abiliazione user esterne a mysqlserver

[ugobale]

Ciao

Mi ricordo di un commando che abilitava con % tutte le user, che mi avevi suggerito ai tempi, ma nei miei appunti non lo trovo.
Penso sia possibile abilitare solo alcune user all’accesso di mysql server, ecco a che punto siamo :

ni253149,root,root # uname -a
Linux ni253149 2.6.32-279.el6.x86_64 #1 SMP Wed Jun 13 18:24:36 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux
ni253149,root,root # mysql -u root -p
Enter password:
