Create and Configure an Aurora MySQL Database Cluster

In this hands-on lab, we will create an Aurora MySQL database cluster. First, we will verify that the security groups and network ACLs (NACLs)s are all configured correctly, then create a new security group, and finally create an Aurora MySQL database in a private subnet.

  1. Challenge

    Verify the Security Groups and NACLs

    Verify the private subnets are associated with a route table that does not contain a direct route to an internet gateway. Verify NACLs allow TCP traffic on ports 0-65535.

  2. Challenge

    Create an Aurora MySQL Database Security Group

    Create a new database security group allowing MySQL/Aurora access on port 3306 from the default security group. Then update the default security group rules to allow SSH port 22 traffic from anywhere.

  3. Challenge

    Create an Aurora MySQL Database Cluster

    1. Create a RDS Aurora database, ensuring the database is launched in a private subnet.
    2. Ensure the subnet group (create new) and security group associated with the RDS Aurora database permits traffic on TCP 3306:
    3. Create an Aurora Database
    4. Select the default MySQL and default MySQL version

    8. Add password for the admin credentials
    9. For the DB instance size choose burstable and db.t2.small
    10. Enable multi-AZ deployment
    11. Select or create new subnet group
    12. Choose to not have your database publicly accessible
    13. Choose a security group
    14. Leave the defaults for AZ and database port
    15. Add auroraclusterinstance1 as the DB instance identifier
    16. Add initial database name: auroradb
    17. Leave the defaults for parameter groups
    18. Leave defaults for IAM, Failover, Backup, Encryption, BackTrack
    19. Do not enable enhanced monitoring because it will take a bit longer for your database to create
