MemSQL Helios does not support this command.
Change the root password for a node on a host.
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: sdb-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: sdb-admin change-root-password [flags] Flags: -a, --all Change the database 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 node ID of the node on which to change the root password --password STRING The new database root password for the node. If a password is specified on the command line, it must not contain an unescaped '$' character as it will be replaced by the shell 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 colored output in console, which some terminal sessions/environments may have issues 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-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
This command is interactive unless you use either the
flags to override interactive behavior.
change-root-password command can only be run on nodes in a
running process state.
