NAME

       mysqladmin - client for administering a MariaB server

SYNOPSIS

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

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.

           This also includes information about the Event Scheduler.

       ·   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 MySQL
           4.1) password-hashing format.

       ·   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.

       ·   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.

       ·   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.

       ·   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 MariaDB 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.

       ·   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
           MariaDB has been compiled with --with-debug=full.

       ·   Maximum memory used

           The maximum amount of memory allocated directly by mysqld. This value is displayed
           only when MariaDB 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.

       ·   --help, -?

           Display help and exit.

       ·   --character-sets-dir=path

           The directory where character sets are installed.

       ·   --compress, -C

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

       ·   --connect-timeout=timeout

           Equivalent to --connect_timeout, see the end of this section.

       ·   --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

           Check memory and open file usage at exit..

       ·   --debug-info

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

       ·   --default-auth

           Default authentication client-side plugin to use.

       ·   --default-character-set=charset_name

           Use charset_name as the default character set.

       ·   --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.

       ·   --defaults-file=filename

           Set filename as the file to read default options from, override global defaults files.
           Must be given as first option.

       ·   --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 MariaDB server on the given host.

       ·   --local, -l

           Suppress the SQL command(s) from being written to the binary log by enabling
           sql_log_bin=0 for the session.

       ·   --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 default options from any option file. This must be given as the first
           argument.

       ·   --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.

       ·   --pipe, -W

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

       ·   --port=port_num, -P port_num

           The TCP/IP port number to use for the connection or 0 for default to, in order of
           preference, my.cnf, $MYSQL_TCP_PORT, /etc/services, built-in default (3306).

       ·   --print-defaults

           Print the program argument list and exit. This must be given as the first argument.

       ·   --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.

       ·   --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.

       ·   --shutdown-timeouttimeout

           Equivalent of --shutdown_timeout, see the end of this section.

       ·   --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

           Enable SSL for connection (automatically enabled with other flags). Disable with
           --skip-ssl.

       ·   --ssl-ca=name

           CA file in PEM format (check OpenSSL docs, implies --ssl).

       ·   --ssl-capath=name

           CA directory (check OpenSSL docs, implies --ssl).

       ·   --ssl-cert=name

           X509 cert in PEM format (check OpenSSL docs, implies --ssl).

       ·   --ssl-cipher=name

           SSL cipher to use (check OpenSSL docs, implies --ssl).

       ·   --ssl-key=name

           X509 key in PEM format (check OpenSSL docs, implies --ssl).

       ·   --ssl-crl=name

           Certificate revocation list (check OpenSSL docs, implies --ssl).

       ·   --ssl-crlpath=name

           Certificate revocation list path (check OpenSSL docs, implies --ssl).

       ·   --ssl-verify-server-cert

           Verify server's "Common Name" in its cert against hostname used when connecting. This
           option is disabled by default.

       ·   --user=user_name, -u user_name

           The MariaDB 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).
