Wndows 10 / Node.js无法连接到mySQL服务器

Question

I have a discord bot that has been connecting to my database as follows:

var con_database = mysql.createConnection({
host: "localhost",
user: "root",
password: "mypass",
database: "cordtrax"
});

It has been connecting flawlessly for days now, but suddenly when I start my bot with nodemon, I get the following error:

{ Error: connect ECONNREFUSED 127.0.0.1:3306
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1191:14)

errno: 'ECONNREFUSED',
code: 'ECONNREFUSED',
syscall: 'connect',

fatal: true }

The same error occurs when starting the bot using regular node. When I try to connect through my mySQL 8.0 command line client, the client closes instantly after inputting my password. When I try and connect through the command line using mysql -h localhost I get the following error:

ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)

Every guide I have seen so far recommends going to services and starting the mySQL service manually. When I try this, I get the pop up message saying the service has started and stopped.

Answer 1

I think MySQL Server is not installed properly. Install it fresh again. Then confirm that service is started. If Service is not started, you cannot connect.
