       mysqladmin - client for administering a MySQL server


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


       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.

           This includes information about the Event Scheduler. See Section 18.4.5, “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, “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"

           As of MySQL 5.5.3, 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.

               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, “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 5.2.5, “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.

       ·   Memory in use

           The amount of memory allocated directly by mysqld. This value is displayed only when
           MySQL has been compiled with safemalloc, which is available only before MySQL 5.5.6.

       ·   Maximum memory used

           The maximum amount of memory allocated directly by mysqld. This value is displayed
           only when MySQL has been compiled with safemalloc, which is available only before
           MySQL 5.5.6.

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

       ·   --help, -?

           Display a help message and exit.

       ·   --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. It is not available in standard MySQL Server 5.5 releases.

       ·   --character-sets-dir=path

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

       ·   --compress, -C

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

       ·   --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

       ·   --default-auth=plugin

           The client-side authentication plugin to use. See Section 5.5.6, “Pluggable

           This option was added in MySQL 5.5.9.

       ·   --default-character-set=charset_name

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

       ·   --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.

       ·   --no-beep, -b

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

       ·   --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, “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=path

           The directory in which to look for plugins. It may be necessary to specify this option
           if the --default-auth option is used to specify an authentication plugin but
           mysqladmin does not find it. See Section 5.5.6, “Pluggable Authentication”.

           This option was added in MySQL 5.5.9.

       ·   --port=port_num, -P port_num

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

       ·   --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.

       ·   --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, “SSL Command

       ·   --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

       You can also set the following variables by using --var_name=value The --set-variable
       format is deprecated and was removed in MySQL 5.5.3. syntax:

       ·   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).
