mysqladmin - client for administering a MariaB server


   mysqladmin [options] command [command-arg] [command [command-arg]] ...


   mysqladmin is a client for performing administrative operations. You
   can use it to check the servers configuration and current status, to
   create and drop databases, and more.

   Invoke mysqladmin like this:

       shell> mysqladmin [options] command [command-arg] [command [command-arg]] ...

   mysqladmin supports the following commands. Some of the commands take
   an argument following the command name.

   *   create db_name

       Create a new database named db_name.

   *   debug

       Tell the server to write debug information to the error log.

       This also includes information about the Event Scheduler.

   *   drop db_name

       Delete the database named db_name and all its tables.

   *   extended-status

       Display the server status variables and their values.

   *   flush-hosts

       Flush all information in the host cache.

   *   flush-logs

       Flush all logs.

   *   flush-privileges

       Reload the grant tables (same as reload).

   *   flush-status

       Clear status variables.

   *   flush-tables

       Flush all tables.

   *   flush-threads

       Flush the thread cache.

   *   kill id,id,...

       Kill server threads. If multiple thread ID values are given, there
       must be no spaces in the list.

   *   old-password new-password

       This is like the password command but stores the password using the
       old (pre MySQL 4.1) password-hashing format.

   *   password new-password

       Set a new password. This changes the password to new-password for
       the account that you use with mysqladmin for connecting to the
       server. Thus, the next time you invoke mysqladmin (or any other
       client program) using the same account, you will need to specify
       the new password.

       If the new-password value contains spaces or other characters that
       are special to your command interpreter, you need to enclose it
       within quotes. On Windows, be sure to use double quotes rather than
       single quotes; single quotes are not stripped from the password,
       but rather are interpreted as part of the password. For example:

           shell> mysqladmin password "my new password"

           Do not use this command used if the server was started with the
           --skip-grant-tables option. No password change will be applied.
           This is true even if you precede the password command with
           flush-privileges on the same command line to re-enable the
           grant tables because the flush operation occurs after you
           connect. However, you can use mysqladmin flush-privileges to
           re-enable the grant table and then use a separate mysqladmin
           password command to change the password.

   *   ping

       Check whether the server is alive. The return status from
       mysqladmin is 0 if the server is running, 1 if it is not. This is 0
       even in case of an error such as Access denied, because this means
       that the server is running but refused the connection, which is
       different from the server not running.

   *   processlist

       Show a list of active server threads. This is like the output of
       the SHOW PROCESSLIST statement. If the --verbose option is given,
       the output is like that of SHOW FULL PROCESSLIST.

   *   reload

       Reload the grant tables.

   *   refresh

       Flush all tables and close and open log files.

   *   shutdown

       Stop the server.

   *   start-slave

       Start replication on a slave server.

   *   status

       Display a short server status message.

   *   stop-slave

       Stop replication on a slave server.

   *   variables

       Display the server system variables and their values.

   *   version

       Display version information from the server.

   All commands can be shortened to any unique prefix. For example:

       shell> mysqladmin proc stat
       | Id | User  | Host      | db | Command | Time | State | Info             |
       | 51 | monty | localhost |    | Query   | 0    |       | show processlist |
       Uptime: 1473624  Threads: 1  Questions: 39487
       Slow queries: 0  Opens: 541  Flush tables: 1
       Open tables: 19  Queries per second avg: 0.0268

       The number of active threads (clients).

   *   Questions

       The number of questions (queries) from clients since the server was

   *   Slow queries

       The number of tables the server has opened.

   *   Flush tables

       The number of flush-*, refresh, and reload commands the server has

   *   Open tables

       The number of tables that currently are open.

       The amount of memory allocated directly by mysqld. This value is
       displayed only when MariaDB has been compiled with

   *   Maximum memory used

       The maximum amount of memory allocated directly by mysqld. This
       value is displayed only when MariaDB has been compiled with

   If you execute mysqladmin shutdown when connecting to a local server
   using a Unix socket file, mysqladmin waits until the servers process
   ID file has been removed, to ensure that the server has stopped

   mysqladmin supports the following options, which can be specified on
   the command line or in the [mysqladmin] and [client] option file

   *   --help, -?

       Display help and exit.

   *   --character-sets-dir=path

       Equivalent to --connect_timeout, see the end of this section.

   *   --count=N, -c N

       The number of iterations to make for repeated command execution if
       the --sleep option is given.

   *   --debug[=debug_options], -# [debug_options]

       Write a debugging log. A typical debug_options string is
       d:t:o,file_name. The default is d:t:o,/tmp/mysqladmin.trace.

   *   --debug-check

       Check memory and open file usage at exit..

   *   --debug-info

       Print debugging information and memory and CPU usage statistics
       when the program exits.

       Default authentication client-side plugin to use.

   *   --default-character-set=charset_name

       Use charset_name as the default character set.

   *   --defaults-extra-file=filename

       Set filename as the file to read default options from after the
       global defaults files has been read.  Must be given as first

   *   --defaults-file=filename

       global defaults files. Must be given as first option.

   *   --force, -f

       Do not ask for confirmation for the drop db_name command. With
       multiple commands, continue even if an error occurs.

       given as the first argument.

   *   --password[=password], -p[password]

       The password to use when connecting to the server. If you use the
       short option form (-p), you cannot have a space between the option
       and the password. If you omit the password value following the
       --password or -p option on the command line, mysqladmin prompts for

       Specifying a password on the command line should be considered

   *   --pipe, -W

       On Windows, connect to the server via a named pipe. This option
       applies only if the server supports named-pipe connections.

   *   --port=port_num, -P port_num

       useful when the other connection parameters normally would cause a
       protocol to be used other than the one you want.

   *   --relative, -r

       Show the difference between the current and previous values when
       used with the --sleep option. Currently, this option works only

       Certificate revocation list path (check OpenSSL docs, implies

   *   --ssl-verify-server-cert

       Verify server's "Common Name" in its cert against hostname used
       when connecting. This option is disabled by default.

       Print output vertically. This is similar to --relative, but prints
       output vertically.

   *   --wait[=count], -w[count]

       If the connection cannot be established, wait and retry instead of
       aborting. If a count value is given, it indicates the number of
       times to retry. The default is one time.

   You can also set the following variables by using --var_name=value
