# bootstrap-aggregator

## Description

Bootstrap the node as a Master Aggregator in the cluster.

When using this command, you should use `--memsql-id` rather than `--host` and/or `--port`.

This command also accepts `--license` as a convenience, which means you do not have to run [set-license](https://docs.singlestore.com/db/v9.1/reference/singlestore-tools-reference/sdb-admin-commands/set-license.md) beforehand.

To bootstrap a node, the node must have a valid license. Use the `--license` flag to specify a license to set before bootstrapping the node:

```shell
sdb-admin bootstrap-aggregator --memsql-id 0123ABCDEF --license BgEZY....==
```

If you previously set a license on the node, you can omit the `--license` flag:

```shell
sdb-admin bootstrap-aggregator --memsql-id 0123ABCDEF
```
