This article shows you how to manage your Azure Database for MySQL Flexible Server instance deployed in Azure. Management tasks include compute and storage scaling, admin password reset, and viewing server details.

Prerequisites

If you don't have an Azure subscription, create an Azure free account before you begin. Currently, with an Azure free account, you can try Azure Database for MySQL - Flexible Server free for 12 months.

This article requires that you're running the Azure CLI version 2.0 or later locally. To see the version installed, run the az --version command. If you need to install or upgrade, see Install Azure CLI.

You'll need to log in to your account using the az login command. Note the id property, which refers to Subscription ID for your Azure account.

az login

Select the specific subscription under your account using az account set command. Make a note of the id value from the az login output to use as the value for subscription argument in the command. If you have multiple subscriptions, choose the appropriate subscription in which the resource should be billed. To get all your subscription, use az account list.

az account set --subscription <subscription id>
