- # 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>
