# bootstrap-aggregator

## Description

Bootstrap a Master Aggregator node on the host by promoting a node to Master Aggregator.

This command must be run from the same host that the node is on.

If `--memsql-id` is not specified, `memsqlctl` will check if there is only one “untyped” node on the local host. and if so, choose that node to be bootstrapped.

## Usage

```
Usage:
  memsqlctl bootstrap-aggregator [flags]

Flags:
  -h, --help               Help for bootstrap-aggregator
      --host string        The cluster-addressable hostname of the local host
      --license LICENSE    The license to apply to the node before bootstrapping
      --memsql-id string   The node ID

Global Flags:
  -c, --config FILE_PATH                     Path to the memsqctl config file
      --default-install-dir DIRECTORY_PATH   Path to the default install directory
      --insecure-ssl                         Fall back to insecure SSL connections to local nodes if memsqlctl is unable to otherwise establish a connection (ADVANCED)
  -j, --json                                 Print output in JSON format
      --node-metadata-file FILE_PATH         Path to the node metadata file
      --parallelism POSITIVE_INTEGER         Maximum amount of operations to be run in parallel
      --ssl-ca FILE_PATH                     The path to the CA certificate file (in PEM format) to authenticate the database certificate
      --timeout duration                     Maximum time for operation to complete (e.g., 30s, 10m, 1.5h)
      --verbose-json                         Print output in JSON format, include some warnings and user messages
  -v, --verbosity count                      Increase logging verbosity
  -y, --yes                                  Enable non-interactive mode and assume the user would like to move forward with the proposed actions by default
```

## Remarks

* This command is interactive unless you use either `--yes` or `--json` flag to override interactive behavior.
* The `memsqlctl bootstrap-aggregator` command is equivalent to the [sdb-admin bootstrap-aggregator](https://docs.singlestore.com/db/v9.1/reference/singlestore-tools-reference/sdb-admin-commands/bootstrap-aggregator.md) command.

## Output

The following is the standard output for the `bootstrap-aggregator` command.

```shell
sudo memsqlctl bootstrap-aggregator --host "172.17.0.2" --license <license>

```

```output

memsqlctl will perform the following actions on the local node on port 3306:
  · Run `BOOTSTRAP AGGREGATOR 172.17.0.2`

Would you like to continue? [y/N]: y
✓ Bootstrapped node with MemSQL ID 179062CAEEBCBDA755B75297BF6D9B2AE4C98FB7
