When there is no snapshot of a previous database to import, configure the slave to start the replication from the new master.
To set up replication between a master and a new slave:
Start up the MySQL slave.
CHANGE MASTER TOstatement to set the master replication server configuration. See Section 2.2.7, “Setting the Master Configuration on the Slave”.
Perform these slave setup steps on each slave.
This method can also be used if you are setting up new servers but have an existing dump of the databases from a different server that you want to load into your replication configuration. By loading the data into a new master, the data is automatically replicated to the slaves.
If you are setting up a new replication environment using the data from a different existing database server to create a new master, run the dump file generated from that server on the new master. The database updates are automatically propagated to the slaves:
shell> mysql -h master < fulldb.dump
