How to add a user with all privileges to MariaDB

Replace newuser with your desired username:

Copy
mysql -uroot -p CREATE USER 'newuser'@'localhost' IDENTIFIED BY ''; GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost'; FLUSH PRIVILEGES; exit;

Remove password from an existing user

If you already have a user with sufficient privileges but protected by a password, you can remove the password.
Replace existinguser with your desired username:

Copy
mysql -uroot -p SET PASSWORD FOR existinguser@localhost=''; FLUSH PRIVILEGES; exit;

Add a user with unix socket authentication

The mysql client will use the underlying operating system credentials of your user account. You don't have to enter a password.

Replace newuser with the username of your account:

Copy
whoami newuser mysql -uroot -p DROP USER IF EXISTS 'newuser'@'localhost'; CREATE USER 'newuser'@'localhost' IDENTIFIED VIA unix_socket; GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost'; FLUSH PRIVILEGES; exit;

Add a user with password

Replace newuser with your desired username:

Copy
mysql -uroot -p CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'changeme'; GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost'; FLUSH PRIVILEGES; exit;

If you don't have a user with the sufficient access rights, follow these steps to reset the password.
