Create and Connect to a MariaDB Database

with Amazon RDS

Introduction

In this tutorial, you will learn how to create an environment to run your MariaDB database (we call this environment an instance), connect to the database, and delete the DB instance. We will do this using Amazon Relational Database Service (Amazon RDS) and everything done in this tutorial is Free Tier eligible.

Implementation

  • Enter the RDS Console

    When you click here, the AWS management console will open in a new browser window, so you can keep this step-by-step guide open. When this screen loads, find RDS under Database and click to open the Amazon RDS Console.

    AWS Management Console
  • Create a MariaDB Instance

    In this step, we will use Amazon RDS to create a MariaDB instance with a db.t2.micro DB instance class, 20 GB of storage, and automated backups enabled with a retention period of one day.  As a reminder, all of this is free tier eligible.

    a. In the top right corner of the Amazon RDS console, select the Region in which you want to create the DB instance.

    Note: AWS Cloud resources are housed in highly available data center facilities in different areas of the world. You have the ability to choose which Region to host your Amazon RDS activity in. 

    In the top right corner of the Amazon RDS console, select the Region in which you want to create the DB instance.

    b.   In the Create database section, choose Create database.

    In the Create database section, choose Create database.

    c.  You now have options to select your engine. For this tutorial, choose the MariaDB icon, select the default DB engine version, and choose the Free Tier template.

    Select PostgreSQL engine

    d. You will now configure your DB instance. 

    The list below shows the example settings that you can use for this tutorial:

    Settings:

    • DB instance identifier: Type a name for the DB instance that is unique for your account in the Region you selected. For this tutorial, enter myrdstest.
    • Master username: Type a username that you will use to log in to your DB instance. We will use masterUsername in this example.
    • Master password: Type a password that contains from 8 to 41 printable ASCII characters (excluding /,", and @) for your master user password.
    • Confirm password: Retype your password.
    Settings View

    Instance specifications:

    • DB instance class: Select the default, db.t2.micro --- 1 vCPU, 1 GIB RAM. This equates to 1 GB memory and 1 vCPU. To see a list of supported instance classes, see Amazon RDS Pricing.
    • Storage type: Select General Purpose (SSD). For more information about storage, see Storage for Amazon RDS.
    • Allocated storage: Select the default of 20 to allocate 20 GB of storage for your database. You can scale up to a maximum of 64 TB with Amazon RDS for MariaDB.
    • Enable storage autoscaling: If your workload is cyclical or unpredictable, you would enable storage autoscaling to enable RDS to automatically scale up your storage when needed. This option does not apply to this tutorial.
    • Multi-AZ deployment: This option does not apply to this tutorial. Using a Multi-AZ Deployment will automatically provision and maintain a synchronous standby replica in a different Availability Zone. Note that you will have to pay for Multi-AZ Deployment. For more information, see High Availability Deployment
    Settings View

    e. You are now on the Connectivity section where you provide additional information that RDS needs to launch your MariaDB DB instance. The list below shows settings for our example DB instance.

    Network & Security

    Additional connectivity configurations

    • Subnet group: Choose the default subnet group. For more information about subnet groups, see Working with DB Subnet Groups.
    • Public accessibility: Choose Yes. This will allocate an IP address for your database instance so you can directly connect to the database from your own device.
    • Availability zone: Choose No preference. See Regions and Availability Zones for more details.
    • VPC security groups: Select Create new VPC security group. This will create a security group that will allow connection from the IP address of the device that you are currently using to the database created.
    • Port: Leave the default value of 3306.
    Settings View

    In the Additional Configurations section:

    Database options

    • Database name: Type a database name that is 1 to 64 alpha-numeric characters. If you do not provide a name, Amazon RDS will not automatically create a database on the DB instance you are creating.
    • DB parameter group: Leave the default value. For more information, see Working with DB Parameter Groups.
    • Option group: Leave the default value. Amazon RDS uses option groups to enable and configure additional features. For more information, see Working with Option Groups.

    Encryption
    This option is not available in the Free Tier. For more information, see Encrypting Amazon RDS Resources

    Backup

    • Backup retention period: You can choose the number of days to retain the backup you take. For this tutorial, set this value to 1 day.
    • Backup window: Use the default of No preference.

    Monitoring

    • Disable enhanced monitoring: Use the default to stay within the free tier. Enabling enhanced monitoring will give you metrics in real time for the operating system (OS) that your DB instance runs on. For more information, see Viewing DB Instance Metrics.
    Settings View

    Maintenance

    • Auto minor version upgrade: Select Enable auto minor version upgrade to receive automatic updates when they become available.
    • Maintenance Window: Select No preference.

    Deletion protection
    Clear Enable deletion protection for this tutorial. When this option is enabled, you can't delete the database.

    Click Create database.

    Settings View

    f. Your DB Instance is now being created.  Click View Your DB Instances.

    Click Instances to track the status of your DB instance launch. When the status changes from creating to available, the DB instance is ready for usage.

    Note: It can take several minutes for the new DB instance to become available. Feel free to move on to the next step as you wait.

    Your DB Instance is now being created.  Click View Your DB Instances
  • Download a SQL Client

    After the database instance creation is complete and the status changes to available, you can connect to a database on the DB instance using any standard SQL client. As MariaDB is compatible with MySQL, we will download MySQL Workbench, a popular MySQL client.

    a. Go to the Download MySQL Workbench website to download and install MySQL Workbench. For more information on using MySQL, see the MySQL Documentation

    Note:  Remember to use MySQL Workbench from the same device from which you created the DB Instance. The security group your database is placed in is configured to allow connection only from the device from which you created the DB instance.

    Download SQL Workbench

    b. You will be prompted to login, sign up, or begin your download.  You can click No thanks, just start my download for a quick download.

    MySQL Download
  • Connect to the MariaDB Instance

    In this step, we will connect to the database that you created using MySQL Workbench.

    a. Launch the MySQL Workbench application and go to Database > Connect to Database (Ctrl+U) from the menu bar.

    MySQL Workbench application

    b. A dialog box appears.  Enter the following:

    • Hostname: You can find your hostname on the Amazon RDS console as shown in the screenshot to the right.  Enter or paste the hostname of the DB Instance running the MariaDB database engine. For example, the hostname name could be: myrdstest.cg034hpkmmjt.us-east-1.rds.amazonaws.com.
    • Port: The default value should be 3306.
    • Username: Type in the username you created for the Amazon RDS database.  Our example was 'masterUsername.'
    • Password: Click Store in Vault and enter the password that you used when creating the Amazon RDS database.

    Click OK

    Dialog box

    c. You are now connected to the database. On the MySQL Workbench, you will see various schema objects available in the database. Now you can start creating tables, insert data, and run queries.

    You are now connected to the database
  • Delete the DB Instance

    You can easily delete the MariaDB DB Instance from the Amazon RDS console. It is a best practice to delete instances that you are no longer using so that you don’t keep getting charged for them.

    a. Go back to your Amazon RDS Console.  Select Databases, choose the instance that you want to delete, and then select Delete from the Actions dropdown menu.

    Select Delete under Actions

    b. You are asked to create a final snapshot and to confirm the deletion. For our example, do not create a final snapshot, acknowledge that you want to delete the instance, and then click Delete

    Note: Deleting your DB Instance may take a few minutes
