NAME
       mysqladmin - client for administering a MySQL server

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

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.

	   Beginning with MySQL 5.1.12, this includes information about the Event Scheduler. See
	   Section 19.4.5, "Event Scheduler Status".

       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-4.1)
	   password-hashing format. (See Section 5.3.2.3, "Password Hashing in MySQL".)

       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. (See Section 12.4.5.31, "SHOW PROCESSLIST Syntax".)

       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 MySQL 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. See
	   Section 5.2.5, "The Slow Query Log".

       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
	   MySQL 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 MySQL 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.  mysqladmin also supports the options
       for processing option files described at Section 4.2.3.3.1, "Command-Line Options that
       Affect Option-File Handling".

       o   --help, -?

	   Display a help message and exit.

       o   --character-sets-dir=path

	   The directory where character sets are installed. See Section 9.5, "Character Set
	   Configuration".

       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

	   Print some debugging information when the program exits. This option was added in
	   MySQL 5.1.21.

       o   --debug-info

	   Print debugging information and memory and CPU usage statistics when the program
	   exits. This option was added in MySQL 5.1.14.

       o   --default-character-set=charset_name

	   Use charset_name as the default character set. See Section 9.5, "Character Set
	   Configuration".

       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 MySQL server on the given host.

       o   --no-beep, -b

	   Suppress the warning beep that is emitted by default for errors such as a failure to
	   connect to the server. This option was added in MySQL 5.1.17.

       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. See
	   Section 5.3.2.2, "End-User Guidelines for Password Security". You can use an option
	   file to avoid giving the password on the command line.

       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.

       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. For details on the allowable values, see Section 4.2.2, "Connecting to
	   the MySQL Server".

       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*

	   Options that begin with --ssl specify whether to connect to the server via SSL and
	   indicate where to find SSL keys and certificates. See Section 5.5.6.3, "SSL Command
	   Options".

       o   --user=user_name, -u user_name

	   The MySQL 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 The --set-variable
       format is deprecated and is removed in MySQL 5.5. syntax:

       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).
