MySQL Access Denied Error: Troubleshooting and Resolution

When attempting to connect to MySQL through the command line, you may encounter the error "ERROR 1045 - Access denied for user 'root'@'localhost' (using password: YES)." This error prevents you from accessing the database, hindering your ability to manage and retrieve data.

To resolve this issue, consider the following troubleshooting steps:

1. Confirm Root Password: Ensure that you have set a root password for MySQL. If you have lost or forgotten the password, you can reset it by following these steps:

   • Stop MySQL.
   • Restart it with the "--skip-grant-tables" option: "mysqld_safe --skip-grant-tables."
   • Open a new terminal and run the MySQL client: "mysql -u root."
   • Reset the root password: "UPDATE mysql.user SET Password=PASSWORD('NEW_PASSWORD') WHERE User='root';"
   • Flush the privileges: "FLUSH PRIVILEGES;"
2. Ensure a Clean Uninstall: If you have uninstalled and reinstalled MySQL, delete any leftover files and directories from the previous installation. This will ensure a fresh start.
3. Check Environment: Ensure that all necessary system components, such as Apache and PHP, are properly installed and configured.

If you have followed these steps and still encounter the error, consider consulting the official MySQL documentation or seeking assistance from a MySQL expert.
