Changing the default superuser
You can change the default superuser from the default cassandra user.
By default, each installation of Cassandra includes a superuser account named cassandra whose password is also cassandra. Superuser permissions allow creation and deletion of other users and the ability to grant or revoke permissions.
Note: Use the default cassandra user only to assist with
initial setup of new users and superusers, and then disable it.
- Logins for the cassandra user are performed with QUORUM consistency.
Do not use the default cassandra user in production, because QUORUM consistency has significant performance degradation for multiple datacenters.
- Logins for all other users are performed with LOCAL_ONE consistency. See Configuring consistency levels.
- Restrict rights of users as appropriate for security. For example, do not allow access to other keyspaces.
- Follow these steps to change the default superuser.
At installation, OpsCenter Lifecycle Manager prompts you to change the default superuser password.
