Restart/stop/start an Azure Database for MySQL - Flexible Server using Azure CLI

This sample CLI script performs restart, start and stop operations on an Azure Database for MySQL - Flexible Server.

If you don't have an Azure subscription, create an Azure free account before you begin. With an Azure free account, you can now try Azure Database for MySQL - Flexible Server for free for 12 months. For more details, see Try Flexible Server for free.

Important

When you Stop the server it remains in that state for the next 7 days in a stretch. If you do not manually Start it during this time, the server will automatically be started at the end of 7 days. You can chose to Stop it again if you are not using the server.

During the time server is stopped, no management operations can be performed on the server. In order to change any configuration settings on the server, you will need to start the server.

Also, see stop/start limitations before performing stop/start operations.
