Příklad
[editovat]Způsob užití si ukážeme na příkladu:
- Spuštění utility (jako root) - po zadání hesla nás utilita přivítá nápovědou:
$ mysql_setpermission -u root Password for user root to connect to MySQL: ********** ###################################################################### ## Welcome to the permission setter 1.4 for MySQL. ## made by Luuk de Boer ###################################################################### What would you like to do: 1. Set password for an existing user. 2. Create a database + user privilege for that database and host combination (user can only do SELECT) 3. Create/append user privilege for an existing database and host combination (user can only do SELECT) 4. Create/append broader user privileges for an existing database and host combination (user can do SELECT,INSERT,UPDATE,DELETE) 5. Create/append quite extended user privileges for an existing database and host combination (user can do SELECT,INSERT,UPDATE,DELETE,CREATE,DROP,INDEX, LOCK TABLES,CREATE TEMPORARY TABLES) 6. Create/append full privileges for an existing database and host combination (user has FULL privilege) 7. Remove all privileges for for an existing database and host combination. (user will have all permission fields set to N) 0. exit this program
Předpokládáme, že chceme vytvořit účet adam, kterému chceme přidělit přístupová práva z lokálního stroje: možnost vytváření vlastních databází a manipulace s nimi, zvolíme tedy volbu 5; následuje dialog:
Make your choice [1,2,3,4,5,6,7,0]: 5 Which database from existing databases would you like to select: You can choose from: - information_schema - mysql - performance_schema - test Which database will it be (case sensitive). Type * for any: * OK, the user entry will NOT be limited to any database What username is to be created: adam Username = adam Would you like to set a password for petr [y/n]: y What password do you want to specify for adam: Type the password again: We now need to know from what host(s) the user will connect. Keep in mind that % means 'from any host' ... The host please: localhost Would you like to add another host [yes/no]: no Okay we keep it with this ... The following host(s) will be used: localhost. ###################################################################### That was it ... here is an overview of what you gave to me: The database name : * The username : adam The host(s) : localhost ###################################################################### Are you pretty sure you would like to implement this [yes/no]: yes Okay ... let's go then ... Everything is inserted and mysql privileges have been reloaded.
Nyní můžeme vyzkoušet, jak nový účet funguje; zalogování:
