ERROR 1698 (28000): Access denied for user "root"@"localhost"

MySQL Error 1698: Access Denied for User 'root'@'localhost'

So you're trying to log into your MySQL database using the root user, but you keep getting hit with the dreaded ERROR 1698 (28000): Access denied for user 'root'@'localhost' error. Frustrating, isn't it? Don't worry, you're not alone. This is a common issue that many server administrators and developers face. But fear not, because I'm here to help you troubleshoot and resolve this problem.

Understanding the Error

Before we dive into the solutions, let's quickly understand what this error message means. Essentially, it's telling you that the user 'root' is being denied access to the MySQL database from the localhost (your own machine). There could be a few reasons for this, such as incorrect credentials or insufficient privileges assigned to the root user.

Solution 1: Resetting the Root Password

One possible cause of this error is an incorrect or forgotten password for the root user. To fix this, you can try resetting the root password. Here's how:

1. Stop the MySQL service:

sudo service mysql stop

1. Start the MySQL service in safe mode with the --skip-grant-tables option:

sudo mysqld_safe --skip-grant-tables

1. Open a new terminal window and log into the MySQL database as the root user:

mysql -u root

1. Once logged in, execute the following command to change the root password:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';

Replace 'new_password' with your desired password.

1. Flush the privileges to apply the changes:

FLUSH PRIVILEGES;

1. Exit the MySQL prompt and stop the MySQL service in safe mode:

exit
sudo service mysql stop

1. Finally, start the MySQL service normally:

sudo service mysql start

Now, try logging in with the root user using the new password. Hopefully, this resolves the access denied error for you.

Solution 2: Granting Sufficient Privileges

Another reason for the access denied error could be that the root user doesn't have the necessary privileges to access the database. To address this, we can grant the appropriate privileges to the root user. Here's how:

1. Log into the MySQL database as a user with administrative privileges:

mysql -u admin_username -p

1. Enter your password when prompted.

2. Once logged in, execute the following command to grant all privileges to the root user:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION;

1. Flush the privileges to apply the changes:

FLUSH PRIVILEGES;

1. Exit the MySQL prompt:

EXIT;

Now, try logging in with the root user again. Hopefully, this time you will be granted access without any issues.

Solution 3: Checking MySQL Configuration

If the above solutions didn't work, there might be an issue with the MySQL configuration files. It's possible that the root user's permissions have been restricted or modified. To check and fix this:

1. Open the MySQL configuration file, usually located at /etc/mysql/mysql.conf.d/mysqld.cnf:

sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

1. Look for a section called [mysqld] and make sure it includes the following line:

skip-grant-tables

This line allows you to bypass the authentication checks temporarily.

1. Save the file and exit the editor.

2. Restart the MySQL service for the changes to take effect:

sudo service mysql restart

Now, try logging in with the root user once again. If this fixed the issue, you can revert the changes made to the configuration file by removing the skip-grant-tables line and restarting the MySQL service.
