This article explains how to use the mysql program to perform common MySQL database administration tasks from the command line. Among these common tasks are the creation and deletion of databases, users, and tables.
User and database creation
Follow these steps to create a MySQL database and user:
- Log in to MySQL as the root user at the command line:
mysql -u root -p- Enter the MySQL root password after typing it.
- Enter the following command to create a database user. Replace username with the username you want to create, and password with the password for the user:
GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost' IDENTIFIED BY 'password';The preceding command grants the user full access to all databases. You can, however, grant specific permissions to maintain complete control over database access. To explicitly grant only the SELECT permission to a specific user, for example, use the following command:
GRANT SELECT ON *.* TO 'username'@'localhost';You would use the following command to grant the user all permissions only on the database named dbname:
GRANT ALL PRIVILEGES ON dbname.* TO 'username'@'localhost';More information on MySQL database permissions can be found at https://dev.mysql.com/doc/refman/5.5/en/grant.html.
