add-leaf

Add a leaf node to the MemSQL cluster.

Usage

Usage:
  memsqlctl add-leaf [flags]

Flags:
      --availability-group int     the availability group to assign the node
  -h, --help                       help for add-leaf
      --host string                the cluster-addressable hostname for the node
  -p, --password REQUIRED_STRING   the SQL password for connecting to MemSQL
      --port PORT                  the cluster-addressable port for the node (default 3306)
      --user string                the SQL user for connecting to MemSQL (default "root")

Global Flags:
  -c, --config FILE_PATH                     Path to the memsqctl config file
      --default-install-dir DIRECTORY_PATH   Path to the default install directory
  -j, --json                                 Print output in JSON format
      --node-metadata-file FILE_PATH         Path to the node metadata file
      --parallelism int                      Maximum amount of operations to be run in parallel
      --ssl-ca FILE_PATH                     Path to the CA certificate file in PEM format to authenticate the MemSQL server certificate
      --timeout duration                     Maximum time for operation to complete (e.g., 30s, 10m, 1.5h)
  -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 must be run from the same host that the master aggregator is currently running on.

If --availability-group is specified, memsqlctl will verify via the master aggregator that high availability is enabled. It will then run the query ADD LEAF user:password@host:port [INTO GROUP {1|2}] on the master aggregator.

This command is interactive unless you use either the --yes or --json flags to override interactive behavior.

Output

The following is the standard output for the add-leaf command.

$ sudo memsqlctl add-leaf --host "172.17.0.8"
memsqlctl will perform the following actions on the local master aggregator on port 3306:
  · Run `ADD LEAF root:****@172.17.0.8:3306 INTO GROUP 1`
