Deploying Azure Databases for MySQL server using Azure Portal

April 24, 2020 by

In this article, I am going to explain the step by step process to create an Azure Database for MySQL Server. Azure Database for MySQL is a fully-managed database as a service that uses MySQL community edition. It can manage the mission-critical workload with dynamic scalability. We can use it to develop various applications that leverage open-source tools and cross-platform applications. Let me explain these steps of a deployment process of MySQL Server on Azure.

How to create an Azure Database for MySQL Server

First, log in to the Azure portal using appropriate credentials. On the home screen, click on “More services.”

Azure portal dashboard

On All services screen, from the right pan, click on Databases. The list of database services offered by Azure will be displayed on the left pane. Choose Azure Database for MySQL servers. See the following image:

On Azure Database for MySQL servers screen, click on “Create Azure Database for MySQL Server.” See the following image:

Create new resource

On “Create MySQL Server,” choose the appropriate subscription from the “Subscription” drop-down box and choose the appropriate resource group from the “Resource group” drop-down box. If you haven’t created any resource group for MySQL, then you can create it by clicking on the “Create new” link. See the following image.

Choose subscription and resource group

Under the “Server Details” section, provide the following information:

  1. Server Name: Provide the desired server name. The server name must be unique, does not contain any special characters
  2. Location: You can choose the nearest location from your users or application server from the “Location” drop-down box
  3. Version: Choose the desired version of MySQL Server from the “Version” dialog box. Azure offers three versions of MySQL. The versions are 5.0,5.7 and 8.0
  4. Compute + storage: You can configure the number of virtual cores and the amount of storage that can be used to configure the MySQL. Default values are “4 vCores and 100GB storage” To change the configuration, click on “Configure server.” See the following image:

    Enter server details

On the pricing tier screen, you can increase or decrease the server resources according to your requirements. You can review the pricing details of the MySQL Server here. Following is the image of the Pricing tier screen.

Pricing tier

Change the server configuration parameters according to your requirement and click OK.

When you make the changes in the server configuration, changes reflect in compute + storage. Following is the image of the server details section:

Server details with changes

In the Administrator account section, provide the name of the administrator account and appropriate password to connect to that MySQL Server. Click on Review + Create.

Configure administrator account

On Review + create the screen, verify the configuration and settings, and click on “Create.”

Review and create

The deployment process of the MySQL Server will be started. The process might take a few minutes to complete. Once configuration completes. You can see “Your deployment is complete” screen. Click on the “Go to resource” button to view the configuration of MySQL Server.

Deployment is successful

On the resource page, you can view the details of the MySQL Server. See the following image:

View Azure database for MySQL Server configuration

Configure Firewall rules in Azure

Once MySQL Server deployed successfully, we must configure the firewall to allow the incoming connection to the database server. To do that, click on “Connection security” on the Azure Database for MySQL Server page. See the following image:

Connection security

On the “Connection security” page, you can add the specific IP Address or the range of IP Addresses of the computers that are allowed to connect to the Azure Database for MySQL Server. To add the IP Address of the computer that you are using to connect to MySQL Server, click on “Add current client IP Address” See the following image:

Configure firewall rule

Click on the Save button to save the firewall rule.

Connect to MySQL Server using MySQL workbench

Once the deployment completes, let us connect to the server. Open MySQL Workbench -> Click on MySQL connections -> Click on (+) sign. See the following image:

Welcome screen MySQL Workbench

On setup new connection dialog box, enter the desired name in Connection Name dialog box, choose appropriate connection method from connection method dialog box. Provide hostname, port number, and username to connect to the MySQL Server. Click on Test Connection. See the following image:

Setup new connection

When you click on the “Test connection” button, a prompt to enter the password opens. Enter the password and click OK.

Enter password

The connection has been established successfully.

Connection is established successfully

Once you are connected to the MySQL, in the schema menu of the MySQL workbench, you can see the list of databases created on the server.

View schemas

Connect to MySQL Server using the command-line tool

To connect the MySQL Server using the command line, first, you must download the MySQL command-line tool from here. Once you install the command-line tool, execute the following command to connect.

See the following image:

connect to MySQL using command line

Once connected, execute the following command to view the details of the MySQL Server.

Following is the output:

Following is the screenshot of command:

Restore a database to Azure MySQL Server from the local computer

Now, let us add a database by restoring the backup of a database. I have generated a backup of the “sakila” database on my workstation. You can generate the backup using the mysqldump command. Execute the following command:

Following is the image:

Generate the backup of sakila database

To restore the database on Azure Database for MySQL Server, create a database on MySQL Server. To do that, connect to the Azure Database for MySQL using MySQL workbench. Right-click on the schema menu and select on “Create Schema.

Create new schema

In the new_schema tab, enter the name of the schema, choose desired character set and collation from the “Charset/Collation” drop-down box and click on Apply. See the following image:

Create New schema

Alternatively, you can execute the following command to create a new schema.

Once the schema is created, execute the following command to import a backup from the local workstation.

When you restore the database using mysqldump, you might see the following error:

ERROR 1227 (42000): Access denied; you need (at least one of) the SUPER privilege(s) for this operation.

See the following image:

This error occurs when you are trying to import a file that contains “definers,” and it can be created or modified by superusers only. Azure Database for MySQL Server is a managed PaaS solution; therefore, SUPERUSER privileges are restricted; hence you cannot change the permissions.

To solve the error, perform the following step.

Replace the definers with the name of the user that is running the import process. For example, values of the definers,

Before:

DELIMITER ;;

/*!50003 CREATE*/ /*!50017 DEFINER=root@localhost*/ /*!50003…..*/;;

DELIMITER;;

After:

DELIMITER ;;

/*!50003 CREATE*/ /*!50017 DEFINER=MySQLAdmin@testmysqlazure*/ /*!50003…..*/;;

DELIMITER;;

After updating all the values in the import file, rerun the import process. The process should be completed successfully. Once the backup has been imported to a new database, you can view the schema, tables, and stored procedures in the “Schema navigator” menu.

Tables and Stored procedures in MySQL Workbench

Alternatively, you can see the list of databases by executing the following command from the MySQL command line.

See the following:

connect to mysql using command line

You can view the list of tables within the database by executing the following command.

See the following:

view tables
