Create MySQL User: A Comprehensive Guide

Welcome to our comprehensive guide on managing MySQL users for effective database administration. Whether you’re creating new users, updating passwords, or adjusting privileges, our step-by-step instructions ensure a seamless user management experience.

Create MySQL User

Step 1

Access MySQL by logging in with a privileged account.

CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';

Step 2

Grant the necessary privileges to the user based on your requirements. Optionally, tailor the user’s access for specific databases and operations.

GRANT ALL PRIVILEGES ON *.* TO 'newuser'@'localhost';

For more granular control, consider these optional privileges:

• Database-Specific Privileges

GRANT ALL PRIVILEGES ON `database_name`.* TO 'newuser'@'localhost';

• Table-Specific Privileges

GRANT SELECT, INSERT ON `database_name`.`table_name` TO 'newuser'@'localhost';

• Custom Privileges

GRANT SELECT, UPDATE, DELETE ON `database_name`.* TO 'newuser'@'localhost';

Step 3

Apply the changes to the user privileges.

FLUSH PRIVILEGES;

Access Your MySQL Database

Congratulations! You’ve successfully created a MySQL user. Access your MySQL database with the new user for efficient data management.

mysql -u newuser -p

Update MySQL User Password and Privileges

Update Password

To update the password for an existing user:

ALTER USER 'existinguser'@'localhost' IDENTIFIED BY 'newpassword';

Update Privileges

To update privileges for an existing user, modify the desired privileges using the GRANT and REVOKE statements:

GRANT SELECT ON `database_name`.* TO 'existinguser'@'localhost';
REVOKE INSERT ON `database_name`.`table_name` FROM 'existinguser'@'localhost';

Apply Changes

After updating the password or privileges, remember to apply the changes:

FLUSH PRIVILEGES;
