The following describes in detail how to authorize users.
mysql> grant permission 1, permission 2, ... permission n on database name. table name to user name@user address identified by 'connection password';
Permission 1, Permission 2,... Permission n represents 14 permissions such as select, insert, update, delete, create, drop, index, alter, grant, references, reload, shutdown, process, and file. When privilege 1, privilege 2, ... privilege n is replaced by all privileges or all, it means that all privileges are given to the user. When the database name and table name are replaced by . , it means that the user has the authority to operate all tables in all databases on the server. The user address can be localhost, or it can be an IP address, machine name, and domain name. You can also use '%' to connect from any address. 'Connection password' cannot be empty, otherwise the creation will fail.

mysql> grant all privileges on . to [email protected] identified by '123'; to assign the user joe from 10.163.225.87 the authority to perform all operations on all tables in all databases, and set the password to 123.
