=== Description
|
|
|
|
When installing {es} with a DEB or RPM package, the current node is assumed to
|
|
be the first node in the cluster. {es} enables and configures security
|
|
features on the node, generates a password for the `elastic` superuser, and
|
|
configures TLS for the HTTP and transport layers.
|
|
|
|
Rather than form a single-node cluster, you can add a node to an existing
|
|
cluster where security features are already enabled and configured. Before
|
|
starting your new node, run the
|
|
<<create-enrollment-token,`elasticsearch-create-enrollment-token`>> tool
|
|
with the `-s node` option to generate an enrollment token on any node in your
|
|
existing cluster. On your new node, run the the
|
|
`elasticsearch-reconfigure-node` tool and pass the enrollment token as a
|
|
parameter.
|
|
|
|
NOTE: This tool is intended only for use on DEB or RPM distributions of {es}.
|
|
|
|
You must run this tool with `sudo` so that it can edit the necessary
|
|
files in your {es} installation configuration directory that are owned by
|
|
`root:elasticsearch`.
