|
|
# NOTES:
|
|
|
|
|
# 1.Make sure that the MySQL user, who is stopping the mysqld services (e.g
|
|
|
|
|
# using the mysqladmin) have the same password and username for all the
|
|
|
|
|
# data directories accessed (to the 'mysql' database) And make sure that
|
|
|
|
|
# the user has the 'Shutdown_priv' privilege! If you have many data-
|
|
|
|
|
# directories and many different 'mysql' databases with different passwords
|
|
|
|
|
# for the MySQL 'root' user, you may want to create a common 'multi_admin'
|
|
|
|
|
# user for each using the same password (see below). Example how to do it:
|
|
|
|
|
# shell> mysql -u root -S /tmp/mysql.sock -proot_password -e
|
|
|
|
|
# "GRANT SHUTDOWN ON *.* TO multi_admin\@localhost IDENTIFIED BY 'multipass'"
|
|
|
|
|
# You will have to do the above for each mysqld running in each data
|
|
|
|
|
# directory, that you have (just change the socket, -S=...)
|
|
|
|
|
# See more detailed information from chapter:
|
|
|
|
|
# '6 The MySQL Access Privilege System' from the MySQL manual.
|
|
|
|
|
# 2.pid-file is very important, if you are using mysqld_safe to start mysqld
|
|
|
|
|
# (e.g. --mysqld=mysqld_safe) Every mysqld should have it's own pid-file.
|
|
|
|
|
# The advantage using mysqld_safe instead of mysqld directly here is, that
|
|
|
|
|
# mysqld_safe 'guards' every mysqld process and will restart it, if mysqld
|
|
|
|
|
# process fails due to signal kill -9, or similar. (Like segmentation fault,
|
|
|
|
|
# which MySQL should never do, of course ;) Please note that mysqld_safe
|
|
|
|
|
# script may require that you start it from a certain place. This means that
|
|
|
|
|
# you may have to CD to a certain directory, before you start the
|
|
|
|
|
# mysqld_multi. If you have problems starting, please see the script.
|
|
|
|
|
# Check especially the lines:
|
|
|
|
|
# --------------------------------------------------------------------------
|
|
|
|
|
# MY_PWD=`pwd`
|
|
|
|
|
# Check if we are starting this relative (for the binary release)
|
|
|
|
|
# if test -d $MY_PWD/data/mysql -a -f ./share/mysql/english/errmsg.sys -a \
|
|
|
|
|
# -x ./bin/mysqld
|
|
|
|
|
# --------------------------------------------------------------------------
|
|
|
|
|
# The above test should be successful, or you may encounter problems.
|
|
|
|
|
# 3.Beware of the dangers starting multiple mysqlds in the same data directory.
|
|
|
|
|
# Use separate data directories, unless you *KNOW* what you are doing!
|
|
|
|
|
# 4.The socket file and the TCP/IP port must be different for every mysqld.
|
|
|
|
|
# 5.The first and fifth mysqld was intentionally left out from the example.
|
|
|
|
|
# You may have 'gaps' in the config file. This gives you more flexibility.
|
|
|
|
|
# The order in which the mysqlds are started or stopped depends on the order
|
|
|
|
|
# in which they appear in the config file.
|
|
|
|
|
# 6.When you want to refer to a certain group with GNR with this program,
|
|
|
|
|
# just use the number in the end of the group name ( [mysqld# <== )
|
|
|
|
|
# 7.You may want to use option '--user' for mysqld, but in order to do this
|
|
|
|
|
# you need to be root when you start this script. Having the option
|
|
|
|
|
# in the config file doesn't matter; you will just get a warning, if you are
|
|
|
|
|
# not the superuser and the mysqlds are started under *your* unix account.
|
|
|
|
|
# IMPORTANT: Make sure that the pid-file and the data directory are
|
|
|
|
|
# read+write(+execute for the latter one) accessible for *THAT* UNIX user,
|
|
|
|
|
# who the specific mysqld process is started as. *DON'T* use the UNIX root
|
|
|
|
|
# account for this, unless you *KNOW* what you are doing!
|
|
|
|
|
# 8.MOST IMPORTANT: Make sure that you understand the meanings of the options
|
|
|
|
|
# that are passed to the mysqlds and why *WOULD YOU WANT* to have separate
|
|
|
|
|
# mysqld processes. Starting multiple mysqlds in one data directory *WON'T*
|
|
|
|
|
# give you extra performance in a threaded system!
|
|
|
|
|
# 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 /etc/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 can read group [mysqld_multi] from my.cnf file. You may

version 2.10 these options can also be given under groups [mysqld#],

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

The GNR means the group number. You can start, stop or report any GNR,
