# Example MysqL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MysqL plays
# an important part,or systems up to 128M where MysqL is used together with
# other programs (such as a web server)
#
# MysqL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations,see:
# http://dev.MysqL.com/doc/MysqL/en/option-files.html
#
# In this file,you can use all long options that a program supports.
# If you want to know which options a program supports,run the program
# with the "--help" option.

# The following options will be passed to all MysqL clients

# 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
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>

# binary logging - not required for slaves,but recommended
