Need assistance with accessing mysql database using node.js

Question

I am trying to run a simple node sample for access a mysql db and am getting the following error-Error: ER_ACCESS_DENIED_ERROR: Access denied for user \'root\'@\'ubuntu.loca

Answer 1

Actually the solution is easier than you think. Change the host to 127.0.0.1 for the database connection.

Answer 2

I had a similar problem,my nodejs project.I was using knex.js for querybuilder and it's configuration.

This problem occurs when host value is 127.0.0.1,when i changed to 127.0.0.1 to localhost,the problem is gone away.

var knex = require('knex')({
    client: 'mysql',
    connection: {
        **host: 'localhost',**
        user: 'userNew',
        password: 'password',
        database: 'appDb'
    }
});

Answer 3

I was getting the exact same issue. I was not able to connect via the mysql module in nodejs, but was able to connect via the mysql client in the terminal (mysql -u root -p1111 -h localhost mydb)

It turns out, the mysql module converts "localhost" to 127.0.0.1. This would not work via the (mysql -u root -p1111 -h 127.0.0.1 mydb). See Issue 734

So I had to set a password for 127.0.0.1 in MySQL and it solved the problem.

Instructions

Connect to mysql via the console:

mysql -u root -p mysql

And Run

SET PASSWORD FOR 'root'@'127.0.0.1' = PASSWORD('Add-Your_password-here');

Answer 4

The user might not have any administrative role assigned so he is not able to access the database. The user will need at least the SELECT privilege to connect.

Answer 5

I've been on this problem for a long time now and among all forums I did, one simple solution resolve my issue. My password was with some special character. I change it to a simpler one like "onlyletters" and it works perfectly. Probably a encoding problem in the nodejs mysql module, I can... Hope it would help some of you guys...

Answer 6

I had a similar problem where I was getting the same error.

The answer for me ended up being that I was using a different port. By default, mysql expects a port of 3306, but I was using MAMP, where the MySQL server port was specified as 8889. As soon as I added a port definition to my database connection, it was fine:

var connection = mysql.createConnection({
    port: 8889,
    user: 'root',
    password : 'password',
    database : 'my_database'
});

NOTE: This is for Mac using MAMP, haven't tried it on ubuntu or Windows.
