How To Install MySQL 8.0 on Debian 10 “Buster”

On today’s guide we will guide you on how to install and configure MySQL 8.0 on Debian 10 “Buster”. MySQL 8.0 is the current latest stable release of MySQL database server, one of the most used, popular, free open-source database server (FOSS) on the world. We will install MySQL 8.0 using the MySQL APT Repository which is available on MySQL website. It will provides deb packages for installing and managing MySQL server along with its MySQL client, and other components for Debian 10 codename Buster.

There are several features which have been added into the MySQL 8.0 database server like Data dictionary, Atomic data definition statements (Atomic DDL), Upgrade procedure, Session Reuse, Security and account management, Resource management, Table encryption management, as well as InnoDB enhancements.

Starting from MySQL 8.0, there is a data dictionary which incorporates a transactional data dictionary and it stores information about database objects. Where in the previous MySQL version, data dictionary was stored in metadata files and non-transactional tables. While the Atomic DDL statement combines some values like data dictionary updates, storage engine operations, and binary log writes associated with a DDL operation into a single atomic transaction.

Before going to the MySQL 8.0 installation proccedure, make sure to meet the following requirenments.
