change-root-password

Info

MemSQL Helios does not support this command.

Change the MemSQL root password for a MemSQL node on a host.

Usage

Change the root password for a node on a host.
The root password is stored in the following places:
- In a cluster metadata, which is used by a cluster to verify incoming connections
- In the "nodeMetadataFile" on each host (run "memsqlctl env" to display the path to the file) , which is used by Toolbox to connect to a node

The "change-root-password" command can be used in the following cases:
- If the "nodeMetadataFile" is in sync with the cluster metadata, the command will update the password in both the cluster metadata and the "nodeMetadataFile" by calling 'SET PASSWORD FOR 'root'@<host> = PASSWORD(<new password>)'
- If the "nodeMetadataFile" is no longer in sync with the cluster and the nodes have become inaccessible (such as when the password is changed without using Toolbox), the command will update the password only in "nodeMetadataFile" file and only if the provided password matches the password in the cluster metadata

Toolbox encrypts passwords when sending data to a remote host. If the encryption key is broken on a remote host, it must be fixed with the following command:

memsql-admin change-root-password --fix-secure-key --ctl-host <host>

After running this command, the user must also set the root password for each node on that host as the "nodeMetadataFile" will be out of sync with the cluster metadata.

Usage:
  memsql-admin change-root-password [flags]

Flags:
  -a, --all                  Change the MemSQL root password of all nodes in the cluster
      --fix-secure-key       Reset the secure key
  -h, --help                 Help for change-root-password
      --memsql-id MemsqlID   The MemSQL ID of the node
      --password STRING      The new MemSQL root password for the node

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                    Toolbox configuration file path
      --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-max-sessions POSITIVE_INTEGER   Maximum number of SSH sessions to open per host, must be at least 3
      --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

Remarks

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

Info

The change-root-password command can only be run on nodes in a running process state.
