我无法运行服务器... ECONNREFUSED

如何解决这个错误！

当我尝试使用不同的端口时..所有人都给我同样的错误！

ubuntu@ip-MyIP:~/rainmelon/projects/FindMyBuffet$ node app.js
Express server listening on port 7005

Error: connect ECONNREFUSED
    at errnoException (net.js:884:11)

追溯表明异常来自何处：

Error: connect ECONNREFUSED
    at errnoException (net.js:884:11)
    at Object.afterConnect [as oncomplete] (net.js:875:19)
    --------------------
    ...
    at Connection.connect (.../node_modules/mysql/lib/Connection.js:73:18)
-->                                         ^^^^^

因此，您的应用程序无法连接到MySQL。

通常是由于您的MySQL驱动程序配置中的主机名/端口名不正确，MySQL服务器未运行，或者您的MySQL服务器未配置为侦听TCP套接字。看这里。
