How to Fix MySQL Error - Access Denied for User 'root@localhost'

If you are encountering an error message that says “Access Denied for User ‘root@localhost'” when trying to access your MySQL database, don’t worry, you are not alone. This error message can be frustrating, but it is actually a common issue that can be easily fixed. In this tutorial, we will guide you through the steps to resolve this error.

Step 1: Check Your MySQL Credentials

The first thing you need to do is to check your MySQL credentials. Make sure that you are using the correct username and password to access your MySQL database. The default username for MySQL is ‘root’, and the default password is blank. If you have changed your username or password, make sure that you are using the correct one.

Step 2: Check Your MySQL Hostname

The next step is to check your MySQL hostname. By default, MySQL is configured to only allow connections from the localhost ( If you are trying to connect to your MySQL database from a remote host, you need to make sure that your MySQL server is configured to allow remote connections. To do this, you need to edit your MySQL configuration file (my.cnf) and add the following line under the [mysqld] section:

bind-address =

This will allow connections from any IP address. Once you have made this change, restart your MySQL server.

Step 3: Grant Access to MySQL User

If you are still encountering the “Access Denied for User ‘root@localhost'” error message, you may need to grant access to your MySQL user. To do this, log in to your MySQL server as the root user and run the following command:


Replace ‘your_password’ with your MySQL password. This command will grant all privileges to the root user for all databases and tables. If you want to grant access to a specific database, replace . with the name of the database (e.g. mydatabase.*).

Step 4: Flush Privileges

After granting access to your MySQL user, you need to flush the privileges. To do this, run the following command:


This will reload the grant tables and apply the changes that you made.

In this tutorial, we have shown you how to fix the “Access Denied for User ‘root@localhost'” error message in MySQL. By following these steps, you should be able to access your MySQL database without any issues. Remember to always check your credentials, hostname, and privileges to ensure that you have the correct access to your MySQL database.
