 # information.  If InnoDB requires more memory for this purpose it will

 # too large, though, because competition of the physical memory may

 # cause paging in the operating system.  Note that on 32bit systems you

 # 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
