 2

I found a problem! In my mysql config file (etc/my.cnf) was bind-address = my VPS ip So, when I remove this line it starts to listen al ips.

Thanks every one!

Just in case you fall into my category, I simply forgot to put on my local server (XAMMP). You might want to check if your MySQL server is active.

Answer 4

I had the same problem and solved it by adding "socketPath" to my sequelize deceleration like this:

const sequelize = new Sequelize('db-name', 'user', 'password', {
  host: 'localhost',
  dialect: 'mysql',
  dialectOptions: {
    socketPath: 'your socket path',
    supportBigNumbers: true,
    bigNumberStrings: true
  },
});

find your socket path by entering /etc/mysql/mysqld.cnf: then you have their your socket path:

user        = mysql
# pid-file  = /var/run/mysqld/mysqld.pid
# socket    = /var/run/mysqld/mysqld.sock
# port      = 3306
# datadir   = /var/lib/mysql
