Question

我在具有静态IP地址的远程PC上安装了mysql。我想在另一个系统上访问该mysql服务器。我使用mysql工作台在另一台PC中创建了连接。在Workbench中，它工作正常，但是当我尝试使用Node.js进行连接时，这给了我错误。

nodejs中的代码：

var sql = require('mysql')
var connection = sql.createConnection({
    //properties
    host: 'static Ip of my remote Pc',
    user: 'username',
    password: 'password',
    database: 'myDB',
    connectionLimit : 100,
        waitForConnections : true,
        queueLimit :0,
        debug    :  true,
        wait_timeout : 28800,
        connect_timeout :10,
});

function handleDisconnect() {
    connection = sql.createConnection(connection)};

connection.connect(function (error) {
    //callback function
    if (error) {
        if(error.code === 'PROTOCOL_CONNECTION_LOST') { 
            handleDisconnect();}  
        else
            console.log('error', error);
        setTimeout(handleDisconnect, 2000);
    } else {
            console.log('connected');
        }
    });

错误：
