add-aggregator

Description

Add the node as a child aggregator to the cluster.

This command will add the specified node as a child aggregator and must be run on the Master Aggregator.

A cluster node can be specified by using the --memsql-id flag. The command will find the host and port of the specified node and provide those as arguments to the Master Aggregator.

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

The --password flag is required and specifies the SingleStoreroot password. You can use this flag in conjunction with the --user flag to specify a SingleStore user that is different from the root user and the user’s password.

Note that the MEMSQL_PASSWORD environment variable is a safer, alternative option for setting the password.

Wrap the password in single quotes (') to avoid having special characters included in the password interpreted by the shell. For example: sdb-admin add-aggregator --host memsql-01 --port 3306 --password '<<fooismypassword'

Examples

Shell

sdb-admin add-aggregator --memsql-id 0123ABCDEF

Shell

sdb-admin add-aggregator --host memsql-01 --port 3306

Usage

Usage:
  sdb-admin add-aggregator [flags]

  For flags that can accept multiple values (indicated by VALUES after the name of the flag),
  separate each value with a comma.

Flags:
  -h, --help                 Help for add-aggregator
      --host string          The cluster-addressable hostname for the aggregator
      --memsql-id MemsqlID   The node ID of the node to be added as an aggregator
  -p, --password STRING      The database user's password. If a password is specified on the command line, it must not contain an unescaped '$' character as it will be replaced by the shell.
                             If a password is not specified on the command line, Toolbox will attempt to read the password from the ‘MEMSQL_PASSWORD’ environment variable.
                             If this variable is present but does not contain a value, or if the variable does not exist, Toolbox will prompt for a password
      --port PORT            The cluster-addressable port for the aggregator
      --skip-validate-env    Skip environment validation
      --user string          The database user (default "root")

Global Flags:
      --backup-cache FILE_PATH                File path for the backup cache
      --cache-file FILE_PATH                  File path for the Toolbox node cache
  -c, --config FILE_PATH                      File path for the Toolbox configuration
      --disable-colors                        Disable color output in console, which some terminal sessions/environments may have difficulty with
      --disable-spinner                       Disable the progress spinner, which some terminal sessions/environments may have issues with
  -j, --json                                  Enable JSON output
      --parallelism POSITIVE_INTEGER          Maximum number of operations to run in parallel
      --runtime-dir DIRECTORY_PATH            Where to store Toolbox runtime data
      --ssh-control-persist SECONDS           Enable SSH ControlPersist and set it to the specified duration in seconds
      --ssh-max-sessions POSITIVE_INTEGER     Maximum number of SSH sessions to open per host, must be at least 3
      --ssh-strict-host-key-checking          Enable strict host key checking for SSH connections
      --ssh-user-known-hosts-file FILE_PATH   Path to the user known_hosts file for SSH connections. If not set, /dev/null will be used
      --state-file FILE_PATH                  Toolbox state file path
  -v, --verbosity count                       Increase logging verbosity: valid values are 1, 2, 3. Usage -v=count or --verbosity=count
  -y, --yes                                   Enable non-interactive mode and assume the user would like to move forward with the proposed actions by default
