Create an Azure Database for MySQL - Flexible Server database in a VNet using Azure CLI

APPLIES TO: Azure Database for MySQL - Flexible Server

This sample CLI script creates an Azure Database for MySQL - Flexible Server in a VNet (private access connectivity method) and connects to the server from a VM within the VNet.

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.

# Follow steps in the parent article to test connectivity to the MySQL server from the VM

Test connectivity to the MySQL server from the VM

Use the following steps to test connectivity to the MySQL server from the VM by connecting using SSH, downloading MySQL tools, and then using them to connect to the MySQL server.

1. To SSH into the VM, start by getting the public IP address and then use MySQL tools to connect

   PUBLIC_IP=$(az vm list-ip-addresses --resource-group $RESOURCE_GROUP --name $VM --query "[].virtualMachine.network.publicIpAddresses[0].ipAddress" --output tsv)
   
   ssh azureuser@$PUBLIC_IP
   

2. Download MySQL tools and connect to the server. Substitute <server_name> and <admin_user> with your values.

   sudo apt-get update
   sudo apt-get install mysql-client
   
   wget --no-check-certificate https://dl.cacerts.digicert.com/DigiCertGlobalRootCA.crt.pem
   
   mysql -h <replace_with_server_name>.mysql.database.chinacloudapi.cn -u mysqladmin -p --ssl-mode=REQUIRED --ssl-ca=DigiCertGlobalRootCA.crt.pem
   

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 $RESOURCE_GROUP
