This section describes how to use the cbcluster command as a non-root user. cbcluster is a command line utility that you can use to manage and configure Carbon Black EDR clusters on the primary node.

cbcluster supports the following options:

  • cbcluster start

  • cbcluster stop

  • cbcluster status

  • cbcluster add-node

These commands run in root context and require users to have sudo privileges to invoke /usr/share/cb/cbcluster on the primary node. Additionally, the cbclusteradd-node command, which is used to add a new minion node to a cluster, connects and remotely executes on the minion a series of commands for cluster configuration.

Note:

  • Make sure that the primary and minion nodes are running the same version of Carbon Black EDR prior to running the cbcluster add-node command. If the versions are not the same, an error message displays.

  • The cbcluster reshard command is deprecated.

Starting with Carbon Black EDR version 5.1.1, you can define a non-root user as the remote user for minion communication and execution. Previously, when adding a minion node to a cluster, the cbcluster utility required availability of root user on the minion node. In Carbon Black EDR version 5.1.1 and later releases, this requirement is relaxed, and minion nodes can be configured as a non-root user.
