+# 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
+# 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
+#
+# binary logging format - mixed recommended
