# 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.

# 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#log-bin=mysql-bin
