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

APPLIES TO: Azure Database for MySQL - Flexible Server

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


When you Stop the server it remains in that state for the next 30 days in a stretch. If you do not manually Start it during this time, the server will automatically be started at the end of 30 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.

# Create a server, perform restart / start / stop operations

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
# Specifying an IP address of allows public access from any resources
# deployed within Azure to access your server. Setting it to "None" sets the server

echo "Using resource group $resourceGroup with login: $login, password: $password..."

# Create a resource group
echo "Creating $resourceGroup in $location..."
az group create --name $resourceGroup --location "$location" --tags $tag

# Create a MySQL Flexible Server in the resource group
echo "Creating $server"
az mysql flexible-server create --name $server --resource-group $resourceGroup --location "$location" --admin-user $login --admin-password $password --public-access $ipAddress

# Optional: Add firewall rule to connect from all Azure services
# To limit to a specific IP address or address range, change start-ip-address and end-ip-address
