How to Fix \'SQLSTATE[HY000] [1698] Access denied for user \'root\'@\'localhost\'\' Error in Ubuntu 16.04?
Troubleshooting "SQLSTATE[HY000] [1698] Access denied for user 'root'@'localhost'" Error in Ubuntu 16.04
Introduction:
When attempting to access a MySQL database from PHP or phpMyAdmin, you may encounter the following error:
SQLSTATE[HY000] [1698] Access denied for user 'root'@'localhost'
This error indicates that the user attempting to connect to the database lacks the necessary privileges.
Solution:
A recent change in MySQL 5.7 prevents the root user from connecting to the database without elevated privileges. To resolve this issue, follow these steps:
- Create a New User with Privileges:
CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password'; GRANT ALL PRIVILEGES ON *.* TO 'newuser'@'localhost' WITH GRANT OPTION;
- Update Your PHP Code:
Modify the PHP code to connect using the new user credentials:
<code class="php">protected $name = 'newuser'; protected $pass = 'password';</code>
- Connect Using Sudo:
If you wish to continue using the root user, you will need to elevate your privileges by running commands with sudo:
<code class="sh">sudo mysql -u root</code>
Additional Considerations:
- Ensure that the new user has the required privileges for the database operations you intend to perform.
- If you encounter any further issues, consult the MySQL documentation or seek support from the MySQL community.
