- # This is an example of a my.cnf file for $my_progname.
- # Usually this file is located in home dir ~/.my.cnf or /etc/my.cnf
- #
- # SOME IMPORTANT NOTES FOLLOW:
- #
- # 1.COMMON USER
- #
- # Make sure that the MySQL user, who is stopping the mysqld services, has
- # the same password to all MySQL servers being accessed by $my_progname.
- # This user needs to have the 'Shutdown_priv' -privilege, but for security
- # reasons should have no other privileges. It is advised that you create a
- # common 'multi_admin' user for all MySQL servers being controlled by
- # $my_progname. Here is an example how to do it:
- #
- # GRANT SHUTDOWN ON *.* TO multi_admin\@localhost IDENTIFIED BY 'password'
- #
- # You will need to apply the above to all MySQL servers that are being
- # controlled by $my_progname. 'multi_admin' will shutdown the servers
- # using 'mysqladmin' -binary, when '$my_progname stop' is being called.
- #
- # 2.PID-FILE
- #
- # If you are using mysqld_safe to start mysqld, make sure that every
- # MySQL server has a separate pid-file. In order to use mysqld_safe
- # via $my_progname, you need to use two options:
- #
- # mysqld=/path/to/mysqld_safe
- # ledir=/path/to/mysqld-binary/
- #
- # ledir (library executable directory), is an option that only mysqld_safe
- # accepts, so you will get an error if you try to pass it to mysqld directly.
- # For this reason you might want to use the above options within [mysqld#]
- # group directly.
- #
- # 3.DATA DIRECTORY
- #
- # It is NOT advised to run many MySQL servers within the same data directory.
- # You can do so, but please make sure to understand and deal with the
- # underlying caveats. In short they are:
- # - Speed penalty
- # - Risk of table/data corruption
- # - Data synchronising problems between the running servers
- # - Heavily media (disk) bound
- # - Relies on the system (external) file locking
- # - Is not applicable with all table types. (Such as InnoDB)
- # Trying so will end up with undesirable results.
- #
- # 4.TCP/IP Port
- #
- # Every server requires one and it must be unique.
- #
- # 5.[mysqld#] Groups
- #
- # In the example below the first and the fifth mysqld group was
- # intentionally left out. You may have 'gaps' in the config file. This
- # gives you more flexibility.
- #
- # 6.MySQL Server User
- #
- # You can pass the user=... option inside [mysqld#] groups. This
- # can be very handy in some cases, but then you need to run $my_progname
- # as UNIX root.
- #
- # 7.A Start-up Manage Script for $my_progname
- #
- # In the recent MySQL distributions you can find a file called
- # mysqld_multi.server.sh. It is a wrapper for $my_progname. This can
- # be used to start and stop multiple servers during boot and shutdown.
- #
- # You can place the file in /etc/init.d/mysqld_multi.server.sh and
- # make the needed symbolic links to it from various run levels
- # (as per Linux/Unix standard). You may even replace the
- # /etc/init.d/mysql.server script with it.
- #
- # Before using, you must create a my.cnf file either in @sysconfdir@/my.cnf
- # or /root/.my.cnf and add the [mysqld_multi] and [mysqld#] groups.
- #
- # The script can be found from support-files/mysqld_multi.server.sh
- # in MySQL distribution. (Verify the script before using)

- $my_progname version $VER by Jani Tolonen
-
- Description:
- $my_progname can be used to start, or stop any number of separate
- mysqld processes running in different TCP/IP ports and UNIX sockets.
-
- $my_progname can read group [mysqld_multi] from my.cnf file. You may
- want to put options mysqld=... and mysqladmin=... there. Since
- version 2.10 these options can also be given under groups [mysqld#],
- which gives more control over different versions. One can have the
- default mysqld and mysqladmin under group [mysqld_multi], but this is
- not mandatory. Please note that if mysqld or mysqladmin is missing
- from both [mysqld_multi] and [mysqld#], a group that is tried to be
- used, $my_progname will abort with an error.
-
- $my_progname will search for groups named [mysqld#] from my.cnf (or
- the given --config-file=...), where '#' can be any positive integer
- starting from 1. These groups should be the same as the regular
- [mysqld] group, but with those port, socket and any other options
- that are to be used with each separate mysqld process. The number
- in the group name has another function; it can be used for starting,
- stopping, or reporting any specific mysqld server.
-
- Usage: $my_progname [OPTIONS] {start|stop|report} [GNR,GNR,GNR...]
- or $my_progname [OPTIONS] {start|stop|report} [GNR-GNR,GNR,GNR-GNR,...]
-
- The GNR means the group number. You can start, stop or report any GNR,
- or several of them at the same time. (See --example) The GNRs list can
- be comma separated or a dash combined. The latter means that all the
- GNRs between GNR1-GNR2 will be affected. Without GNR argument all the
- groups found will either be started, stopped, or reported. Note that
- syntax for specifying GNRs must appear without spaces.
-
- Options:
-
- These options must be given before any others:
- --no-defaults Do not read any defaults file
- --defaults-file=... Read only this configuration file, do not read the
- standard system-wide and user-specific files
- --defaults-extra-file=... Read this configuration file in addition to the
- standard system-wide and user-specific files
