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.

       ?   create db_name

           Create a new database named db_name.

       ?   debug

           Tell the server to write debug information to the error log. Format and content of this information is
           subject to change.

           This includes information about the Event Scheduler. See Section 20.4.5, "Event Scheduler Status".

       ?   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-4.1) password-hashing format.
           (See Section 6.1.2.4, "Password Hashing in MySQL".)

       ?   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"

           In MySQL 5.6, the new password can be omitted following the password command. In this case, mysqladmin
           prompts for the password value, which enables you to avoid specifying the password on the command line.
           Omitting the password value should be done only if password is the final command on the mysqladmin command
           line. Otherwise, the next argument is taken as the 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.

       ?   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.

       ?   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 13.7.5.30, "SHOW
           PROCESSLIST Syntax".)

       ?   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 mysqladmin status command result displays the following values:

       ?   Uptime

           The number of seconds the MySQL server has been running.

       ?   Threads

           The number of active threads (clients).

       ?   Questions

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

       ?   Slow queries

           The number of queries that have taken more than long_query_time seconds. See Section 5.4.5, "The Slow Query
           Log".

       ?   Opens

           The number of tables the server has opened.

       ?   Flush tables

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

       ?   Open tables

           The number of tables that currently are open.

       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] groups of an option file. For information about option files used by MySQL programs, see
       Section 4.2.6, "Using Option Files".

       ?   --help, -?

           Display a help message and exit.

       ?   --bind-address=ip_address

           On a computer having multiple network interfaces, use this option to select which interface to use for
           connecting to the MySQL server.

           This option is supported beginning with MySQL 5.6.1.

       ?   --character-sets-dir=dir_name

           The directory where character sets are installed. See Section 10.5, "Character Set Configuration".

       ?   --compress, -C

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

       ?   --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

           Print some debugging information when the program exits.

       ?   --debug-info

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

       ?   --default-auth=plugin

           A hint about the client-side authentication plugin to use. See Section 6.3.7, "Pluggable Authentication".

       ?   --default-character-set=charset_name

           Use charset_name as the default character set. See Section 10.5, "Character Set Configuration".

       ?   --defaults-extra-file=file_name

           Read this option file after the global option file but (on Unix) before the user option file. If the file
           does not exist or is otherwise inaccessible, an error occurs.  file_name is interpreted relative to the
           current directory if given as a relative path name rather than a full path name.

       ?   --defaults-file=file_name

           Use only the given option file. If the file does not exist or is otherwise inaccessible, an error occurs.
           file_name is interpreted relative to the current directory if given as a relative path name rather than a
           full path name.

       ?   --defaults-group-suffix=str

           Read not only the usual option groups, but also groups with the usual names and a suffix of str. For
           example, mysqladmin normally reads the [client] and [mysqladmin] groups. If the
           --defaults-group-suffix=_other option is given, mysqladmin also reads the [client_other] and
           [mysqladmin_other] groups.

       ?   --enable-cleartext-plugin

           Enable the mysql_clear_password cleartext authentication plugin. (See Section 6.5.1.7, "The Cleartext
           Client-Side Authentication Plugin".) This option was added in MySQL 5.6.7.

       ?   --force, -f

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

       ?   --host=host_name, -h host_name

           Connect to the MySQL server on the given host.

       ?   --login-path=name

           Read options from the named login path in the .mylogin.cnf login path file. A "login path" is an option
           group containing options that specify which MySQL server to connect to and which account to authenticate
           as. To create or modify a login path file, use the mysql_config_editor utility. See mysql_config_editor(1).
           This option was added in MySQL 5.6.6.

       ?   --no-beep, -b

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

       ?   --no-defaults

           Do not read any option files. If program startup fails due to reading unknown options from an option file,
           --no-defaults can be used to prevent them from being read.

           The exception is that the .mylogin.cnf file, if it exists, is read in all cases. This permits passwords to
           be specified in a safer way than on the command line even when --no-defaults is used. (.mylogin.cnf is
           created by the mysql_config_editor utility. See mysql_config_editor(1).)

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

       ?   --pipe, -W

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

       ?   --plugin-dir=dir_name

           The directory in which to look for plugins. Specify this option if the --default-auth option is used to
           specify an authentication plugin but mysqladmin does not find it. See Section 6.3.7, "Pluggable
           Authentication".

       ?   --port=port_num, -P port_num

           The TCP/IP port number to use for the connection.

       ?   --print-defaults

           Print the program name and all options that it gets from option files.

       ?   --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".

       ?   --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.

       ?   --secure-auth

           Do not send passwords to the server in old (pre-4.1) format. This prevents connections except for servers
           that use the newer password format. This option is enabled by default; use --skip-secure-auth to disable
           it. This option was added in MySQL 5.6.17.

               Note
               Passwords that use the pre-4.1 hashing method are less secure than passwords that use the native
               password hashing method and should be avoided. Pre-4.1 passwords are deprecated and support for them
               will be removed in a future MySQL release. For account upgrade instructions, see Section 6.5.1.3,
               "Migrating Away from Pre-4.1 Password Hashing and the mysql_old_password Plugin".

       ?   --shared-memory-base-name=name

           On Windows, the shared-memory name to use, for connections made using shared memory to a local server. The
           default value is MYSQL. The shared-memory name is case sensitive.

           The server must be started with the --shared-memory option to enable shared-memory connections.

       ?   --silent, -s

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

       ?   --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.

       ?   --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.

       ?   --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 6.4.5, "Command Options for Secure Connections".

       ?   --user=user_name, -u user_name

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

       ?   --verbose, -v

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

       ?   --version, -V

           Display version information and exit.

       ?   --vertical, -E

           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.

       ?   connect_timeout

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

       ?   shutdown_timeout

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