Am trying to connect to a Mysql remote server using nodejs + selenium-webdriver.
The host am trying to connect is this: phpmyadmin.locaweb.com.br
If you acess this site, you will be able to see 3 fields to complete: Server,
User and Pass.
In my code, i do not know how to include the "Server". Looking in the web, i found the "localAdress" to pass as connection option, but is not working.
What i got so far:
//DB - config
var con = mysql.createConnection({
connectionLimit : 10,
host: "phpmyadmin.locaweb.com.br",
localAddress: "*****.mysql.dbaas.com.br",
user: "******",
password: "******",
port: 3306,
database: "*****"
});
con.connect(function(err){
if(err){
console.log('Error connecting to Db');
console.log(err);
return;
}
console.log('Connection established');
});
Error:
Error connecting to Db

your problem might be in the connection parameters, you are setting your password: 'root'.
In my experience the password usually is left blank: password: ''.
I am able to resolve it.i have check and find my Mamp server was running on 8889
so i have added one more variable in connetion port: '8889' at it works.
I am total beginner to database.
I am using localhost(127.0.0.1) with port 9090.
I successfully created mysql database, ran/used it in windows 10 command prompt and MySQL Workbench.
But when I try to run it with node.js, I fail to connect to server.
Below is index.js file I tried to run in windows command line.
var mysql = require('mysql');
var client = mysql.createConnection({
user:'root',
password:'password',
});
client.query('USE mydb');
client.query('SELECT * FROM PRODUCTS',function(error, result, fields){
if(error){
console.log(error);
} else{
console.log(result);
}
});
And it results in this error.

I am at the stage not knowing what I am not knowing.
I tried to change port in createConnection() function like this
var client = mysql.createConnection({
user:'root',
password:'password',
port: '9090'
});
Then I get this error.

1.Open your windows terminal and login :
mysql -uroot -p
( then type you password )
use mysql;
update user set authentication_string=password(''), plugin='mysql_native_password' where user='root';
4 Restart you mysql db : sudo service mysql restart
Doing this in MySQL Workbench solved the problem.
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password
BY 'YourRootPassword';
FLUSH PRIVILEGES;
I have a virtual machine on which is install ubuntu server with mysql and phpmyadmin I try to connect through express node js.
If I type 192.168.11.120/phpmyadmin (virtual machine address in the network) on the physical machine's browser, I can access it.
After doing a npm install mysql, it's my code
var mysql = require('mysql');
var connection = mysql.createConnection({
host : '192.168.11.120',
user : 'test',
password : 'test'
});
connection.connect();
connection.query('SELECT 1 + 1 AS solution', function(err, rows, fields)
{
if (err) {console.log(err)} ;
});
connection.end();
The console shows me the following error after doing a "node index.js".

Seems like your database is not running on port 3306.
Try and find out the port number and add the port attribute so your code is like this:
var db = mysql.createConnection({
host: "127.0.0.1",
user: "root",
password: "",
database: "udit1",
port: YOUR_PORT_NUMBER_HERE
});
I'm trying to establish a MySQL connection with my node.js server, but when I do, I get the following error:
F:\Programmering\nodejs-server>node dbConnection.js
F:\Programmering\nodejs-server\dbConnection.js:10
if (err) throw err;

I've tried using other ports, but still same error message. When I use XAMPP, and start MySQL service, it connects fine. These are the messages when I install mysql using npm:
F:\Programmering\nodejs-server>npm install mysql
npm WARN nodejs-server#1.0.0 No repository field.
+ mysql#2.15.0
added 11 packages in 7.809s
I have been using the w3schools tutorial. This is my code:
var mysql = require('mysql');
var con = mysql.createConnection({
host: "localhost",
user: "myusername",
password: "mypassword"
});
con.connect(function(err) {
if (err) throw err;
console.log("Connected!");
});
What am I doing wrong? Please help! Thank you!
