![]() ![]() The new ALTER USER syntax supports this use case: mysql> CREATE USER IDENTIFIED WITH mysql_native_password In earlier versions, there was no way to change the authentication plugin for an existing user account without directly manipulating the er table (discouraged). Here’s a couple of important use cases the new syntax covers: Changing authentication plugin These attributes, and the syntax by which they are modified, is now consistent across CREATE USER and ALTER USER commands. Password/credentials or auth plugin mapping.These are consistent with CREATE USER – the same attributes which can be defined with a CREATE USER command can now be modified using an ALTER USER command. This all changes for the better in MySQL Server 5.7 – here’s how: Account attributes ![]() MySQL has a long history of confusing these – for example, requiring a GRANT command to set account resource limits or require SSL. With changes made in MySQL Server 5.7.6, a better distinction is made between privilege-level attributes (those which are managed via GRANT and REVOKE statements) and account-level attributes (those managed using CREATE USER and ALTER USER statements). Before MySQL Server 5.7.6, ALTER USER could only be used to expire a user’s password. ![]() To learn more about SingleStore DB User Management, click here.Complimenting the expanded CREATE USER syntax introduced in MySQL Server 5.7.6 is more useful ALTER USER syntax. | GRANT SELECT ON *.* TO /* via roles and groups */ | Validate Privileges using Show Grants mentioning the particular user as below, mysql> SHOW GRANTS FOR Grants for | If you haven't created the user yet, Create User as below, mysql> CREATE USER IDENTIFIED BY 'password' īelow command is used to Grant Group to a user, mysql> GRANT GROUP 'APP_CHECKERS' TO 'user_checker' Step 5: Granting the group to the specific user: Step 4: Assigning the role to the group using Grant Role: mysql> GRANT ROLE 'APP_CHECKER_ROLE' to 'APP_CHECKERS' Step 3: Now, we need to Create Group: mysql> CREATE GROUP 'APP_CHECKERS' Step 2: Granting the Role with desired privilege on required the DB's and tables: mysql> GRANT SELECT on *.* to ROLE 'APP_CHECKER_ROLE' Step 1: Create Role as below: mysql> CREATE ROLE 'APP_CHECKER_ROLE' Click here to learn more about RBAC (Role-Based Access Control). The following steps present an example for assigning a role to a user. In this way, it easier to remove or add users to a role by easily removing or adding a user to the group. In SingleStore, roles cannot be directly assigned to a user instead, users needed to be added to a group, and the role needed to be assigned to that group. Click here to learn about reasons why role-based access control is essential for database security. RBAC enables security teams to efficiently create, change, or discontinue roles as the unique needs of an organization evolve without having to endure the hardship of updating the privileges of individual users. Role-Based Access Control (RBAC) provides a methodology for regulating an individual user’s access to information systems or network resources based on their role in an organization. ![]()
