3. Add users, set permissions

Create user command

MySQL>user username'password';

Direct creation of user and authorized commands

MySQL>*.  To username'password';     

Grant access to the extranet

MySQL>*.  to [email protected]'%'password';       

Grant permissions and can authorize

MySQL>*.  to [email protected]' hostname'passwordoption;      

Simple user and permission configuration is basically the case.

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.
