MySQL 8.4 Release Notes
25.5.18 ndb_print_file — 打印 NDB 磁盘数据文件内容
ndb_print_file obtains information from an NDB Cluster Disk Data file.
ndb_print_file [-v] [-q] file_name+file_name is the name of an NDB Cluster Disk Data file. Multiple filenames are accepted, separated by spaces.
Like ndb_print_schema_file and ndb_print_sys_file (and unlike most of the other NDB utilities that are intended to be run on a management server host or to connect to a management server) ndb_print_file must be run on an NDB Cluster data node, since it accesses the data node file system directly. Because it does not make use of the management server, this utility can be used when the management server is not running, and even when the cluster has been completely shut down.
ndb_print_file supports the following options:
-
--file-key,-KCommand-Line Format --file-key=hex_dataSupply file system encryption or decryption key from
stdin,tty, or amy.cnffile. -
Command-Line Format --file-key-from-stdinType Boolean Default Value FALSEValid Values TRUESupply file system encryption or decryption key from
