Cloudwrxs - MariaDB on Microsoft Windows Server 2025

Prerequisite: IAM Role Requirement (Before Launching the Instance) Before launching the EC2 instance from this AMI, you must ensure that an IAM Role with AWS Secrets Manager permissions is attached. During first boot, the MariaDB root password is: a. Automatically generated b. Securely stored in AWS Secrets Manager If the instance does not have proper IAM permissions, the password will not be stored.

Option 1: Use Existing Role with SecretsManagerReadWrite (Quick Setup) If you already have an IAM role with the AWS managed policy: SecretsManagerReadWrite You may attach that role to the EC2 instance during launch.

Option 2: Recommended (Least Privilege Policy) Step 1: Create Custom IAM Policy Go to: IAM, Policies, Create Policy, JSON Paste: { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "secretsmanager:CreateSecret", "secretsmanager:PutSecretValue", "secretsmanager:DescribeSecret" ], "Resource": "arn:aws:secretsmanager:<region>:<account-id>:secret:/awsmarketplace/mariadb/*" } ] } Save the policy.

Step 2: Create IAM Role for EC2

1. Go to IAM, Roles, Create Role 2.Select AWS Service
2. Choose EC2
3. Attach: a. The custom policy you created b. (Recommended) AmazonSSMManagedInstanceCore
4. Name the role (example: MariaDBSecretsRole)
5. Create the role

Step 3: Attach Role During EC2 Launch When launching the instance from the AMI:

1. Go to Advanced Details

2. Under IAM Instance Profile

3. Select the IAM role you created

4. Launch the instance

5. Launch EC2 Instance from AMI Create Instance from AMI. Retrieve the Windows password from the AWS EC2 console:

6. Select your instance

7. Click Connect

8. Choose RDP Client

9. Click Get Windows Password

10. Upload your EC2 key pair to decrypt

11. Retrieve the Administrator password

12. Connect to the Instance via RDP Use Remote Desktop Connection (mstsc) on your Windows or Mac machine. In the Computer field, enter:

    <your-ec2-public-ip>

Log in using: Username: Administrator Password: Retrieved from AWS EC2 console

3. Retrieve MariaDB Root Password (Required) The MariaDB root password is automatically generated during first boot and securely stored in AWS Secrets Manager. The installation-time password is NOT valid.

To Retrieve the Password: a. Go to AWS Console b. Open AWS Secrets Manager c. Locate the secret: /awsmarketplace/mariadb/<instance-id> d. Click Retrieve secret value e. Copy the password field

Example: { "username": "root", "password": "AutoGeneratedSecurePassword", "engine": "mariadb", "host": "localhost", "port": 3306 }

4. Verify MariaDB Installation After connecting via RDP: Check MariaDB Version Open PowerShell: "C:\Program Files\MariaDB 11.4\bin\mysql.exe" --version (Adjust path if version differs.)

Connect Using MariaDB Command Line Open PowerShell: "C:\Program Files\MariaDB 11.4\bin\mysql.exe" -u root -p Enter the password retrieved from AWS Secrets Manager when prompted.

Connect Using GUI Client (Optional) You may use: MariaDB Client MySQL Workbench (compatible) DBeaver

Connection settings: Host: localhost Port: 3306 Username: root Password: Retrieved from AWS Secrets Manager

5. Changing the MariaDB Root Password (Optional) If you change the password manually: a. Open PowerShell as Administrator b. Connect: "C:\Program Files\MariaDB 11.4\bin\mysql.exe" -u root -p c. Run: ALTER USER 'root'@'localhost' IDENTIFIED BY 'NewStrongPasswordHere'; FLUSH PRIVILEGES; d. Exit: exit;

If you change the password manually, update the value in AWS Secrets Manager to keep it synchronized.
