First, the triggers that exist on a master must be recreated on the slave server. Once this is done, the replication flow works as any other standard DML statement that participates in replication. For example, consider a table EMP that has an AFTER insert trigger, which exists on a master MySQL server. The same EMP table and AFTER insert trigger exist on the slave server as well.

Again, this depends on whether you are using statement-based or row-based replication. Statement-based replication. First, the triggers that exist on a master must be re-created on the slave server.
