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 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.
