Charmed MySQL tutorial

The Charmed MySQL Operator delivers automated operations management from day 0 to day 2 on the MySQL Community Edition relational database. It is an open source, end-to-end, production-ready data platform on top of Juju. As a first step this tutorial shows you how to get Charmed MySQL up and running, but the tutorial does not stop there. Through this tutorial you will learn a variety of operations, everything from adding replicas to advanced operations such as enabling Transport Layer Security (TLS). In this tutorial we will walk through how to:

• Set up your environment using LXD and Juju.
• Deploy MySQL using a single command.
• Access the admin database directly.
• Add high availability with MySQL InnoDB Cluster, Group Replication.
• Request and change the admin password.
• Automatically create MySQL users via Juju relations.
• Reconfigure TLS certificate in one command.

While this tutorial intends to guide and teach you as you deploy Charmed MySQL, it will be most beneficial if you already have a familiarity with:

• Basic terminal commands.
• MySQL concepts such as replication and users.
