Are localhost and 127.0.0.1 refering to the same? (/etc/hosts)

Yes, I checked that a number of times using both localhost and 127.0.0.1

Also

Code:

cat /etc/hosts
127.0.0.1	localhost
...

Yay!

The solution turns out to be:

Code:

port: '/var/run/mysqld/mysqld.sock'

Seems in this config, MySQL listens on a Unix socket not on a TCP socket.

Here is the final node.js test script (index.js):

Code:

var express = require("express");
var fs = require("fs");
var https = require("https");
var app = express();
require("dotenv").config();
const privateKey = fs.readFileSync(process.env.SSL_PRIVKEY, "utf8");
const certificate = fs.readFileSync(process.env.SSL_CERT, "utf8");
const ca = fs.readFileSync(process.env.SSL_CHAIN, "utf8");
const user = process.env.DATABASE_USER;
const password = process.env.DATABASE_PASSWORD;
const database = process.env.DATABASE_NAME;
const port = process.env.DATABASE_SOCKET;

app.get("/", function(req, res) {
  res.send("hello world");
});

app.get("/test", function(req, res) {
  var mysql = require("mysql");
  var con = mysql.createConnection({
    host: "127.0.0.1",
    user: user,
    password: password,
    database: database,
    port: port
  });

  con.connect(function(error) {
    if (error) {
      console.log(error);
      return;
    } else {
      con.query("SELECT username FROM user WHERE userid < 10", function(
        err,
        rows,
        fields
      ) {
        if (err) {
          console.log(err);
          return;
        } else {
          rows.forEach(function(result) {
            console.log(result.username);
          });
        }
      });
      con.end();
      res.send("MySQL Query Complete");
    }
  });
});

https
  .createServer(
    {
      key: privateKey,
      cert: certificate,
      ca: ca
    },
    app
  )
  .listen(8080, function(error) {
    if (error) {
      console.log(error);
    } else console.log("Example app listening on port 8080");
  });
