无法从 Node.js 应用程序连接到 MySQL DB

Question

im new to MYSQL and database programming in general. using mac im setting the mysql server with docker image by running this command:

docker run -d --name sql_server_demo -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=123123123' -p 1433:1433 microsoft/mssql-server-linux

the container is running and when i try to connect from command line like so:

mssql -u sa -p 123123123

it connects successfully and i can start typing queries. im also able to connect via Azure Data Studio as well.

the problem is when im trying to connect from node.js app like so:

var mysql = require('mysql');

const config = {
host: 'localhost',
user: 'sa',
password: 'reallyStrongPwd123',
database: 'logger',
port: '1433',
};

var con = mysql.createConnection(config);

con.connect(function (err) {
  if (err) throw err;
  console.log("Connected!");
});

i specify the port according to the docker mysql container and the callback from connect never happens. when i delete the port i get this error: Error: connect ECONNREFUSED 127.0.0.1:3306

any help would be appreciated here:) thanks!

您使用的是 MsSQL 服务器而不是 MySQL，因此您必须将 docker 映像更改为 mysql（或使用： https : //hub.docker.com/_/mysql ）此 NPM 模块https://www.npmjs.com/package /mssql
