Create an Azure Database for MySQL - Flexible Server instance and enable public access connectivity using Azure CLI

  • Article

APPLIES TO: Azure Database for MySQL - Flexible Server

This sample CLI script creates an Azure Database for MySQL - Flexible Server, configures a server-level firewall rule (public access connectivity method) and connects to the server after creation.

Once the script runs successfully, the MySQL Flexible Server will be accessible by all Azure services and the configured IP address, and you will be connected to the server in an interactive mode.

Note

The connectivity method cannot be changed after creating the server. For example, if you create server using Public access (allowed IP addresses), you cannot change to Private access (VNet Integration) after creation. To learn more about connectivity methods, see Networking concepts.

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

Prerequisites

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

Sign in to Azure

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 trail subscription, create a trial subscription before you begin.

az cloud set -n AzureChinaCloud
az login

subscription="<subscriptionId>" # add subscription here

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

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

Run the script

# Create an Azure Database for MySQL - Flexible Server Burstable B1ms instance
# and configure Public Access connectivity method

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="China East 2"
resourceGroup="msdocs-mysql-rg-$randomIdentifier"
tag="create-connect-burstable-server-public-access-mysql"
server="msdocs-mysql-server-$randomIdentifier"
login="azureuser"
password="Pa$$w0rD-$randomIdentifier"
ipAddress="None"
# Specifying an IP address of 0.0.0.0 allows public access from any resources
# deployed within Azure to access your server. Setting it to "None" sets the server 
# in public access mode but does not create a firewall rule.
# For your public IP address, https://whatismyipaddress.com

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
echo "Adding firewall for IP address range"
az mysql flexible-server firewall-rule create --name $server --resource-group $resourceGroup --rule-name AllowAzureIPs --start-ip-address 0.0.0.0 --end-ip-address 0.0.0.0

# Connect to server in interactive mode
az mysql flexible-server connect --name $server --admin-user $login --admin-password $password --interactive

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

Sample reference

This script uses the following commands. Each command in the table links to command specific documentation.

Command Notes
az group create Creates a resource group in which all resources are stored
az mysql flexible-server create Creates a Flexible Server that hosts the databases.
az mysql flexible-server firewall-rule create Creates a firewall rule to allow access to the Flexible Server and its databases from the entered IP address range.
az mysql flexible-server connect Connects to a Flexible Server to perform server or database operations.
az mysql flexible-server delete Deletes a Flexible Server.
az group delete Deletes a resource group including all nested resources.
