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 quotation marks. On Windows, be sure to use double quotation
	   marks rather than single quotation marks; single quotation marks
	   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 available. 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.

FBMYSQLADMINFR(1)     MySQL Database System	FBMYSQLADMINFR(1)

       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:

MySQL 5.1		    11/29/2010				3

FBMYSQLADMINFR(1)     MySQL Database System	FBMYSQLADMINFR(1)

       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, -?

MySQL 5.1		    11/29/2010				4

FBMYSQLADMINFR(1)     MySQL Database System	FBMYSQLADMINFR(1)

	   Display a help message and exit.

       o   --bind-address=ip_address

	   On a computer having multiple network interfaces, this option can
	   be used to select which interface is employed when connecting to
	   the MySQL server.

	   This option is supported only in the version of mysqladmin that is
	   supplied with MySQL Cluster, beginning with MySQL Cluster NDB
	   6.3.4. It is not available in standard MySQL 5.1 releases.

       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   --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   --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

MySQL 5.1		    11/29/2010				5

FBMYSQLADMINFR(1)     MySQL Database System	FBMYSQLADMINFR(1)

	   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   --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 using 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   --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
	   permissible 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. This option works only with the
	   extended-status command.

       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.

MySQL 5.1		    11/29/2010				6

FBMYSQLADMINFR(1)     MySQL Database System	FBMYSQLADMINFR(1)

       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 using 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.

       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).
