    # 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:
    # 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=, 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 =
    #
    # The port the master is listening on.
