NAME

mk-slave-find - Find MySQL replication slaves and execute commands on them.

SYNOPSIS

  mk-slave-find
 
 

DESCRIPTION

mk-slave-find connects to a MySQL replication master and finds its slaves. Currently the only thing it can do is print a tree-like view of the replication hierarchy.

DOWNLOADING

You can download Maatkit from Google Code at <http://code.google.com/p/maatkit/>, or you can get any of the tools easily with a command like the following:
    wget http://www.maatkit.org/get/toolname
    or
    wget http://www.maatkit.org/trunk/toolname
 
 

Where "toolname" can be replaced with the name (or fragment of a name) of any of the Maatkit tools. Once downloaded, they're ready to run; no installation is needed. The first URL gets the latest released version of the tool, and the second gets the latest trunk code from Subversion.

OPTIONS

--askpass
Prompt for a password when connecting to MySQL.
--charset
Enables character set settings in Perl and MySQL. If the value is "utf8", sets Perl's binmode on STDOUT to utf8, passes the "mysql_enable_utf8" option to DBD::mysql, and runs "SET NAMES UTF8" after connecting to MySQL. Any other value sets binmode on STDOUT without the utf8 layer, and runs "SET NAMES" after connecting to MySQL.
--database
Database to use.
--defaults-file
Only read default options from the given file.
--help
Show a brief help message and exit.
--host
Connect to host.
--password
Password to use when connecting.
--port
Port number to use for connection.
--print
Print the replication hierarchy as a tree.
--recurse
Number of levels to recurse in the hierarchy. Default is infinite.

This works by examining the output of "SHOW PROCESSLIST", or "SHOW SLAVE HOSTS" if no slave connections are found.

--setvars
Specify any variables you want to be set immediately after connecting to MySQL. These will be included in a "SET" command.
--socket
Socket file to use for connection.
--user
User for login if not current user.
--version
Output version information and exit.

SYSTEM REQUIREMENTS

You need Perl, DBI, DBD::mysql, and some core packages that ought to be installed in any reasonably new version of Perl.

EXIT STATUS

Successful exit status is 0. Any other value represents the exit status of the Perl process itself.

ENVIRONMENT

The environment variable "MKDEBUG" enables verbose debugging output in all of the Maatkit tools:
    MKDEBUG=1 mk-....
 
 

BUGS

Please use Google Code Issues and Groups to report bugs or request support: <http://code.google.com/p/maatkit/>.

Please include the complete command-line used to reproduce the problem you are seeing, the version of all MySQL servers involved, the complete output of the tool when run with ``--version'', and if possible, debugging output produced by running with the "MKDEBUG=1" environment variable.
