# Example MariaDB config file for very large systems.
|
||||
#
|
||||
# This is for a large system with memory of 1G-2G where the system runs mainly
|
||||
# MariaDB.
|
||||
#
|
||||
# MariaDB 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, do:
|
||||
# 'my_print_defaults --help' and see what is printed under
|
||||
# Default options are read from the following files in the given order:
|
||||
# More information at: 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
|
||||
#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
|
||||
#
|
||||
# binary logging format - mixed recommended
|
