Hi I am using below code to connect with Mamp data base "http://localhost:8888/phpMyAdmin/server_databases.php?server=1" but not able to do it getting below error
code :-
const db = mysql.createConnection({
host: 'localhost',
user: 'root',
password: 'root',
database: 'nodejs.login',
})
db.connect((error) =>{
if(error){
console.log(error)
}else {
console.log("Mysql Connected....")
}
})
error:-

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;
im trying to connect mysql with nodejs but have error
i think its a mysql problem not nodejs .
this is the error

}
also i dont have mysql in my task manager
i think i did something but i got error before it disapeared
my js code is
const mysql = require('mysql');
var connection = mysql.createConnection({
host : 'localhost',
port : 3306,
user : 'root',
password : 'philipthe1',
database : 'todo'
});
connection.connect();
connection.query("select * from items",(error,res,fields)=>{
if(error){
console.error(error);
}
else{
console.log(res)
}
})
connection.end();
It is a mysql error, cuz it says you cannot connect to db.
Can you add the code in which you're trying to connect?
i was able to restart mysql by doing windows key and r on keyboard then services.msc
then it gave option start server
the docs for it is in mysql docs under restarting server
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".

IDE Screenshot
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 can't figure out why a script to is failing to connect to the MySQL instance.
I can connect to the database from the mysql client on the command line, with the exact same credentials.
I can connect to the database from a remote client, using the same credentials.
The database connect script works fine if I set the parameters to a remote database.
Neither host or socket parameters works through the script.
I make dumb mistakes at times but if this is another one, I can't see it.
An outside observer would help me here.

I'm not sure if the error from the socket is a permissions issue or not and if that is relevant.
As it turns out, a check of the my.conf shows that the bind-addresss was set to the IP of the server and not to localhost.
Setting host: '<ip-address>' fixed the issue.
