3. Add users, set permissions

Create user command

mysql>create user [email protected] identified by ' password ';

Direct creation of user and authorized commands

Mysql>grant all on * * to [e-mail protected] indentified by ' password ';

Grant access to the extranet

Mysql>grant all privileges on * * to [e-mail protected] '% ' identified by ' password ';

Grant permissions and can authorize

Mysql>grant all privileges on * * to [e-mail protected] ' hostname ' identified by ' password ' with GRANT option;

Where only partial permissions are granted to change all privileges or all to Select,insert,update,delete,create,drop,index,alter,grant,references,reload, Shutdown,process,file part of it.
