到的NodeJS MySQL連接錯誤

Question

我收到提示： 錯誤：錯誤：握手閒置超時

Answer 1

使用連接池：

var mysql = require('mysql'); 
var pool = mysql.createPool({ 
    host  : 'example.org', 
    user  : 'bob', 
    password : 'secret' 
}); 

pool.getConnection(function(err, connection) { 
    // Use the connection 
    connection.query('SELECT something FROM sometable', function(err, rows) { 
    // And done with the connection. 
    connection.release(); 

    // Don't use the connection here, it has been returned to the pool. 
    }); 
}); 

Answer 2

您可以使用node-mysql，它非常容易使用。我已經使用過一次，這裏是例子： -

var mysql  = require('mysql'); 
var connection = mysql.createConnection({ 
    host  : 'localhost', 
    user  : 'me', 
    password : 'secret', 
    database : 'my_db' 
}); 

connection.connect(); 

connection.query('SELECT 1 + 1 AS solution', function(err, rows, fields) { 
    if (err) throw err; 
    console.log('The solution is: ', rows[0].solution); 
}); 

connection.end();
