Easy way to migrate an existing PHP site with MySQL to Azure App Service.

March 15, 2023

In this blog, we will cover the easy way to migrate an existing PHP site with MySQL to Azure App Service.

In case you do not have an existing App Service and Azure Database for MySQL setup, you can follow this blog: Tutorial: PHP app with MySQL - Azure App Service | Microsoft Learn.

This setup will create a VNET and MySQL database where the MySQL access will be locked down and not exposed to the public internet, which is compliant with recommended best practices for security.

To migrate your PHP code to Azure App Service, we can use one of the deployment methods such as Zip Deploy: Run your app from a ZIP package - Azure App Service | Microsoft Learn

During the deployment to install any application dependencies like composer packages add an app setting, SCM_DO_BUILD_DURING_DEPLOYMENT, and setting it to 1.

The easiest way to get to the Kudu console would be to go directly to http://yoursitename.scm.azurewebsites.net/newui (replace "yoursitename" with your actual Web App name) through the browser. You can also launch the Kudu console from the Azure portal:

Select "File Manager" and drag or upload the "dump.sql" file to the /home/site directory and the certificate needed to communicate over SSL, which you can get from the Azure Portal.

Select "WebSSH" and go to /home/site, run the below command to import the sql dump after replacing Username, Password, Hostname, port (which is 3306 by default), and destination database name:
mysql -h Hostname -u Username -p --ssl-ca=/home/site/DigiCertGlobalRootCA.crt.pem destination_database_name < dump.sql

This should populate all your data from "dump.sql" into the Azure MySQL - Flexible MySQL database over a secure connection.

To establish a secure connection to Azure Database for MySQL over SSL from your application, refer to the following code samples: Configure SSL - Azure Database for MySQL | Microsoft Learn

$databases['default']['default'] = array (

'database' => 'quickstartdb',

'username' => ‘myadmin@mydemoserver,

'password' => ‘yourpassword',

'prefix' => '',

'host' => 'mydemoserver.mysql.database.azure.com ',

'port' => '3306',

'namespace' => 'Drupal\\mysql\\Driver\\Database\\mysql',

'driver' => 'mysql',

'autoload' => 'core/modules/mysql/src/Driver/Database/mysql/',

'pdo' => [

\PDO::MYSQL_ATTR_SSL_CA =>'/home/site/DigiCertGlobalRootCA.crt.pem',

\PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT => false

],

);
