Quick start

  1. Deploy from the Azure Marketplace (Get It Now → Create), choosing your SSH key at the Administration step.
  2. Allow inbound SSH (22) for yourself plus the application port(s): 3306 (MySQL protocol) — to your application subnets only — restrict to your own IP where possible. The in-image firewall already allows them; only the Network Security Group (NSG) keeps them closed.
  3. Connect locally with `mariadb -u root -p` using the generated password (see First login below), create your application user and schema.
  4. Remote clients: MariaDB listens on all interfaces; firewalld already allows 3306, so scope the NSG rule tightly.

First login / credentials

This image generates its admin credential on the VM at first boot — nothing is pre-set. SSH into the VM with the username + key you chose at deploy, then print the generated credential:

ssh <your-username>@<VM-IP>
sudo cat /var/lib/mysql/.root-password

Sign in as root (root@localhost, password set at first boot).

  1. Print the generated root password from the file (first boot sets it with ALTER USER and removes anonymous users and the test database).
  2. Connect locally: mariadb -u root -p.
  3. Create your application user and schema, change the root password, and delete the file.

The MariaDB root password is generated at first boot and stored root/mysql-readable in /var/lib/mysql/.root-password. Change it after first sign-in.
