+#
+#    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
