This doesn't apply for auth-v2 as we improved data placement and removed cassandra quirk which was setting different CL for some default superuser involved operations. Fixes #18773 Closes scylladb/scylladb#18785

Enable Authentication
|
|
=====================
|
|
|
|
.. scylladb_include_flag:: upgrade-note-authentication.rst
|
|
|
|
Authentication is the process where login accounts and their passwords are verified, and the user is allowed access to the database. Authentication is done internally within Scylla and is not done with a third party. Users and passwords are created with roles using a ``CREATE ROLE`` statement. Refer to :doc:`Grant Authorization CQL Reference </operating-scylla/security/authorization>` for details.
|
|
|
|
The procedure described below enables Authentication on the Scylla servers. It is intended to be used when you do **not** have applications running with Scylla/Cassandra drivers.
|
|
|
|
.. warning:: Once you enable authentication, all clients (such as applications using Scylla/Apache Cassandra drivers) will **stop working** until they are updated or reconfigured to work with authentication.
|
|
|
|
If this downtime is not an option, you can follow the instructions in :doc:`Enable and Disable Authentication Without Downtime </operating-scylla/security/runtime-authentication>`, which using a transient state, allows clients to work with or without Authentication at the same time. In this state, you can update the clients (application using Scylla/Apache Cassandra drivers) one at the time. Once all the clients are using Authentication, you can enforce Authentication on all Scylla nodes as well.

|
Procedure
|
|
----------
|
|
|
|
#. For each Scylla node in the cluster, edit the ``/etc/scylla/scylla.yaml`` file to change the ``authenticator`` parameter from ``AllowAllAuthenticator`` to ``PasswordAuthenticator``.
|
|
|
|
.. code-block:: yaml
|
|
|
|
authenticator: PasswordAuthenticator
|
|
|
|
|
|
#. Restart Scylla.
|
|
|
|
.. include:: /rst_include/scylla-commands-restart-index.rst
|
|
|
|
#. Start cqlsh with the default superuser username and password.
|
|
|
|
.. code-block:: cql
|
|
|
|
cqlsh -u cassandra -p cassandra
|
|
|
|
.. note::
|
|
|
|
Before proceeding to the next step, we recommend creating a custom superuser
|
|
to improve security.
|
|
See :doc:`Creating a Custom Superuser </operating-scylla/security/create-superuser/>` for instructions.
|
|
|
|
#. If you want to create users and roles, continue to :doc:`Enable Authorization </operating-scylla/security/enable-authorization>`.
