NAME
       mysqladmin - client for administering a MariaB server

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

DESCRIPTION
       mysqladmin is a client for performing administrative operations. You
       can use it to check the server's 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.

       o   create db_name

           Create a new database named db_name.

       o   debug

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

           This also includes information about the Event Scheduler.

       o   drop db_name

           Delete the database named db_name and all its tables.

       o   extended-status

           Display the server status variables and their values.

       o   flush-hosts

           Flush all information in the host cache.

       o   flush-logs

           Flush all logs.

       o   flush-privileges

           Reload the grant tables (same as reload).

       o   flush-status

           Clear status variables.

       o   flush-tables

           Flush all tables.

       o   flush-threads

           Flush the thread cache.

       o   kill id,id,...

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

       o   old-password new-password

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

       o   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"

               Caution
               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.

       o   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.

       o   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.

       o   reload

           Reload the grant tables.

       o   refresh

           Flush all tables and close and open log files.

       o   shutdown

           Stop the server.

       o   start-slave

           Start replication on a slave server.

       o   status

           Display a short server status message.

       o   stop-slave

           Stop replication on a slave server.

       o   variables

           Display the server system variables and their values.

       o   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 mysqladmin status command result displays the following values:

       o   Uptime

           The number of seconds the MariaDB server has been running.

       o   Threads

           The number of active threads (clients).

       o   Questions

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

       o   Slow queries

           The number of queries that have taken more than long_query_time
           seconds.

       o   Opens

           The number of tables the server has opened.

       o   Flush tables

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

       o   Open tables

           The number of tables that currently are open.

       o   Memory in use

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

       o   Maximum memory used

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

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

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

       o   --help, -?

           Display help and exit.

       o   --character-sets-dir=path

           The directory where character sets are installed.

       o   --compress, -C

           Compress all information sent between the client and the server if
           both support compression.

       o   --connect-timeout=timeout

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

       o   --count=N, -c N

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

       o   --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'.

       o   --debug-check

           Check memory and open file usage at exit..

       o   --debug-info

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

       o   --default-auth

           Default authentication client-side plugin to use.

       o   --default-character-set=charset_name

           Use charset_name as the default character set.

       o   --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
           option.

       o   --defaults-file=filename

           Set filename as the file to read default options from, override
           global defaults files. Must be given as first option.

       o   --force, -f

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

       o   --host=host_name, -h host_name

           Connect to the MariaDB server on the given host.

       o   --local, -l

           Suppress the SQL command(s) from being written to the binary log by
           enabling sql_log_bin=0 for the session.

       o   --no-beep, -b

           Suppress the warning beep that is emitted by default for errors
           such as a failure to connect to the server.

       o   --no-defaults

           Do not read default options from any option file. This must be
           given as the first argument.

       o   --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
           one.

           Specifying a password on the command line should be considered
           insecure.

       o   --pipe, -W

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

       o   --port=port_num, -P port_num

           The TCP/IP port number to use for the connection or 0 for default
           to, in order of preference, my.cnf, $MYSQL_TCP_PORT, /etc/services,
           built-in default (3306).

       o   --print-defaults

           Print the program argument list and exit. This must be given as the
           first argument.

       o   --protocol={TCP|SOCKET|PIPE|MEMORY}

           The connection protocol to use for connecting to the server. It is
           useful when the other connection parameters normally would cause a
           protocol to be used other than the one you want.

       o   --relative, -r

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

       o   --shutdown-timeouttimeout

           Equivalent of --shutdown_timeout, see the end of this section.

       o   --silent, -s

           Exit silently if a connection to the server cannot be established.

       o   --sleep=delay, -i delay

           Execute commands repeatedly, sleeping for delay seconds in between.
           The --count option determines the number of iterations. If --count
           is not given, mysqladmin executes commands indefinitely until
           interrupted.

       o   --socket=path, -S path

           For connections to localhost, the Unix socket file to use, or, on
           Windows, the name of the named pipe to use.

       o   --ssl

           Enable SSL for connection (automatically enabled with other flags).
           Disable with --skip-ssl.

       o   --ssl-ca=name

           CA file in PEM format (check OpenSSL docs, implies --ssl).

       o   --ssl-capath=name

           CA directory (check OpenSSL docs, implies --ssl).

       o   --ssl-cert=name

           X509 cert in PEM format (check OpenSSL docs, implies --ssl).

       o   --ssl-cipher=name

           SSL cipher to use (check OpenSSL docs, implies --ssl).

       o   --ssl-key=name

           X509 key in PEM format (check OpenSSL docs, implies --ssl).

       o   --ssl-crl=name

           Certificate revocation list (check OpenSSL docs, implies --ssl).

       o   --ssl-crlpath=name

           Certificate revocation list path (check OpenSSL docs, implies
           --ssl).

       o   --ssl-verify-server-cert

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

       o   --user=user_name, -u user_name

           The MariaDB user name to use when connecting to the server.

       o   --verbose, -v

           Verbose mode. Print more information about what the program does.

       o   --version, -V

           Display version information and exit.

       o   --vertical, -E

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

       o   --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

       o   connect_timeout

           The maximum number of seconds before connection timeout. The
           default value is 43200 (12 hours).

       o   shutdown_timeout

           The maximum number of seconds to wait for server shutdown. The
           default value is 3600 (1 hour).
