Configure and Run ScyllaDB

#. Configure the following parameters in the /etc/scylla/scylla.yaml configuration file.

cluster_name - The name of the cluster. All the nodes in the cluster must have the same cluster name configured.
seeds - The IP address of the first node. Other nodes will use it as the first contact point to discover the cluster topology when joining the cluster.
listen_address - The IP address that ScyllaDB uses to connect to other nodes in the cluster.
rpc_address - The IP address of the interface for CQL client connections.

#. Run the scylla_setup script to tune the system settings and determine the optimal configuration.

.. code-block:: console

  sudo scylla_setup

The script invokes a set of :ref:scripts to configure several operating system settings; for example, it sets RAID0 and XFS filesystem.
The script runs a short (up to a few minutes) benchmark on your storage and generates the /etc/scylla.d/io.conf configuration file. When the file is ready, you can start ScyllaDB. ScyllaDB will not run without XFS or io.conf file.
You can bypass this check by running ScyllaDB in :doc:developer mode </getting-started/installation-common/dev-mod>. We recommend against enabling developer mode in production environments to ensure ScyllaDB's maximum performance.

#. Run ScyllaDB as a service (if not already running).

.. code-block:: console

  sudo systemctl start scylla-server

Now you can start using ScyllaDB. Here are some tools you may find useful.

Run nodetool:

.. code-block:: console

 nodetool status

Run cqlsh:

.. code-block:: console
