Getting Started with Scylla on Red Hat Enterprise 7

Use these steps to install Scylla using Yum repositories on RHEL


  • Red Hat Enterprise Linux 7.2 or later, for the 64-bit x86_64 architecture
  • Yum package management application installed
  • ABRT conflict with Scylla coredump configuration. Remove it before installing Scylla: sudo yum remove -y abrt
  • Root or sudo access to the system. The Scylla packages create a scylla user. When starting Scylla as a service, the service runs as this user

For server configuration, see documentation on recommendations for high performance

Scylla is supported on Red Hat Enterprise Linux version 7.2 or later. There is no support for RHEL version 6.x and earlier


$ sudo yum install wget
$ sudo rpm -i
  • install a repo file: Add the Scylla RPM repo to your system, check the RPM content
  • install packages
$ sudo yum install scylla

Configure and run Scylla on RHEL

Configure Scylla

Configure the /etc/scylla/scylla.yaml file with the following parameters:

Item Content
cluster_name Name of the cluster, all the nodes in the cluster must have the same name
seeds Seed nodes are used during startup to bootstrap the gossip process and join the cluster
listen_address IP address that the Scylla use to connect to other Scylla nodes in the cluster
rpc_address IP address of interface for client connections (Thrift, CQL)

More information regard the scylla.yaml file

Scylla setup

Run the scylla_setup script to tune the system settings

sudo scylla_setup

This script invokes a set of scripts to configure several operating system settings, like setting RAID0 and XFS filesystem. It also 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 Scylla (see below). Scylla will not run without XFS or io.conf file. To bypass this check, set Scylla to developer mode

Run Scylla as a service (if not already running)

sudo systemctl start scylla-server

run nodetool

nodetool status

run cqlsh


Run cassandra-stress

cassandra-stress write -mode cql3 native <more options>


Scylla servers set up using this method have the system configuration covered on System Configuration Guide already applied, by scripts included with the RPM packages. See the guide for a complete reference on settings used
