MySql grant user permission

Question

I want to create a new user in MySql. I do not want that new user to do much with my existing databases [I just want to grant Select privilege to him], but he can do anythin

Answer 1

To provide a specific user with a permission, you can use this framework:

GRANT [type of permission] ON [database name].[table name] TO ‘[username]’@'localhost’; 
GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost';

The asterisks in this command refer to the database and table (respectively) that they can access—this specific command allows to the user to read, edit, execute and perform all tasks across all the databases and tables.

Once you have finalized the permissions that you want to set up for your new users, always be sure to reload all the privileges.

 FLUSH PRIVILEGES;
