# 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)
