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.
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. Each Region contains multiple distinct locations called Availability Zones. You have the ability to choose which Region to host your Amazon RDS activity in.
b. In the Create database section, click 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.
d. You will now configure your DB instance.
Expand the dropdown below to see the example settings you can use for this tutorial:
- 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.
- DB instance class: Select db.t2.micro --- 1vCPU, 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.
e. You are now on the Connectivity section where you can provide additional information that RDS needs to launch the MariaDB DB instance. Expand the dropdown below to see the example settings for your DB instance.
Network & Security
- Virtual Private Cloud (VPC): Select Default VPC. For more information about VPC, see Amazon RDS and Amazon Virtual Private Cloud (VPC).
- 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 that you can directly connect to the database from your own device.
- VPC security groups: Select Create new 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.
- Availability zone: Choose No preference. See Regions and Availability Zones for more details.
- Port: Leave the default value of 3306.
In the Additional Configurations section:
- 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.
This option is not available in the free tier. For more information, see Encrypting Amazon RDS Resources.
- 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.
- 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.
- Auto minor version upgrade: Select Enable auto minor version upgrade to receive automatic updates when they become available.
- Maintenance window: Select No preference.
Clear Enable deletion protection for this tutorial. When this option is enabled, you're prevented from accidentally deleting the database.
Click Create database.
f. Your DB Instance is now being created. Click View Your DB Instance.
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.
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.
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.
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.
a. Launch the MySQL Workbench application and go to Database > Connect to Database (Ctrl+U) from the menu bar.
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.
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 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, then select Delete from the Actions dropdown menu.
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.
You have created, connected to, and deleted a MariaDB Database Instance with Amazon RDS. Amazon RDS makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while managing time-consuming database administration tasks, freeing you up to focus on your applications and business.
