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

Create a new database named db_name.

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”.

Delete the database named db_name and all its tables.

Display the server status variables and their values.

Flush all information in the host cache.

Flush all logs.

Reload the grant tables (same as reload).

Clear status variables.

Flush all tables.

Flush the thread cache.

Kill server threads. If multiple thread ID values are given, there must be no spaces in the list.

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”.)

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"

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.

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”.)

Reload the grant tables.

Flush all tables and close and open log files.

Stop the server.

Start replication on a slave server.

Display a short server status message.

Stop replication on a slave server.

Display the server system variables and their values.

Display version information from the server.

The number of seconds the MySQL server has been running.

The number of active threads (clients).

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

The number of queries that have taken more than long_query_time seconds. See Section 5.2.5, “The Slow Query Log”.

The number of tables the server has opened.

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

The number of tables that currently are open.

The amount of memory allocated directly by mysqld. This value is displayed only when MySQL has been compiled with --with-debug=full.

The maximum amount of memory allocated directly by mysqld. This value is displayed only when MySQL has been compiled with --with-debug=full.

Display a help message and exit.

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

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

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

The number of iterations to make for repeated command execution if the --sleep option is given.

Write a debugging log. A typical debug_options string is ´d:t:o,file_name´. The default is ´d:t:o,/tmp/mysqladmin.trace´.

Print some debugging information when the program exits. This option was added in MySQL 5.1.21.

Print debugging information and memory and CPU usage statistics when the program exits. This option was added in MySQL 5.1.14.

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

Set filename as the file to read default options from after the global defaults files has been read. Must be given as first option.

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

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

Connect to the MySQL server on the given host.

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.

Do not read default options from any option file. This must be given as the first argument.

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.

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

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

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

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 allowable values, see Section 4.2.2, “Connecting to the MySQL Server”.

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.

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

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

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.

For connections to localhost, the Unix socket file to use, or, on Windows, the name of the named pipe to use.

Options that begin with --ssl specify whether to connect to the server via SSL and indicate where to find SSL keys and certificates. See Section 5.5.6.3, “SSL Command Options”.

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

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

Display version information and exit.

Print output vertically. This is similar to --relative, but prints output vertically.

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.

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

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