# example mysql config file for large systems.
#
# this is for a large system with memory = 512m where the system runs mainly
# mysql.
#
# 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
[client]
#password = your_password
port = 3307
socket = /tmp/mysql.sock
# here follows entries for some specific programs
# the mysql server

# 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=, master_port=,
# master_user=, master_password= ;
#
# where you replace , , by quoted strings and
# 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 =
#
# the username the slave will use for authentication when connecting
# to the master - required
#master-user =
#
# the password the slave will authenticate with when connecting to
# the master - required
#master-password =
