Configure active geo-replication for a single database in Azure SQL Database using the Azure CLI

Applies to: Azure SQL Database

This Azure CLI script example configures active geo-replication for a single database and fails it over to a secondary replica of the database.

If you don't have an Azure subscription, create an Azure free account before you begin.

Prerequisites

• Use the Bash environment in Azure Cloud Shell. For more information, see Quickstart for Bash in Azure Cloud Shell.

  

• If you prefer to run CLI reference commands locally, install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.

  • If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For other sign-in options, see Sign in with the Azure CLI.

  • When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.

  • Run az version to find the version and dependent libraries that are installed. To upgrade to the latest version, run az upgrade.

Sample script

Launch Azure Cloud Shell

The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.

To open the Cloud Shell, select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to https://shell.azure.com.

When Cloud Shell opens, verify that Bash is selected for your environment. Subsequent sessions will use Azure CLI in a Bash environment. Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press Enter to run it.

Sign in to Azure

Cloud Shell is automatically authenticated under the initial account signed-in with. Use the following script to sign in using a different subscription, replacing <Subscription ID> with your Azure Subscription ID. If you don't have an Azure subscription, create an Azure free account before you begin.

subscription="<subscriptionId>" # add subscription here

az account set -s $subscription # ...or use 'az login'

For more information, see set active subscription or log in interactively

Run the script

# Configure active geo-replication for a single database in Azure SQL Database

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
resourceGroup="msdocs-azuresql-rg-$randomIdentifier"
tag="setup-geodr-and-failover-single-database"
server="msdocs-azuresql-server-$randomIdentifier"
database="msdocsazuresqldb$randomIdentifier"
login="azureuser"
password="Pa$$w0rD-$randomIdentifier"

failoverResourceGroup="msdocs-azuresql-failover-rg-$randomIdentifier"
failoverLocation="Central US"
secondaryServer="msdocs-azuresql-secondary-server-$randomIdentifier"

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

echo "Creating $resourceGroup in $location and $failoverResourceGroup in $failoverLocation..."
az group create --name $resourceGroup --location "$location" --tags $tag
az group create --name $failoverResourceGroup --location "$failoverLocation"

echo "Creating $server in $location and $secondaryServer in $failoverLocation..."
az sql server create --name $server --resource-group $resourceGroup --location "$location" --admin-user $login --admin-password $password
az sql server create --name $secondaryServer --resource-group $failoverResourceGroup --location "$failoverLocation" --admin-user $login --admin-password $password

echo "Creating $database on $server..."
az sql db create --name $database --resource-group $resourceGroup --server $server --service-objective S0

echo "Establishing geo-replication on $database..."
az sql db replica create --name $database --partner-server $secondaryServer --resource-group $resourceGroup --server $server --partner-resource-group $failoverResourceGroup
az sql db replica list-links --name $database --resource-group $resourceGroup --server $server

echo "Initiating failover..."
az sql db replica set-primary --name $database --resource-group $failoverResourceGroup --server $secondaryServer

echo "Monitoring health of $database..."
az sql db replica list-links --name $database --resource-group $failoverResourceGroup --server $secondaryServer

echo "Removing replication link after failover..."
az sql db replica delete-link --resource-group $failoverResourceGroup --server $secondaryServer --name $database --partner-server $server --yes

Clean up resources

Use the following command to remove the resource group and all resources associated with it using the az group delete command - unless you have an ongoing need for these resources. Some of these resources may take a while to create, as well as to delete.

az group delete --name $resourceGroup
