101
102    ;
103    ; To configure this host as a replication slave, you can choose between
104    ; two methods :
105    ;
106    ; 1) Use the CHANGE MASTER TO command (fully described in our manual) -
107    ;    the syntax is:
108    ;
109    ;    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
110    ;    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
111    ;
112    ;    where you replace <host>, <user>, <password> by quoted strings and
113    ;    <port> by the master's port number (3306 by default).
114    ;
115    ;    Example:
116    ;
117    ;    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
118    ;    MASTER_USER='joe', MASTER_PASSWORD='secret';
119    ;
120    ; OR
121    ;
122    ; 2) Set the variables below. However, in case you choose this method, then
123    ;    start replication for the first time (even unsuccessfully, for example
124    ;    if you mistyped the password in master-password and the slave fails to
125    ;    connect), the slave will create a master.info file, and any later
126    ;    change in this file to the variables' values below will be ignored and
127    ;    overridden by the content of the master.info file, unless you shutdown
128    ;    the slave server, delete master.info and restart the slaver server.
129    ;    For that reason, you may want to leave the lines below untouched
130    ;    (commented) and instead use CHANGE MASTER TO (see above)
131    ;
132    ; required unique id between 2 and 2^32 - 1
133    ; (and different from the master)
134    ; defaults to 2 if master-host is set
135    ; but will not function as a slave if omitted
136    ;server-id       = 2
137    ;
138    ; The replication master for this slave - required
139    ;master-host     =   <hostname>
140    ;
141    ; The username the slave will use for authentication when connecting
142    ; to the master - required
143    ;master-user     =   <username>
144    ;
145    ; The password the slave will authenticate with when connecting to
146    ; the master - required
147    ;master-password =   <password>
148    ;
149    ; The port the master is listening on.
150    ; optional - defaults to 3306
151    ;master-port     =  <port>
