Creating and Assigning Roles in MySQL

Managing access and granting privileges to individual users can be very time consuming and cumbersome. That is why MySQL provides the ability to create roles. Roles are granted privileges, then roles are assigned to users. The users inherit the privileges of the roles. In this lab, we'll create a set of roles and grant those roles specific privileges. Once the roles have been created, we'll assign them to the appropriate users, in order to grant access to databases and tables within the MySQL server.

  3. Challenge

    Grant Privileges to the `dev_all`, `dev_read`, and `dev_write` Roles According to the Information Provided in the Instructions

    This command will grant all privileges on the dev database to the dev_all role:

    mysql> GRANT ALL ON dev.* TO 'dev_all';

    To grant the SELECT privilege on the dev database to the dev_read role, run this:

    mysql> GRANT SELECT ON dev.* TO 'dev_read';

    Use the following command to grant the INSERT, UPDATE, AND DELETE privileges on the dev database to the dev_write role:

    mysql> GRANT INSERT, UPDATE, DELETE ON dev.* TO 'dev_write';

  4. Challenge

    Grant Privileges to the `prod_all`, `prod_read`, and `prod_write` Roles According to the Information Provided in the Instructions

    Use the following command to grant all privileges on the prod database to the prod_all role:

    mysql> GRANT ALL ON prod.* TO 'prod_all';

    Use the following command to grant the SELECT privilege on the dev database to the prod_read role:

    mysql> GRANT SELECT ON prod.* TO 'prod_read';

    Use the following command to grant the INSERT, UPDATE, AND DELETE privileges on the dev database to the prod_write role:

    mysql> GRANT INSERT, UPDATE, DELETE ON prod.* TO 'prod_write';

  5. Challenge

    Assign the Roles for the `dev` Database to the Appropriate Users According to the Information Provided in the Instructions

    mysql> GRANT dev_all to 'corey'@'localhost';

    Assign the dev_read role to the user will:

    mysql> GRANT dev_read to 'will'@'localhost';

    Assign the dev_write and dev_read roles to the user aaron:

    mysql> GRANT dev_write, dev_read to 'aaron'@'localhost';

    Set the default roles for the users so that the granted roles are active on login:

    mysql> SET DEFAULT ROLE ALL TO 'corey'@'localhost', 'will'@'localhost', 'aaron'@'localhost';

    Ensure that the user kenny does not have access to the dev database:

    mysql> select * from dev.products;

    Ensure that the user kenny has access to the prod database:

    mysql> select * from prod.products;

    Ensure that the user myles has read access to the prod database:

    mysql> select * from prod.products;

    Ensure that the user aaron has write access to the prod database:

    mysql> INSERT INTO prod.orders (orderID,userName,orderType,purchaseDate) VALUES (4,'mike','laptop','2018-04-08');
