This post explains how to add a new slave to the existing MySQL replication. New slave server can be added to the MySQL replication without stopping master or shutting down existing slave server. You will have to temporarily stop replication on the slave server in order to take the current data snapshot.

MySQL replication can stop if slave fails to execute SQL statement from the binary log. From that moment, slave prints last error and waits for replication recovery. If master has consistent snapshot, then is only necessary to re-point slave to the new master position. It can be done with "change master to" or "sql_slave_skip_counter".
