You can then create a new user by running the following command:
- CREATE USER ‘username’@’localhost’ IDENTIFIED BY ‘password’;
- Next, you need to grant the user permissions to the database by running the following command:
- GRANT ALL PRIVILEGES ON mydatabase.* TO ‘username’@’localhost’;
You can then connect to the MySQL server by running the following command:
- mysql -u ‘username’ -p mydatabase
where ‘username’ is the username you created and ‘password’ is the password you set.
