MySQL DBA Roadmap: Certification Preparation

Set Up a MySQL Server and Create Users

Install MySQL on your machine and create three users with different privilege levels.

Expected output: Three users created with appropriate privileges verified by SHOW GRANTS.

Hint: Use CREATE USER and GRANT statements to assign privileges.

Perform a Backup and Restore

Use mysqldump to back up a sample database and restore it to a new database instance.

Expected output: Database restored successfully with all data intact.

Hint: Use mysqldump for export and mysql command for import.

A MySQL DBA is responsible for installation, configuration, security management, backup and recovery, performance tuning, and ensuring high availability of MySQL databases.

Backups can be performed using tools like mysqldump for logical backups or MySQL Enterprise Backup for physical backups, depending on the requirements.

Proper user privilege management ensures database security by restricting access to authorized users and minimizing the risk of unauthorized data manipulation.
