db: The db table defines database-level privileges.Any privileges defined by a plugin or component are registered in this table. global_grants: The global_grants table defines each user's dynamic global privileges.These privileges apply to the whole MySQL server and are not affected by the availability of any plugins or components. user: The user table defines each user's static global privileges.Here is a review the where MySQL keeps different types of privilege information as was covered in the introduction to MySQL authentication and authorization article: MySQL stores the information about which users have what privileges in a number of different tables in the mysql system database. If the user is missing any of the required privileges, an error will occur. ![]() If the user has been granted all of the privileges required to perform the action, MySQL executes the statements. In MySQL, the privilege system determines whether a user can execute a given command or not.Įach time a client attempts to perform an action, MySQL consults its information on the user's privileges to determine whether it should be allowed or not. This could be the common user that is configured during installation, or any other user with full privileges. To follow along with this guide, we will assume that you are using an account with full administrative privileges (including the GRANT OPTION privilege). SELECT on mysql.*: used to execute SHOW GRANTS for other accounts.whatever privileges you wish to assign to other users.GRANT OPTION: the GRANT OPTION privilege allows you to grant or revoke any privilege that you have been granted.To manage privileges for MySQL users, you need to have the following privileges: REVOKE: use to remove existing privileges from a user account.GRANT: use to assign new privileges to a user account.The most important commands we'll be using in this guide are the GRANT and REVOKE commands: To follow along with this guide, you'll need an account on a MySQL server with the appropriate privileges. In this guide, we will talk about how to use the GRANT and REVOKE commands to add and remove privileges from MySQL user accounts and implement access policies that match your requirements. MySQL has a robust privilege assignment system that allows you to implement access policies throughout your database system. Deciding who should have what access to which components and powers and then designing an implementation that enables those policies requires a good deal of thought and care.
