Cassandra database installation
Last Updated: June 30, 2026

This section contains instructions for installing the Cassandra Database software on the servers designated to run as "[cassandra_seeds]" and "[cassandra_other]" in the ServAssure NXT Ansible Inventory file on the ServAssure NXT Platform.

NOTE: The software requirements assume that ServAssure NXT runs on dedicated hardware systems or virtual machines, as outlined in the Server and virtual machine requirements. Any deviation from the recommended requirements will require approval from CommScope before installation. If there are any concerns that need to be addressed, please contact CommScope Technical Support before starting this process.

Cassandra can attempt to stage and run temporary files in /tmp. If /tmp is already in use as a filesystem, or mounted using the noexec option, the Cassandra installation can fail with a message like /tmp filesystem mounted with noexec option. Please remount /tmp filesystem without the noexec option. To avoid installation failure and this message, before installing Cassandra remove the noexec flag from the partition where Cassandra will be installed.
