Node.js MySQL数据库连接超时(ETIMEDOUT)

const mysql = require('mysql');

const connection = mysql.createConnection({
  host: 'localhost',
  user: 'root',
  password: 'password',
  database: 'database',
  connectTimeout: 10000 // 设置连接超时时间为10秒
});

connection.connect((err) => {
  if (err) {
    console.error('Error connecting to MySQL database:', err);
    return;
  }
  console.log('Connected to MySQL database');
});

const mysql = require('mysql');

const pool = mysql.createPool({
  connectionLimit: 10, // 设置连接池的最大连接数
  host: 'localhost',
  user: 'root',
  password: 'password',
  database: 'database'
});

pool.getConnection((err, connection) => {
  if (err) {
    console.error('Error getting MySQL connection from pool:', err);
    return;
  }
  console.log('Connected to MySQL database');
  
  // 使用连接进行数据库操作
  
  connection.release(); // 释放连接回连接池
});
