sub example

print <<EOF;
# 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 MariaDB user, who is stopping the mysqld services, has
# the same password to all MariaDB 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 MariaDB 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 MariaDB 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
# MariaDB 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 MariaDB 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.MariaDB 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 MariaDB 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 C:/Program Files (x86)/MySQL/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 MariaDB 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 --defaults-extra-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
Using: @{[join ' ', @defaults_options]}
--example Give an example of a config file with extra information.
--help Print this help and exit.
--log=... Log file. Full path to and the name for the log file. NOTE:
If the file exists, everything will be appended.
Using: $opt_log
--mysqladmin=... mysqladmin binary to be used for a server shutdown.
Since version 2.10 this can be given within groups [mysqld#]
Using: $mysqladmin
--mysqld=... mysqld binary to be used. Note that you can give mysqld_safe
to this option also. The options are passed to mysqld. Just
make sure you have mysqld in your PATH or fix mysqld_safe.
Using: $mysqld
Please note: Since mysqld_multi version 2.3 you can also
give this option inside groups [mysqld#] in ~/.my.cnf,
where '#' stands for an integer (number) of the group in
question. This will be recognised as a special option and
will not be passed to the mysqld. This will allow one to
start different mysqld versions with mysqld_multi.
--no-log Print to stdout instead of the log file. By default the log
file is turned on.
--password=... Password for mysqladmin user.
--silent Disable warnings.
--tcp-ip Connect to the MariaDB server(s) via the TCP/IP port instead
of the UNIX socket. This affects stopping and reporting.
If a socket file is missing, the server may still be
running, but can be accessed only via the TCP/IP port.
By default connecting is done via the UNIX socket.
--user=... mysqladmin user. Using: $opt_user
--verbose Be more verbose.
--version Print the version number and exit.
--wsrep-new-cluster Bootstrap a cluster.
EOF
exit(0);
