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”.

               Note
               This option is deprecated and will be removed in a future release. As of MySQL
               5.7.5, it is always enabled and attempting to disable it produces an error.

       •   --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).
