# Example MySQL config file for large systems.

# MySQL.
|

|
|
#
|
||
|
|
# You can copy this file to
|
||
|
|
# /etc/my.cnf to set global options,
|
||
|
|
# mysql-data-dir/my.cnf to set server-specific options (in this
|
||
|
|
# installation this directory is /var) or
|
||
|
|
# ~/.my.cnf to set user-specific options.
|
||
|
|
#
|
||
|
|
# In this file, you can use all long options that a program supports.

# Replication Slave (comment out master section to use this)
|
||
|
|
#
|
||
|
|
# To configure this host as a replication slave, you can choose between
|
||
|
|
# two methods :
|
||
|
|
#
|
||
|
|
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
|
||
|
|
# the syntax is:
|
||
|
|
#
|
||
|
|
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
|
||
|
|
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
|
||
|
|
#
|
||
|
|
# where you replace <host>, <user>, <password> by quoted strings and
|
||
|
|
# <port> by the master's port number (3306 by default).
|
||
|
|
#
|
||
|
|
# Example:
|
||
|
|
#
|
||
|
|
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
|
||
|
|
# MASTER_USER='joe', MASTER_PASSWORD='secret';
|
||
|
|
#
|
||
|
|
# OR
|
||
|
|
#
|
||
|
|
# 2) Set the variables below. However, in case you choose this method, then
|
||
|
|
# start replication for the first time (even unsuccessfully, for example
|
||
|
|
# if you mistyped the password in master-password and the slave fails to
|
||
|
|
# connect), the slave will create a master.info file, and any later
|
||
|
|
# change in this file to the variables' values below will be ignored and
|
||
|
|
# overridden by the content of the master.info file, unless you shutdown
|
||
|
|
# the slave server, delete master.info and restart the slaver server.
|
||
|
|
# For that reason, you may want to leave the lines below untouched
|
||
|
|
# (commented) and instead use CHANGE MASTER TO (see above)
|
||
|
|
#
|
||
|
|
# required unique id between 2 and 2^32 - 1
|
||
|
|
# (and different from the master)
|
||
|
|
# defaults to 2 if master-host is set
|
||
|
|
# but will not function as a slave if omitted
|
||
|
|
#server-id = 2
|
||
|
|
#
|
||
|
|
# The replication master for this slave - required
|
||
|
|
#master-host = <hostname>
|
||
|
|
#
|
||
|
|
# The username the slave will use for authentication when connecting
|
||
|
|
# to the master - required
|
||
|
|
#master-user = <username>
|
||
|

#
|
||
|

# The password the slave will authenticate with when connecting to

# the master - required
