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): 9042 (CQL) — restrict to your own IP where possible.
  3. Connect your client or application to the VM's IP on the database port, then create your application roles.
  4. Print the generated admin credential (see the support page) and change it after first sign-in.

Get your admin password (one time)

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/cassandra/admin-password

Sign in as admin (unless noted), then change the password immediately. The file is root-only and can be deleted once the password is stored securely.
