我正在尝试使用以下代码将Node.js应用程序与MySQL数据库连接,该数据库可在远程服务器上很好地适用于另一个应用程序:
var mysql = require('mysql');
var con = mysql.createConnection({
host: "www.<dnw>.com",
port: <correct port number>,
user: "<correct Username>",
password: "<correct password>",
database: "<correct databasename>"
});
con.connect(function(err) {
if (err)
{
throw err;
}
});
con.end();
执行时,我收到此错误消息
/home/akiku/node/dnwbot/main.js:49
throw err;
^

您有什么线索吗?

检查您是否有权访问远程服务器数据库。尝试使用工作台或任何其他工具进行连接
答案 1 :(得分:0)
我终于找到了问题:服务器管理员在更深的服务器级别阻止了该端口,而该级别无法被Plesk访问。
