Run ScyllaDB and supporting services as a custom user:group

Topic: Planning and setup By default, ScyllaDB runs as user scylla in group scylla. The following procedure will allow you to use a custom user and group to run ScyllaDB.

1. Create the new user and update file permissions

.. code-block:: sh

useradd test groupadd test usermod test -G test chown -R test:test /var/lib/scylla

2. Edit /etc/sysconfig/scylla-server and change the USER and GROUP

.. code-block:: sh

USER=test GROUP=test

3. Edit /etc/systemd/system/multi-user.target.wants/scylla-server.service

.. code-block:: sh

User=test

4. Edit /etc/systemd/system/multi-user.target.wants/node-exporter.service

.. code-block:: sh

User=test Group=test

6. Reload the daemon settings and start ScyllaDB and node_exporter

.. code-block:: sh

systemctl daemon-reload systemctl start scylla-server systemctl start node-exporter

At this point, all services should be started as test:test user:

.. code-block:: sh

test 8760 1 11 14:42 ? 00:00:01 /usr/bin/scylla --log-to-syslog 1 --log-to-std ... test 13638 1 0 14:30 ? 00:00:00 /usr/bin/node_exporter --collector.interrupts
